2018 Anchorage earthquake
The 2018 Anchorage earthquake was a 7.1 magnitude earthquake that hit Anchorage in South Central Alaska. The earthquake's epicenter was near Point Mackenzie, about 10 miles (16 km) north of Anchorage, and occurred at a depth of 29 miles (47 km). It was followed six minutes later by a magnitude 5.7 aftershock centered 2.5 miles (4.0 km) north-northwest of the municipality. The earthquake could be felt as far away as Fairbanks. The National Tsunami Warning Center-itself located inside the quake zone, in Palmer, Alaska, 42 miles (68 km) northeast of Anchorage-issued tsunami warnings for nearby coastal areas, including Cook Inlet and the Kenai Peninsula, but they were lifted shortly after.
