Note: Map shows the area with a shake intensity of 4 or greater, which U.S.G.S. defines as \u201clight,\u201d though the earthquake may be felt outside the areas shown. \u00a0All times on the map are Eastern. The New York Times <\/p>\n
A major, 7.4-magnitude earthquake struck off the northeast coast of Japan on Monday, according to the United States Geological Survey.<\/p>\n
The temblor happened at 3:53 a.m. Eastern about 62 miles northeast of Miyako, Japan, data from the agency shows.<\/p>\n
As seismologists review available data, they may revise the earthquake\u2019s reported magnitude. Additional information collected about the earthquake may also prompt U.S.G.S. scientists to update the shake-severity map.<\/p>\n
Aftershocks detected <\/p>\n
Subsequent quakes have been reported in the same area. Such temblors are typically aftershocks caused by minor adjustments along the portion of a fault that slipped at the time of the initial earthquake.<\/p>\n
Quakes and aftershocks within 100 miles <\/p>\n
Aftershocks can occur days, weeks or even years after the first earthquake. These events can be of equal or larger magnitude to the initial earthquake, and they can continue to affect already damaged locations.<\/p>\n
