A magnitude-5.7 earthquake hit off the coast of Northern California according to the U.S. Geological Survey in an update at 4 p.m. ET on Friday.

The quake hit at around 5.6 miles in depth, according to the agency.

The quakes appear too far offshore to cause any damage. It's unclear if a tsunami warning was issued. It hit about 150 miles off the coast of California.

The Sacramento Bee wrote that after Tuesday's devastating earthquake in Mexico, it noted that smaller quakes shook parts of California. "The West Coast is bracing for the worst."

"Time spoke to experts who pointed out that Southern California, Los Angeles and San Francisco were the most at-risk areas in the country for the next destructive quake. It's been 160 years since the magnitude 7.9 earthquake near the San Andreas Fault, meaning a lot of pressure has built up over the years," it reports.

It added:
On the central coast, a magnitude 3.2 quake hit San Juan Bautista on Wednesday morning, and a magnitude 2.8 earthquake rumbled between Gilroy and Morgan Hill about 10 a.m. Thursday, television station KSBW-8 reported. Stronger earthquakes were reported in Northern California, with a magnitude 3.8 earthquake reported in Shasta County and a 3.0 in Humboldt County.
It comes after several large earthquakes hit Paupa New Guinea, Indonesia, Vanuatu, Japan, and New Zealand.

A 7.1-magnitude earthquake hit Mexico City earlier this week, killing more than 200 people.


The quakes occurred along the Pacific "Ring of Fire," a region prone to earthquakes and volcanic activity.

The Pacific "Ring of Fire," meanwhile is in the basin of the Pacific Ocean with some 450 volcanoes. About 90 percent of the world's earthquakes strike along the "Ring of Fire."
