![]() ![]() Radio astronomy is a common link between San Pedro de Atacama and Magdalena. The visit is part of a Sister Cities program initiated and funded by AUI, which operates the NRAO for the U.S. "These teachers will learn much about New Mexico, the United States, and our educational system, and will take this new knowledge back to their students and their community," said NRAO Education Officer Robyn Harrison. They also will meet local residents, tour the Bosque del Apache National Wildlife Refuge with a second-grade class, visit an area ranch, tour the Very Large Array (VLA) radio telescope, and see Socorro's Community Arts Party. Myriam Nancy Rivera Mercado, Head of the high school in San Pedro, Gabriela Fernanda Rodriguez Moraleda, a tourism teacher there, and San Pedro Mayor Sandra Berna Martinez will begin a visit that includes classroom observations in the Magdalena schools, a reception hosted by the Magdalena Village Council, and a Mayor's Breakfast with Magdalena Mayor Jim Wolfe. They will be accompanied by their town's mayor. (AUI), the nonprofit research corporation that operates the National Radio Astronomy Observatory (NRAO). Two teachers from the town of San Pedro de Atacama, in the northern desert of the South American nation of Chile, arrive in Magdalena, New Mexico, Sunday, January 28, for a two-week visit that is part of a Sister Cities program sponsored by Associated Universities, Inc. Moreover, with this new ML scale the seismicity caused by tectonic or fracking activity at VMM region can be monitored more accurately.Ĭhilean Teachers Begin Exchange Program Visit in Magdalena With this new scale ML values are adjusted to local conditions beneath VMM region leading to more realistic ML values. Higher values of ML were obtained for VMM region compared with those obtained with the current formula used for ML determination, and with California formula. The derived local magnitude scale for VMM region was: ML =log(A) + 1.3744 âˆ- log(r) + 0.0014776 âˆ- r - 2.397 + S Where A is the zero-to-peak amplitude in nm in horizontal components, r is the hypocentral distance in km, and S is the station correction. Local magnitude scale for Valle Medio del Magdalena region, ColombiaĪ local Magnitude (ML) scale for Valle Medio del Magdalena (VMM) region was defined by using 514 high quality earthquakes located at VMM area and inversion of 2797 amplitude values of horizontal components of 17 stations seismic broad band stations, simulated in a Wood-Anderson seismograph. ![]()
