![]() ![]() Carpenter credits Mammoth Cave National Park staff, Park Research Coordinator Rick Toomey in particular, as being instrumental in the success of the project. Geological Survey reports, a 2.6 magnitude earthquake was detected Thursday morning in central Kentucky. A magnitude 3.0 earthquake was reported in Adams County, Ohio, and felt by some Northern Kentucky residents Sunday afternoon, according to the United States Geological Survey. The project was funded by KGS with instrumentation support from Nanometrics Inc. The Mammoth Cave data may also be used for new research opportunities related to cave processes. Earthquake research helps state government agencies, local governments, nongovernmental organizations, and the public to develop appropriate mitigation measures for reducing potential earthquake losses. The Mammoth Cave station data will be useful to seismologists and earthquake researchers at KGS and beyond. The addition of the Mammoth Cave station will provide a clearer seismic picture of Kentucky. The network consists of 24 permanent seismic and strong-motion stations. The information is incorporated into the real-time earthquake monitoring conducted by KGS as part of the Kentucky Seismic and Strong-Motion Network. The seismic data is conveyed to computers at KGS within seconds of when it is produced. How many quakes were there in Kentucky in the past 48 hours In the past 48 hours, Kentucky, USA had 1 quakes up to magnitude 1.7. 1.7 earthquake - 6 Km NW of Tiptonville, Tennessee, on Sunday, at 6:28 pm (GMT -6). The highly sensitive Mammoth Cave broadband seismometer records small ground motions, on the scale of nanometers, across a broad range of frequencies. The last earthquake in Kentucky occurred 1 day 11 hours ago: Minor mag. Installation at this depth shields the seismometer from the impact of human activity, wind and temperature fluctuations. A pipe known as the Upside-Down Well provides the conduit for the power, communications and GPS-antenna cables that reach 275 feet below the ground surface. The USGS and its partners monitor and report earthquakes, assess earthquake impacts and hazards, and. Kentucky is affected by several seismic zones - the New Madrid and Wabash Valley Seismic Zones to the west and the Eastern Tennessee Seismic Zone to the east - and occasional earthquakes that occur outside those zones.Īfter extensive research, KGS located an existing bedrock face in an infrequently visited passage in Mammoth Cave that was ideal for the station installation. The USGS Earthquake Hazards Program is part of the National Earthquake Hazards Reduction Program (NEHRP), established by Congress in 1977, and the USGS Advanced National Seismic System (ANSS) was established by Congress as a NEHRP facility. ![]() KGS seismologist Seth Carpenter says this new station fills an earthquake monitoring gap in south-central Kentucky. Seismologists with Kentucky Geological Survey (KGS) and Mammoth Cave National Park staff installed a new seismic monitoring station last month within the cave system.
