A swarm of more than 70 small earthquakes has rattled Oklahoma in the past week, raising concerns that the state’s quake problem is getting worse. The largest quake measured magnitude-4.8 and struck around midnight Wednesday near the town of Fairview. No significant damage has been reported, although it shook pictures and crockery. Oklahoma in 2014 had at least 5,415 earthquakes; 585 of them were magnitude-3 or greater. In comparison, the state had just 109 magnitude-3 quakes in 2013, according to the Oklahoma Geologic Survey. Statistics for 2015 are still being compiled. A state report last year noted a connection between hydraulic fracturing and some earthquake 'swarms,' and state officials say there's a potential risk to the public due to the increase in quakes.
