This week Costa Rica experienced several moderate earthquakes with thousands of after shocks, which is not usual for this Central American nation. What is usual is that Guacalito River located near Armenia de Upala simply disappeared and turned into a muddy mess.
The government is investigating if the river disappeared into some kind of sink hole or if the earth’s rattling dried the river up. Either way it is very usual for this to happened say experts. The US Geological Survey confirmed that there were three earthquakes on July 12th, measuring 5.0, 5.1 and 5.6 in magnitude.
