This volume presents a collection of contributions that were published in Pure and Applied
Geophysics - pageoph and which deals with the major earthquake that hit Illapel Chile on
September 16 2015 with magnitude 8.3 and associated trans-oceanic tsunami. The subducting
Nazca plate beneath the Andes caused this major earthquake generating strong shaking
permanent deformation free oscillations of the Earth and tsunamis. This event occurred in the
flat-angle subducting segment of the plate.The generated tsunami spread throughout the entire
Pacific Ocean and was recorded by numerous coastal tide gauges and open-ocean DART stations.
All articles give an up-to-date account of research in one of the most active seismic zones
worldwide. An introductory article by Kenji Satake rounds this collection off.
