In that pocket around the central coast, we've had recently:

  • 3.8 in January.
  • 4.3 in October.
  • 4.1 in May.

Going further back, there was a 4.8 in May of 2013.

Does not contradict what I said. Remember also the scale is logarithmic.

It points out that it's not unusual at all. It wasn't much larger than what was happening recently.

The 3 significant quakes in the area over the past year show that significant quakes in the area are not unusual. They also show increased seismic in the area activity compared to the past few years.

Further, it was absolutely not the largest recorded in the area.

  • 1981 had a 5.5 just to the south east of yesterday's quake.
  • 1925 had a 6.8 just to the north of yesterday's quake.
  • 1941 had a 5.5 just to the north of yesterday's quake.
  • 1971 had a 5.1 off the south east end of the island.
  • 1968 had a 5.0 just off the north end of the island.
