The Hiroshi Wakita Volume I is a collection of original papers regarding the role of terrestrial fluids in earthquake and volcanic processes. This Pure and Applied Geophysics volume provides the results of some of the most recent studies on terrestrial fluids involved in both processes. It honors Hiroshi Wakita for his scientific contributions. Volume II will be published later in 2006. Both volumes are of value to researchers and graduate students in the field.

Terrestrial fluids, earthquakes and volcanoes: The Hiroshi Wakita Volume II is a special publication to honor Professor Hiroshi Wakita for his scientific contribution to science and commemorate his 10^th anniversary as Emeritus Professor at The University of Tokyo. This second special issue of Pure and Applied Geophysics consists of 10 original contributions written by researchers from Japan, Germany, Italy, Costa Rica, Sweden, El Salvador, Turkey, USA, Greece, and Spain. The discussed subjects include research on earthquake-related hydrologic and geochemical observed temporal...

This, the Hiroshi Wakita Volume III is a special publication brought out by Springer to honor Professor Wakita for his contributions to science. These have been closely linked with one of the major objectives of this 2008 International Year for the Earth Planet. Reducing natural risks in active tectonic and volcanic environments by searching for and detecting early warning signatures related to earthquakes and volcanic eruptions has been a major research goal for Hiroshi Wakita.
