New temperature logger installed on Galway’s Mountain
On 24 November 2021, Dr Adam Stinton installed a new temperature logger in a small area of fumaroles on Galway’s Mountain, about 900 m southeast of the summit of the current lava dome at Soufriere Hills volcano.
This installation replaces a previous temperature probe and data logger that succumbed to the highly corrosive conditions in the fumaroles. The temperature probe is now protected by a ceramic protection tube and buried to a depth of approximately 35 cm. The data logger (in the blue pelicase) will record the ground temperature every 10 minutes and needs to be manually downloaded on a regular basis.
This data will then be analysed to look for long-term trends in the temperature of these fumaroles as part of MVO’s continuing efforts to monitoring the activity of the Soufriere Hills Volcano.
Dr Stinton also took some direct measurements in the fumaroles with a thermocouple and noted temperatures of 94.8 to 95.1 °C, which are in line with the last set of temperatures measured in January 2019.
For safety reasons, Dr Stinton can be seen wearing a hot suit, hard hat, gas mask and heat-resistant gloves to protect him from the heat and the gases being emitted by the fumaroles.
