Coincidentally, as I sat down to report on this morning’s 5.6 magnitude Oklahoma, U.S. quake, I was rocked by the 5.3 magnitude quake that was just registered 15 km north of Domincal, Quepos, in the Puntarenas province of Costa Rica.
Over 100 Facebook comments were posted on the Dominical quake in the first 10 minutes after it was posted on the Ovsicori site. It was felt strongly in many parts of San José, Heredia, and even Alajuela.
The National University’s Volcanology and Seismology Institute (Ovsicori-UNA) listed the tremor as occurring at 4:06 p.m. at a depth of 18 km.
The closest town to the quake is San Isidro de el General, Pérez Zeledón, 19.2 km to the east of the epicenter.
A Facebook reader in Pérez Zeledón described the quake “As if a leveller were coming near your house, and then, the earth shook!” And another reader in Hatillo said the things on their shelves were rattling. In Barva de Heredia there was a report of items falling from shelves, and in Montes de Oca one reader reported a chair tipping over.
Many readers described it as one short shake, followed by a long rocking movement that lasted around 30 seconds.
