The ground around a northern Colorado wastewater injection well has been relatively quiet for more than two months, offering hope that a 10-month string of more than 200 small earthquakes might have subsided.
State regulators say an injection well near the location of two small earthquakes in Weld County didn’t violate its state permit or break any state rules.
The commission investigating seismic activity near wastewater disposal sites in Weld County met Friday afternoon to discuss developments since it ordered an injection well temporarily shut down.
A geophysicist from the University of Colorado is hoping to settle the question of whether a small earthquake last weekend near Greeley was caused by wastewater injection wells.
Emergency planners say most Coloradans are unprepared for an earthquake even though officials have spent years studying the consequences of a big one.
