IS ALL HELL ABOUT TO BREAK LOOSE?
Magma chamber causing earthquakes
“Scientists have found a startling reason for the thousands of quakes that have swarmed around a tiny eastern Bay of Plenty settlement over recent years – a huge magma chamber lying just a few kilometres beneath it.” http://www.nzherald.co.nz/nz/news/article.cfm?c_id=1&objectid=11650441
Thousand earthquakes had occurred the town of Matata between 2004 and 2011, and a 20km-square area of land around the town has been pushed up by about 40cm since 1950.
“Using a model based on modern GPS and satellite radar data, along with decades of survey records, scientists have concluded a magma body lies about 9km below the surface – and since 1950 its volume had grown by the equivalent of 80,000 Olympic swimming pools.” [Volume of an Olympic swimming pool is 2,500 cubic meters.]
GNS Science employees insist the presence of such enormous amount of magma does not mean an eruption could be imminent, nor had it changed the volcanic hazard of the Bay of Plenty region.
[However, they have failed to explain what might happen if the rate of inflation increases, or the uplift continues even at its current rate, an informed source has noted.]
“Our modelling points to the presence of a magma chamber in an area where there has been no active volcanism for about 400,000 years,” said GNS Science satellite image specialist Dr Ian Hamling.
OK! But what’s the significance of the sizeable ground uplift in recent years?
What are the probabilities of a catastrophic eruption in the Bay of Plenty region in the next 1,000 years, 100 years, 10 years, or indeed 100 days?
We have the right to know. If GNS Science people don’t have the answer, they should come clean and say so now.
