Earthquakes Subduction-zone mega-thrust earthquakes, the most powerful earthquakes in the world, can produce tsunamis through a variety of structures that are missed by simple models including: fault boundary rupture, deformation of overlying plate, splay faults, and landslides during earthquakes. From a hazards viewpoint, it is critical to remember that tsunamis are multiple waves that often arrive on shore for many hours after the initial wave.In this animation we explore different tsunami-pro

What is a megathrust earthquake? Subduction zone megathrust earthquakes, the most powerful earthquakes in the world, can produce tsunamis through a variety of structures that are missed by simple models. These include fault boundary rupture, deformation of overlying plate, splay faults and landslides. In this animation, we explore the three different tsunami-producing mechanisms by examining three famous earthquakes: Japan 2011, Chile 2010, and Alaska 2014. From a hazards viewpoint, it is critic
