Caracas
The main body of water in Caracas is the Guaire River, which flows across the city and empties into the Tuy River, which is also fed by the El Valle and San Pedro rivers, in addition to numerous streams which descend from El Ávila. The La Mariposa and  reservoirs provide water to the city. The city is occasionally subject to earthquakes – notably in 1641 and 1967.
