A strong magnitude-5.7 temblor that was felt on Sunday at 2 p.m., and four more quakes registered on Monday are aftershocks from the magnitude-7.6 earthquake that hit the Nicoya Peninsula last year, according to the Volcanological and Seismological Observatory of Costa Rica (OVSICORI).
The epicenter of Sunday’s temblor was Nicoya, in the northwestern province of Guanacaste. According to reports from OVSICORI, that quake was felt almost entirely across the country.
On Monday, the first quake was recorded at 12:25 a.m. with a magnitude-2.6, located in Liberia, Guanacaste.
At 7:37 a.m., a magnitude-2.3 quake was registered in the canton of San Carlos, in the northeastern region. A few minutes later, at 7:58, a magnitude-3.2 hit Nicoya again. Finally, a strong magnitude-4.1 quake was felt in the province of Alajuela, at 9:43 a.m.
The Sept. 5Â earthquake struck five miles off the coast of the Nicoya Peninsula at 8:42 a.m., shaking most of the country for 45 seconds. It caused nearly $45 million in damage and minor injuries. A 51-year old woman died of a heart attack following the event, although she was not included in the official quake death toll.
