Our field trip studying Tectonic Hazards and Volcanic Landscapes involves a visit to the Garrotxa Volcanic Park. This is an area of some 40 monogenetic volcanic cones. All were formed very recently with the last eruption 11,000 years ago.
Although the volcanoes in the region have been inactive for over 11,000 years, a lot of research has been undertaken to risk assess and map relative hazard levels in the region.
Our fieldwork will closely follow the methodologies used in volcanic and tectonic hazard assessments. Students will undertake small scale tectonic and volcanic hazard and susceptibility mapping exercisesin Olot town and surroundings.
We will supplement the field data with a range of secondary data from local meteorological stations and lava volume and ash fall estimates to feed into some simple computer models, with the end result being a map showing levels of risk and to both ash fall and lava flow.
We will visit the Croscat volcano which has been extensively quarried in the past. These quarries now provide unrivalled access for educational groups to study lava flows, pyroclastic deposits and volcanic ash deposits. We will also climb to the summit of the volcano and to examine the way in which the pattern and nature of settlements and economic activity have made use of this stunning volcanic landscape.
