Iron County Emergency Management works to prepare for earthquakes and other disasters

They say practice makes perfect, and on the subject of earthquakes in Utah, it’d be wise to plan ahead. Have you discussed your plan with friends and family in the event of a large earthquake? Do you have an emergency kit made up? The Southwest Utah Public Health Department, along with several partner agencies, will be holding an earthquake drill on March 17, 2016 throughout southwest Utah. Find more information in the article on how you can participate and help preparedness efforts.

Geologic Map of the Panguitch Lake Quadrangle, Garfield and Iron Counties

By: Robert F. Biek, John J. Anderson, Edward G. Sable, and Peter D. Rowley

The Panguitch Lake quadrangle lies in the central part of the Markagunt Plateau in southwest Utah and includes Panguitch Lake, a popular area of summer and winter recreational use. Despite the plateau’s relatively simple structure of a gently east-tilted fault block, the quadrangle contains scenic and instructive exposures of southwest Utah’s youngest basaltic lava flows, classic examples of inverted valleys capped by older lava flows, glacial deposits in the Castle Valley area, and the southern margin of the Markagunt Megabreccia. The Megabreccia is the debris of Utah’s largest catastrophic landslide deposit, which covers 1300 square miles (3400 km²) of the northern and central Markagunt Plateau.
