Synonyms of features appear indented below the primary name. In some cases additional feature type, elevation, or location details are provided.

Eruptive History

The Global Volcanism Program is not aware of any Holocene eruptions from Hrómundartindur. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Hrómundartindur page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

Deformation History

There is data available for 1 deformation periods. Expand each entry for additional details.

Deformation during 1993 - 1998 [Variable (uplift / horizontal); Observed by GPS, InSAR]

Start Date: 1993 Stop Date: 1998 Direction: Variable (uplift / horizontal) Method: GPS, InSAR
Magnitude: Unknown Spatial Extent: Unknown Latitude: Unknown Longitude: Unknown

Remarks: Uplift near the Hengill triple junction is associated with an earthquake swarm.

Figure (see Caption)

Observed interferograms of the Hengill area for four different time intervals. The time interval appears in the upper right corner of each panel; the orbit numbers appear at lower left; and the altitude of ambiguity ha appears at lower right. One fringe represents 28 mm of range change. Two concentric fringes are visible in the 4-year interferogram (d) indicating at least 6 cm of uplift between August 1993 and August 1997.

Steam rises from a hot pool in the Olkeduháls geothermal area of the Hrómundartindur volcanic system, which lies south of Thingvallavatn lake. The Olkeduháls geothermal field contains numerous hot springs, mud pools, fumaroles, and mineral warm springs. The Hengill volcanic system forms the ridge on the skyline immediately west of the Hrómundartindur volcanic system.

A group of volcanologists on a field trip observe activity at the Olkeduháls geothermal field of the Hrómundartindur volcanic system. This small volcanic system lies at a ridge-ridge-transform triple junction at the eastern end of the Reykjanes Peninsula, where the west Iceland volcanic zone changes direction from approximately W-E to SW-NE. The latest eruptions at Hrómundartindur took place at the end of the latest glacial period, but Hrómundartindur displays vigorous geothermal activity at the Olkeduháls geothermal field.
