Major Quake Rattles North Canturbury, New Zealand

New Zealand Earthquake Situation

Residents in the North Canterbury region on the South Island of New Zealand were awakened by a major earthquake just after midnight on Monday morning (11/14). The 14-mile-deep quake, which killed two people, triggered a small tsunami, twenty aftershocks, and tens of thousands of landslides across the region. In the two days since, officials have been assessing the situation as the quake and subsequent aftershocks have caused widespread damage to the region. Early cost estimates of the impact are in the hundreds of millions, if not billions.

Following the initial tremor, four aftershocks over 6.0-magnitude (and another sixteen under 6.0) also rattled the area, helping set off thousands of landslides in the steep and coastal terrain.  The coastal town of Kaikoura, north of the epicenter, seems one of the hardest hit with both roads in and out of town cut off by the moving earth.  Heavy rains Tuesday have also complicated rescue and aid efforts.  The situation has prompted a massive evacuation operation by air and sea for the small coastal city’s 2,000 residents. The latest reports state that some locals (and infamous cows) remain stranded with limited supplies. Several New Zealand Navy ships, as well as a US destroyer, are set to help provide needed supplies as well as allow tourists and others to leave Wednesday morning.

Long Term Impact

Similar to the Christchurch disaster of 2011, New Zealand will undoubtedly feel an economic punch from this week’s events. Countless residents have been displaced and infrastructure and land damages are widespread. At least dozens of homes and businesses in the region have been red- and yellow-taped for structural vulnerability. But, unlike the February 2011 quake, the rural epicenter and comparably miniscule population of the affected areas should ease some of the economic and insurance cost concerns.

The hardest hit areas affected by this week’s disaster total a populous only in the thousands, whereas Christchurch’s population is around 370,000. Economists expect the overall impact on the fast growing economy will be small and nowhere near the 45 billion dollar bill from five years prior. What is certain, however, are negative future impacts on tourism for the beautiful Kaikoura area (see below), which lay in crumbles.
