For a small indication of what the people in Japan have been enduring, take a gander at this chart of global seismic activity from the U.S. Geological Service. You can find the 9.0 quake that rocked the nation on March 11 at 05:46.
Fear and Trembling
The latest from america
At the Vatican on Saturday, Pope Leo urged “reason and responsibility” amid rising tensions between Israel and Iran—just hours before lighting up the jumbotron at Chicago’s Rate Field, calling 30,000 faithful to be “beacons of hope.”
As I write, Mr. Trump is declaring that “nobody knows” what he is going to do about Iran. I fear that “nobody” includes him.
A Homily for the Feast of Corpus Christi, by Father Terrance Klein
”Catholics across the ideological spectrum have expressed hope that Leo will be able to heal some of the divisions that emerged during the pontificate of his predecessor, Pope Francis.”
And from the list on the linked page there seems to be a constant movement of the plates in the area of the original quake and a couple dozen or more of 6.0 quakes which were the size of the Christchurch quake since the 9.0 quake off the coast of Honshu. My guess is that we will learn a lot more about the effects of earthquakes and the potential damage depending upon the distance from the epi-center.
