A Reuters report on Monday evening indicated that a 5.8 magnitude earthquake had hit the South Amercican nation of Costa Rica at 4.55 a.m. local time. The report added that there were no reports of injuries or damage, as yet. A U.S. Geological Survey (USGS) report said the epicenter of the quake was 75km (46m) south of the capital of San Jose, off the coast of a harbour city Porto Quepos. The epicentre was also reported as being 17 miles below the Earth's surface.

Meanwhile, reports in the Huffington Post and The Los Angeles Times confirmed that an earthquake had struck the state of California in the United States. The LA Times indicated a 5.6 magnitude quake occurred at 1.07 p.m. local time and lasted for 10 seconds. Once again, fortunately, there were no reports of damage or injuries, as yet. The Huffington Post report quoted the USGS as saying the epicenter was a rural area near the small community of Weitchpec, on the Hoopa Valley Indian Reservation, about 240 miles north of San Francisco and about 60 miles south of the Oregon border.
