New and intriguing information identified by the U.S. Geological Survey (USGS) and its partners has been published in the Journal of Geophysical Research.

The San Gabriel Valley rose almost 2 inches (47 mm) in less than four months, and the margins of the basin were pushed outward by almost half an inch (10 mm). The expansion was five times larger than slight oscillations observed since 1998.
