1975 Ohio is on the periphery of the New Madrid Seismic Zone, an area in Missouri and adjacent states that was the site of the largest earthquake sequence to occur in historical times in the continental United States. When viewing the maps, it is important to remember that areas with high earthquake hazards do not necessarily face high seismic risks. A seismic zone is used to describe an area where earthquakes tend to focus; for example, the New Madrid Seismic Zone in the Central United States. This map is one of a series of seismicity maps produced by the U. S. Geological Survey that show earthquake data of individual states or groups of states at the scale of 1:1,000,000.

Download the latest version of This map shows only those earthquakes with epicenters located within the boundaries of Ohio, even though earthquakes in nearby states or countries may have been felt or may have caused damage in Ohio.The data in table 1 were used to compile the seismicity map; these data are a corrected, expanded, and updated (through 1983) version of the data used by Algermissen (1969) for a study of seismic risk in the United States. Four great earthquakes were part of a series at New Madrid in 1811 and 1812.

For best results viewing and printing PDF documents, it is recommended that you download The map also uses star icons to indicate the location of seismic stations throughout Ohio. The data in table 1 represent best estimates of the location of the epicenter, magnitude, and intensity of each earthquake on the basis of historical and current information. Many earthquakes were added to the original list from new data sources as well as from some old data sources that had not been previously used. https://www.americangeosciences.org/.../interactive-map-earthquakes-ohio These locations are represented on the map by a triangle. For each earthquake, users can click on the symbol to find out specific information and access a full earthquake report. A seismic hazard zone describes an area with a particular level of hazard due to A Roman numeral to the left of a triangle is the maximum Modified Mercalli intensity (Wood and Neumann, 1931) of all earthquakes at that geographic location. Seismic Design Maps. The number of earthquakes at each location is shown on the map by the arabic number to the right of the triangle. The year shown below each triangle is the latest year for which the maximum intensity was recorded.Part or all of this report is presented in Portable Document Format Although you may hear the terms “seismic zone” and “seismic hazard zone” used interchangeably, they really describe two slightly different things. browser may not display or print as intended.
