The 1812 Caracas earthquake took place in Venezuela on March 26, 1812 (on Maundy Thursday) at 4:37 p.m. It measured 7.7 on the Richter magnitude scale. It caused extensive damage in Caracas, La Guaira, Barquisimeto, San Felipe, and Mérida. An estimated 15,000-20,000 people perished as a result, in addition to incalculable material damage. The seismic movement was so drastic that in a zone named Valecillo a new lake was formed and the river Yurubí was dammed up. Numerous rivulets changed their course in the valley of Caracas, which was flooded with dirty water.
