In order to study the precise geographical distribution of helium isotope ratios in northeastern Japan and compare it with geophysical data, we collected 43 gas and water samples from hot and mineral springs in the region where the ratio had never be

The northwestern region of the Iberian Peninsula was traditionally considered a seismically stable area. However, the 1995 and 1997 Galicia earthquakes of magnitude 4.6 and 5.3 produced significant damage in the region (intensity EMS: V), and these e

Atmospheric 222 Rn concentrations were determined over a 10a period, which included the date of the Kobe, Japan earthquake, on January 17th 1995. It was found that the seismically related 222 Rn anomaly was higher than the 99% confidence limits for t

Following the first phreatic explosion on 17 November 1990, hot spring gases were collected periodically over the next 10 years for 3 He/ 4 He isotopic ratio and chemical analyses from three hot springs (Obanma, Unzen and Shimabara) located around Un

I found a curious oscillating behavior in secular variations of relative ground level in the Tokai district, central Japan. The period of the oscillation is becoming shorter acceleratedly with time, which thereby predicts the existence of a “critic

A new method for continuous monitoring of fumarolic gas flux at a bore hole is here described. We measured the vertical temperature distribution continuously using a DTS (Distributed Temperature Sensor) system in a volcanic island, Izu-Oshima, centra

We made an extensive compilation of noble gas data obtained from MORB, oceanic island basalts (OIB) and diamonds. On the basis of this data base, we discuss the primordial noble gases in the Earth and its implications on mantle evolution. We conclude

Three boreholes (500, 800, and 1800 m) were drilled near the Nojima Fault, which is one of the Hyogoken-Nanbu Earthquake faults. Water injection experiments were conducted from the 1800-m borehole over three periods (1997/2/9–11, 2/12–13, 3/16–

Water-level/pressure data recorded at a dense network of 16 wells of depths ranging from 23 to 201 m within 400 m of the Tono Mine in Gifu prefecture, central Japan, have been studied in search of possible earthquake-related changes. The study area i
