Extreme Geohazards – what are they?
In December 2004, we all learned one Japanese word; tsunami  (津波, lit. "harbor wave"). Japan has seen a number of tsunamis through out times, situated right there on the Ring of Fire, and when the Sumatran earthquake hit the ocean floor in the Indian ocean in 2004 creating the monster waves killing some 300 000 people, tsunami became a household Japanese word, included in many languages.

In 2010 volcanic ash from Eyjafjallajökull clouded Europe for days. It opened up a discussion about how science is used in risk management. Europe had just finished its first volcanic ash crisis exercise validating changes and improvements to the volcanic ash contingency plan and procedures, when a new eruption on Iceland, the Grímsvötn volcano beneath the vast Vatnajökull glacier, threatened air travel and ultimately our economy once more just over a year after Eyjafjallajökull.
