The 1867 Manhattan earthquake struck Riley County, Kansas, in the United
States on April 24. The strongest earthquake to originate in the state,
it measured 5.1 on a seismic scale based on reports of how strongly it
was felt in the area. Its epicenter was near the town of Manhattan. On
the Mercalli intensity scale, its maximum perceived intensity was VII,
"very strong". There were reports of minor damage in Kansas, Iowa, and
Missouri, according to the U.S. Geological Survey. It was felt as far
away as Indiana and Illinois, and perhaps Ohio, though the latter
reports have been questioned. Manhattan is near the Nemaha Ridge, a long
anticline structure that is bounded by several faults. A 2016 hazard
map from the U.S. Geological Survey estimated a 1% or lower risk for a
major earthquake in Kansas for the following year, though the nearby
Humboldt Fault Zone continues to pose a threat to the city, and
scientists from the agency think an earthquake of magnitude 7.0 remains
possible.
