Imaggeo on Mondays: Aoraki & a round-up of the latest New Zealand earthquake news

On Sunday the 13th November, New Zealand’s South Island was struck by a powerful 7.8 M earthquake. Initial analysis by the United States Geological Survey (USGS) indicates that the source of the tremor was faulting on or near the boundary between the Pacific and Australia plates. A tsunami alert (no longer active) was triggered following the earthquake, with risk of tsunami waves along coastal areas. The maximum wave high recorded by a gauge at Kaikoura, 181 km north of Christchurch, was 2.5m, according to

The collision of the two plates is also responsible for the formation of the Alpine Fault, which runs along the western flank of the Southern Alps, (Kā Tiritiri o te Moana). The mountain range runs 500km along the South Island, explains Katrina Sauer on our open access image repository, Imaggeo.  In addition, the Alpine Fault is responsible for the uplift of this impressive mountain range. Sunkissed by a setting sun (pictured above), Aoraki/Mt. Cook is the highest mountain in New Zealand (3,724 m). Katrina took the beautiful picture from Mueller Hut.
