The 1867 Manhattan earthquake
struck Riley County
, 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 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. (Full article...
