Tsunami waveforms contain the features of its source, propagation path, and local topography. On 4 March 2021, two tsunamis were generated by earthquakes in the Kermadec Islands, New Zealand, within 2 h. This rare case gives us a valuable opportunity to study the characteristics of two tsunamis. We analyzed the records of two tsunamis at tide gauges with spectral analysis tools. It is found that two tsunamis superpose during the few hours after the arrival of the second tsunami.

The Flores Thrust lies along the north coasts of Bali and Lombok. We model how an earthquake on this fault could trigger a tsunami that would impact the regional capital cities of Mataram and Denpasar. We show that for 3–5 m of slip on the fault (a Mw 7.5–7.9+ earthquake), the cities would experience a wave ca. 1.6–2.7 and ca. 0.6–1.4 m high, arriving in < 9 and ca. 23–27 min, respectively. They would also experience subsidence of 20–40 cm, resulting in long-term exposure to coastal hazards.

Port industries are extremely vulnerable to coastal hazards such as tsunamis. Despite their pivotal role in local and global economies, there has been little attention paid to tsunami impacts on port industries. For the first time, tsunami damage data are being extensively collected for port structures and catalogued into a database. The study also provides fragility curves which describe the probability of damage exceedance for different port industries given different tsunami intensities.

The accuracy of tsunami hazard assessments is highly dependent on the reliability of earthquake source models. In this study, we combine the most updated geological and geophysical data of the Manila subduction zone to propose a series of possible rupture scenarios. These rupture models facilitate an improved understanding of the potential tsunami hazard in the South China Sea. The results highlight the grave consequences faced by the SCS, one of the world's most densely populated coastlines.

Typhoon Hato was one of the most damaging natural disaster events in the western Pacific region in 2017. It caused the the worst flooding in Macau since its instrumental records began in 1925. We present a high-resolution survey map recording inundation depths and distances at 278 sites in Macau. We provide a series of inundation maps under different tidal and sea levels. The maps that highlight adaptive strategies are essential in order to keep up with the pace of rising sea level.

After the 1783 Laki eruption, excess mortality in Iceland was one-sixth of the population, traditionally explained by famine due to livestock loss. Since 1970, it has been suggested that 1) fluorine poisoning may have contributed to mortality in Iceland and 2) air pollution might have caused excess deaths in both Iceland and Europe. Reviewing contemporary Icelandic demographic data, air pollution simulations, and medical records on fluorosis, we show that evidence for both hypotheses is weak.

Submarine volcanic eruptions represent the majority of eruptions taking place on Earth. Still, they are vastly understudied worldwide. Here we compile a new dataset and assess the morphology, depth, and height of submarine volcanoes in Southeast Asia and its surroundings to understand their hazard-exposure potential in the region. This study will serve as a stepping stone for future quantitative hazard assessments from submarine eruptions in Southeast Asia and neighbouring countries.

Global navigation satellite system signals are used to measure the perturbations induced in the ionosphere by earthquakes related to volcanic eruptions. The study uses data from ground stations and satellites measuring the signals reflected on the ocean or during radio occultation. The results shows a small correlation, but given the small magnitude of the earthquakes, it is difficult to apply this concept to any practical application that finds earthquake proxies in ionospheric perturbations.

The lava eruption at Fagradalsfjall in 2021 was the most visited eruption in Iceland, with thousands of visitors per day for 6 months. To address the short- and long-term danger of lava inundating infrastructure and hiking paths, we used the lava flow model MrLavaLoba before and during the eruption. These simulations helped communicate lava hazards to stakeholders and can be used as a case study for lava hazard assessment for future eruptions in the area, which are likely to be more destructive.

A new methodology to calculate a probabilistic long-term tephra fallout hazard assessment in southern Italy from the Neapolitan volcanoes is provided. By means of thousands of numerical simulations we quantify the mean annual frequency with which the tephra load at the ground exceeds critical thresholds in 50 years. The output hazard maps account for changes in eruptive regimes of each volcano and are also comparable with those of other natural disasters in which more sources are integrated.

Lava fountains at the Etna volcano are explosive eruptions that pose a serious threat to civil infrastructure and aviation. Their evolution from weak explosion to sustained eruptive column is imprinted in tiny ground deformations caught by strain signals with diverse duration and amplitude. By performing a clustering analysis on strain variations, we discover a transition among four eruptive styles, providing useful hints for volcano monitoring and hazard assessment.

