11min Novice

Why do scientists forecast another Great earthquake on the subduction zone?

The Sunda Subduction Zone has a long history of devasting Great earthquakes. This animation looks at recent studies of past earthquakes near the Sunda Subduction Zone boundary and how past earthquakes can give a key to understanding the potential for future earthquakes.

Keypoints:

  • Overview of the Sunda Subduction-zone and the Sumatra fault.
  • Subduction-zone earthquakes can trigger tsunamis.
  • Tsunami earthquakes triggers tsunamis even when only gentle rocking motions are felt.
  • Intra-plate earthquakes are common here.
  • The Sunda Subduction zone is one of the most well-studied due to the Sumatran geodetic array and coral studies.
  • Hazard mitigation and emergency preparedness and resilience strategies for a forecasted Great Earthquake are suggested.
