3.4 quake 10 Mar 3:47 pm (GMT -7)
3.4 quake 10 Mar 3:47 pm (GMT -7)
An earthquake of magnitude 3.4 occurred early afternoon on Wednesday 10 March 2021 at 3:47 pm local time near Stanley, Custer County, Idaho, USA, as reported by the United States Geological Survey.
According to preliminary data, the quake was located at a very shallow depth of 5.3 miles. Shallow earthquakes are felt more strongly than deeper ones as they are closer to the surface. Magnitude and other quake parameters can still change in the coming hours as the agency continues to process seismic data.
Our monitoring service identified a second report from the European-Mediterranean Seismological Centre (EMSC) which listed the quake at magnitude 3.4 as well.
Towns or cities near the epicenter where the quake might have been felt as very weak shaking include Stanley (pop. 68) located 20 miles from the epicenter. In Challis (pop. 1000, 48 miles away), the quake was probably not felt.

We truly love working to bring you the latest volcano and earthquake data from around the world. Maintaining our website and our free apps does require, however, considerable time and resources.
We need financing to increase hard- and software capacity as well as support our editor team. We're aiming to achieve uninterrupted service wherever an earthquake or volcano eruption unfolds, and your donations can make it happen! Every donation will be highly appreciated. If you find the information useful and would like to support our team in integrating further features, write great content, and in upgrading our soft- and hardware, please make a donation (PayPal or Online credit card payment).

Planned features:
  • Improved multilanguage support
  • Tsunami alerts
  • Faster responsiveness
Thanks to your past donations, these features have been added recently:
  • Design upgrade
  • Detailed quake stats
  • Additional seismic data sources
