A moderately shallow magnitude 3.3 earthquake was reported after midnight near Hilo, Hawaii County, Hawaii, USA.
According to the United States Geological Survey, the quake hit on Wednesday 17 March 2021 at 12:25 am local time at a moderately shallow depth of 20 miles. The exact magnitude, epicenter, and depth of the quake might be revised within the next few hours or minutes as seismologists review data and refine their calculations, or as other agencies issue their report.
