It's only really near-fault earthquakes that actually cause rockfall" The Press 3Oct14 Wellington's fault find prompts grim warning "A previously unknown fault zone with the potential to severely damage new zealand's capital has prompted fresh calls for vigilance. The aotea fault has lain beneath Wellington Harbour giving no hint of the havoc it could unleash every few thousand years. 'Ultimately, the first response isn't the ambulance, emergency services and all that, the first response is your neighbours'. Newly-found fault was capable of producing a shake of up to magnitude.3.1. But how often it ruptured could only be narrowed down to every 'several thousand' years. The last big shake scientists could spot in its geological record was 6200 years ago." The Press 9Oct14 Groundwater changes may warn of big quakes "certain chemical signals rapidly increased in underground water weeks before large earthquakes hit Iceland. Stress building up along the fault-line before a quake pulled and distorted the rock, exposing new surfaces to the groundwater. Previously untouched rock would then leach its calcium, sodium and silicon into the water, giving the signature spikes" The Press 18Oct14 Megaquake could hit central New zealand "in the past 1000 years two subduction quakes of at least magnitude 7 occurred - one between about.

Lava flows are dated to the end-Triassic extinction, 201.4 million years ago, which wiped out 50 of tetrapods (four-limbed animals) on land, 50 of terrestrial plants and 20 of marine families. 'flood basalts' form a giant geological entity known as the central Atlantic brief Magmatic Province (Camp). This was formed during the break up of the 'supercontinent' known as Pangaea, causing lava to pour out on to the earth's surface for some 700,000 years.

About the size of domestic cats. At most a kilogram or two. Walked on four legs. The footprints date to just two million years after the end-Permian mass extinction - the worst mass extinction in the history of the planet. More than 90 of all life on Earth was wiped out due to massive volcanic eruptions, sudden global warming and the stagnation of the oceans. Scientists had thought that dinosaurs emerged 15 to 20 million years after the mass extinction, when the planet had become more habitable. But the new footprints suggest that the rise of dinosaurs was intimately related to the devastating extinction event" news 5Oct10 dinosaurs' dominance 'helped by mass volcanism' "volcanic eruptions changed the climate, causing a mass extinction that wiped out the dinosaurs' main competitors.

Magma_chamber "large underground pool of molten rock found beneath the surface of the earth. Under great pressure, and given enough time, illustration that pressure can gradually fracture the rock around it creating outlets for the magma. If it finds a way to the surface, then the result will be a volcanic eruption; consequently many volcanoes are situated over magma chambers. Hard to detect, and most of the known ones are therefore close to the surface of the earth, commonly new between 1 km and 10 km under the surface. In geological terms this is extremely close to the surface, although in human terms it is considerably deep underground. Magma rises through fractures from beneath the crust because it is less dense than the surrounding rock. When the magma cannot find a path upwards it pools into a magma chamber.
As more magma rises up below it, the pressure in the chamber grows" wikipedia magma east Australia hotspot hotspot (geology) volcano safety warning Signs m/facts new Magma layer found deep in Earth's Mantle? Etc Any new magma chamber local to the south Island would probably appear south of this Pacific Plate land mass, where its subductive force is not restrained by the australian plate at the southern Alps - west of foveuax Strait, behind the deep quake fjordland. It is the magma chambers more active around the north Island, under Australian Plate subductive force, that present true killer risk.

Also as a result of faulting, outflow from warm springs at the northern end of Rapaki bay had increased. There were six sulphurous springs of up to 20 degrees Celsius within about 60 metres of the beach and oriented west-east, he said. 'The distinct sulphurous smell associated with these hot springs and other outflows is due to water coming up from depth, much like hanmer Springs, and not to do with magma-water interactions The Press 11Sept Underground water shaken up by fault "Some farmers say their paddocks. Ecan acting director of investigations and monitoring, tim davie, said the quake could have a lasting impact, with some wells broken. No lasting large-scale changes were expected to aquifers. Sulphurous smells were being reported around the region but it was unlikely they were all related to new springs, he said.
