Magnitude 6.5 Japan Earthquake
We have only been here in Kyoto and Sendai, Japan, 10 days and so far have experienced a super typhoon (Neoguri) and now an earthquake. This morning, I went down to the 26th floor of our hotel here in Sendai, to photograph the rising sun. Just before 4:00 am, the building started moderate shaking, which continued for about 20 seconds. It turned out to be a magnitude 6.8 earthquake (later downgraded to a magnitude 6.5 event) in the trench. I am here to give a series of lectures at Tohoku University on earthquake forecasting, so it was timely. No damage or injuries, and no significant tsunami.
Below I show two screenshots from the hazard viewer centered on Sendai. The circular selection region is 100 miles (162 km) in diameter.
The probabilities in the tabel below were computed on July 11 at about 5:00 pm Pacific Time,that is, pre-earthquake. It will be interesting to see the changes when they are recomputed tonight at midnight.
Forecast timeseries are reproduced below for the selected region. On the left is the forecast for M>6, 1 year from now. On the right is the forecast for M>7, 1 year from now.
