The eastern offshore of Martinique is one of the active areas of the Lesser Antilles Subduction Zone (LASZ). Although its seismicity is moderate compared to other subduction zones, LASZ is capable of generating a M 7+ interplate earthquake and recent studies and historical events, such as the M 8 1839 and M 7-7.5 1946 earthquakes, confirm this...

The impact of earthquakes can be severely aggravated by cascading secondary hazards. The 2018 urn:x-wiley:grl:media:grl60058:grl60058-math-0003 7.5 Palu, Indonesia, earthquake led to devastating tsunamis and landslides, while triggered submarine landslides possibly contributed substantially to generate the tsunami. The rupture was supershear...

The 2015 Mw 7.8 Gorkha, Nepal earthquake is the largest event to have struck the capital city of Kathmandu in recent times. One of its surprising features was the frequency content of the recorded ground motion, exhibiting a notable amplification at low frequencies (<2 Hz) and a contrasting depletion at higher frequencies. The latter has been...

The international project PRENOLIN is focused on verification and validation of numerical codes for ground motion simulations including nonlinear soil rheologies. In this particular study, we present implementations of the elasto-plastic Iwan model (Iwan, 1967) into numerical schemes based on finite-difference, finite element, spectral element...

An earthquake of magnitude 5 (Mw 4.9) occurred near the town of Le Teil, France on November 11 2019, causing damage locally and concern due to its proximity to nuclear facilities. Despite its moderate magnitude, this earthquake offers unique opportunities to advance basic and applied research on earthquakes in general, including our...
