“…The first earthquake sequence initiated three other significant earthquakes close to the city of Christchurch culminating in an aftershock which was the second major earthquake, measuring 6.3 on the Richter scale, and which struck at 12:51 pm on February 22, 2011. The location of the second major quake was within 5 km south-east of Christchurch, at a shallow focal depth of 5 km (Wu et al, 2014). This second quake produced damage labeled as destructive by GeoNet (the builder and operator of modern geological hazard monitoring systems in New Zealand); unreinforced masonry buildings were severely damaged with liquefaction occurring in many parts of the eastern suburbs rendering entire neighbourhoods completely uninhabitable (Buchanan, Carradine, Beattie, & Morris, 2011;Bull, 2013).…”
