Magnitude 4.3 earthquake strikes near Pāhala, Hawaii County, Hawaii, United States
The United States Geological Survey (USGS) reported a magnitude 4.3 quake in the United States near Pāhala, Hawaii County, Hawaii, only 9 minutes ago. The earthquake hit early evening on Thursday 14 January 2021 at 6:15 pm local time 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.
A second report was later issued by the European-Mediterranean Seismological Centre (EMSC), which listed it as a magnitude 4.3 earthquake as well.
Based on the preliminary seismic data, the quake should not have caused any significant damage, but was probably felt by many people as light vibration in the area of the epicenter.
Weak shaking might have been felt in Pāhala (pop. 1,400) located 5 miles from the epicenter, Naalehu (pop. 870) 16 miles away, Wai‘ōhinu (pop. 210) 17 miles away, and Volcano Village (pop. 2,600) 19 miles away.
Other 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 26 miles from the epicenter, Mountain View (pop. 3,900) 30 miles away, Hawaiian Paradise Park (pop. 11,400) 38 miles away, and Hilo (pop. 43,300) 40 miles away.

Data for the same earthquake reported by different agencies
Info: The more agencies report about the same quake and post similar data, the more confidence you can have in the data. It takes normally up to a few hours until earthquake parameters are calculated with near-optimum precision.