Natural hazards can have negative impacts on mental health. We used artificial intelligence to analyse sentiments expressed by people in Twitter posts during a period of heightened earthquake activity and during a small volcanic eruption in Iceland. We show even small natural hazards which cause no material damage can still have a significant impact on people . The earthquakes had a predominantly negative impact but, somewhat unexpectedly, the eruption seemed to have a positive impact.

Assessing risk to crops from volcanic ashfall is critical to protect people who rely on agriculture for their livelihood and food security. Ash retention on crop leaves is a key process in damage initiation. Experiments with tomato and chilli pepper plants revealed that ash retention increases with decreasing ash grain size and is enhanced when leaves are pubescent or their surfaces are wet. We propose a new relationship to quantify potential crop yield loss as a function of ash retention.

Here, we delve into the properties of a lake-breakout mass flow that grew up to a volume of ~ 4.4 × 106 m3 over the course of 83 km that occurred on 18 March 2007 at Mt. Ruapehu, Aotearoa / New Zealand. The combination of seismic analysis (frequency and directionality) with on-the-ground measurements (e.g., video, sediment concentration) shows how a lahar evolves over time and distance and how using seismic techniques can help monitor the ever-changing dynamics and properties of a flow event.

In this paper, 20 explosive volcanic eruption scenarios of differing location and magnitude are simulated to investigate tsunami generation in Lake Taupō, New Zealand. A non-hydrostatic multilayer numerical scheme resolves the highly dispersive generated wavefield. Inundation, hydrographic and related hazard outputs are produced, indicating that significant inundation around the lake shore begins above 5 on the volcanic explosivity index.

We evaluate through first-order kinetic energy models, the minimum volume and mass of a pyroclastic density current generated at the Aso caldera that might affect any of five distal infrastructure sites. These target sites are all located 115–145 km from the caldera, but in well-separated directions. Our constraints of volume and mass are then compared with the scale of Aso-4, the largest caldera-forming eruption of Aso.

This paper focuses on the issue of population information about natural hazards and disaster risk. It builds on the analysis of the unique seismo-volcanic crisis on the island of Mayotte, France, that started in May 2018 and lasted several years. We document the gradual response of the actors in charge of scientific monitoring and risk management. We then make recommendations for improving risk communication strategies in Mayotte and also in contexts where comparable geo-crises may happen.

There is a need for large-scale comparable assessments of volcanic threat, but previous approaches assume circular hazard to exposed population. Our approach quantifies and ranks five exposure types to four volcanic hazards for 40 volcanoes in Southeast Asia. Java has the highest median exposure, with Merapi consistently ranking as the highest-threat volcano. This study and the tools developed provide a road map with the possibility to extend them to other regions and/or towards impact and loss.

Evacuation planning and management represent a key aspect of volcanic crises because they can increase people's protection as well as minimize the potential impacts on the economy, properties and infrastructure of the affected area.

The monitoring of ash dispersion in the atmosphere is an important task for satellite remote sensing since ash represents a threat to air traffic.

This algorithm, trained on realistic observations simulated with a radiative transfer model, runs operationally at the German Weather Service.

This work addresses a quantitative hazard assessment on the possible impact on air traffic of a future ash-forming eruption on the island of Jan Mayen.

Eruption forecasting and volcanic hazard analysis are pervaded by uncertainty of different kinds, such as the natural randomness, our lack of knowledge, and the so-called unknown unknowns. After discussing the limits of how classical probabilistic frameworks handle these uncertainties, we put forward a unified probabilistic framework which unambiguously defines uncertainty of different kinds, and it allows scientific validation of the hazard model against independent observations.

Computer simulations can be used to estimate the flow path and inundation of volcanic mass flows; however, their accuracy needs to be appropriately measured and handled in order to determine hazard zones. This paper presents an approach to simulation accuracy assessment and hazard zonation with a volcanic debris avalanche as the benchmark. This method helped to identify and support key findings about errors in mass flow simulations, as well as potential end-use cases for hazard zonation.

At Piton de la Fournaise, eruptions are typically fissure-fed and form extensive lava flow fields. Most historical events have occurred inside an uninhabited caldera, but rarely has lava flowed where population and infrastructure might be at risk. We present an up-to-date lava flow hazard map to visualize the probability of inundation by a lava flow per unit area that is an essential tool for hazard mitigation and guiding crises response management.

This study proposes a new approach to accessing the economic impact of explosive eruptions on the tourism sector on São Miguel Island, which uses the loss present value method to estimate the benefits generated by accommodation units over 30 years for different scenarios. The results reveal that in a near-total-destruction scenario, the economic loss is ~ EUR 145 million. This method can be adapted to other volcanic regions and also to other geological hazards and economic sectors.

