Damaged Buildings in Wellington

Nearly 50 earthquake-damaged buildings in Wellington have been inspected by engineers, with some likely to be closed for weeks or longer, and one may require demolition. Yesterday people were asked to stay away from the CBD after several multi-storey buildings were damaged, and glass fell into streets on Monday.

Potential for Future Damaging Earthquakes in New Zealand

Geonet and GNS Science have developed a set of maps of probability of damaging shaking for a series of three MMI intensity levels in the next 30 days.  Figure 1a shows the map for MMI VI, which corresponds to a peak ground acceleration of about 12%g, and is expected to cause structural damage to a few weak buildings.   Large increases in earthquake probability are confined to the South Island.
