When quakes and aftershocks occurred

When aftershock knowledge is on the market, the corresponding maps and charts embody earthquakes inside 100 miles and 7 days of the preliminary quake. All occasions above are Japan time. Shake knowledge is as of Monday, April 20 at 5:11 p.m. Japan time. Aftershocks knowledge is as of Monday, April 20 at 10:38 p.m. Japan time.
