The 2008 Reno earthquakes, also known as the Mogul-Somersett earthquake sequence, occurred in and near the western Reno, Nevada, suburbs of Mogul and Somersett. The earthquake swarm began in February 2008, but the first significant quake of the series occurred on April 15, 2008, registering a 3.6 magnitude. On April 24, 2008, two quakes in the same area registered 4.1 and 4.2. On April 25, 2008, the largest earthquake occurred, registering at magnitude 4.9 and causing damage in the immediate area around the epicenter, including destroying 200 feet (61 m) of a wooden flume supplying water from the Highland Ditch, also known as the Highland Ditch flume. The flume carried up to 50 million US gallons (190,000 m3) a day from the Highland Ditch to Reno's Chalk Bluff Water Treatment Facility and another 5 million US gallons (19,000 m3) to area irrigation users.
