Events
On 18 March 2007, the tephra dam collapsed, causing a "medium" sized lahar which flowed down the mountain and into the Whangaehu River. The ERLAWS system activated at 10:47am and worked exactly as planned. Scientists estimate that 1.29 million cubic metres (1.29 billion litres) of sulphur and water went down the Whangaehu Valley, leaving 8.9 million cubic meters in the crater lake. This lahar was at least 50% larger than the 1953 lahar that caused the Tangiwai disaster.

Famous quotes containing the word events:
“Since events are not metaphors, the literal-minded have a certain advantage in dealing with them.”
—Mason Cooley (b. 1927)
“The system was breaking down. The one who had wandered alone past so many happenings and events began to feel, backing up along the primal vein that led to his center, the beginning of hiccup that would, if left to gather, explode the center to the extremities of life, the suburbs through which one makes one’s way to where the country is.”
—John Ashbery (b. 1927)
“The prime lesson the social sciences can learn from the natural sciences is just this: that it is necessary to press on to find the positive conditions under which desired events take place, and that these can be just as scientifically investigated as can instances of negative correlation. This problem is beyond relativity.”
—Ruth Benedict (1887–1948)
