Chile and Costa Rica 2013

Chile and Costa Rica Expedition 2013

In February, 2013, three Volcanofiles — Yves, Nial, Kayla, and Kelby — headed to the southern hemisphere again. For one month, in collaboration with the Observatorio Volcanológico de los Andes del Sur (OVDAS) they monitored the activity at Villarrica, Chile. Then, the four ventured north into central America — Costa Rica, to be exact — to spend some time having a look at the very active Turrialba volcano plus quick trips to Arenal and Poas.

Villarrica Monitoring Campaign 2013

This project builds upon last year’s field campaign where our team successfully deployed an array of gas monitoring instruments at the Chilean volcanoes Lascar, Villarrica, and Puyehue. During this campaign we established a partnership with the regional observatory, Observatorio Volcanológico de los Andes del Sur (OVDAS). Villarrica volcano is currently monitored by OVDAS with a real-time seismic amplitude measurement system. However, no gas monitoring stations are in place resulting in a large gap in the monitoring programme therefore limiting the information available for hazard assessment and eruption forecasting. We will introduce state of the art gas monitoring instruments and data interpretation to OVDAS personnel, who will in turn educate us about the practicalities of integrating their use into a long term monitoring programme. In addition, we are planning on obtaining very high resolution gas monitoring data of degassing at Villarrica since preliminary results from last year’s campaign indicate a possible cyclical behaviour of the volcano’s summit lava lake.

Instrumentation:

  • UV Spectrometers (DOAS methodology) with Volcanofiles’ own home-brewed AvoScan technology!
  • UV Camera — Kelby’s baby
  • MICTOROPS II Sun Photometer — to measure volcanic aerosols. It’s the machine that goes “bing!”
  • Multi-gas sensor — developed by the Istituto Nazionale di Geofisica e Vulcanologia (INGV) in Palermo to measure relative proportions of H2, CO2, H2O, H2S, and SO2.
  • Satellite remote sensing — What can we learn about Villarrica… from space?

Costa Rica

On their way back to England, the Volcanofiles will take a little detour to one of the most volcanically active countries in the world — Costa Rica. There they’ll be focusing their efforts on Turrialba volcano plus trips to Rincón de la Vieja, Arenal, and Poas. See our post, “We’re in Costa Rica!” for all the info.
