Earthquakes in Oklahoma

The Oklahoma Geological Survey and the US Geological Survey recently released a statement on the ongoing earthquake activity in that state.  They noted that the rate of earthquake activity has increased remarkably in the state, with 145 earthquakes having magnitude M>3 since January, 2014.  That currently makes Oklahoma the most seismically active state in the US.  Below we reproduce an image from that report.

We can use the hazard viewer to determine how these events translate into increasing probability of large earthquakes having M>5.  We select a region encompassing the most active area:

The blue curve below shows the probability of an M>5 earthquake occurring within 1 year in the blue circular region, and how this probability changes with time:

 

We see that currently, the probability of an M>5 earthquake occurring within the blue circle during the next year is about 16%.  It has increased from about 1%, the value it had prior to late 2011.  This is about when the fluid injection into deep geologic formations in Oklahoma began.

With the passage of time, the ratio of earthquakes is rising in a different state and that cause of big damage every year. The government must aware people about upcoming threads and shift public to the safe place. Thanks for having such informative type my paper based website about earthquakes which would be helpful to analyze on behalf of previous reports.
