Earthquakes are often found to be associated with eclipses. An eclipse is always liable to cause seismic disturbances if it makes aspects to the angles and more so if it places malefics on the angles. The September 1 solar eclipse chart makes a hard aspect to Uranus on the MC at Pawnee. The New Moon, also creates a potent T-square with Saturn and Neptune with Saturn still conjunct the red supergiant star Antares which Diana Rosenberg links to earthquakes . Notice that at the exact time of the earthquake, the eclipse T-square straddles the horizon axis confirming its role.
