Increased geothermal activity observed at Iceland’s Geysir Geothermal Area
The Icelandic Met Office (IMO) is reporting increased geothermal activity in the Geysir Geothermal Area since Saturday, October 19, 2024. The reason for the changes observed remains unclear 3 days after the activity increased.

Increased activity in several hot springs at Iceland’s Geysir Geothermal Area has been observed since October 19. The Met Office, along with the Environmental Agency and Civil Defense, is investigating the cause, noting that real-time monitoring systems like GPS, seismometers, and satellite images are yet to explain the changes.
The Geysir Geothermal Area is a geothermal field located in the Haukadalur Valley in southwestern Iceland. It is known for its hot springs, geysers, and other geothermal features. The area gets its name from “Geysir,” one of the world’s most famous geysers, which is the origin of the term “geyser” used to describe such natural hot water eruptions worldwide.
The hot spring named Strokkur is drawing particular attention as it has been having higher steam explosions (up to 30 m / 100 feet), more powerful, and more frequent than usual.
Along with the steam, mud and small stones have been thrown into the air during these eruptions, increasing potential hazards for visitors. However, Geysir has not exhibited any changes in activity.
Specialists from the Environmental Agency, the Met Office, and the Civil Defense met late October 21 (LT) to go over the situation. The situation will continue to be watched and attempts will be made to understand the underlying reasons for the increased activity.
Geothermal areas are highly dynamic and there are always hazards present when visiting areas with boiling water and steam.
The Met Office has issued warnings to visitors, urging them to maintain a safe distance from the hot springs due to the inherent dangers of geothermal areas, particularly in the presence of boiling water and frequent steam explosions.
The geothermal activity in the area, including hot springs, geysers, and steam vents, is the result of underground volcanic activity, but there is no volcano directly in the area.
The nearby volcanic systems, such as Hekla and Katla, are responsible for much of the volcanic activity in the region, but they are not directly connected to the Geysir area. The geothermal activity in the Geysir Geothermal Area is primarily thought to be caused by heat from deep within the Earth.
