Short summary
Short summary
Three months after the April 12, 2022 landslide and tsunami disaster in Pilar, Abuyog, Leyte, Philippines, we studied it by integrating the analysis from various field data, eyewitness accounts, videos, and documentary sources to reconstruct the timeline of the events and to describe the processes that led to the destruction of the village. We found that after many days of prolonged rainfall, at least two major landslides occurred, buried Pilar and generated tsunamis as they reached the sea.

Short summary
The ground movement and rupture produced by the 2020 Masbate earthquake in the Philippines were studied using satellite data. We highlight the importance of the complementary use of optical and radar datasets. The slip measurements and field observations helped improve our understanding of the seismotectonics of the region, which is critical for seismic hazard studies.
