Short summary
We microzoned seismic hazard of the City of Kolkata, India by integrating seismological, geological and geotechnical themes in GIS which in turn is integrated with the vulnerability components in a logic-tree framework for the estimation of both the socio-economic and structural risk of the City. The cumulative damage probabilities in terms of ‘none’, ‘slight’, ‘moderate’, ‘extensive’ and ‘complete’ have been assessed for the predominantly four model building types RM2L, RM2M, URML and URMM.

To reduce the consequences of landslides due to rainfall, such as of life and economic losses, and disruption of order of our daily living; this study describes the process of building a machine learning model which can help to estimate the volume of landslides material that can occur in a particular region taking into account of antecedent rainfall, soil characteristics, type of vegetation etc. The findings can be useful for land use, infrastructure design and rainfall disaster management.

This study performed analysis on typhoon-induced coastal morphodynamics for the Mokpo coast. Wetland vegetation was severely impacted by Typhoon Soulik, with 87.35 % of shoreline transects experiencing seaward migration. This result highlights the fact that sediment resuspension controls the land alteration process over the typhoon period. The land accretion process dominated during the pre- to post-typhoon periods.

The prediction of the size of rainfall-induced debris in South Korea was analyzed. The model suitability was carried out and Random forest was the most suitable for the Size of debris prediction. The most contributing factor in the model was slope length and the most vulnerable region to higher frequency and severe debris was Gangwon province. The findings may be used for rainfall induced-debris prevention policies and post-disaster rehabilitation planning.
