During 2010, Christchurch had a 7.1 Richter Scale Eartquake. The earthquake caused liquefaction. Dr Nicol said “The Christchurch experience teaches us that liquefaction might in some cases cause bigger problems for people than movement on the fault itself.”
The 2010 earthquake richter scale was 7.1, but nobody died.
The second earthquake was on the 22nd of February 2011. This earthquake’s richter scale was 6.3. Unlike the earthquake in 2010, this one was worst. One Hundred and eighty-five people were killed, mostly when multi-storied buildings collapsed.
Scientists are using Christchurch earthquakes as an example to learn from it, so they can warn people to make good choices about where they live.
