Earthquakes have occurred recently.
It happens more frequently than you might think. This month, South Africa had more than 40 earthquakes, including a 4.2 magnitude quake southeast of Springbok in the Northern Cape.
According to Volcano Discovery, there were two earthquakes with magnitudes of 8.2 and 6.1 in the last 24 hours, as well as 12 quakes with magnitudes of 5.0 and 6.0 and 65 quakes with magnitudes of 4.0 and 5.0.
The epicenter of the largest earthquake in the past 24 hours was in the Gulf of Alaska, making it the greatest US quake in 50 years. Tsunami warnings were issued for South Alaska and Hawaii.
Earthquake in Alaska
The earthquake struck 91 kilometers southeast of Perryville, according to the USGS, and a tsunami warning was issued for south Alaska and the Alaskan peninsula.
Residents of Kodiak were seen fleeing to higher ground in videos published on social media, while tsunami warning sirens blared in the background. A buoy in the region’s southwest corner detected “significant variations” in the water level.
The earthquake has an intermediate depth of 35 kilometers, according to Dr Alice-Agnes Gabriel, a seismologist at the Ludwig-Maximilians-Universität (LMU) in Germany, which is higher than the USGS phase estimate of 23 kilometers.
