River Missing In Upala, Costa Rica
On July 12th, 2011 Costa Rica had a 5.3 magnitude earthquake followed by aftershocks of 4.8, 4.8 and 4.1 within an hour later. As you can see from the map below, seismicity since 1990 has made this a very active area.
In the area of Guacalito de Upala, more than 90 aftershocks (all under 1 on the Richter scale) have been felt, some 25 houses suffering damages, as well as 3 bridges and several roads.
In one point, the earth literally opened up, instilling fear and panic in the residents of the area.
The peculiar thing about this quake is that a river went missing.
Apparently in the moments following the earthquake, a community stood watch as their river disappeared in to the Earth. As of this writing it is still unknown exactly which community this occurred…. The affected citizens were interviewed and expressed concern for the loss of this substantial water supply to the area. Not only will this affect humans but also the livestock raised in the area.
