Last night (22 April – Tuesday, 9:00 p.m. local time) an earthquake hit off the coast of São Paulo State. 5.2 on the Richter scale, which is kind of small time as earthquakes go, but for Brazil, this is an “attention getting”. It was felt in Rio, Santa Catarina and Paraná States. Some in São Paulo City even fed their apartments and stayed out on the streets.
This is unusual for Brazil. The strongest earthquake in Brazil occured in 1955 (6.2 on the Richter scale), the region of Portos Gaúchos, an isolate area in the State of Mato Grosso.
Prof. George Sand de França, of the Observatório Sismológico da UnB – Universidade de Brasília, says these events happen about every 10 years.
