(Reuters) - A magnitude 5.5 earthquake struck Antofagasta in Chile on Saturday, European- Mediterranean Siesmological Centre (EMSC) said.303-273-8500. The National Earthquake Information Center (NEIC), was established in Rockville, Maryland, in 1966 as part of the National Ocean Survey of the Department of Commerce. The Coast and Geodetic Survey, a forerunner of the National Ocean Survey, had coordinated the collection of seismological data in the United States for many years.
