Quakes and aftershocks inside 100 miles
Aftershocks can happen days, weeks and even years after the primary earthquake. These occasions could be of equal or bigger magnitude to the preliminary earthquake, and so they can proceed to have an effect on already broken areas.
When quakes and aftershocks occurred
Supply: United States Geological Survey | Notes: Shaking classes are based mostly on the Modified Mercalli Depth scale. When aftershock knowledge is on the market, the corresponding maps and charts embrace earthquakes inside 100 miles and 7 days of the preliminary quake. All occasions above are Japanese. Shake knowledge is as of Friday, Oct. 10 at 4:47 p.m. Japanese. Aftershocks knowledge is as of Saturday, Oct. 11 at 1:14 p.m. Japanese.
