The permanent GL network is composed of stations geographically distributed mainly on La Soufrière volcano edifice and on all the islands of Guadeloupe.
The stations all share the following features:
(1) power: solar panels and battery,
(2) telemetry: radio, wifi, 4G, or Very Small Aperture Terminal, and
(3) sensors: seismometers, tiltmeters and weather sensors.
Some of the stations are multi-sensors.
Most of the time, sensors are separated from the electronics in order to avoid any electric, magnetic and thermal mutual influence.
Seismometers are middle-band Güralp CMG40T, Nanometrics Trillium Compact 120s (regular and posthole versions), or short period L4-1Hz.
Tiltmeters are IPGP "home-made" BLUM tiltmeters (this network was stopped in 2008).
The deformation of the dome are manully measured with extensomters and creep-meters every month.
Rain gauges are "Precis-mecanique" and Vaisala products are used for other weather sensors.
Magnetic stations network was dismantled in 2005.
Two tide gages participate to the Caribbean tsunami warning system, the primary sensor is a radar associated with a meteorological sensor.
All data are disseminated in miniSEED and stationXML FDSN formats. Seismic data of this network are disseminated both in real time (raw data) and after validation.
