Monitoring equipment and volcanic hazards maps

1)  SABANCAYA Volcano

·         Real time seismic broadband network of three permanent stations linked to IGP’s Observatorio Volcanologico de Arequipa (IGP-OVA).  Hardware includes Guralp’s CMT-40 sensors and Reftek 130A portable recorders. In operation  since February 2013

·         5 portable Guralp CMG-6TD seismic stations operate around the volcano since February 2013.

·         10 GPS bench marks for volcanic deformation installed in 1998

 

Maps of potential volcanic hazards:

·         1:500,000 (1988)

·         1:250,000 (1990)

·         1:100,000; 1:250,000 (1992)

·         1:500,000 (2002)


2) MISTI Volcano

·         Real time short period seismic network composed of 5 permanent stations.  Telemetry link to IGP’s Observatorio Volcanologico de Arequipa (OVA). Hardware includes Kinemetrics SS1 1s/1Hz sensors. In  operation since October 2005.

·         5 GPS bench marks for volcanic deformation installed in 2001.

·         2 EDM baselines installed on SW and NE sides (2001)

·         Map of Self-Potential  1:100,000, based on 10 radial profiles from the
top to the base of the volcano.

·        Self-potential monitoring on a complete SW profile, each six months.

 

Maps of potential volcanic hazards:

 

·         1:250,000 (1998)

·         1:100,000 (2002)

 

3) UBINAS volcano

·         Real time broadband seismic network composed of 4 permanent stations. Telemetry link to IGP’s Observatorio Volcanologico de Arequipa (OVA). Hardware includes Guralp’s CMT40 and Reftek recorders. In operation since 2006.

·         2 Tiltmeters operating in real time since 2006.

·         4 GPS bench marks for volcanic deformation installed in 2006.

·         2 EDM baselines installed on NW and NE sides (2006)

·         Map of Self-Potential, 1:100,000, based on 9 radial profiles from the top to the base of the volcano.

·         Self-potential monitoring on a complete NW profile, each year.

·         Map of potential volcanic hazards: 1:500,000 (2002)

4) TICSANI volcano

·         4 GPS bench marks for volcanic deformation installed in 2006.

·         Map of potential volcanic hazard: 1:500,000 (2002).

NOTE 1: Most former volcanic hazard maps have update versions prepared by INGEMMET (Instituto Geológico Minero y Metalúrgico). 

 

NOTE 2: IGP-OVA and the younger INGEMMET volcanological team (OVI) will join together to build a stronger Observatorio Volcanológico del Sur del Perú that will ensure a high quality monitoring, surveillance, and research of the active volcanoes of the region.
