Earthquakes

At 12:51 p.m. on Tuesday the 22nd of February, 2011 Canterbury was again shaken by an earthquake. This time the magnitude was 6.3 but it was at a depth of 5 kilometres. Unfortunately there was significant loss of life and major destruction in the Central Business District.
John Key, New Zealand's Prime Minister called for 2 minutes silence at 12:51 on March the 1st, 7 days later. At Summerland Primary we observed this time of national silence to honour those who lost their lives and think of the people of Canterbury who were affected.
Liquefaction caused much of the damage. These videos show what liquefaction is.



At 4:35 a.m. on Saturday the 4th of September, 2010 Christchurch was rocked by an earthquake measuring 7.1 on the Richter scale.
