The eruption of the Hunga Tonga–Hunga Ha'apai volcano in January 2022 triggered a global phenomenon, including an atmospheric wave and a volcano-meteorological tsunami (VMT). The tsunami, reaching as far as Callao, Peru, 10 000 km away, caused significant coastal impacts. This study delves into understanding these effects, particularly on vessel mooring safety. The findings underscore the importance of enhancing early warning systems and preparing port authorities for managing such rare events.

We investigate the source of the 1761 earthquake and tsunami. The reanalysis of the tsunami travel times agrees with an earlier suggested source area. We check the geodynamic setting of the area and place a fault as an extension to an identified fault and use numerical modelling to distinguish between two candidate sources. One of our theories is compatible with the geodynamic setting and reproduces well the observed tsunami parameters.

In this work, we present a methodology to compute a synthetic catalog of tsunami waveforms. To do this, we compute a synthetic earthquake catalog that respects the kinematics of the plate boundary. We use a method to do the fast computation of tsunami waveforms for all events of the synthetic waveform catalog. The method can be used in similar geological environments.

This is a new study on the 25 November 1941 earthquake and tsunami, Northeast Atlantic. The tsunami was recorded from Morocco to the UK. We present a new epicentre location and use tsunami data to compute the tsunami source. Results show that the earthquake ruptured a segment of the Eurasia–Nubia plate boundary. Other segments of the plate boundary may rupture and generate similar events. These conclusions are important for tsunami hazard assessment in the Northeast Atlantic.
