This document discusses a class on structural dynamics and earthquake engineering. It provides information on natural and manmade sources of earthquakes, including tectonic earthquakes, volcanic earthquakes, rock falls, collapse of cavities, explosives, reservoirs, and mining. It also notes that the Indian plate is moving northeast at 5 cm per year while the Eurasian plate moves north at 2 cm per year, causing deformation and compression that results in Mount Everest increasing in height by 2cm annually.
