Since Friday the Cook Strait in New Zealand has been experiencing a series of moderate but shallow earthquakes.\u00a0 The map below, from Geonet<\/a>, shows the locations of the various events:<\/p>\n

The largest event, which occurred at 5:09 pm yesterday (Sunday), was a magnitude 6.5 earthquake at a depth of 13 km<\/a>.\u00a0 This generated a large number of felt reports across central New Zealand and beyond on the Geonet website<\/a>:<\/p>\n

Of course the large number of felt reports in the southern part of North Island reflects the presence of the City of Wellington, which is located on a major fault system and is considered to be vulnerable to\u00a0 a large earthquake event.\u00a0 Fortunately, this was a small earthquake, and it was some distance away, but nonetheless the city suffered some damage.\u00a0 There is a good gallery of images on the stuff.co.nz website<\/a>, some of which show damage from landslides and liquefaction failures.\u00a0 Probably the best of these is this pair of images taken by French tourist Luca Zappula\u00a0 of the White Bluffs from the Wairau Bar.\u00a0 The left image was taken just before the earthquake, the right just after.\u00a0 The dust indicates a slope failure has occurred:<\/p>\n

There also seems to have been some damage from liquefaction failures of the harbour area, as these images from Mike Pryce show.<\/p>\n

Meanwhile the M=6.6 earthquake in Minxian and Zhangxian counties in Gansi Province this morning occurred in terrain that is landslide prone.\u00a0 Earthquake-reports<\/a> is currently indicating 56 deaths, 14 missing and over 400 injured.\u00a0\u00a0 Given that this earthquake has occurred in the rainy season it would be unsurprising to find that landslides have been a problem here, but at the moment even Xinhua<\/a> has little information.<\/p>\n","protected":false},"excerpt":{"rendered":"
