Earthquakes decline in Oklahoma in 2012
The number of small Oklahoma earthquakes was down in 2012. There has been a significant increase in earthquakes in recent years, however.
The number of earthquakes in Oklahoma declined in 2012 after a two-year spike, said Austin Holland, a seismologist at the Oklahoma Geological Survey in Norman.
Holland moved to Oklahoma to study the sudden swarm of earthquakes that started in late 2009.
