Small 3.3 quake hits near Hilo, Hawaii County, Hawaii, USA
3.3 quake 13 Feb 1:28 pm (GMT -10)
3.3 quake 13 Feb 1:28 pm (GMT -10)
A magnitude 3.3 earthquake near Hilo, Hawaii County, Hawaii, USA, was reported only 7 minutes ago by the United States Geological Survey, considered the key international and national agency that monitors seismic activity in the US. The earthquake occurred at a moderately shallow depth of 19 miles beneath the epicenter around noon on Saturday 13 February 2021 at 1:28 pm local time. 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.
A second report was later issued by the European-Mediterranean Seismological Centre (EMSC), which listed it as a magnitude 3.3 earthquake as well.
Towns or cities near the epicenter where the quake might have been felt as very weak shaking include Pāhala (pop. 1,400) located 2 miles from the epicenter. In Hawaiian Ocean View (pop. 4,400, 20 miles away), Volcano Village (pop. 2,600, 25 miles away), Mountain View (pop. 3,900, 36 miles away), Holualoa (pop. 8,500, 44 miles away), Hawaiian Paradise Park (pop. 11,400, 44 miles away), and Hilo (pop. 43,300, 46 miles away), the quake was probably not felt.
