In the source text about induced seismicity from wastewater wells used in hydraulic fracturing (fracking), which state shows a 0.1 or higher peak acceleration of standard gravity within natural gas supply areas (Natural Gas Supply Areas - North America layer) that is likely not due to natural earthquake causes near plate boundaries or major fault lines: Oklahoma, Michigan, Wisconsin, Missouri, or South Dakota?

What the question is really asking

You are looking for a place where earthquake hazard is high (peak acceleration $\ge 0.1g$) in the same places as natural gas activity, but where the earthquakes are less likely to be explained by normal plate-boundary tectonics.

Using the layers to spot induced seismicity

• The Earthquake Hazard Areas (United States) layer highlights where strong shaking is expected (peak acceleration values).
• The Natural Gas Supply Areas (North America) layer highlights where natural gas extraction and related infrastructure are concentrated.
• Induced seismicity is most suspicious where these two layers overlap in an intraplate area (not near a major plate boundary).

Checking the answer choices

• Oklahoma: Not near a plate boundary, yet it has well-known clusters of earthquakes associated with wastewater disposal wells and shows areas with about $\ge 0.1g$ hazard overlapping energy activity.
• Missouri: Has naturally higher hazard due to the New Madrid Seismic Zone, which is a major natural fault system, so it does not fit the “likely not natural causes” clue.
• Michigan, Wisconsin, South Dakota: Generally low seismic hazard on national peak-acceleration maps and do not typically show $\ge 0.1g$ patterns tied to gas supply areas.

Why Oklahoma is the best match

The combination of (1) high mapped shaking potential (around $0.1g$ or more), (2) overlap with natural gas-related areas, and (3) location away from plate boundaries points most strongly to induced seismicity in Oklahoma.
