SYSTEM DESIGNED FOR THE ACQUISITION OF VOLCANIC SEISMICITY
This work presents a system created for the acquisition of volcanic seismicity. In order to prevent the danger of a volcanic eruption, volcanoes are monitored to determine the state on which they are. One of these parameters is the seismicity generated by the movement of ground. To monitoring this parameter, it is been created a low cost and low power system mounted in a waterproof case to be installed in hard environments with adverse conditions. It is an autonomous system built to be used in long- term campaigns. This equipment incorporates a low power microprocessor as the core of the system, three acquisition channels and a GPS to synchronize the time base. Data can be stored in a SD memory or it can be sent remotely via radio-frequency. The final tests show a correct acquisition of the system with an event produced in the Canary Islands.
