Just in time for a new Hollywood movie on fracking! The earthquake injection scene has totally slacked off in recent months, as more people follow the Ohio Rules. This earthquake might be a leftover, or those darn Okies are just stubborn
Update: Ohio Rules call for no injection into the Precambrian and to stop if there are earthquakes. Nevertheless, they don't know what they are doing, and I predict that the next big story will be the over-injection of the Cambrian sandstone layer.
