Here are 13 causes of earthquakes in Indonesia. Rocks at plate margins are in constant motion. This sudden release of energy causes the seismic waves that make the ground shake. However, Surface waves consist of several major types and are known as long waves. Cause of the earthquake. In areas underlain by water-saturated sediments, large earthquakes, usually magnitude 6.0 or greater, may cause liquefaction. Since the shear and tear forces are always constant within the earth’s plate tectonics, earthquakes can occur at any time. When a big earthquake hits, it can be devastating—entire cities can be levelled, not to mention the loss of human lives. The Earth’s outer shell is made up of huge slabs called t ectonic plates, which are constantly moving due to convection currents triggered by molten lava inside the earth’s crust. 4.
