A significant earthquake of 5.1 magnitude took place Monday at 10:29 p.m. on the west shore of Lake Nicaragua near Rivas, said the Laboratorio de Ingenieria Sismica.
That is a seismically active area, and earthquaketrack.com said that the country to the north has had six quakes in the last seven days. Some were offshore.
The quake was felt in Costa Rica with moderate intensity in Nosara, Paquera, Santa Cruz, Cañas and Nicoya, said the Laboratorio. The epicenter was estimated to be 52.1 kilometers north northeast of La Cruz at the Costa Rican border.
The location of the quake appeared to be on a fault that runs north from the mouth of the Gulf of Nicoya.
