Worldwide, there are approximately eighteen annual earthquakes if magnitude 7.0 or higher. Using all the scientific tools available today, however, geologists and seismologists are unable to predict exactly when and where such an earthquake will occur. The best they can do is to identify areas that have a high probability for a severe earthquake. Astrology does more.The Astro-Geology of Earthquakes and Volcanoes is the result of Lind Weber's extensive research into the planetary influences related to earthquakes. After examining thousands of charts, he identified specific signatures for many of the strongest earthquake-prone areas around the globe.In this extensive book Lind Weber presents his findings, which include the significance of:Signs in the four elements: fire, earth, air, waterThe Cancer-Capricorn axisEarly degrees of cardinal signsGrand Trines in the four elementsPlanetary placementsAspect intensitySimultaneous eventsOuter planetsPlanetary complexes and patternsApproaching and separating aspectsAlso presented in the author's findings is the astrological distinction between earthquake and volcano charts as well as how volcanic eruptions can indicate a cyclical timing mechanism. He correlates the vulcanism process with solar activity.
