I felt that one. I’ll give it a III-IV on the Modified Mercalli Intensity Scale. My refrigerator would concur. Here are the preliminary technical details from the United States Geological Survey. Sheesh. Hurricanes. Earthquakes. The End is Nigh!

Here is an interesting video of the Honshu Tsunami generated by an earthquake off the coast of the island of Japan on March 11, 2011. The video size makes it difficult to differentiate details:
Propagation of the March 11, 2011 Honshu tsunami was computed with the NOAA forecast method using MOST model with the tsunami source inferred from DART® data. From the NOAA Center for Tsunami Research, located at NOAA PMEL in Seattle, WA. See http://nctr.pmel.noaa.gov/honshu20110311
Want to go for a walk? I went on a walking tour of Charleston, South Carolina last week while there for a geology conference. Many of you know that Charleston was the unfortunate victim of a rather large earthquake back in the late 1800s. Led by Dr. Briget Doyle’s fill-in of the Geology Department from the College of Charleston, we walked around the southeastern portion of the Charleston Peninsula for an overview of the earthquake and an account of the structural damage recorded in the repair work still visible today.
I will say that I did not get a lot of one-on-one time with Dr. Doyle’s substitute guide. He was busy. The whole conference seemed to have an aura of “busy” about it. Or, maybe it was “running late”? I’m not sure. There was definitely the sense of a shortage of time the whole week with just about everyone. Regardless, I thought of you, my beloved readers and guests, and obtained enough digital photographs to fill about 3 DVDs. Not that I’m going to show that many here! More that there are plenty to choose from. So let’s go for a walk around town and I’ll try to do this . . . → Read More: Charleston Earthquake Photo Tour
Two weeks ago in Italy, the L’Aquila Prosecutor’s office indicted scientists, some of them members of the “Commissione Grandi Rischi” (Commission for High Risks), and civil protection officials for manslaughter. The basis for the indictment is that these people did not provide a short-term alarm to the population after a meeting of the Commission held in L’Aquila six days before the Mw 6.3 earthquake that struck that city and the surrounding area.
The allegations against the scientists are completely unfounded. Years of research worldwide have shown that there is currently no scientifically accepted method for short-term earthquake prediction that can reliably be used by Civil Protection authorities for rapid and effective emergency actions.
The international seismological community has long recognized that the best approach to defending populations from catastrophic earthquakes is not through earthquake prediction, but through risk mitigation and the application of appropriate safety measures to prevent buildings from collapsing. In this regard, the development of seismic hazard maps, which provide estimates of the probability of occurrence of predefined values of peak ground motion in a given time period, provide the specifications required by building codes to avoid collapse of buildings and the resulting fatalities
