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...

— 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 ...

Although earthquake disasters are often termed as a 'natural' disaster, a critical analysis reveals that most of them are in fact man-made, and caused by the human activities that are related to poor construction practices in both developed and developing countries. Damage scenarios of recent earthquakes show ample examples in support of this statement. While risk perception is an important iss...
