3.0 quake 29 Jan 6:30 am (GMT -10)
A magnitude 3.0 earthquake near Hawaiian Ocean View, Hawaii County, Hawaii, USA, was reported only 9 minutes ago by the United States Geological Survey (USGS), considered the key international and national agency that monitors seismic activity in the US. The earthquake occurred at a very shallow depth of 4.2 miles beneath the epicenter early morning on Friday 29 January 2021 at 6:30 am 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 3.0 as well.
Towns or cities near the epicenter where the quake might have been felt as very weak shaking include Hawaiian Ocean View (pop. 4,400) located 12 miles from the epicenter, and Honaunau-Napoopoo (pop. 2,600) 16 miles away. In Captain Cook (pop. 3,400, 20 miles away), Kealakekua (pop. 2,000, 21 miles away), and Honalo (pop. 2,400, 23 miles away), the quake was probably not felt.
