Guanacaste residents got a rude wakeup call Saturday when a moderate earthquake took place offshore in the Pacific.
The Observatorio Vulcanológico y Sismológico de Costa Rica said the quake happened six minutes before 8 a.m. They placed the epicenter 35 kilometers northwest of Matapalo in Santa Cruz. That’s about 22 miles.
Residents characterized it as a real shaker, but there were no reports of damage.
The U.S. Earthquake Information Center estimated the magnitude at 4.9, but the local observatory said 5.5. It also said the quake was caused by the subduction of a tectonic plate, as are most of the Pacific quakes.
