The U.S. Geological Survey reported a 5.0 magnitude earthquake early Thursday morning in Texas, with an epicenter 38 kilometers south-southeast of Spearman. Residents in Oklahoma reported tremors from the quake, putting Miami, Texas, in the same range of concern as the area closest to the epicenter.
No damage or injuries had been reported at the time. No aftershocks had been reported either, but the USGS said they could remain possible for up to one week after the initial quake.
Spearman epicenter
The reported location places the quake near Spearman rather than inside a larger population center. That kind of distance from the epicenter can still be enough for people farther away to notice shaking, which fits the reports from Oklahoma.
The USGS did not report a larger sequence of quakes alongside this one. For readers in Texas and Oklahoma, the practical point is straightforward: the first report showed a single 5.0 magnitude event, and the follow-up period still carried some risk of additional shaking.
Oklahoma tremors
Residents in Oklahoma felt the earthquake even though the reported epicenter was in Texas. That means the shaking traveled beyond the state line, and it gives people in both states a reason to watch for any change over the next several days.
The source does not explain what caused the earthquake. For now, the clearest next step is to pay attention to any new USGS updates during the week after the initial quake, when aftershocks could still develop.
