Unreinforced masonry (URM) buildings have repeatedly been shown to perform poorly in large magnitude earthquakes, with both New Zealand and Australia having a history of past earthquakes that have resulted in fatalities due to collapsed URM buildings. A comparison is presented here of the URM building stock and the seismic vulnerability of Christchurch and Adelaide in order to demonstrate the relevance to Australian cities of observations in Christchurch resulting from the 2010/2011 Canterbury earthquake swarm. It is shown that the materials, architecture and hence earthquake strength of URM buildings in both countries is comparable and that Adelaide and other cities of Australia have seismic vulnerability sufficient to cause major damage to their URM buildings should a design level earthquake occur. Such an earthquake is expected to cause major building damage, and fatalities should be expected.
Damage to the Community of the Sacred Name building on Barbadoes Street. Masonry from one of the building's gables has collapsed onto the footpath.

The damaged Cranmer Courts on the corner of Kilmore and Montreal Streets. The corner of the building has crumbled onto the street, which is now littered with broken masonry. Wire fencing placed around the building after the 4 September 2010 earthquake has managed to keep the debris away from the road.
A photograph of the earthquake damage to the Canterbury Provincial Chambers on Durham Street. The top of one of the chambers has crumbled and the masonry has fallen onto the footpath. Scaffolding which was erected after the 4 September 2010 earthquake has also fallen. Wire fences have been placed around the building as a cordon.
A photograph of the earthquake damage to the former Canterbury Public Library on the corner of Hereford Street and Cambridge Terrace. The bricks in the corner of the building have crumbled and masonry can be seen on the footpath below. Wire fences have been placed around the building as a cordon.

A photograph of the earthquake damage to Avonmore House on Hereford Street. Sections of the walls have crumbled, spilling bricks and masonry onto the footpath and street below. Many of the windows have warped, breaking the glass. USAR codes have been spray-painted on one of the columns.
Damage to the A and T Burt building on Ferry Road in Woolston. Masonry has collapsed from the top section of the building's front wall, exposing its ceiling.
Damage to the Music Centre of Christchurch building on Barbadoes Street. Tarpaulins have been used to weather proof gaps in the building's gables from where masonry has fallen.

A photograph of the earthquake damage to the Cathedral of the Blessed Sacrament on Barbadoes Street. The tower on the right has crumbled, and the masonry has fallen to the pavement below. A car has been crushed by the fallen rubble. Windows in the tower behind are broken.
A photograph of the earthquake damage to a building on Lichfield Street. Masonry from the top section of the building has broken away and spilled onto the footpath below. A red sticker has been placed on the door, indicating that the building is unsafe to enter. USAR codes have been spray-painted on the column and window to the right.
In the early morning of 4th September 2010 the region of Canterbury, New Zealand, was subjected to a magnitude 7.1 earthquake. The epicentre was located near the town of Darfield, 40 km west of the city of Christchurch. This was the country’s most damaging earthquake since the 1931 Hawke’s Bay earthquake (GeoNet, 2010). Since 4th September 2010 the region has been subjected to thousands of aftershocks, including several more damaging events such as a magnitude 6.3 aftershock on 22nd February 2011. Although of a smaller magnitude, the earthquake on 22nd February produced peak ground accelerations in the Christchurch region three times greater than the 4th September earthquake and in some cases shaking intensities greater than twice the design level (GeoNet, 2011; IPENZ, 2011). While in September 2010 most earthquake shaking damage was limited to unreinforced masonry (URM) buildings, in February all types of buildings sustained damage. Temporary shoring and strengthening techniques applied to buildings following the Darfield earthquake were tested in February 2011. In addition, two large aftershocks occurred on 13th June 2011 (magnitudes 5.7 and 6.2), further damaging many already weakened structures. The damage to unreinforced and retrofitted clay brick masonry buildings in the 4th September 2010 Darfield earthquake has already been reported by Ingham and Griffith (2011) and Dizhur et al. (2010b). A brief review of damage from the 22nd February 2011 earthquake is presented here
