Not exact matches

The pressure difference could be caused by hot, partially molten rock piled up beneath mid-ocean ridges or beneath the cooling plates diving into the earth at subduction zones, the authors write.
The added mass of this rock and sediment has impeded subduction, ultimately causing stress to build up over time.
Highly destructive earthquakes caused by subduction occur because of excessive friction that develops during the sliding process, resulting in a build - up of stress.
These flows dragged South America westward, causing the continent to collide with the subduction zone and thereby forming the Andes.
For example, the Caribbean coast of northern Colombia resembles a classic subduction zone with the potential for tsunamigenic M > 8 earthquakes at millennial time scales, but the absence of a large earthquake since 1492 is cause for complacency among local populations.
«At the time this thing formed, it was in the middle of a basin that was nowhere near a subduction zone — it was nowhere near the kind of geologic activity that would cause a volcano to form.»
Many people understand the damage that can be caused to structures, roads, bridges and utilities by ground shaking in these long - lasting types of earthquakes, such as the one that's anticipated on the Cascadia Subduction Zone between northern California and British Columbia.
The idea is that series of severe earthquakes within a geologically short period of time cause the rising of the land where one tectonic plate slips beneath another slab of Earth's crust in a process called subduction.
The last major earthquake on the Cascadia Subduction Zone — pinpointed in time because it caused a tsunami that raced all the way across the Pacific Ocean to Japan — occurred in January, 1700, more than 315 years ago.
It used measurements from 195 core samples containing submarine landslide deposits caused by subduction zone earthquakes, instead of only about a dozen such samples in past research.
The release of water that takes place when the super-hydrated kaolinite breaks down could be an important part of the water cycle that causes volcanism along subduction zones.
On Earth, subduction is driven by our planet's hot core, which heats the mantle, causing it to rise up to the surface and move the crustal plates.
A tsunami caused by an earthquake along a subduction zone happens when the leading edge of the overriding tectonic plate breaks free and springs seaward, displacing the sea floor and the water above it.
The links below address (a) the weathering from the uprising Appalachian Mountains and an ice age 450 million years ago, (b) scientists suspecting that our current ice age, which began 40 million years ago, was caused by the rise of the Himalayas and (c) a mechanism for CO2 recycling from subduction zones:
Subduction of carbon - rich crust was surely a large source of CO2 outgassing and a prime cause of global warming, which peaked 50 My ago (Fig. 3b) with the Indo - Asian collision.
