There have been earthquakes in almost every corner of Texas since the start of the state's most recent oil and gas boom. One swarm that really captured people’s attention started in the town of Azle in 2013. When oil and gas regulators at the Railroad Commission of Texas visited the town, local people suggested ways to handle the waste water disposal wells thought to be causing the quakes. One idea came up over and over again.
“Why is it we can't shut the wells down around here for a period of time?” asked resident Gale Wood. "If nothing happens after a while, that would be one way to determine what’s going on."
