|Title: ||International cooperation during volcanic crisis: an example from the Italy-El Salvador monitoring system installed at Chaparrastique volcano, El Salvador|

|Abstract: ||On December 29th, 2013, after 12 years of inactivity, a new explosive
eruption occurred at Chaparrastique volcano (San Miguel, el Salvador)
prompting the evacuation of more than 5000 people. The new eruption
that occurred at the volcano has so far been an isolated single
explosion of vulcanian type, and was the first eruption since 2002,
when the volcano produced a small VEI 1 eruption. The explosion
produced an ash plume of considerable (5-10 km) height, generating
heavy ash fall in nearby areas downwind, such as in the towns of
Chinameca and San Jorge. Pyroclastic density currents also affected
the flanks, damaging the coffee plantations and small inhabited areas
around the volcano.
On January 2014, following a request of support by the government of
El Salvador, INGV (Istituto Nazionale di Geofisica e Vulcanologia),
organized a task force, V-Emer (Volcano Emergency) to improve the
existing monitoring network at Chaparrastque volcano.
During a 10 days campaign in El Salvador a temporary network was
successfully installed, and it is now run by the volcanologists of MARN
(Ministerio de Medio Ambiente y Recursos Naturales, El Salvador).
The network is composed of five broadband seismic stations, 3
infrasonic microphones, 2 radiometers, 10 GPS stations, 1 thermal
camera, 1 DOAS and 1 multi-gas geochemical station for measurement
of SO2 and CO2 fluxes, respectively. Since 27 January, significant collaborative efforts are being done
between MARN and INGV for the processing and interpretation of the
data collected during monitoring. For facilitating communication and
exchange between the members of the cooperation, a mailing list has
been created, and weekly meetings are attended by the members for
the discussion on a number of scientific and technical aspects. This
initiative seeks to make significant advance into volcano monitoring
network and data analysis, as well as improving international
cooperation during volcanic crisis management.
