Describe how earthquakes are caused
WebEarthquakes can cause the ground to shake and crack apart. Earthquakes can be very powerful. And if they occur in or near areas where people live, they can make buildings collapse, bridges sway, and roads buckle. ... Scientists describe the intensity of an earthquake using the Richter Scale. It measures earthquakes on a scale of 1 to 10. … WebBoth volcanoes and earthquakes occur due to movement of the Earth’s tectonic plates. They are both caused by the heat and energy releasing from the Earth’s core. Earthquakes can trigger volcanic eruptions through severe movement of tectonic plates. Similarly, volcanoes can trigger earthquakes through the movement of magma within a volcano.
