An earthquake about 70 miles deep struck in the mountains of southern Alaska on Wednesday and could be felt hundreds of miles away, geology officials said.
The 5.8-magnitude earthquake occurred at about 2:30 p.m. local time Wednesday -- and was felt in Anchorage, about 75 miles away, and even Fairbanks, which is 250 miles away, the U.S. Geological Survey said.
No incidents of major damage or injury were reported. Earthquakes are common in Alaska, experts say, due to the convergence of multiple underground tectonic plates in a seismic region called the Aleutian Arc.
"This region exhibits intense volcanic activity and has a history of megathrust earthquakes," the U.S. Geological Survey said. "Since 1900, this region has hosted twelve large earthquakes."
A magnitude 4.2 earthquake centered in Fontana was reported Saturday morning, according to the U.S. Geological Survey. The temblor occurred at 5:54 a.m. The quake's magnitude was initially reported as 4.3.
According to the USGS, the epicenter was located under a stretch of Merrill Avenue that connects Sierra and Fontana avenues. It was followed by two small aftershocks
Residents reported feeling a sharp jolt. According to the USGS's Did You Feel It? database, most of responses were from Fontana and nearby Bloomington, Rancho Cucamonga, Rialto and San Bernardino.
In the past 10 days, there has been one earthquake of magnitude 3.0 or greater centered nearby.
