We compare teleseismic P-wave records for earthquakes in the magnitude range from 6.0 to 9.5 with synthetics for a self-similar, ~2 source model and conclude that the energy radiated by very large earthquakes (M,, > 8~) is not self-similar to that radiated from smaller earthquakes (Mw < 81). Furthermore, in the period band from 2 sec to several tens of seconds, we conclude that large subduction...

The use of thermal anomaly to monitor or predict earthquakes has shown little success. Various methods have been propounded to monitor earthquakes with little emphasis on fundamental soil quantities. This paper propounded a vital factorsoil density ratio which can be used to monitor earthquakes. The magnitude of earthquakes was discovered to increase when the soil bulk density decreases very lo...

The paper examines the application of semi-Markov models to the phenomenon of earthquakes in Tehran province. Generally, earthquakes are not independent of each other, and time and place of earthquakes are related to previous earthquakes; moreover, the time between earthquakes affects the pattern of their occurrence; thus, this occurrence can be likened to semi-Markov models. ...

Using a catalog of seismicity for Southern California, we measure how the number of triggered earthquakes increases with the earthquake magnitude. The trade-off between this relation and the distribution of earthquake magnitudes controls the relative role of small compared to large earthquakes. We show that seismicity triggering is driven by the smallest earthquakes, which trigger fewer events ...

interferometric synthetic aperture radar (insar) technique is valuable tool in monitoring crustal deformation due to its large spatial coverage and high spatial resolutions. in this paper, the intersiesmic crustal deformation occurred before earthquake on august 2012 in ahar-varzegan located in north-west of iran is studied using persistent scattering interferometry. the psi algorithm used in t...

This paper inspects possible influence of solar cycles on earthquakes through of statistical analyses. We also discussed the mechanism that would drive the occurrence of increasing of earthquakes during solar maxima. The study was based on worldwide earthquakes events during approximately four hundred years (16002010).The increase of earthquakes events followed the Maxima of Solar cycle, and al...

Human activity recognition (HAR) is one of the key applications health monitoring that requires continuous use wearable devices to track daily activities. This article proposes an adaptive convolutional neural network for energy-efficient HAR (AHAR) suitable low-power edge devices. Unlike traditional (early-exit) architecture makes early-exit decision based on classification confidence, AHAR a ...

[1] Over 109 small earthquakes (Mw 0.4–3.9) were detected during January 2011 to February 2012 in the Youngstown, Ohio area, where there were no known earthquakes in the past. These shocks were close to a deep fluid injection well. The 14 month seismicity included six felt earthquakes and culminated with aMw 3.9 shock on 31 December 2011. Among the 109 shocks, 12 events greater than Mw 1.8 were...
