  The Oklahoma Geological Survey Observatory is a research and public-service agency located in rural Tulsa County.

The Survey's mandate remains to study Oklahoma's geology, prepare and distribute reports, and promote wise use of the State's natural resources.

The Oklahoma Geological Survey Observatory in rural Tulsa County, south of Leonard is a comprehensive
geophysical observatory which records, identifies, and locates  30 to 167 animated gif of the word EARTHQUAKE shaking then crumbling in Oklahoma each year, and also records about five worldwide earthquakes per day.
