The 1970 Peru earthquake occurred at a convergent boundary, where the Nazca Plate is subducting beneath the South American Plate. This tectonic interaction leads to significant seismic activity, resulting in powerful earthquakes. The 1970 event was particularly devastating, causing widespread destruction and loss of life.

The strength of an earthquake is more correctly termed it's magnitude and is measured using a magnitude scale. Currently seismologists use the moment magnitude scale (which was developed to replace the Richter scale in the 1970's). The magnitude sclae is a way of representing the energy emitted during an earthquake. The damage and perceived ground shaking in an earthquake is known as it's intensity and this is measured using the Modified Mercalli scale or (in Europe) the Macroseismic scale. For more information on the types of magnitude and intensity scales, please see the related questions.

The Peru earthquake in 1970 had a magnitude of 7.9 and caused devastating damage in the region. It resulted in the loss of approximately 70,000 lives and significant destruction to infrastructure and buildings.
