Catastrophic events, such as earthquakes, tsunamis, and volcanic eruptions, are caused by movements of tectonic plates in Earth's sublayers. These natural disasters can destroy Earth's surfaces and human-made structures and cause additional problems and dangers for people near them. While not all damage from these events can be prevented, some devices and strategies can be used to help reduce the effect. Think about ways people can protect their environments from damage caused by these catastrophic events.

These geologic events occur when tectonic plates are displaced, causing the ground to tremble violently. Shock absorbers can be added to the foundations and each floor of buildings to reduce magnitude of vibrations.:

Sea walls can be built to redirect wave energy back to the sea. These series of massive waves generated in oceans are caused by tectonic plate shifts. These are sudden occurrences of violent discharges of steam and other material from large vents in the earth.:

When lava and gas are released from the Earth—sometimes explosively. Reinforce the roof of houses to better bear the weight of volcanic ash.:
