Óþerrishola (Otherrishola)

In detail
This fascinating landmarks is located in Haukadalur geothermal area.
Atmospheric pressure means much to some
There are people who feel well about the changes in atmospheric pressure – they might complain about hurting bones, headaches before the rain.
Óþerrishola feels this as well. Geyser seems to be "happy" about the falling pressure – the silent spring often turns into a fervent geyser!
This action is caused by the decreased air pressure, which now allows the geyser to erupt. As the air pressure increases, the geyser becomes stable again.

Wonders of Iceland
Iceland is very rich with peculiar natural landmarks and the island contains also interesting cultural landmarks. The highlights of Iceland are the magnificent waterfalls as well as geysers and other geothermal features.
Geysers
Hasty hydrogeologists would say: geysers are thermodynamically and hydrodynamically unstable hot springs. “Normal” people would say – geysers are hot springs that at more or less regular intervals shoot up a fountain of boiling water and steam. Sometimes these fountains are even 100 m tall… or even 450 m!
