New Zealand’s seven Crown Research Institutes (CRIs) have created the National Environmental Data Centre (NEDC) website to make the environmental information held by CRIs more accessible to all New Zealanders.
Ten-thousand miles away in England, Simon Proud, a satellite data researcher at the University of Oxford, began to monitor the twitching volcano using an array of satellites.Then, early in the morning on January 14 local Tongan time, a 12-mile-high plume of ash pierced the sky.
The following video shows glass beads being tipped down aerated ramps into water to mimic what happens when pyroclastic flows hurtle down the sides of erupting volcanoes: .
This destabilization is being driven by climate change: Tsunamis are becoming more likely in Alaska as hillsides, formerly reinforced by glaciers and solidly frozen ground, loosen their hold on once-stable slopes.Climate change makes land more unstable and increases the risk of landslide-caused tsunamis.
NIWA hazards analyst Ryan Paulik, who led the assessment, says overall 430,000 people – or nine per cent of the population – live in the zones of which 170,000 are in red and orange zones.
For the first time the Whakatipu lake floor will be mapped to build a picture of the potential for local tsunami hazards in the future.
Melting glaciers could be triggering a ripple effect of natural disasters that culminates in massive tsunamis, according to new research. This problem is likely to be exacerbated along the icy coastlines of Greenland, Patagonia and Norway, where huge chunks of rock smashing into the water can create towering waves.
