2 IRIS Workshop 18-19 Feb, 2008 Boston Out of Africa Workshop

3 IRIS Workshop 18-19 Feb, 2008 Boston Out of Africa Workshop Red Sismológica FUNVISIS 35 BB 134 accelerometers Communicated by Dr. Herbert Rendon VENEZUELA

4 IRIS Workshop 18-19 Feb, 2008 Boston Out of Africa Workshop

5 IRIS Workshop 18-19 Feb, 2008 Boston

6 Out of Africa Workshop Red Sismológica de Los Andes Venezolanos (Univ. de Los Andes) 11 stations

7 IRIS Workshop 18-19 Feb, 2008 Boston Out of Africa Workshop Observatorio Sismologico Sud Occidental (OSSO) Instituto Colombiano de Geologia y Mineria (INGEOMINAS) Universidad de Quintio Observatorio Sismologico Colombia Universidad Nacional (CdM)

8 IRIS Workshop 18-19 Feb, 2008 Boston Out of Africa Workshop La red cuenta con 18 estaciones sismológicas que desde 1993 han funcionado de manera continua, a fin de monitorear y caracterizar los eventos sísmicos que se presenten en el área. Adicionalmente, los Observatorios Vulcanológicos y Sismológicos de Pasto y Manizales comparten datos de las estaciones GCAL y BIS1, respectivamente. http://www.ingeominas.gov.co

9 IRIS Workshop 18-19 Feb, 2008 Boston Out of Africa Workshop La red está compuesta de 120 acelerógrafos digitales con los cuales se ha podido generar una gran base de datos de registros sísmicos. De los 120 instrumentos existentes, 32 de ellos (ubicados en Bogotá) han empezado a generar registros para la calibración del estudio de microzonificación sísmica existente de la ciudad.

10 IRIS Workshop 18-19 Feb, 2008 Boston Out of Africa Workshop Instituto de Geofisica Escuela Politecnica Nacional Ecuador

11 IRIS Workshop 18-19 Feb, 2008 Boston Out of Africa Workshop El Instituto Geofísico tiene instaladas 43 estaciones sísmicas de período corto en la parte centro y norte del país y las Islas Galápagos. Las estaciones forman parte de la Red Nacional de Sismógrafos (Red Sísmica Nacional), la cual registra no solamente la actividad tectónica sino también la actividad de 8 volcanes, que actualmente no representa alto riesgo para la población. Adicionalmente el Instituto mantiene tres redes locales en los tres volcanes más peligrosos. Estas redes están complementadas con el monitoreo de la deformación, de los lahares y geoquímica de cada uno de ellos.

14 IRIS Workshop 18-19 Feb, 2008 Boston Out of Africa Workshop Communicated by J. Hernando Tavera Green: digital BB Red: Digital SP Five stations will transmt via satelite, No decided yet which ones. Criteria to delect them, good azimuthal coverage. This year stations will be installed at: Tumbes, Piura, Chiclacyo, Iquitos, Ayacucho (Coracora). Perhaps Drs. Edmundo Norabuena and Daniel Huaco can tell us more.

25 IRIS Workshop 18-19 Feb, 2008 Boston Out of Africa Workshop Centro Regional del Sismologia para America del Sur (CERESIS) es una organización autónoma, producto de un acuerdo de cooperación regional e internacional para el avance de la sismología y la reducción de los riesgos por terremotos y fenómenos afines. En la actualidad son 12 los Estados Miembros: Argentina, Bolivia, Brasil, Chile, Colombia, Ecuador, España, Paraguay, Perú, Trinidad y Tobago, Uruguay, Venezuela. Comision Permanente del Pacifico Sur: Members in South America are Colombia, Ecuador, Peru and Chile. Together with UNESCO/ITIC to develop a Regional Tsunami Center (Lima meeting next week) CTBTO stations Other organizations in South America:

26 IRIS Workshop 18-19 Feb, 2008 Boston Out of Africa Workshop After the IRIS Workshop held in Sao Paulo in 2006, on managing database and waveform data, it was evident that what is most needed are small training courses with few key people to actually learn things with hands-on training. The Sao Paulo workshop was good in motivating people and showing all aspects of a network (from installation to processing). But it was too theoretical, perhaps more practice with computers should have been scheduled. Regarding the needs: training, permanent colaboration, maintenance, regional support, but mainly software to help build the capacities to analyze seismological data. In our country we need a transportable seismic network of at least 12 stations for two years (at least) to monitor several faults. There are faults that have not been staudies at all and most likely will generate earthquakes in the future. A final word: Some suggestions/requests
