Solution...turn off the sun. Kill two birds with one stone...earthquakes AND global warming.
The San Francisco earthquake of 1989 happened at 5:04 Pacific time, well before sunset.
The Northridge quake in LA in 1994 happened in the middle of the night, well before sunrise.
The Whittier Narrows quake of 1987 happened about 8:30 am, if I recall correctly.
Does he really mean within a few hours of dawn or dusk, as opposed to high noon? Or is this is theory not supported by evidence?
Every quake does happen at dawn or dusk,.....somewhere around the globe....
FWIW, his theory has been investigated before and the forces are off by orders of magnitude. What he might be sensitive about, is that most earthquakes, which happen to occur in the very early morning hours, are also coincident very low commuting motion. Most folks are asleep or stationary.
When the quakes happen at dusk, be it morning or evening, highways tend to be congested and public assemblies rapidly forming. Larger casualty rates are found in the larger older structures which might fail in those events.
