Fullerton faculty-student at California State University found the evidence of sudden sinking of the wetlands at the National Wildlife Refuge Seal Beach, California. It is caused by ancient earthquakes that shook the area at least three times in the past 2,000 years. Researchers believes that it could happen again.
The 500- acre wetlands located within the Naval Weapons Station Seal Beach are susceptible to rapid lowering in elevation during large 7.0 magnitude-earthquakes.
Talking about the new study CSUF professor of geological sciences, Matthew E. Kirby said
“Imagine a large earthquake—and it can happen again—causing the Seal Beach wetlands to sink abruptly by up to three feet. This would be significant, especially since the area already is at sea level,”
The study “Evidence for Coseismic Subsidence Events in a Southern California Coastal Saltmarsh,” is published in Scientific Reports, an open-access, peer-reviewed Nature research journal.
Located off Pacific Coast Highway between Belmont Shores and Sunset Beach, the Seal Beach wetlands likely formed due to complex, lateral movement of the Newport-Inglewood fault, said Leeper,a doctoral student in the earth sciences program at University of California, Riverside, is the lead author of the paper. The wetlands straddle a segment of the fault system, which extends from Beverly Hills in the north to the San Diego region in the south.
