The USGS Earthquake Hazards Program is part of the National Earthquake Hazards Reduction Program (NEHRP), established by Congress in 1977. We monitor and report earthquakes, assess earthquake impacts and hazards, and research the causes and effects of earthquake. Featured Items 20th Anniversary of the M6.7 Northridge, CA Earthquake 2014 is the twentieth anniversary of the M6.7 January 17, 1994 Northridge, CA earthquake (4:31am local time) that resulted in 57 deaths, thousands injured, and over $20 billion in direct damage.Northridge: 20 Years Later The 1994 Northridge Earthquake: Impacts, Outcomes, and Next Steps View Application Induced Earthquakes Since 2001, the number of earthquakes has increased in parts of the US where earthquakes are rare. Many of these earthquakes have been tied to the long-term injection of wastewater in deep disposal wells.

Tree of Life Web Project

The Tree of Life Web Project (ToL) is a collaborative effort of biologists and nature enthusiasts from around the world. On more than 10,000 World Wide Web pages, the project provides information about biodiversity, the characteristics of different groups of organisms, and their evolutionary history (phylogeny). Each page contains information about a particular group, e.g., salamanders, segmented worms, phlox flowers, tyrannosaurs, euglenids, Heliconius butterflies, club fungi, or the vampire squid. ToL pages are linked one to another hierarchically, in the form of the evolutionary tree of life. Starting with the root of all Life on Earth and moving out along diverging branches to individual species, the structure of the ToL project thus illustrates the genetic connections between all living things.
