Discrete scaling in earthquake precursory phenomena :
We analyze the ion concentrations of groundwater issuing from deep wells located near the epicenter of the recent earthquake of magnitude 6:9 near Kobe, Japan, on January 17, 1995. These concentrations are well tted by log-periodic modulations around a leading power law. The exponent (real and imaginary parts) is very close to those already found for the ts of precursory seismic activity for Lo...
متن کاملComparing Liquefaction Phenomena Observed during the 2010 Maule, Chile Earthquake and 2011 Great East Japan Earthquake
On February 27, 2010, the central-south part of Chile was affected by a strong ground motion of Magnitude 8.8, that induced moderate values of peak ground acceleration (PGA) on rock outcrops, in the range of 0.13g to 0.32g, while in soil deposits, a maximum PGA of 0.94g was recorded. The duration of the shaking was close to two minutes as it is substantiated by the available acceleration record...
متن کاملDiscrete Scaling in Earthquake Precursory Phenomena: Evidence in the Kobe Earthquake, Japan
— We analyze the ion concentrations of groundwater issuing from deep wells located near the epicenter of the recent earthquake of magnitude 6.9 near Kobe, Japan, on January 17, 1995. These concentrations are well fitted by log-periodic modulations around a leading power law. The exponent (real and imaginary parts) is very close to those already found for the fits of precursory seismic activity ...
متن کاملFractional dynamics and MDS visualization of earthquake phenomena
This paper analyses earthquake data in the perspective of dynamical systems and fractional calculus (FC). This new standpoint uses Multidimensional Scaling (MDS) as a powerful clustering and visualization tool. FC extends the concepts of integrals and derivatives to non-integer and complex orders. MDS is a technique that produces spatial or geometric representations of complex objects, such tha...
متن کاملNew Evidence of Earthquake Precursory Phenomena in the 17
Significant advances, both in the theoretical understanding of rupture processes in heterogeneous media and in the methodology for characterizing critical behavior, allows us to reanalyze the evidence for criticality and especially log-periodicity in the previously reported chemical anomalies that preceded the Kobe earthquake. − 3 and SO −− 4) concentrations of groundwater issued from deep well...
