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

Strong Earthquake Hits Utah

Posted by feww on April 16, 2010

Quake Measuring 5.1Mw Strike 8km ENE Randolph Utah

The quake was epicentered at 41.79°N,111.04°W and struck at a depth of about 1 km on Thursday, April 15, 2010 at 23:59:38 UTC. The shallow depth at which the quake struck could mean that some building close to the epicenter may have sustained some structural damage.

GFZ Potsdam – Earthquake Bulletin

  • Region: Utah
  • Time: 2010-04-15 23:59:41.8 UTC
  • Magnitude: 5.1
  • Epicenter: 111.04°W 41.79°N
  • Depth: 1 km [Fire Earth estimate]
  • Status: automatic
  • Distances [USGS/EHP]
    • 8 km (5 miles) ENE (57°) from Randolph, UT
    • 21 km (13 miles) NNE (13°) from Woodruff, UT
    • 23 km (14 miles) SE (127°) from Laketown, UT
    • 124 km (77 miles) NNE (32°) from Salt Lake City, UT

The quake occurred about 57 miles (92km) east of a magnitude 4.0event which struck the area also at a shallow depth on June 4, 2009.

Fire-Earth Moderators believe both of these quakes were caused by gas drilling activities.

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]
