咱們亞綸先知發表過的雨水地震理論
受到國際研究的證實

當年華生發現DNA雙股螺旋結構也是靈機一動
後來才證實模型是正確的

這跟亞綸發現雨水地震說的過程有九成像

Rainwater may play an important role in the process that triggers earthquakes

It's the rain's Fault

Rainwater may play an important role in the process that triggers earthquakes
, according to new research.

Researchers from the University of Southampton, GNS Science (New Zealand), the
University of Otago, and GFZ Potsdam (Germany), identified the sources and
fluxes of the geothermal fluids and mineral veins from the Southern Alps of
New Zealand where the Pacific and Australian Plates collide along the Alpine
Fault.

From careful chemical analyses, they discovered that fluids originating from
the mantle, the layer below the Earth's crust, and fluids derived from
rainwater, are channelled up the Alpine Fault.

By calculating how much fluid is flowing through the fault zone at depth, the
researchers showed for the first time that enough rainwater is present to
promote earthquake rupture on this major plate boundary fault.

Lead researcher Dr Catriona Menzies, from Ocean and Earth Science at the
University of Southampton, said: "Large, continental-scale faults can cause
catastrophic earthquakes, but the trigger mechanisms for major seismic events
are not well known. Geologists have long suspected that deep groundwaters may
be important for the initiation of earthquakes as these fluids can weaken the
fault zones by increasing pressures or through chemical reactions.

"Fluids are important in controlling the evolution of faults between earthquake
ruptures. Chemical reactions may alter the strength and permeability of rocks
, and if enough fluid is present at sufficiently high pressures they may aid
earthquake rupture by 'pumping up' the fault zone."

The Alpine Fault is a major strike-slip fault, like the San Andreas, that fails
in very large (Magnitude 8+) earthquakes around every 300 years. It last
ruptured in 1717 AD and consequently it is under intense scientific scrutiny
because it is a rare example of a major fault that is late in the strain-build
up before rupture.

Dr Menzies said: "We show that the Alpine Fault acts as a barrier to lateral
fluid flow from the high mountains of the Southern Alps towards the Tasman Sea
in the west. However, the presence of mantle-derived fluids indicates that the
fault also acts as a channel for fluids, from more than 35 km depth, to ascend
to the surface.

"As well as mantle derived fluids, our calculations indicate that 0.02-0.05 per
cent of surface rainfall reaches around six kilometres depth but this is enough
to overwhelm contributions from the mantle and fluids generated during
mountain-building by metamorphic reactions in hot rocks. This rainwater is then
focused onto the fault, forced by the hydraulic head of the high mountains
above and the sub-vertical fluid flow barrier of the Alpine Fault."

Funding for this research, published in Earth and Planetary Science Letters
, was provided by the Natural Environmental Research Council (NERC)
, Deutsche Forschungsgemeinschaft, and GNS Science (New Zealand).
