An earthquake of magnitude 3.2 occurred in the afternoon on Saturday 20 February 2021 at 5:33 pm local time near Hilo, Hawaii County, Hawaii, USA, as reported by the United States Geological Survey.
According to preliminary data, the quake was located at a moderately shallow depth of 21 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.
Our monitoring service identified a second report from the European-Mediterranean Seismological Centre (EMSC) which listed the quake at magnitude 3.2 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 3 miles from the epicenter. In Hawaiian Ocean View (pop. 4,400, 21 miles away), Volcano Village (pop. 2,600, 23 miles away), Holualoa (pop. 8,500, 40 miles away), Hawaiian Paradise Park (pop. 11,400, 42 miles away), Hilo (pop. 43,300, 43 miles away), Kalaoa (pop. 9,600, 46 miles away), and Kalaoa (pop. 9,600, 46 miles away), the quake was probably not felt.
