Earthquake weather is a type of weather popularly believed to precede earthquakes. Geologists maintain that there is no connection between weather and earthquakes.

has to do with the phases of the moon. Earthquakes are not predictable but some think they are more likely to occur at certain times. The moon is powerful enough to control the tides on earth, raising the whole sea up 3 or 4 or more feet at high tide which occurs twice a day, once when the moon is directly ovewrhead and a second lesser high tide when the moon is on the opposite side of the earth from the other high tide position. At certain times in it's orbit the moon is closer to the Earth this is marked in an Almanac as "the moon runs low". there is water underground and inside rocks that is also subject to this gravitational pull. The theory is that earthquakes are more likely to occur at high tide, when the moon runs low, or on a full moon, I think a new moon and the day the moon changes quarters are supposed to be more likely too.

Have to update this after checking my reference. The moon has a circular orbit but at certain times will be closer to the spot you live in In northern hemisphere the moon rides high at this time and in southern hemisphere the moon is said to run low similar to the way the sun is higher in the sky in summer than in winter. When the moon's orbit crosses the equator an earthquake is supposed to be more likely in either hemisphere.
