volcanic erupting under the area

Oklahoma?

Yes, a volcano can form anywhere, not just on fault lines.

The fact there are geysers there suggest that there is a magna chamber underneath them, heating the water and creating the geysers.

Good news is more volcanoes are dormant, but this increase in the activity in those geysers should raise a few eyebrows.

I wonder, has there been an increase in tremor activity in the area?
