The National Earthquake Information Center says there are about 55 earthquakes a day around the world — that's 20,000 a year. Fortunately, most are too weak to cause damage, but stronger quakes, depending on location and other factors, can cause casualties, injuries, and property damage.
The Southern California Earthquake Center is working with the team to have the educational pages reviewed by educators to meet current curriculum guidelines of the state of California. At this time, there are about 50 GPS receivers in place around Southern California with new sites being added every week.
The GPS earthquake research is funded by NASA's Office of Mission to Planet Earth, the United States Geological Survey and the Southern California Earthquake Center (SCEC), a National Science Foundation Science and Technology Center headquartered at the University of Southern California.
For instance, if a large earthquake struck San Francisco, liquefaction — where loosely packed or waterlogged sediment loses its stability after severe ground shaking — could pose a problem for dams and levees along the Sacramento-San Joaquin River Delta. “There’s over a thousand miles of levees,” said Jones.
The mission is a cooperative project between the National Aeronautics and Space Administration (NASA), the National Imagery and Mapping Agency (NIMA) of the U.S. Department of Defense (DoD), and the German and Italian space agencies. It is managed by NASA's Jet Propulsion Laboratory, Pasadena, CA, for NASA's Earth Science Enterprise, Washington ...
The Ridgecrest Earthquake Sequence began with a magnitude 6.4 foreshock on July 4, 2019, followed by a magnitude 7.1 mainshock the next day with more than 100,000 aftershocks. The sequence rattled most of Southern California, but the strongest shaking occurred about 120 miles (190 kilometers) north of Los Angeles near the town of Ridgecrest.
The National Hurricane Center predicted the eye of Ivan will make landfall across Mobile Bay in Alabama late Wednesday or early Thursday. These images of Hurricane Ivan were acquired by the AIRS infrared, microwave, and visible sensors on September 15 at 1:30 pm local time as the storm moves in to Alabama.
NASA's Jet Propulsion Laboratory, the leading center for robotic exploration of the solar system. JavaScript is required NASA's ARIA team used InSAR analysis of data from the ALOS-2 satellite to map how much and in what direction the ground moved following two strong Southern California earthquakes on July 4 and July 5, 2019.
The new research network builds on decades of technology development supported by the National Science Foundation, the Department of Defense, NASA and the U.S. Geological Survey (USGS). The network uses real-time GPS measurements from nearly 500 stations throughout California, Oregon and Washington.
It was the strongest earthquake to occur in that vicinity since a magnitude 8.0 quake there in 1934 that caused more than 10,000 fatalities. To assist in the disaster response efforts, scientists at NASA's Jet Propulsion Laboratory, Pasadena, California, and California Institute of Technology in Pasadena, in collaboration with the Italian Space ...
