Friction along the fault locks the plates together until enough strain builds up to cause the plates to slip, unleashing an earthquake.
But increasing fluid pressure at depth reduces
the friction along the fault, sometimes triggering an earthquake.
For now,
friction along the fault is acting like an emergency brake.
Not exact matches
On the other hand, if the two plates were stuck together by
friction, strain would build up in the rocks and the upper plate would bend down
along the outer edge and thicken inland, humping upward until the rocks
along the
fault failed.
«How
friction evolves during an earthquake: By simulating quakes in a lab, engineers study the way that
friction changes
along a
fault during a seismic event.»
They then put the two pieces together under pressure, simulating the static
friction that builds up
along a
fault line.
