Earthquakes are known to be catastrophic events. However, they are one of the main reasons why we have life on Earth. Moreover, we “see” what lies beneath our feet down to the center of the Earth and other planetary bodies such as Mars and the Moon. Find out what and how we can learn about Earth’s and planetary interiors using seismic waves generated by earthquakes (or marsquakes, moonquakes, etc. for other planets) focusing on Earth’s crust and mantle down to the core-mantle boundary at about 2900 km depth, exploring subduction zones and mantle plumes which directly control the plate tectonics and volcanism that shape the surface of our planet.
