A shake alert went out over the U.S. Geological Survey's early warning system on Dec. 4, warning that a 5.9 earthquake near Carson City in western Nevada could produce heavy shaking in the region.

A series of earthquakes rattled California’s Bay Area near Gilroy on Wednesday, according to the U.S. Geological Survey. The largest was a magnitude 4.0 quake centered about 8 kilometers east of Gilroy, followed by a magnitude 3.6 quake southeast of the city and a magnitude 2.7 event to the east.

The earthquakes happened near San Juan Bautista in San Benito County, according to the U.S. Geological Survey (USGS). Here are the specific earthquake details, listed in descending order on the magnitude scale, according to information provided by the USGS:

When the island of Santorini was rattled by thousands of small earthquakes earlier this year, many people were left mystified about the source of the tremors. The shaking lasted more than a month and forced more than 10,000 people to evacuate the Greek island.

The glacier's collapse could severely impact coastal cities worldwide due to rising sea levels. Scientists have recently detected hundreds of earthquakes on the continent. According to a new study, a vast number of tremors were recorded in Antarctica between 2010 and 2023,
