Fast and reliable characterization of earthquakes can provide vital information to the population, even reducing the effects of strong shaking produced by them. In this study, we explore the minimum time required to estimate the magnitude for subduction earthquakes. Using traditional P wave earthquake ...
The recent high death tolls caused by large earthquakes are a further indication that earthquakes remain one of the most destructive natural hazards in the world and can seriously threaten the achievement of disaster reduction goals. To effectively reduc
We have made a systematic examination of seismograms and bulletins from Mexico City since 1920 to examine whether ma-jor and great subduction zone earthquakes along the Pacific coast of Mexico caused increases of local seismicity in the Valley of Mexico, which is situated in the Trans Mexican ...
quantification and inclusion of the smaller-scale heterogeneity effects into larger-scale constitutive laws for modelling fault processes of societal interest, such as nucleation of natural and induced earthquakes. Methods Experimental procedure The gouge layers are deformed in a direct-shear arrangement (...
Shears — or breaks caused by strain — in rock outcrops like the one pictured here could shed new light on tectonics that occur between major earthquakes in the subduction zone, according to new research. A camera lens shows the scale of the features of the rock. Credit: Provided by Donal...
I try to find an indicator to differentiate the subduction zones where Mw9 earthquakes occur. Stress drops in Mw9 zones are significantly high. I derive the scaling relations, which take into account the variation of . It is derived that Mo should be normalized by 1.5 in the scaling ...
The means of the 10 values at each of two sites on the Pacific plate seaward of the profiles are 57.2 +/- 6.3 and 60.2 +/- 6.6 mW m(-2) Redeterminations of focal depths and fault plane solutions of earthquakes in the vicinity of the heat flow profiles indicate thrust faulting on a ...
We restricted our study to subduction zones, calculating possible gravity field variations associated with elastic stress accumulation in locked areas and with stress release by earthquakes. We used fault-plane solutions for the Alaska-1964, Chile-1960 and Hokkaido-2003 earthquakes, and GPS-based ...
In subduction zones, where one tectonic plate slides beneath another, slow, imperceptible slip, known as 'slow earthquakes' or 'slow slip events', can trigger powerful quakes a little further away. This has just been shown by researchers from CNRS, Université Grenoble Alpes and IRD, in collabo...
