Dynamic Stress Drop of Recent Earthquakes: Variations within Subduction Zones
Stress drop is a fundamental parameter of earthquakes, but it is difficult to obtain reliable stress drop estimates for most earthquakes. Static stress drop estimates require knowledge of the seismic moment and fault area. Dynamic stress drop estimates are based entirely upon the observed source time functions. Based on analytical formulas that I derive for the crack and slip-pulse rupture mode...
متن کاملRepeating Earthquakes as Low-Stress-Drop Events at a Border between Locked and Creeping Fault Patches
The source of repeating earthquakes on creeping faults is modeled as a weak asperity at a border between much larger locked and creeping patches on the fault plane. The x−1 2 / decrease in stress concentration with distance x from the boundary is shown to lead directly to the observed scaling T M ∝ 0 1 6 / between the average repeat time and average scalar moment for a repeating sequence. The s...
متن کاملGeothermal Energy and Earthquakes in Western Himalayas
It is well corroborated that the earth is relentlessly bubbling inside since its birth and traversing continuously through a geological change. The source of this dynamism is the heat stored inside i.e. the geothermal energy, which is believed to be the product of mainly the decay of natural radio-isotopes in the crust and mantle, and in the core of earth. This heat exerts pressure towards the ...

Meert J .G. and Smith, D.L. , 1991. Heat flow at the Platanares, Honduras , geothermal site. In: F .Goff (Editor), Honduras A Geothermal Investigation. J. Volcanol. Geotherm. Res., 4 5 : 9 1 9 9 . Three boreholes, PLTG-1, PLTG-2 and PLTG-3, were drilled in the Platanares, Honduras geothermal system to evaluate the geothermal energy potential of the site. The max imum reservoir temperature was p...
متن کاملPreliminary evaluation of induced seismicity at the Karkheh dam site in southwest Iran
The reservoir-induced seismicity (RIS) at the Karkheh dam site with a reservoir capacity of about 7.4x109 meters is investigated. Based on the assessment of the seismicity of the dam site in equal time periods before and after reservoir impoundment, it was found that the number of earthquakes have been tripled after impoundment, while their magnitudes and focal depths become smaller. The averag...
