Tsunami warning lifted after 7.0 magnitude earthquake rocks California
FirstpostAt least 5.3 million people in the state were under a tsunami warning after the earthquake. The tremors were first felt at 10:44 am in the west of Ferndale, a small city in coastal Humboldt County near the Oregon border The United States National Weather Service has lifted the briefly imposed tsunami warning for the West Coast after a 7.0 magnitude earthquake rocked the state of California. According to the USGS analysis of the situation, the tremors were first felt at 10:44 am in the west of Ferndale, a small city in coastal Humboldt County near the Oregon border. One of the main reasons California gets jolted by earthquakes frequently is that the state is located near an area where three different tectonic plates — the North American plate, the Pacific plate and the Juan de Fuca plate — come together. According to Jones, the Thursday earthquake occurred because of horizontal motion between the Juan de Fuca plate and the Pacific plate.
