GASPAR, J.L., MIRANDA, M., SENOS, M.L., MATIAS, L., SILVEIRA, G. (2002) - SUMMO/AÇORES Sistema Unificado de Monitorização e Modelação Geofísica para a Região dos Açores. Azores. “II Momar Workshop”. Faial, Horta, 15 - 17 de Junho (Poster).


SUMMO/AÇORES is a project directed to the development of the Azores regional geophysical network that started in 1997 with the well-succeeded cooperation between the Azores University and the Meteorological Institute. The main objective of the project is to update and improve the existing geophysical networks creating a structure to serve the scientific community, the civil protection and the public in general.
The safety of populations exposed to geological risks such as earthquakes and volcanic eruptions obliged to the existence of monitoring networks based on independent techniques. In Portugal, this subject is particularly important for regions like the Azores, where earthquakes and volcanic eruptions are a permanent threat to all the inhabitants.
The different technologies of seismic monitoring associated with accurate GPS observations are basic tools to achieve such goals. All these primary geophysical techniques are powered by the possibility to use real-time or near-real-time raw data, an essential point when dealing with civil protection actions.
To fulfil these objectives we pretend to:
·  consolidate the SIVISA (Sistema de Vigilância Sismológica dos Açores – Azores Seismological Surveillance System) through the real integration of all the Azores University and Meteorological Institute existing seismic monitoring facilities, into a unique, comprehensive system, with high operational standards, able to make available real-time high quality geophysical data through an open communication network;
·  complement the SIVISA Network with Ocean Bottom Seismometers in order to cover the volcano-tectonic activity that take place in the Azores submarine geological structures;
·  integrate of all the Azores GPS permanent stations in the same monitoring system, building a consistent database for multidisciplinary studies;
·  develop an emergency national task force based on the existence of portable equipment to attend any seismic or volcanic crisis;
·  combine geophysical and geodetic techniques to collect the most reliable and accurate information on geological risks;
·  develop technical expertise to install, maintain and give support to all basic data providers, and to assure high information fluxes between providers and users, either professional or individual;
·  implement of an efficient data dissemination system with specific access levels for researchers, civil protection authorities and general public;
·  develop collaboration at all levels between public and private institutions, between state laboratories and research centres and between national and international observation networks;
