We’ve just had our third small earthquake in the past month. This one was a number 4 on the Japanese shindo scale that measures seismic intensity from 0 – 7. I’m not sure if this makes it more or less likely that we will soon experience the oft-predicted 1 in 100 year Tokai earthquake. (The last great Tokai Earthquake was in 1854 so you can understand why people around here are a bit nervous about it.)
After each earthquake we turn on the TV to see where the epicentre was, the magnitude and depth, and most importantly whether or not a Tsunami is predicted to follow. This information is broadcast within minutes of the quake occurring thanks to Japan’s advanced network of hundreds of seismic intensity meters.
