New Zealand Earthquake Spurs Giant Glacier Collapse

On 22 of February, 2011 there was a 6.3 earthquake in New Zealand. This earthquake made the Tasman glacier, located in a lake, break. The earthquake lasted for one minute and had an aftershock a one-minute. Scientists think that the glacier broke because in the past days it had been raining and that made the water level of the lake go up. The increase in the water level made the glacier unstable so when the earthquake came it made the glacier break. The glacier probably had a crack before the earthquake, and this contributed to the loss of a big piece of the glacier. When the block if ice fell in the water, it made many waves, which were about 3 meters tall, and lasted for about 30 minutes.

I found this article interesting because this is something that is happening and it can happen again in another place. I think that is article is important because the global worming is making many glacier brake and know also the earthquakes braking the glacier, that means that in some point we will not have glaciers.

This article makes connections with science because the glaciers are important to science and to our world but people are making them melt with pollution.
