• Quake, rattle & roll

    by  • 12 January, 2008 • General • 5 Comments

    So we had this relatively major quake with its epicenter in Leonidio measuring 6.2 last Sunday. To be precise at 37.16N and 22.64E, at a depth of 72km. A whole controversy broke out in the days thereafter about the role and functioning of the Greek seismographic services. What is strange to me is that since then, nobody mentioned the following earthquake registrations (times are in UTC):

    2008-01-06 05:14:18.4 37.16N 22.64E depth 72km Mw 6.2 Initial quake
    2008-01-08 23:23:06.3 37.15N 22.74E depth 74km ML 3.3
    2008-01-11 12:56:22.4 37.18N 22.63E depth 97km ML 4.6
    2008-01-11 17:59:19.8 37.14N 22.73E depth 91km ML 3.3

    They are all in the same area, admittedly with a much lower magnitude, but isn’t that alarming, this seismic activity in the same spot over a short period of time?

      Hello Luc,
      This is not my field, but aren’t there supposed to be “after shocks” after every earth quake? Something like the tectonic plates searching for their new position?

      Peter, nice to drop by again. Yes aftershocks are normal, everybody assured me, but I’m wondering if 5 days later we are technically still talking about aftershocks, or if this is an indication of continued or renewed seismic activity, foreboding similar magnitude or bigger shocks.

      I kept telling people there were quakes on the 11th, everyone thought I was drunk or something at lunch. Aftershocks are normal, says this California girl :)

      Kat, where on earth do you find the time to come and visit these ramblings of mine? What with your own and very thorough articles, your extensive research for each of them, do you sleep at all? Nice to read you had a good time in Spain and welcome back.

      The short answer is that you make time to do things that are important to you. The longer answer is I like you and your writing, in addition to the new look of the site, and I only sleep about 6-7 hours a day.
