Earthquake Information:
Southwestern Colorado experienced a moderate earthquake just before midnight on August 2, 1955 (local time). Murphy and Cloud (1957) and the USCGS quarterly series “Abstracts of Earthquake Reports” described the effects of the shock and assigned MMI values. Intensity VI was reported at Lake City, where one chimney was cracked and another fell (Figure 15). The U.S. Fisheries Station 19 km southwest of Creede, a location 32 km southwest of Creede, and Silverton reported MMI V. Two foreshocks were also recorded. Murphy and Cloud (1957) suggested the earthquake was felt over 5,200 km 2 , whereas the isoseismal map in Figure 15, indicates the felt area to be approximately 4,600 km 2 . Hadsell (1968) reported the size at 15,600 km 2 .
