On the other hand, that moderate quake was shallow, at a depth of 5 km (3.1 mi).davenn said:The M 6.3 quake that wrecked Christchurch, NZ in Feb. 2011 had a peak ground accel. of 220.3% g pretty much above the focus.
there was a soft ground location some 10 km to the north ( just east of the city centre) that hit 188.7% g

The major quake in Bougainville, PNG was caused by tectonic plates shifting and releasing energy along a fault line. This is a common occurrence in areas with high levels of tectonic activity, such as the Pacific Ring of Fire.
The magnitude of the major quake in Bougainville, PNG was initially reported as a 7.5, but was later downgraded to a 7.2 by the US Geological Survey. This makes it a strong earthquake, but not considered to be a major quake.
At this time, there have not been any reports of casualties from the major quake in Bougainville, PNG. However, there have been reports of damage to buildings and infrastructure in the surrounding area.
According to the Pacific Tsunami Warning Center, there is a small possibility of a local tsunami in the area near the epicenter of the major quake in Bougainville, PNG. However, this risk is considered to be low and there is no current tsunami warning in effect.
Bougainville, PNG is located in a highly active seismic zone and is prone to earthquakes. Major quakes, with a magnitude of 7.0 or higher, occur in this region approximately every 5-10 years.
