Abstract
Since November 2016, Instituto Volcanológico de Canarias (INVOLCAN) started the deployment of a broadband seismic network on Canary Islands: Red Sísmica Canaria (RSC) (FDSN code C7; http://doi.org/doi:10.7914/SN/C7) with both scientific research and volcano monitoring purposes. The network started with the installation of 15 broadband stations adquired throught the MAKAVOL project (MAC/3/C161) in Tenerife and Gran Canaria islands. All the stations consist in Nanometric Trillium Compact sensors equipped with a Centaur datalogger.
This first nucleus of the network was devoted to the monitoring of volcanic seismicity of Tenerife Island. It was able to record the increase of the seismicity in 2017, because of a pressurization fo the hydrothermal system of the island, testified by the 5-fold increase in the diffuse CO2 emission from the crater of Mt. Teide volcano (Tenerife).
Another improvement of the network was the acquisition of 15 more broadband stations in the framework of the VOLRISKMAC project (MAC3.5b/124; http://volriskmac.com). These new stations were deployed on Tenerife and La Palma islands and will be deployed on Gran Canaria and La Gomera islands as well. The first 5 stations on La Palma were deployed during the Octuber 2017 seismic crisis, related to a sub-crustal magmatic intrusion beneath the magmatic system of Cumbre Vieja volcano.
We show the improvement of the detection capability and of the network performances during the network development as well as some relevant results of this first 18 months of network operativity.
