These faults are considered “active” and are likely to cause another earthquake.Īll data in this project comes from the U.S. 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. see the locations of Volcanic Eruptions. Features: - see all recent earthquakes on a 3D earth globe. An intensity VII quake is widely felt and can destroy poorly built structures. Earthquakes Multiple sources (EMSC & USGS) - Volcanic Eruptions around the world. Magnitude: 0.1 to 1.0 1.0 to 2.0 2.0 to 3.0 3.0 to 4.0 4.0 to 5.0 5.0 to 6.0 6. The measure is designated using Roman numerals.Ī quake at intensity III can be felt near the epicenter, but with no damage to structures. (KGO) - A 3.1-magnitude earthquake was reported near Castro Valley, according to the U.S. Rather than a gauge of pure shaking, intensity takes into account the effects on people and damage to infrastructure. The two sliders control the Magnitude and Age of Earthquake flags. The control panel shown on the left side of the window configures how the Earth and Earthquakes are shown.

Intensity contours show how strongly a quake was felt and are displayed on the Quake Tracker when available. Download the Free Edition of Earthquake 3D for Windows at CNET. 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 anywhere in the world.
