Bass Islands Dolomite outcrop with stalactites in a cave on South Bass Island, Put-In-Bay Township, Ottawa County, Ohio. This area has dolomite, anhydrite, gypsum, salt and shale lithologies. Bedrock is from the Silurian Geologic Period. The slide image was created in 1952 by Philip M. Smith for the Ohio Cave Survey Project. The Ohio Cave Survey Project was formalized in 1952. The Central Ohio Grotto of the National Speleological Society in cooperation with the Ohio Geological Survey established a comprehensive survey of Ohio caves and caverns. The location is approximate to the center of the island.

The purpose of this study is to evaluate tsunami hazard for the community of Seward and northern Resurrection Bay area, Alaska. This report will provide guidance to local emergency managers in tsunami hazard assessment. We used a numerical modeling method to estimate the extent of inundation by tsunami waves generated from earthquake and landslide sources. Our tsunami scenarios included a repeat of the tsunami of the 1964 Great Alaska Earthquake, as well as tsunami waves generated by two hypothetical Yakataga Gap earthquakes in northeastern Gulf of Alaska, hypothetical earthquakes in Prince William Sound and Kodiak asperities of the 1964 rupture, and local underwater landslides in Resurrection Bay. Results of numerical...
Potential tsunami hazards for the Fox Islands communities of Unalaska/Dutch Harbor and Akutan were evaluated by numerically modeling the extent of inundation from tsunami waves generated by hypothetical earthquake sources and taking into account historical observations. Worst-case hypothetical scenarios are defined by analyzing results of a sensitivity study of the tsunami dynamics related to various slip distributions along the Aleutian megathrust. The worst-case scenarios for Unalaska and Akutan are thought to be thrust earthquakes in the Fox Islands region with magnitudes ranging from Mw 8.8 to Mw 9.1 that have their greatest slip at 30-40 km (18-25 mi) depth. We also consider Tohoku-type ruptures and an outer-rise...

A view of slump down from the Monticello Village Apartments landslip in Athens, Athens County, Ohio. The Monticello Village Apartments was a complex of fourteen to sixteen buildings when construction was finished in 1968. The level area on which the apartment buildings were constructed was fashioned from a cut on the hillside in the Clarksburg red bed. The mudstone removed in this cut was used as fill on the edge of the hill in order to expand the level area for apartment construction. On November 4, 1972, the slope failed, causing the destruction of a 150 meter section of Hastings Road in the location of Ohio State Route 32. On November 7, 1972, four buildings were evacuated after additional rapid movement of the...

Scarp caused by the landslide that developed during construction of Ohio State Route 32 near Jasper in Pike County, Ohio. The image was taken on March 11, 1972.
Shore erosion at Blackmore Road along the Lake Erie shoreline in Perry Township, Lake County, Ohio. The image was taken by David K. Webb on May 27, 1970.
Drilling a seismic borehole for the National Seismic Network at Mendenhall Laboratory on the main campus of The Ohio State University, Columbus, Franklin County, Ohio. Sprowls Drilling Company of Sunbury, Ohio, did the drilling work for the borehole. At a depth of 125 feet, in the Columbus Limestone, a cavern was encountered. An unsuccessful attempt was made to plug the cavern. The site was abanonded as a location in the United States Geological Survey's nationwide network of seismographs because of the condition of the limestone on the campus of The Ohio State University. The image was taken by Michael C. Hansen in August 1993.
The saw yard at the Waller Brothers Stone Company's Buena Vista Sandstone quarry operation near McDermott, Scioto County, Ohio. Unit lithology in this area is shale interbedded with siltstone, sandstone and conglomerate of the Cuyahoga Formation. Bedrock is from the Mississippian Geologic Period. The photograph was taken on September 3, 1969 probably by David K. Webb.
