Scientists Measure Gravity Change From Earthquake

Posted by ryuzaki0 on from the seismic-remodeling dept.

Science Daily is reporting that scientists were able to use satellite data to watch changes in the Earth's surface caused by a massive earthquake. These changes had two major measurable effects on the region. The massive uplift in the seafloor changed GPS measurements, and the density of the rock beneath the seafloor changed which produced a detectable change in gravity.

    I thought I felt lighter this morning...

  2. So, how much is it now? by lheal · · Score: 5, Funny

    I have a lot to keep track of, what with my checkbook, blogs, email, vehicle oil changes and tire rotation, bills, and keeping various client networks running.

    So I'd appreciate it if someone could keep track of this whole gravity situation, and just give me a summary. Let me know if we're all about to go floating off into LEO, but otherwise, keep the announcements to a minimum.

    Detecting "major" quakes - those measuring a magnitude of 7 to 8.9 - which occur frequently is being investigated. NASA's planned extension of the current mission, dubbed GRACE 2, and its enhanced instrumentation should aid in that effort.

    However, Han is hopeful that NASA's planned expansion of the current mission, dubbed GRACE 2, and its enhanced instrumentation, might allow the detection of "major" quakes - those measuring a magnitude 7 to 8.9 - which occur frequently.

    Let's hope this is the final nail in the coffin for the theory of 'intelligent falling' proposed as an alternative to gravity.

    If half the earth moves relative to the other half, I'd think we'd have bigger problems.

    |Or more interesting dose anyone have a map of the earth and differences in gravity in different areas? (I smell a new google map)"

    And all the fat people can move to neighborhoods with lower gravity, Voila! Instant weight loss.
