Mudslides & Flooding Produced By Extreme Rainfall Over Southern California

It is sunny in southern California today but recent unusually heavy rainfall led to rock slides, mudslides and flooding in that part of the country. Rainfall of almost 4 inches (101.6 mm) in one day was reported in Long Beach, California. Some highways in the area were flooded due to intense downpours. Rainfall since the fall of 2016 has improved drought conditions over northern California but Southern California has been slower to improve because of the exceptional rainfall deficit in that area.

Around midnight on August 8, 2010, a violent surge of loosened earth roared down mountain slopes and slammed into quietly sleeping neighborhoods in Zhouqu County in Gansu, China.

The catastrophic mudslides—the deadliest in decades according to state media—buried some areas under as much as 23 feet (7 meters) of suffocating sludge. 1,765 people died. Property damages totaled an estimated $759 million. Cutting from right to left, this detailed image, from DigitalGlobe’s WorldView-2 satellite, shows the largest slide in the lower part of the city on August 10, 2010.
