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:
“Man is a stream whose source is hidden. Our being is descending into us from we know not whence. The most exact calculator has no prescience that somewhat incalculable may not balk the very next moment. I am constrained every moment to acknowledge a higher origin for events than the will I call mine.”
—Ralph Waldo Emerson (1803–1882)
“All the events which make the annals of the nations are but the shadows of our private experiences.”
—Henry David Thoreau (1817–1862)
“There are no little events in life, those we think of no consequence may be full of fate, and it is at our own risk if we neglect the acquaintances and opportunities that seem to be casually offered, and of small importance.”
—Amelia E. Barr (1831–1919)
