There are no changes to geothermal activity at Askja volcano, according to preliminary results from a recent research trip conducted by the Icelandic Met Office. The land at Askja has risen 70 cm over the past two years, indicating that some 20 million cubic metres of magma are collecting under the volcano’s surface. An uncertainty phase has been in effect at the site of the remote highland volcano since September 2021.
Eruption on the way?
Volcanologists in Iceland have been predicting that Askja is preparing for an eruption in the near future. While uplift (land rise) has been occurring at the site for around two years, this summer local rangers reported that the temperature of the site’s geothermal lake Víti had risen. A plume of steam was also reportedly sighted at Askja this summer.
Plume of steam was likely dust
A group of scientists from the Icelandic Met Association led by Dr. Melissa Anne Pfeffer and Dr. Michelle Parks made a trip to Askja recently to collect data at the site, including gas and water samples. The preliminary results show no changes in gas or water from previous years, though the samples are being analysed futher at this time. There are no visible changes in the landscape and measurements of temperature and acidity do not indicate chanes in the geothermal activity around Askja and Víti geothermal lake. The report of a plume of steam seen at the site on August 12 has been interpreted as dust from a rock fall on the steep slopes of the caldera.
Askja is a volcano situated in Iceland’s central highland region. Its last eruption occurred in 1961 and gave clear warning in the form of strong earthquakes and a significant rise in geothermal temperatures. No such signs have yet occurred at the site. Tourism operators have nevertheless called for improved telecommunications at the site in case of an eruption.
