English | PDF | 1980 | 203 Pages | ISBN : N/A | 9.3 MB
The tit1e of this booklet refers to a topie in geometrie analysis which has its origins in results of Funk [1916] and Radon [1917] determining, respeetive1y, a synmatrie funetion on the two- sphere 52 fran its great cire1e integrals and a funetion on the plane R 2 fran its 1ine integrals (See Referenees) . Reeent deve1op- ments, in particu1ar applieations to partial differential equations, X-ray techno1ogy, and radioastronany, have widened interest in the subjeet.

This book presents the mechanism of in-situ radon volatilization and outlines the geological requisites to site a radon monitoring well for earthquake warning. A small fractured aquifer under undrained conditions is an effective natural strain meter for earthquake prediction. It shows significant merit on a local basis, and most importantly, the analysis can also be applied globally in subduction zones with similar tectonic settings and physical-chemical relationships.
