7.5 earthquake near Sand Point, Alaska prompts tsunami warning

October 20, 2020: A magnitude 7.5 earthquake near Sand Point, Alaska Peninsula triggered a tsunami warning causing locals to evacuate to higher ground. According to the U.S. Geological Survey (USGS), the earthquake’s epicenter was located in the North Pacific Ocean about 55 miles southeast of Sand Point. The earthquake caused a tsunami warning along roughly 500 miles of the Alaska Peninsula coastline . The warning extended from Kennedy Entrance, 40 miles southwest of Homer, to Unimak Pass, 80 miles northeast of Unalaska. The tsunami waves reached a height of 2.2 feet above the tide in Sand Point. According to the USGS, the 7.5 earthquake in Alaska occurred as the result of strike-slip faulting near the subduction zone interface between the Pacific and North America plates, either within the upper (North America) Plate or within the downgoing (Pacific) slab.  Large earthquakes are common in the Alaska-Aleutian subduction zone. Eight earthquakes of magnitude greater than magnitude 7.0 h

Westmorland, California earthquake swarm: More than 240 earthquakes recorded

October 1, 2020: More than 240 earthquakes have been recorded near Westmorland, California. A 4.9 magnitude earthquake is the latest and strongest earthquake to strike near Westmorland. According to the United States Geological Survey (USGS), the epicenter of the magnitude 4.9 earthquake was located 4 km NE of Westmorland, California. The earthquake swarm began around 4 p.m., when a 3.0 magnitude temblor struck. At least 240 earthquakes were recorded by 8 p.m. USGS confirmed that the earthquake and the associated swarms are located in an area of diffuse seismic activity between the San Andreas fault in the north and the Imperial fault to the south.  It’s less likely, but possible, that a larger quake with a magnitude up to 6.9 will strike, according to the earthquake forecast by the USGS. According to the USGS, the latest swarm is “rapidly evolving,” and seismologists will update their quake forecast as more data is collected. Tremors were felt by the people of San Diego County and Ti
