It highlights earthquakes that have occurred in the past 30. Click on an arrow at edge or corner of above map to go to an adjacent map. Click on an earthquake on the above map for more information. These faults are considered “active” and are likely to cause another earthquake.Īll data in this project comes from the U.S. Our real-time Quake Tracker was developed in The Chronicles newsroom. Recent Earthquakes in California and Nevada. Our optional fault layer shows fault lines from the USGS that cross the Bay Area that have seen evidence of seismic activity in the last 150 years.

At intensity VIII and beyond, structural engineers help determine how to categorize the quake based on observable damage, which can include rails bent, bridges destroyed and buildings shifted off their foundations.
An intensity VII quake is widely felt and can destroy poorly built structures. Southern California has had: (M1.5 or greater) 5 earthquakes in the past 24 hours. The measure is designated using Roman numerals.Ī quake at intensity III can be felt near the epicenter, but with no damage to structures. Information available includes the age of the most recent activity on each fault segment, surface rupture areas, and whether or not the faults are visible at the surface. 34 km SSE of Goldfield, Nevada 00:07:56 (UTC-07:00) 14.1 km 2.5 15km E of Coso Junction, CA 22:07:34 (UTC-07:00) 1.9 km 2.5 52 km S of Silver Peak, Nevada 15:29:53 (UTC-07:00) 7.2 km 3.1 25km SW of Lone Pine, CA 20:00:52 (UTC-07:00) 2.5 km 2. Rather than a gauge of pure shaking, intensity takes into account the effects on people and damage to infrastructure. The California Geological Survey's interactive map allows users to identify the location and classification of faults throughout California. Intensity contours show how strongly a quake was felt and are displayed on the Quake Tracker when available. Use the map below to explore recent earthquake activity. Quakes below magnitude 3.0 are often not felt and do not appear on this map. The Quake Tracker displays quakes from the past 30 days with magnitudes above 3.0 in Northern California, 4.0 in Southern California, 5.0 in the United States, and 7.0 in North America.
