The 1989 Loma Prieta earthquake ended decades of seismic tranquility in the San Francisco Bay region. It was considered then . as well as now . to be a wake-up call for the region to prepare for potentially even more devastating earthquakes. How well is the Bay Area prepared for the next large earthquake?

Nearly 15,000 acres of salt ponds in the southern San Francisco bay were purchased in 2003 for restoration by a partnership of Federal, State, and nonprofit organizations
This new USGS video product documents how science is playing a crucial role in restoring these wetland areas and shows that...

In May, 2006 hot, dark mud appeared from a fissure covering more than 10 square kilometers, displacing more than 30,000 people. The ongoing mud extrusion has also damaged or broken important transportation and communication infrastructure, displaced an oil pipeline, caused the closure of numerous factories, and impacted agricultural development.
The USGS was invited for a fact-finding visit to assess the ongoing geological, social, economic, and political issues associated with the mud extrusion.
Sea otter populations in the central and western Aleutian Islands have declined by 75-95% over the past 15-20 years, while populations in the nearby Russian Commander Islands have remained roughly stable. There are no obvious environmental explanations for these disparate patterns, as the archipelagos are physically and biologically quite similar. Because of the differing population trajectories and the role of sea otters as keystone predators, the two kelp forest ecosystems that were once very similar are now quite different. What has caused these differences?
The Parkfield earthquake of 1966 launched a torrent of research at the USGS in Menlo Park. With the San Andreas Fault as a backyard lab and global earthquakes as a guide, the USGS has changed the landscape of earthquake science in:
