I looked out onto Cathedral Square and appreciated the beauty of the city. We took the boys for a ride on the hop on/hop off tram, watched people play chess in the square, and felt our beings relax into holiday mode. Cathedral Square and the Christchurch CBD was a highlight – so relaxed for a CBD, and beautiful, despite the still present damage to buildings from the September quake.
The Christchurch Cathedral was majestic; its stained glass windows glowed. Christchurch City Centre Demolitions Speeding Up. Last updated 05:00 29/09/2012 The demolition of central Christchurch continues, with more than 800 buildings already razed and many more still to come down.
A total of 1350 buildings have been partly or fully demolished in the city centre since the September 2010 earthquake, including 307 buildings taken down by Civil Defence. Demolition is underway on 58 buildings, Canterbury Earthquake Recovery Authority (Cera) figures show. Demolition is slated for Te Waipounamu House in Hereford St, Majestic House in Manchester St, the ANZ building in Colombo St and Landsborough House in Durham St. Demolition is under way on the PricewaterhouseCoopers building, the Farmers parking building, the Holiday Inn, the Westpac building and Clarendon Tower.
Ngai Tahu's former headquarters in Hereford St, Te Waipounamu House, is owned by the Pandey family, which owns hotels around New Zealand. Majestic House is inside the eastern frame and the land will be acquired by Cera. "It is like a blank canvas now. PACIFIC RING OF FIRE. PACIFIC RING OF FIRE. Pacific Ring of Fire The Pacific Ring of Fire (or just The Ring of Fire) is an area where large numbers of earthquakes and volcanic eruptions occur in the basin of the Pacific Ocean.
In a 40,000 km (25,000 mi) horseshoe shape, it is associated with a nearly continuous series of oceanic trenches, volcanic arcs, and volcanic belts and/or plate movements. The Ring of Fire has 452 volcanoes and is home to over 75% of the world's active and dormant volcanoes. 320-7314870030312599674-Yr_9_Earth_Science_Pop_Quiz. Plate Tectonics.

There are a number of excellent sites dealing with the modern theory of plate tectonics. The Paleomap project at the University of Texas at Arlington.Paleogeography Through Geologic Time by Ron Blakey at Northern Arizona University. Finally, it seems appropriate to mention the Alfred Wegener Institute, the German national research center for polar and marine research, carrying on Wegener's tradition of interdisciplinary earth science.

Volcanic eruption gives birth to 'new island' in Japan. Supervolcano eruption mystery solved. 6 January 2014Last updated at 08:28 ET By James Morgan Science reporter, BBC News If the Yellowstone supervolcano erupted the impact would be catastrophic Scientists have made a breakthrough in their efforts to understand what causes so-called supervolcanoes to erupt.
Supervolcanoes are capable of eruptions thousands of times larger than normal outpourings. It was thought that an external trigger, such as an earthquake, was needed to bring about a giant blast. But tests at the European Synchrotron Radiation Facility in Grenoble show the sheer volume of liquid magma is enough to cause a catastrophic super-eruption. Details of the research by a Swiss team appear in Nature Geoscience. Simulating the intense heat and pressure inside these "sleeping giants" could help predict a future disaster. Lead author Wim Malfait, of ETH Zurich, said: "We knew the clock was ticking but we didn't know how fast: what would it take to trigger a super-eruption?
