He suspects that about 1 meter of coastal ground uplift resulting
from the fault movement disturbed the sea floor enough to trigger the tsunami.
Not exact matches
The strike - slip and thrust
movements of the
fault may drive water
from the Red Sea in between the
fault and the surface of the igneous block, allowing the two to slip past each other, the scientists suggest.
In those regions, such as California, the
faults that can result
from that rock
movement usually lie close to the surface, making them relatively easy to study.
The ends of the Parkfield
fault were the most likely areas to experience prolonged slipping after the earthquake, Lienkaemper noted, suggesting that slip in these parts of the
fault gradually increased as stress transferred
from movement of the central section of the rupture.
To investigate the mechanisms of the very large
fault movements, we conducted high - velocity (1.3 meters per second) friction experiments on samples retrieved
from the plate - boundary thrust associated with the earthquake.
To find this place where the
fault first began to rupture, the researchers analyze near -
fault strong - motion data (
movements that took place at a distance of up to a few tens of kilometers away
from the
fault) as well as long distance (thousands of kilometers) teleseismic data.
Liverpool Seismologist, Stephen Hicks
from the School of Environmental Sciences, who led the research, said: «It was previously thought that dense geological bodies in an active
fault zone may cause more
movement of the
fault during an earthquake.»
Scientists
from Nanyang Technological University (NTU Singapore) at its Earth Observatory of Singapore (EOS) have discovered a way to forecast earthquakes based on slow
fault movements caused by moving sub layers of Earth.
This is why effortless
movement is good
movement and anything that detracts
from efficient
movement is considered a
fault, whether it results
from injury, breeding, poor structure or bad habits.
Faults include crossing of the feet; throwing the weight
from side to side; stiff steps resulting in a choppy, jerky
movement; and a pacing gait.
