3.4 quake 29 Mar 3:38 am (GMT -7)
The United States Geological Survey reported a magnitude 3.4 quake in the United States near Tonopah, Nye County, Nevada, only 28 minutes ago. The earthquake hit early morning on Monday 29 March 2021 at 3:38 am local time at a very shallow depth of 4.2 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 3.4 earthquake as well.
Towns or cities near the epicenter where the quake might have been felt as very weak shaking include Mina (pop. 160) located 21 miles from the epicenter. In Tonopah (pop. 2,500, 41 miles away), and Hawthorne (pop. 3,300, 45 miles away), the quake was probably not felt.

/ Light shaking (MMI IV) / rattling, vibrating / 5-10 s : I fell the ground constantly shaking, and sometimes i have to stop completely what i am doing until it goes away.
