Validation of seismic hazard curves using a calibrated 14 ka lacustrine record in the Eastern Alps, Austria [PDF]
Scientific Reports, 2022 Seismic hazard maps are crucial for earthquake mitigation and mostly rely on probabilistic seismic hazard analysis (PSHA). However, the practise and value of PSHA are under debate because objective testing procedures for seismic hazard maps are scarce ...

Variable-resolution building exposure modelling for earthquake and tsunami scenario-based risk assessment: an application case in Lima, Peru [PDF]
Natural Hazards and Earth System Sciences, 2021 We propose the use of variable resolution boundaries based on central Voronoi tessellations (CVTs) to spatially aggregate building exposure models for risk assessment to various natural hazards.

Scenario-based multi-risk assessment from existing single-hazard vulnerability models. An application to consecutive earthquakes and tsunamis in Lima, Peru [PDF]
Natural Hazards and Earth System Sciences, 2023 Multi-hazard risk assessments for building portfolios exposed to earthquake shaking followed by a tsunami are usually based on empirical vulnerability models calibrated on post-event surveys of damaged buildings.

Remote structural characterization of thousands of buildings from San Jose, Costa Rica
Frontiers in Built Environment, 2022 The present work shows the implementation of a data collection strategy for characterizing large amounts of buildings efficiently by the conduction of remote surveys on 360° panoramic images and aerial photographs. A set of 7,296 buildings from the Latin

An improved Probabilistic Seismic Hazard Assessment of Tripura, India [PDF]
Pure and Applied Geophysics, 2022, 2022 The State of Tripura lies in northeast India which is considered to be one of the most seismically active regions of the world. In the present study, a realistic Probabilistic Seismic Hazard Assessment (PSHA) of Tripura State based on improved seismogenic sources considering layered polygonal sources corresponding to hypo-central depth range of 0 to 25

Stress field sensitivity analysis in a sedimentary sequence of the Alpine foreland, northern Switzerland [PDF]
Solid Earth, 2015 The stress field at depth is a relevant parameter for the design of subsurface constructions and reservoir management. Yet the distortion of the regional stress field due to local-scale features such as sedimentary and tectonic structures or topography ...
