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. NASA's Integrated Multi-satellitE Retrievals for GPM (IMERG) were used to estimate the total

Tropical Storm Fernand Causes Deadly Mudslides

Heavy rain with tropical storm Fernand generated mudslides that caused the reported deaths of 13 people in the Mexican state of Veracruz. TRMM precipitation data are used to calibrate rainfall estimates from other satellites. The resulting TRMM- based, near-real time Multi-satellite Precipitation Analysis (TMPA) at the NASA Goddard Space Flight Center is used to estimate rainfall over a wide portion of the globe. The analysis above shows estimated TMPA rainfall totals for the period from August 20-27, 2013 when Fernand was developing and moving through the area. Total Rainfall greater than

2010 Landslide in Gansu, China

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.

Dominican Republic And Haiti Hit By Deadly Floods

It has been reported that spring floods with mudslides have resulted in the death of at least 9 people and forced 11,000 people to flee their homes in the Dominican Republic. Data from the TRMM satellite are used to calibrate rainfall data merged from various satellite sources. TRMM-based, near-real time Multi-satellite Precipitation Analyses (TMPA) at the NASA Goddard Space Flight Center are used to monitor rainfall over the global Tropics. TMPA rainfall estimates are shown above for the week from April 19 to April 26, 2012. This analysis shows that extreme rainfall (shown in dark red)
