Hydrological Signatures of Earthquake Strain
The character of the hydrological changes that follow major earthquakes has been investigated and found to be dependent on the style of faulting. The most significant response is found to accompany major normal fault earthquakes. Increases in spring and river discharges peak a few days after the earthquake, and typically, excess flow is sustained for a period of 6-12 months. In contrast, hydrol...
متن کاملGEAR1: A Global Earthquake Activity Rate Model Constructed from Geodetic Strain Rates and Smoothed Seismicity
Global earthquake activity rate model 1 (GEAR1) estimates the rate of shallow earthquakes with magnitudes 6–9 everywhere on Earth. It was designed to be reproducible and testable. Our preferred hybrid forecast is a log–linear blend of two parent forecasts based on the Global Centroid Moment Tensor (CMT) catalog (smoothing 4602 m ≥5:767 shallow earthquakes, 1977–2004) and the Global Strain Rate ...
متن کاملVariability in earthquake stress drop and apparent stress
[1] We apply empirical Green’s function coda‐based analysis to four earthquake sequences in Japan that span a magnitude range of 1.8 to 6.9, to measure radiated energy, corner frequency and stress drop. We find no systematic dependence of apparent stress or stress drop on seismic moment for these sequences, and find they both are log‐normally distributed; however, we identify several anomalous ...
متن کاملEarthquake Repeat Time and Average Stress Drop
Existing data on source parameters of large crustal earthquakes (subduction events are not considered here) over a wide range of repeat imes indicate that, for a given magnitude (Ms or Mw), earthquakes with long repeat times have shorter fault lengths than those with short repeat imes. A shorter fault length for a given magnitude indicates a larger average stress drop which reflects the average...
متن کاملStress-Strain Field and Theoretical Analysis of RC Bridge
In this paper, a reinforced concrete(RC) bridge built in an interchange, in the city of Kerman (a city located in south of Iran) is examined by the Structural Health Monitoring (SHM) system. During the construction of this bridge such as; the main beams, slab, and retaining walls, some Electrical Strain Gauges were mounted on the main reinforcements at different locations within the body of thi...
