part of the central highlands of Iceland. It has a lake in its smaller caldera, which resulted from an 1875 eruption. It is the youngest of such formations on Earth.
As a consequence of the rockslide, a small tsunami traversed the lake and into Víti, a smaller explosion crater on the northeastern shore of Öskjuvatn. Tremors were detected for 20 minutes on seismometers in the area. A witness saw

triggered a tsunami in the lake that washed up on the lakeshores all around the lake, reaching up to 20–30 m and even higher in places. The wave travelled farthest around 400 m into the flatland SE of the crater Víti.
It was fortunate that the rockslide occurred late at night and nobody was close to the water, otherwise it would have been extremely hazardous. A few hours earlier, tens of people were

The results of the collective research were published in 2009 in a book called The design of avalanche protection dams - Recent practical and theoretical developments.
