Small magnitude 3.1 quake hits 41 miles southwest of Hilo, Hawaii, United States early evening
3.1 quake 16 Apr 7:46 pm (GMT -10)
3.1 quake 16 Apr 7:46 pm (GMT -10)
A magnitude 3.1 earthquake near Hilo, Hawaii County, Hawaii, USA, was reported only 8 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 very shallow depth of 1.9 miles beneath the epicenter early evening on Friday 16 April 2021 at 7:46 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.
Our monitoring service identified a second report from the European-Mediterranean Seismological Centre (EMSC) which listed the quake at magnitude 3.1 as well.
Towns or cities near the epicenter where the quake might have been felt as very weak shaking include Honaunau-Napoopoo (pop. 2,600) located 14 miles from the epicenter, Captain Cook (pop. 3,400) 18 miles away, Kealakekua (pop. 2,000) 18 miles away, and Honalo (pop. 2,400) 19 miles away. In Pāhala (pop. 1,400, 21 miles away), Holualoa (pop. 8,500, 22 miles away), Kalaoa (pop. 9,600, 28 miles away), and Hilo (pop. 43,300, 41 miles away), the quake was probably not felt.
