seen a swarm of noticeable earthquakes recently, which is uncommon. Two of those have occurred on the San Andreas: the 1906 earthquake that destroyed much of San Francisco and the 1857 quake that ruptured a length of the fault from Monterey County. PT, was in the Pacific about 15 miles from Fortuna, a city of about 12,000 people in Humboldt County, part of California’s forested Redwood. ![]() The ARIA team’s analysis was funded by NASA’s Disasters Program. GUIDE:The Big One: Are you prepared for a large earthquake in California. The epicenter of the quake, which struck at 2:34 a.m. The Japanese Aerospace Exploration Agency (JAXA) provided the ALOS-2 data for the production of the map. NASA’s Disasters Program promotes the use of satellite observations in predicting, preparing for, responding to and recovering from disasters around the world. NASA analysts are using data from satellites to produce visualizations of land deformation and potential landslides, among other earthquake impacts, and are making them available to response agencies. The image featured on the cover of Nature and. In the aftermath of the earthquakes, NASA’s Earth Science Disasters Program is in communication with the California Earthquake Clearinghouse, which is coordinating response efforts with the California Air National Guard, the USGS and the Federal Emergency Management Agency. The first practical demonstration was in 1992, when the ERS-1 satellite captured surface deformation caused by the Landers, California earthquake 1. State and federal scientists, including those from the California Geological Survey and USGS, are using this surface deformation map in the field for assessing the damages and mapping the faults that broke during the two major earthquakes as well as the thousands of aftershocks. The USGS reported over 1,000 aftershocks in the region following the July 5 earthquake. The linear features that cut the color fringes in the southeast indicate likely locations of surface rupture caused by the earthquakes, and the “noisy” areas in the northwest may indicate locations where the ground surface was disturbed by them. The post-quake imagery was acquired on July 8, 2019, and compared with April 8, 2018, data from the same region.Įach color cycle represents 4.8 inches (12 centimeters) of ground displacement either toward or away from the satellite. The Advanced Rapid Imaging and Analysis (ARIA) team at NASA’s Jet Propulsion Laboratory in Pasadena, California, used synthetic aperture radar (SAR) data from the ALOS-2 satellite to produce a map showing surface displacement from the earthquakes. Click on an earthquake on the above map for a zoomed-in view. Geological Survey, the 7.1 quake was one of the largest to hit the region in some 40 years. Recent Earthquakes in California and Nevada. ![]() The epicenter of the quakes was near the city of Ridgecrest, about 150 miles (241 kilometers) northeast of Los Angeles. California quakes left a crack in the Earth so big it can be seen from space N'dea Yancey-Bragg USA TODAY 0:00 1:26 The two massive earthquakes that rocked Southern California last week. Damage from two strong earthquakes that rattled Southern California on July 4 and July 5 - a magnitude 6.4 and a magnitude 7.1, respectively - can be seen from space.
