Map shows the location of today’s M=4.2 earthquake in Oklahoma. This quake was widely felt throughout the state, and was also felt in 4 other surrounding states based on USGS felt reports.
At 8:47 a.m. local time this morning, a M=4.2 earthquake struck central Oklahoma in between the cities of Oklahoma City, Tulsa, and Stillwater. This was followed by five aftershocks, the largest of which was a M=3.8. At 10 a.m. local time, there have been over 1,500 felt reports from the mainshock on the USGS website, from all over the state of Oklahoma, and even in Wichita, Kansas, over 200 km away.
So far, there are no reports of damage, which is unlikely given this quake's moderate magnitude. Additionally, the USGS PAGER system estimates that economic losses should remain extremely minimal, and any fatalities are very unlikely.
According to the USGS, today's earthquake occurred at a depth of 9.3 km, and was right-lateral strike-slip in nature. This depth is relatively deep for Oklahoma, but still within the range frequently seen. Based on the fault map shown in the Temblor map above, and the strike-slip component of today's earthquake, it occurred on an unmapped fault in the region.
Comment: The Weather Network reported almost baseball-sized hail battered homes in Alberta with reports of a tornado touching down near Breton.
