...Cliff Frohlich; Chris Hayward; Brian Stump; Eric Potter Abstract This paper describes a sequence of small earthquakes ( m b ≤3.3) that occurred at the Dallas–Fort Worth Airport, Texas, between 30 October 2008 and 31 May 2009. Analysis of records at regional station WMOK identified more than 180...

... for shallow events near disposal wells so that proximate causes of induced seismicity can be assessed. In this study we show results from reanalyzing a small swarm of earthquakes (all less than M3.3) recorded on a local network near the Dallas-Fort Worth (DFW) airport in late fall 2008, using “best-in-class...

...Cliff Frohlich; Eric Potter; Chris Hayward; Brian Stump Abstract On 31 October 2008 and the following day, numerous Dallas-Fort Worth (DFW) residents called 911 to report experiencing several small earthquakes, accompanied by loud booming noises and the shaking of walls and furniture. Using data...

... earthquakes (M2.5 to 3.3) were felt between 31 October 2008 and 16 May 2009 in the Dallas-Fort Worth area ( Figure 1 ). Since these were the first seismic events reported by USGS in the area in modern history (from 1973), and the events were in the vicinity of a salt-water disposal (SWD) well which started...

...Seong Ju Jeong; Brian W. Stump; Heather R. DeShon; Louis Quinones ABSTRACT Earthquakes in the Fort Worth basin (FWB) have been induced by the disposal of recovered wastewater associated with extraction of unconventional gas since 2008. Four of the larger felt earthquakes, each on different faults...

DeShon ABSTRACT A generalized inversion technique (GIT) is applied to local seismic data from 90 induced earthquakes ( M L 2.0–3.9) in the Fort Worth Basin (FWB) of north Texas to separate path, site, and source characteristics and to improve local seismic...

...Elizabeth A. Horne; Peter H. Hennings; Johnathon L. Osmond; Heather R. DeShon Abstract From 2006 through mid-2018, there have been 125 Mw ≥ 2.5 recorded earthquakes within the Fort Worth Basin and the Dallas-Fort Worth metropolitan area. There is general scientific consensus that this increase...

Over the next decade, a series of faults activated across the basin, and by 2018, more than 200 earthquakes ranging in magnitude ( M ) from 1.6 to 4.0 had been reported in the U.S...

...Murari Khatiwada; G. Randy Keller; Kurt J. Marfurt Abstract The Fort Worth basin (FWB) is one of the most fully developed shale gas fields in North America. Although there are hundreds of drilled wells in the basin, almost none of them reach the Precambrian basement. Imaged by perhaps 100 3D...
