## Soon : a semi-automated validation and correction tool

In order to decrease the delays for data and metadata validation and to reduce manual workload, all semi-automatic procedures and tools in use in all 3 observatories are going to be merged and upgraded in a single software solution, with modules for future evolutions.

This development will be done by IPGP and will be funded by RESIF.

IPGP volcanic and seismic observatories are situated on tropical islands which are threatened by hurricanes. In 2017, two major hurricanes (above Saffir-Simpson category 3) have impacted the Antilles : **IRMA** on September 6th, 2017 and **MARIA** on September 18th and 19th, 2017, both category 5.

Those two hurricanes have caused damages on IPGP monitoring networks, particularly on OVSG network :

* Saint-Barthélémy broad-band station (WI.SBLM) has ceased transmission since IRMA eye passage.

* MARIA has damaged part of OVSG roof, leading to water invasion and electric damages on the installations.

* Some of Soufrière stations solar panels were wiped out and Wifi antennae damaged.

* VSAT reception antennae - the hub - have been damaged by MARIA. It's now out of service.

However, despite the electric shutdown in Martinique

observatory (less than 24 hours) caused by rain infiltration, the vast majority of the regional broad-band network (WI network) have not been impacted. The three reception hubs (Guadeloupe, Martinique, Trinidad) design allowed to quickly route the data distribution of all the network from Martinique observatory.
