A snow avalanche was released from the Tvísteinahlíð mountain by the health care centre at Engihlíð in Ólafsvík on 19 March 2012. The fracture line of the avalanche was near the top of the slope and extended from the gully to the west of the hillside and into supporting structures that have been installed as protection measures to reduce avalanche danger in the settlement

The vertical displacement (m) was monitored by near real time presentation of data from a GPS station, mounted in the middle of the caldera. The elevation above sea level, top left, refers to the zero value on the y-axis, while such value top right shows the current position of the station (m a.s.l.).

The IMO along with the University of Iceland, the National Power Company Landsvirkjun and the National Power Transmission Company Landsnet, participate in ICEWIND, a Nordic research project on wind energy in cold areas funded by the Top-Level Research (TRI) initiative. The project started in 2010 and runs until 2014.
Nordic partners include

at the University of Iceland, have participated in the Nordic glaciological research project SVALI - Stability and Variations of Arctic Land Ice.
The project is part of the Top-level Research Initiative (TRI) and runs until 2015. All major institutions and universities in the Nordic countries with active glaciological research take part in in the project.
