Te Wairo Buried!

Extracts from this document...

Introduction

the 1860s, then repopulated a few years later as the staging post for travellers to the Pink and White Terraces. The eruption of Mount Tarawera was the most recent of numerous volcanic events in the Rotorua region over the last 20,000 years. It destroyed the Terraces and buried Te Wairoa and two smaller villages under hot, heavy ash and mud. More than 150 lives were lost. A meandering pathway, set among trees and meadows beside the Te Wairoa Stream, connects the Buried Village's excavated dwellings. A museum introduces visitors to the fascinating drama and brings history alive today. Violent and unexpected, the eruption of the Tarawera volcano during the early hours of June 10, 1886, was New Zealand's greatest natural disaster. At 1.40 am, the supposedly extinct volcano, Mount Tarawera exploded. The three domes on this now flat-topped volcano blew and demolished one side of the mountain. Over the next six hours several eruptions occurred and a 17 kilometre wound of craters and deep, elongated pits was created. The eruption ripped away the bed of the nearby Lake Rotomahana burying Te Wairoa and other nearby villages with mud, rock and ash. ...read more.

Maori whare Excavated to original floor level, this site displays a fireplace and an assortment of relics recovered when digging first began in 1931. Flour Mill Parts of the mill, including millstones and gears. Wheat was grown in the Te Wairoa Valley and the stream was diverted to drive the mill's waterwheel. Aspen poplars Among the tallest in New Zealand, these trees grew from fence posts that formed a property boundary before the eruption. Tops of posts can be seen above ground. Barman's house Plates and household items were found here, along with bottles, tools and implements, and a well preserved fireplace and cast iron bed frame. Stone Chimney On the hill in the bush, across Tarawera Road, are the remains of the home of one of the two local Maori leaders at Te Wairoa. Faloona's Store One of two general stores in Te Wairoa selling everything from tobacco to toothbrushes, this was apparently looted in the days following the eruption. Rotomahana Hotel This two storey wooden building collapsed six hours after the eruption started, killing an English tourist. Travellers stayed here en route to the terraces. ...read more.

Conclusion

Indo-Australian and Eurasian plates, eg. Himalayas C Conservative Margins Two plates move sideways past each other-land is neither formed nor destroyed Can be violent earthquake activity (no volcanic activity) Pacific and North American plates, eg. San Andreas, California The eruption of Mount Tarawera was triggered by destructive margins, these occur where plates consisting of oceanic crust move towards plates of continental crust. For example, to the west of South America, the Nazca Plate (oceanic crust) is moving towards the American Plate (continental crust). Where they meet, the Nazca Plate is forced downwards to form a subduction zone and an associated deep-sea trench (the Peru-Chile trench). The increase in pressure, as the plate is forced upwards, can trigger severe earthquakes. As the oceanic crust continues to descend, it melts, partly due to heat resulting from friction caused by contact with the American Plate and partly due to the increase in temperature as it re-enters the mantle. Some of the newly formed magma, being lighter than the mantle, rises to the surface to form volcanoes (eg. Chimborazo and Cotopaxi) and a long chain of fold mountains (the Andes). Sometimes, at destructive margins, the magma rises offshore to form island arcs such as the West Indies, Japan and off the south coast of Alaska, the Aleutian Islands.
