[Ed. – Hmmm. The grandparents used to live in the Walnut Hill area.]
[Scientists have] identified [a] fault line that runs right through Irving and into Dallas.
It is about 2 miles in length and 3 to 5 miles deep.
In the area of the newly identified fault are: buildings, businesses, high-rises, and residents.
The SMU seismology team says the fault stretches from state highway 114 in Irving and extends north-by-north east to Walnut Hill in West Dallas.
“This is not new faulting. This is not the formation of a new fault this is just reactivation of a fault that’s probably hundreds of millions of years old,” explains SMU Seismologist Heather DeShon. …
Dallas Mayor Mike Rawlings says the city is looking at it’s building codes. …
There hasn’t been a noticeable earthquake in that area since January 23rd, but researchers say they are measuring many tiny earthquakes.
