Widespread deformation of basin-plain sediments in Aysén fjord (Chile) due to impact by earthquake-triggered, onshore-generated mass movements

► Basin‐wide landsliding and basin‐plain deformation triggered by the 2007 Aysén earthquake ► Unique type of basin‐plain deformation due to impact by onshore landslides ► Basin‐plain deformation might be more tsunamogenic than onshore landslides ► Paleoseismological reconstruction in Aysén fjord
