Following a series of moderate earthquakes that struck the country Tuesday, residents around the Guacalito River in Costa Rica discovered that the river had disappeared. Earthquake-report.com reported that sometime after the earthquakes, villagers living near the river, which is located near Armenia de Upala, discovered that the river was dry.
It was not immediately known if the waters of the river had disappeared due to sinkhole activity that can occur after earthquakes or if the earth shaking caused damming that dried up the river near the Miravalles volcano. The quakes were centered near the Nicaragua and Costa Rica border in the same vicinity as the Miravalles volcano.
We really need to name this new theory. Suggestions welcome.
