The frictional resistance on a fault during slip controls earthquake dynamics. Friction dissipates heat during an earthquake; therefore the fault temperature after an earthquake provides insight into the level of friction. The JFAST project (IODP Expedition 343/343T) installed a borehole temperature observatory 16 months after the March 2011 M[subscript w]9.0...
Knowledge of frictional resistance along faults is important for understanding the
mechanics of earthquakes and faulting. The clearest in situ measure of fault friction
potentially comes from temperature measurements in boreholes crossing fault zones within a
few years of rupture. However, large temperature signals from frictional heating on faults
have...
Knowledge of the shear stress on a fault during slip is necessary
for a physically-based understanding of earthquakes. Borehole
temperature measurements inside the fault zone immediately after
an earthquake can record the energy dissipated by this stress. In the
first Wenchuan Earthquake Fault Zone Scientific Drilling Project
hole (Sichuan province,...
A large share of world production of aquatic animals of around 120 million tons per year enters international marketing channels. Since more than 90% of this trade consists of processed products in one form or other and in general represents products from the higher value segments, a comparison on a...
El Salvador's land resources are intensively cultivated.
Labor is relatively abundant and wages are low. This study
analyzed the effects of government policies and observed farm
price distortions on enterprise/weed control system choices
and associated income-employment effects.
A regional linear programming framework was employed to
analyze the effects of alternative...
