Abstract
The permanent MQ network is composed of stations geographically distributed mainly on La Montagne Pelée volcano edifice, and on a broader extension on the whole Martinique Island.
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.
Ground sensors are buried in the ground, providing environmental insulation (seismometers), or inside deep (60m) or shallow (7m) boreholes (3 tiltmeters).
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), Halliburton/Pinnacle self-levelling borehole electrolytic tiltmeters - sampling rate of 1 min or 1 s. They are installed by pairs.
Rain gauges are "Précis-mécanique" and Vaisala products are used for other weather sensors.
Magnetic stations network was dismantled in 2005.
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.
