EXTENSION FAILURES: AN EARTHQUAKE MECHANISM

GEOLIGICAL AND GEOPHYSICAL OPINION SEEMS TO BE AGREED THAT ROCK MELTS ORIGINATE IN THE UPPER PART OF THE MANTLE. IF ROCK MELTS ORIGINATE IN THE UPPER MANTLE AND IF, AS VOLCANIC ERUPTIONS AT THE SURFACE INDICATE, THESE MELTS MIGRATE UPWARDS THROUGH THE MANTLE, THEN CONSIDERABLE CHANGES IN STRAIN IN THE ROCKS OF THE MANTLE AND CRUST MUST ACCOMPANY THESE MOVEMENTS. AN EARTHQUAKE MECHANISM IS DESCRIBED WHICH OPERATES WHEN A LIQUID IS PRESENT WITHIN A NON-HOMOGENEOUSLY STRESSED SOLID. EARTHQUAKES ARE DESCRIBED WHICH SHOW DISTRIBUTIONS OF P-WAVE COMPRESSIONS AND DILATATIONS WHICH ARE CONSISTENT WITH THE NEW MECHANISM AND ARE INCONSISTENT WITH SHEAR FRACTURE AS THE MECHANISM AT THE SOURCE. /AUTHOR/
