Plate Tectonic Case Study Portfolio
New Zealand:
Epicentre was 25 miles west of Christchurch and the focus was
shallow at 6 miles
4:35am 4 September 2010
7.1 magnitude
Conservative plate margin Pacific Plate slid past the Australian
Plate in the opposite direction (causing thousands of aftershocks)
September 2010:
Movement of Pacific and Australian plates
Potential seismic lensing (huge amount of energy reflecting off hard basalt rock)
4 September 2010 until 4 September 2011, there were around 9,000 aftershocks and
As many as 100 faults have been identified around New Zealand (some as close to 12 miles
from central Christchurch)
On Boxing Day (26 December 2010) there was a large aftershock of the September
earthquake of magnitude 4.9 and 7 miles deep
Primary ­
One person died of a heart attack and 2 were seriously injured
Brick chimneys toppled through tile roofs
One of the few cases of serious injury was caused by a falling chimney
Christchurch hospital forced to used emergency generators
Historic stone churches were badly damaged, although both the Anglican and Catholic
cathedrals survived with minor cracking
Secondary ­
Schools were closed for about two weeks after the earthquake, due to damage to school
land and buildings, lack of power or water, transport difficulties and frequent aftershocks
Soil liquefaction caused flooding, damaged buried pipes and building foundations
Warnings issues not to drink running water because of contamination from broken sewage