Often, an abrupt increase in shallow seismicity at volcanoes is seen as an indicator for magmatic intrusions into the upper crust. If no eruption occurs and the seismic activity stops, this is called a failed eruption. Here, we report a failed eruption of Brava, Cabo Verde, in August 2016. We remotely monitored the seismicity of Brava with a seismic array, operating from October 2015 to December 2016. Other episodes with increased seismicity around the island were also observed during the study.

Awu is a little-known volcano in Indonesia, and paradoxically it is one of the deadliest volcanoes on Earth. Some of its recurrent intense eruptions have induced world-scale impacts. The pulverization of a cooled lava dome and its conduit plug have allowed lake water injection into the conduit, leading to explosive water–magma interaction. The past vigorous eruptions were likely induced by these phenomena and it is a possible scenario for future events.

This paper starts by showing the present low performance of eruption forecasting and then addresses the problem of effectively mitigating the highest volcanic risk in the world, represented by the Naples area (southern Italy). The problem is considered in a highly multidisciplinary way, taking into account the main economic, sociological and urban planning issues. Our study gives precise guidelines to assessing and managing volcanic risk in any densely urbanised area.

TROPOMI satellite measurements can accurately determine the height of thick volcanic ash clouds from a short-lived volcanic eruption of the Sinabung volcano in Indonesia. Standard geostationary satellite detection of volcanic ash was limited due to the presence of water and ice in the upper parts of volcanic ash clouds, a known issue. The TROPOMI satellite measurements do not suffer from this limitation, hence providing information where standard geostationary volcanic ash detection is limited.

Phreatic eruptions often occur without signs of enhanced volcanic unrest, avoiding detection and posing a threat to people in the vicinity. We analyzed data of the 2015 phreatic eruption of Lascar volcano, Chile, to retrospectively identify a precipitation event as the trigger mechanism and potential signs heralding this minor eruption. We showed that it is possible to detect the precursory activity of phreatic eruptions by deploying appropriate multiparametric monitoring.

Lahars are fast-moving mixtures of volcanic debris and water propagating downslope on volcanoes that can be very dangerous for people and property. Identification of lahar source areas and initiation mechanisms is crucial to comprehensive lahar hazard assessment. We present the first rain-triggered lahar susceptibility map for La Fossa volcano (Vulcano, Italy) combining probabilistic tephra modelling, slope-stability modelling, precipitation data, field characterizations, and geotechnical tests.

In this work, we present new methods for calculating the mean, standard deviation, median, and modal locations of the boundaries of volcanic hazards. These calculations are based on a new, mathematically rigorous definition of probabilistic hazard maps – a way to map the probabilities of inundation by a given hazard. We apply this analysis to several models of volcanic flows: simple models of viscous flows, complex models of a tabletop granular flow, and a complex model of a volcanic mud flow.

Hazard maps provide information about the probability of given areas of being affected by hazards. So far studies combining hazard mapping with accessibility to services are few. In this study, we propose two new metrics defining the importance of each road segment in the accessibility of services, taking into account the probability of being affected by a hazard. These metrics may help support discussions about the development of new infrastructure or road segments and evacuation procedures.

The fallout of large clasts (> 5 cm) from the margins of eruptive plumes can damage local infrastructure and severely injure people close to the volcano. Even though this potential hazard has been observed at many volcanoes, it has often been overlooked. We present the first hazard and risk assessment of large-clast fallout from eruptive plumes and use Mt Etna (Italy) as a case study. The use of dedicated shelters in the case of an explosive event that occurs with no warning is also evaluated.

At Merapi volcano, lava dome failure may generate pyroclastic flow and threaten populations who live on its flanks. Here, we assessed the potential hazard of the Merapi lava dome by using drone photogrammetry and numerical modeling. Results show a weak structural depression that is associated with high thermal imaging in the southern Merapi lava dome sector. The southern lava dome sector may be further destabilized by typical rainfall at the Merapi summit and produce pyroclastic flow up to 4 km.

The most challenging aspect of forecasting volcanic eruptions is the correct identification and interpretation of precursors during the episodes that normally precede eruptive activity. We show an easy and useful approach to the understanding of the information recorded by the monitoring system and show how this information can be used to forecast an eruption and its potential hazards in real time. This methodology can be used to facilitate communication between scientists and decision-makers.

