| Zusammenfassung |
| Teide-Pico Viejo complex stands for one of the major natural volcanic hazards in the Canary
Islands, due to the expected types of eruptions in the area and the high number of inhabitants
in Tenerife Island. Therefore, it is necessary to have a volcanic alert system able to afford a
precise assessment of the current state of the complex. For this purpose, the knowledge
of the expected signals at each volcanic activity level is required. Moreover, the
external effects that can affect the measurements shall be distinguished, external
influences as the atmosphere are qualitatively known but have not been quantified
yet.
The objective of the project is to collect, analyze and jointly and continuously evaluate
over time geophysical, geodetic, geochemical and meteorological data from the Teide-Pico
Viejo complex and its surroundings. A continuous multiparametric network have been
deployed in the area, which, together with the data provided by the Volcano Monitoring
Network of the Instituto Geográfico Nacional (IGN) and data from other institutions will
provide a comprehensive set of data with high resolution in both space and time.
This multiparametric network includes a seismic array, two self-potential lines
for continuous measurements, five magnetometers and two weather stations. The
network will be complemented with 8 CGPS stations, one tiltmeter, 10 seismic
stations, and four thermometric stations on the fumaroles of Teide volcano that
IGN already manage in Tenerife. The data will be completed with the results from
different repeated surveys of self potential, soil temperature and CO2 diffuse flux
in several pre-established areas on top of Teide throughout the entire duration of
project.
During the project, new computation tools will be developed to study the correlation
between the different parameters analyzed. The results obtained will characterize
the possible seasonal fluctuations of each parameter and the variations related to
meteorological phenomena. In addition, they will allow identifying the response of all the
analyzed parameters to specific events that are traditionally studied with a single
technique, such as short episodes of tremor (sporadically registered in Teide-Pico Viejo
surroundings) or changes in activity of the hydrothermal system of the volcanic
complex.
We present here the first multiparametric results obtained from the project, including
locations with the seismic array, CO2 and temperature maps of Teide fumaroles zones and
magnetometric measurements. |
