Sentences with phrase «fluids from the fault»
Located in an area that has ruptured six times since 1857, the hole provided the first opportunity to observe directly the conditions under which earthquakes occur, to collect rocks and fluids from the fault zone for laboratory study, and to continuously monitor the physical condition within an active earthquake nucleation zone.

Now, over the coming weeks, a team of international researchers are returning to offshore Sumatra to collect marine sediments, rocks and fluids from this particular zone for the first time to gain a better understanding of the materials and to collect data for predicting how they behave in fault zones to generate large earthquakes.
The silent earthquakes may then take place when a batch of fluid from the slab is working its way up — as the fluid passes, it will unclamp the fault zone a little bit, perhaps allowing some slow slip.
«When pore pressure increases far enough over the background level, the fault fails and cracks form, releasing fluid from the basin,» Goodwin explains.
The risk of human - made earthquakes due to fracking is greatly reduced if high - pressure fluid injection used to crack underground rocks is 895m away from faults in the Earth's crust, according to new research.
Her research interests include recurrence modeling from earthquake geology data, fault mechanics, in particular the role of fluids in faulting, and sensitivity of probabilistic earthquake risk models to earthquake source modeling and assumptions.
Increased pressure from fluid injection may unclamp the fault and allow slippage, resulting in surface shaking.
After graduate school, Trenton did postdoctoral research at the University of Washington where he studied the mechanical behavior of fault gouge from Death Valley, CA, and then worked as a consulting geologist at Golder Associates, where he created 3D discrete fracture network and fluid flow models for clients in the petroleum industry in the North and South America, and Asia, and nuclear waste isolation industries in Japan, Sweden, and Finland.
