On Thursday morning, a magnitude-7.0 earthquake ruptured off the coast of California, triggering a tsunami warning for Northern California and southern Oregon. The quake was relatively shallow, occurring about 6 miles beneath the Earth’s surface, and was followed by a magnitude 5.8 earthquake near Cobb, California. The tsunami warning extended from Davenport, California, to the border between Douglas and Lane counties in Oregon. Earthquakes can cause tsunamis by displacing the seafloor, creating waves that move towards land. Harold Tobin, director of the Pacific Northwest Seismic Network, described the earthquake as a strike-slip event, occurring in the Mendocino fault zone where three plates intersect. It was noted as possibly the largest earthquake in the region since the 1990s. The situation remains developing, and updates will be provided as the story progresses. Evan Bush, a science reporter for NBC News, is closely monitoring and reporting on the events related to the earthquake and tsunami warning off the coast of California.
