What on earth

GPS and disaster-prediction

Monday, December 19, 2005 8:46:22 PM

So far seismometers have been about the only means of detecting earthquakes and measuring their force. The analyses of seismic waves takes a lot of computing and precious time and rapid determination of earthquake magnitude from seismic data alone is problematic for the largest events. Part of the work could be done faster by GPS. Using a combination of seismic and GPS data could save thousands of lives. GPS receivers can gauge the ground movements created by tsunami-causing earthquakes with unprecedented precision and speed.

GPS Could Speed Tsunami Warnings and in addition GPS modules could be used to monitor the activity of volcanoes and landslides in real time. Findings in this direction were presented at the American Geophysical Union conference in San Francisco 5–9 December 2005 (a conference I have mentioned a couple of times earlier).

Abstract

Epicentre and hypocentre. The hypocentre, more often called the focus, is the actual point where the earthquake starts (more or less deep underground), while the epicentre is the point on the earth's surface directly above the focus of the earthquake.

I like the idea of the EU putting up Galileo , and noticed the Americans decided to work with , not against them in the GPS field ..... R/KF

Yes, that's nice, isn't it. Obviously Galileo opens extraordinary possibilities.

  • Siberian Earthquake May Set a New Record

    Today's magnitude-8.3 earthquake beneath the Kamchatka Peninsula was both extraordinarily deep and extraordinarily large. At 610 kilometers depth, it was pretty much as deep as earthquakes get. That's down near the bottom of the upper mantle. And at M8.3, it was one of the largest deep earthquak ...

  • GSA Fresno: One More Day

    Wednesday was the last day of the formal sessions at the GSA Cordilleran Section meeting. The talks I attended were the final segment of the "meeting in a meeting" and centered on the hot new tool for sorting out the history of the highly scrambled western margin of North America: detrital zirco ...

  • Monday and Tuesday at GSA Fresno

    The heart of the GSA Cordilleran Section meeting is over; the Wednesday session will be just half a day, giving me time for a side trip or two before the post-meeting field trip. It has been fun hearing from and talking with some of our local West Coast experts and the visiting experts who have ...

  • A Close Look at the Irvingtonian

    I'm spending most of the week in Fresno, California, at the Cordilleran Section meeting of the Geological Society of America. Yesterday, in one of the preliminary field trips for the event, I joined a party of 25 to visit the fossil collection from the Fairmead Landfill project a few miles north ...

  • This Week's Geo-Quiz: Geologic Maps

    If you think you know your way around, think again. A geologic map will transform the way you see your stomping grounds. The familiar features—roads, cities, buildings and all that—are grayed out while the aboriginal land itself shines forth in colors, patterns and lines. Sprinkling ...

  • Planetary Defense Conference 2013 Part 1

    First part of a 3 part wrap up to April's Planetary Defense Conference: a very brief review of the status of research in asteroid threat related fields based on the conference, report on special activities at the conference, and links to video and audio related to the conference.

    NOAA forecasts an above-normal and possibly very active Atlantic hurricane season in 2013, in their May 23 outlook. They give a 70% chance of an above-normal season, a 25% chance of an near-normal season, and 5% chance of a below-normal season. They predict a 70% chance that there will be 13 - 2 ...

    The SCIMPI tool has nine different sensors staged to record temperature (three will also record pressure) at different depths that straddle what is called the BSR (a topic for a separate post, but think gas hydrates). read more

    A new report from the USGS warns that on the high demand basis for nuclear power through 2035, the identified resources from operating and developing mines is inadequate. In the report, Critical Analysis of World Uranium Resources, they found that "This analysis indicates that mine develo ...

  • Yemeni oil pipeline blown up by unknown bombers.

    A section of Yemen's main oil pipeline, carrying crude from the Safer Oil Field to the Port of Hodeida, on the Red Sea, was blown up in the the Sarwaj District of Marib Province early in the morning of Friday 24 May 2013, halting the flow of oil from the country. It is unclear who was respon ...
