Micro - electro - mechanical system (MEMS) based accelerometers are now frequently used in many different parts of our day - to - day lives. It is also increasingly being used for structural testing applications. Researchers have had res ervation of using these devices as they are relatively untested, but now with the wider adoption, it provides a much cheaper and more versatile tool for structural engineering researchers. A number of damaged buildings in the Christchurch Central Business District (CBD) were instrumented with a number of low - cost MEMS accelerometers after the major Christchurch earthquakes. The accelerometers captured extremely high quality building response data as the buildings experienced thousands of aftershocks. This d ata set was amongst one of only a handful of data set s available around the world which provides building response data subjected to real ground motion. Furthermore, due to technological advances, a much larger than usual number of accelerometers has been deployed making the data set one of the most comprehensive available. This data set is utilised to extract modal parameters of the buildings. This paper summarises the operating requirements and preference for using such accelerometers for experimental mod al analysis. The challenges for adapting MEMS based devices for successful modal parameters identification are also discussed.
A photograph of the earthquake damage to a dairy on the corner of Barbadoes Street and Edgeware Road. The second storey of the dairy has collapsed, and the bricks have fallen onto the footpath, taking the awning with them. Police tape and road cones have been placed around the building as a cordon.
A photograph of the rebuilt Blackwell's Department Store on the corner of Williams Street and Raven Quay in Kaiapoi. The department store was rebuilt after the previous building was damaged in the 2010 and 2011 Canterbury earthquakes. This photograph was modelled off an image taken by BeckerFraserPhotos in September 2010.
A view looking south down Durham Street. Two fire engines are driving north, and a pair of construction workers are walking up the road. Behind them is the damaged Provincial Council Legislative Chambers. The building's walls and roof have collapsed, as has the scaffolding which was erected to repair it after the 4 September 2010 earthquake.
Damage to the Visitors Centre in Kaiapoi, after the September 4th earthquake. The foundations have lifted at the back of the building, giving it a forward lean. Cables have been attached to the balcony over the walkway and braced to posts cemented into the ground. This is to stop the building from slumping further.

A sign on a tent set up in the Arts car park at the University of Canterbury after the 22 February 2011 earthquake. The tents were used as temporary lecture rooms while the buildings were being checked for damage. The sign reads, "Clyde 4, ANTH 102 in E338 Drawing Room Mon 11Am, 155 Seat".
A photograph of the earthquake damage to a group of shops on Manchester Street. The closest shop has collapsed and the floor of the upper storey is hanging out of the side of the shop. To the left, the outer walls of the top storeys of the shops have collapsed, the bricks spilling onto the street.
A photograph of the back of two earthquake-damaged houses on Gloucester Street. The side wall of the house to the right has partially collapsed and the bricks have spilled onto the property to the left. Plastic sheeting has been placed over the roof and the top of the wall to protect against the weather.
A photograph of the earthquake damage to the Registry Building on the corner of Montreal and Worcester Streets. Masonry around the gable has collapsed onto the footpath below. Steel bracing has been used to hold up the remaining masonry. Wire fencing has been placed around the building as a cordon.
A photograph of members of the Wellington Emergency Management Office Emergency Response Team and the Red Cross working on High and Manchester Streets. On both sides of the street there are piles of rubble from the earthquake-damaged buildings. Several excavators have been parked in a line along the street.

A photograph of a member of the New Zealand Army talking to a police officer on the corner of Colombo and Wordsworth Street. In the background there is a block of earthquake-damaged shops. Sections of the shops' walls have collapsed and the rubble has spilled onto the road and footpath.
A photograph of the earthquake-damaged Cathedral of the Blessed Sacrament on Barbadoes Street. Rubble from the collapsed tower is lying on the ground in front. A car has been crushed under this rubble. Wire fencing, shipping containers, and road cones have been placed around the building as a cordon.

Many large-scale earthquakes all over the world have highlighted the impact of soil liquefaction to the built environment, but the scale of liquefaction-induced damage experienced in Christchurch and surrounding areas following the 2010-2011 Canterbury earthquake sequence (CES) was unparalleled, especially in terms of impact to an urban area. The short time interval between the large earthquakes presented a very rare occasion to examine liquefaction mechanism in natural deposits. The re-liquefaction experienced by the city highlighted the high liquefaction susceptibility of soil deposits in Christchurch, and presented a very challenging problem not only to the local residents but to the geotechnical engineering profession. This paper summarises the lessons learned from CES, and the impacts of the observations made to the current practice of liquefaction assessment and mitigation.
