that detects earthquakes as soon as they begin<\/a> and feeds the popular MyShake app.<\/p>\n\u201cMyShake absolutely worked for this event and it alerted a large number of people in a short amount of time,\u201d said Suresh Raman, manager of the MyShake app at the UC Berkeley Seismology Lab. Mr. Raman said that an estimated 650,000 people received the alert.<\/p>\n
Preliminary findings indicated that 99 percent of the people who received the alert got it before they felt shaking, if they felt the quake at all. Mr. Raman said that those in San Francisco got an estimated 35-second warning.<\/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

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
