San Jose:
A strong earthquake rocked communities along Costa Rica's Pacific coast, but there were no immediate reports of damage or casualties and no tsunami warning was issued.
The 6.2-magnitude quake's epicenter was 67 kilometres south-southwest of the Costa Rican capital San Jose at a depth of 38 kilometres, the US Geographical Survey said.
"It was felt strongly in (the towns of) Puntarenas, Perez Zeledon and Bahia Drake, but none of these places have reported falling objects or major damage," Costa Rican seismologist Esteban Chavez said.
The quake occurred where the Cocos plate under the Pacific Ocean is moving against the Panamanian micro-plate, Chavez said.
A 6.2 magnitude earthquake shook Costa Rica on January 8 killing 23 people, leaving seven missing and causing more than USD 100 million in damages.
That was the strongest quake to shake the popular ecotourism and beach holiday destination in the last 150 years and was followed by several aftershocks and collapsed homes in and around the capital.
