California is prone to earthquakes because it’s located on the Pacific Ring of Fire.
The Ring of Fire is a long chain of volcanoes and other tectonically active structures that surround the Pacific Ocean. The chain runs up along the western coast of South and North America, crosses over the Aleutian Islands in Alaska, runs down the eastern coast of Asia past New Zealand and into the northern coast of Antarctica. The Ring of Fire is one of the most geologically active areas on Earth, and is a site for frequent earthquakes and powerful volcanic eruptions.
There are more than 450 active and dormant volcanoes located within the Ring of Fire. Many of these volcanoes were created through the tectonic process of subduction whereby dense ocean plates collide with and slide under lighter continental plates.
The material from the ocean floor melts as… click here to read the full article from EarthSky >>
