Earthquakes are one of the most serious types of natural disaster in the world. Intensive
research and operative efforts have been focused on earthquake prediction, but the …

The structure, status, and processes of the groundwater system, which can only be acquired
through scientific research efforts, are critical aspects of water resource management …

Extensive research on the dynamics of radon gas (Rn-222) originating from the radioactive
decay of radium (Ra-226) in geological subsurface media, sheds light on its periodic release …

This study examined radon concentrations in springs in Kumamoto and Aso regions
following the 2016 Kumamoto earthquake, in addition to monitoring springs near the …

Faults become more and more responsive to stress perturbations as instability mounts. We
utilize this property in order to identify the different phases of the seismic cycle. Our analysis …

The dynamics governing the movement of the radon are complex and dependent on many
factors. In the present study, we characterise the nature of temporal variations of 2-hourly …

At present, Rn subsurface flow can be described only by diffusion and advection
transportation models within porous media that currently exist. Even though the temperature …

The presence of anomalous geochemical changes related to earthquakes has been
controversial despite widespread, long time challenges for earthquake prediction …

Mathematical modeling is used to study the hereditary mechanism of the accumulation of
radioactive radon gas in a chamber with gas-discharge counters at several observation …

Chemical and physical responses of groundwater to seismicity have been documented for
thousands of years. Among the waves produced by earthquakes, Rayleigh waves can …
