Earth is fighting to stay alive. Mass dieoffs, triggered by anthropogenic assault and fallout of planetary defense systems offsetting the impact, could begin anytime!

Magnitude 4.0 quake hits Utah near gas fields

Posted by feww on June 4, 2009

Utah quake gas drilling related, too?

Magnitude 4.0 earthquake struck Utah close to two of the state’s gas fields

A magnitude 4.0 earthquake struck northwest of Utah’s Box Elder County, close to Hogback Ridge field and Rozel Point field at a shallow depth of about 7.5 km (4.7 miles) June 3, 2009. See below for depth uncertainty margin and other details.

The discovery of new wells in the Box Elder County was previously described as “Two Remote Wildcats.”

FEWW moderators believe the Utah earthquake detailed here, and the following quakes listed below may have been related to gas-drilling activities in the West South and Mountain regions.

  1. Magnitude 4.2  – Western Montana [March 6, 2009]
  2. M 3.5  –  Wyoming [March 7, 2009]
  3. M 3.0  –  Colorado, 2009 [March 22, 2009]
  4. M 3.3  –  Northern Texas [May 16, 2009]
