A 5.8-magnitude natural disaster struck on Monday (Nov 13) off the east coast of northern Japan at 6.24am (Singapore time), according to the US Geological Survey (USGS).
Costa Rica's National Emergency Commission said it is monitoring the situation. The USGS estimates that, based on its size, it is likely to cause casualties and tens of millions of dollars of damage. There have been no immediate reports of deaths or injuries in Costa Rica.
Costa Rican President Luis Guillermo Solis said authorities were gathering information and asked residents to remain calm and to be prepared for any possible aftershocks.
The Pacific Tsunami Warning Center did not issue a tsunami alert.
Costa Rica regularly suffers from strong earthquakes.
According to USGS, a strong quake has struck southwest off the coast of Costa Rica hours after the disastrous tremor hit the border area between Iran and Iraq. At least 75 people were killed, over 550 were injured and nearly 10,000 people left homeless as a result.