The advection of volcanic emissions plays a crucial role in climate research, air traffic control and human wellbeing. In contrast to already existing volcanic emission dispersion models relying on a fixed grid, the application of an adaptive mesh enables us to simulate the advection of volcanic emissions with a high local resolution while minimizing computational cost.

Lanzarote is an island (Canaries, Spain), that has hosted the largest and longest eruption in the archipelago (Timanfaya 1730–36). It brought severe economic losses and forced local people to migrate. We have developed the first comprehensive hazard assessment for the island. New eruptions will take place close to the last one and will be characterised by Strombolian activity, with ash emission towards the S, medium-length lava flows and hydromagmatic activity only close to the coastal areas.

Atmospheric dispersal of a gas denser than air can threat the environment and surrounding communities. In complex terrains, microscale winds and local orographic features can have a strong influence on the gas cloud behavior, potentially leading to inaccurate model results if not captured by coarser-scale simulations. We introduce a methodology for microscale wind field characterization and validate it using, as a test case, the CO2 gas dispersal from 1986 Lake Nyos eruption.

Volcanic mudflows, called lahars, can cause large amounts of damage to buildings. In this research we developed a method to estimate lahar-induced building damage based on the height, speed and amount of volcanic material in the lahar. This method was applied to a small region in Arequipa, Peru, where computer models were used to estimate the number of buildings affected by lahars. The research found that building location and the size of the flow are most important in determining damage.

The 2011 Puyehue volcano eruption also caused persisting chemical impacts. By 2012, dental fluorosis in deer appeared, with bone fluoride increasing > 38-fold. Livestock also succumbed to fluorosis. As exposure of ruminants continued, bone fluoride reached 10 396 ppm, by 2014 caused skeletal fluorosis, reduced wool growth, and caused major losses among periparturient cattle. Peculiarities of digestive processes make ruminants susceptible to fluoride-containing ashes.

The eruption in June 2011 of the Puyehue-Cordón Caulle Volcanic Complex (Chile) impacted air traffic around the Southern Hemisphere for several months. The ash deposited in vast areas of the Patagonian steppe was subjected to the strong wind conditions prevalent during the austral winter and spring. An ash resuspension event impacted Buenos Aires and resulted in the closure of airports in the area on 16 October 2011. Measurements of aerosol properties clearly indicate the enhanced concentrations

We provide a comprehensive lava flow hazard assessment for Fogo volcano, Cabo Verde before and after the 2014–2015 eruption based on probabilistic lava flow simulations. We find that the probability of lava flow invasion has not decreased at the location of two villages that were destroyed during this eruption, but have already started to be rebuilt. Our findings will be important for the next eruption of Fogo volcano and have implications for future lava flow crises elsewhere in the world.

A total of 11 lahars occurred during this period of time, and their erosion/deposition effects were quantified by means of cross sections and rainfall analysis. The major factors controlling the E/D rates are the channel-bed slope, the cross-section width, the flow depth and the joint effect of sediment availability and accumulated rainfall.

Earthquakes of volcanic origin (VT) represent a significant hazard in volcanic islands prone to landslides. We present a methodology to forecast large VT earthquakes during volcanic crises based on an algorithm that translates fluctuations of the level of seismicity into 10-day time windows of increased probability of a major event. This algorithm has been successfully applied during the 2011–2013 volcanic crisis at El Hierro (Canary Islands).

The Kamchatka volcano group is located near populated areas and international air routes. Due to this, explosive eruptions are a serious threat to their security. To decrease the risks, effective systems for remote detection of eruptions are necessary. WWLLN resolution is enough for the remote sensing of the volcano lightning activity in the early stage of ash cloud formation a few minutes after the eruption when electrification proceeds the most intensively.

The paper focuses on the potential health risks caused by the sub-10 micron fraction of volcanic ash (PM10) following explosive eruptions of Mt. Etna (Italy). We present the results of a study on the ash concentration in the air of urbanized areas after the 15 November 2011 lava fountain and the related tephra fallout, causing high levels of PM10 in the air. We conclude by hoping that due attention will be given to the impact of ash fallout on the Etnean territory in the future.

Short summary
We explore the tsunamigenic mechanisms and the hydrodynamic characteristics of the 2022 Hunga Tonga–Hunga Ha'apai volcanic tsunami event. Through extensive analysis of tsunami waveforms, we identify four distinct tsunami components from different physical mechanisms. The long-lasting oscillation of the tsunami event in the Pacific Ocean was mainly associated with the interplay of the ocean waves left by atmospheric waves with local bathymetry.
We explore the tsunamigenic mechanisms and the hydrodynamic characteristics of the 2022 Hunga...
