NASA reports Crowdsourced Smartphone Data could give advance notice for People in Earthquake Zones

NASA - National Aeronautics and Space AdministrationPasadena, CA – Smartphones and other personal electronic devices could, in regions where they are in widespread use, function as early warning systems for large earthquakes, according to newly reported research.

This technology could serve regions of the world that cannot afford higher quality, but more expensive, conventional earthquake early warning systems, or could contribute to those systems.

The study, led by scientists at the U.S. Geological Survey (USGS), found that the sensors in smartphones and similar devices could be used to build earthquake warning systems.

Cell phones can detect ground motion and warn others before strong shaking arrives. ("Everyone Check Your Phones - NYC" by Jim Pennucci, used under CC BY.)

NASA’s Mars Reconnaissance Orbiter images reveals new map showing ancient lakes and quakes on Mars

NASA - National Aeronautics and Space AdministrationPasadena, CA – Long ago, in the largest canyon system in our solar system, vibrations from “marsquakes” shook soft sediments that had accumulated in Martian lakes.

The shaken sediments formed features that now appear as a series of low hills apparent in a geological map based on NASA images. The map was released today by the U.S. Geological Survey (USGS).

Details of hilly terrain within a large Martian canyon are shown on a geological map based on observations from NASA's Mars Reconnaissance Orbiter and produced by the U.S. Geological Survey. Notations are explained in the legend with the full map, at http://pubs.usgs.gov/sim/3309/. (NASA/JPL-Caltech/Univ. of Arizona/USGS)

What if a Meteorite Struck the United States?

 

Written by Hannah Hamilton and David Powars

U.S. Geological SurveyReston, VA – What if the February 15th, 2013 meteor strike hit the United States, and not Russia?

What if it were the size of the meteorite that struck off the coast of Virginia during the age when modern mammals began to appear?

What if . . .

Landsat 5 Mission in Jeopardy

 

The U.S. Geological Survey (USGS) has stopped acquiring images from the 27-year-old Landsat 5 Earth observation satellite due to a rapidly degrading electronic component.

Landsat 5 was launched in 1984 and designed to last 3 years. The USGS assumed operation of Landsat 5 in 2001 and managed to bring the aging satellite back from the brink of total failure on several occasions following the malfunction of key subsystems. There is now an increasing likelihood that the Landsat 5 mission is nearing its end.

Quake hits Illinois, disturbing vibrations reach south to Clarksville

 

The USGS equipment maps earthquake hazard zones on the spot.No, you’re not going crazy. There was an earthquake felt in middle Tennessee during the wee hours of the morning. An earthquake hit the Midwest today, originating 135 miles southeast of Springfield, Illinois, and merely 38 miles from Evansville, IN. At magnitude 5.4, the epicenter of the quake was 6 miles from West Salem, IL.

I was watching StarGate SG-1 when the floor shook. And it wasn’t the surround sound. I stood up as vibrations rattled the front door of the house, coming from that direction. The cats all freaked out and stared in the same unnerving direction I was staring in.

The vibrations grew, and the tremors then dissipated. By coincidence, I heard sirens going off down the road not long afterwards as I listened to the news, and checked online for any reports. Early reports to the United States Geological Survey spilled in from the IL/IN area. «Read the rest of this article»
