Hundreds of earthquakes struck the Brawley area of Imperial County, California, from May 9 to 11, 2026, including the strongest reported M4.7 event at 07:10 UTC on May 10. The swarm caused infrastructure damage, including water line breaks and road damage.
The Salton Sea in California has been shrinking steadily since 2003, leading to a rise in toxic hydrogen sulfide gas emissions. A recent study found that these emissions frequently exceed safety limits, especially in communities along the lake’s shoreline, putting residents’ health at increasing risk.
The Salton Sea, California’s largest inland lake, is receding faster than anticipated, primarily due to water diversions from the Colorado River to urban areas like San Diego. A recent study led by Ryan Sinclair of Loma Linda University, involving community scientists and balloon mapping techniques, has documented shoreline changes, revealing that toxic dust levels could further deteriorate air quality for nearby residents.
