[Daily article] April 24: 1867 Manhattan, Kansas earthquake

The 1867 Manhattan earthquake struck Riley County, Kansas, in the United

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

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
