What do these subduction zones have in common?
This animation explores three major mechanisms for earthquakes in South America due to the interaction of the Nazca and South American plates.
Más de una cuarta parte de los terremotos más significativos de todo el mundo, magnitud 8 o mayores, se han producido en el oeste de Sudamérica. Es el lugar de origen del megaterremoto de magnitud 9,5 ocurrido en Chile en 1960, siendo este el terremoto más grande jamás registrado, y con una serie de terremotos generados por procesos tectónicos de placa e intra-placa.
Causes and casualties of the 14 most-significant earthquakes of that decade. This Flash rollover reveals facts about each of the earthquakes.
This rollover compares the an earthquake of 1700 in the Pacific Northwest with the 2004 Sumatra earthquake and tsunami. The tectonic settings are similar.
Learn how the Pacific Northwest tectonic setting and megathrust earthquake of January 1700 is similar to the catastrophic earthquake in Japan in 2011 by touching icons on this interactive map.
