Lights in the sky before EQs.
I have been researching prospective novels on two major earth phenomena—the great New Madrid quakes of 1811-12, and the Mt Pelee eruption and Caribbean Plate disturbances of 1902 that killed around 40,000 people. Little noted in recent almanacs is that the New Madrid disturbances also were reflected in a major quake in Venezuela that killed around 20,000 people.
The upshot of all this research is a tentative conclusion that periodically, perhaps at 90 to 100 year intervals the earth experiences several decades of disturbances and then settles down for a few decades after which there is another smaller episode of disturbances, followed by a shorter quiet phase, and then the next 90-100 year sequence. This is for the past several hundred years. I have not yet carried this research back further, but probably will at some point.
Here are the major points I am proposing.
1) 1800s. Starting in 1783, the Laki Fissure event in Iceland and culminating in the 1811-12 events best known by the US New Madrid events, and the great Tambora volcano in 1815.
2) 1900s. Starting with the great Krakatoa eruption in 1883, including the Charleston EQ in 1886, the terrible Caribbean Plate events of 1902, the San Francisco EQ of 1906, and culminating in the great Katmai/Novarupta explosion in Alaska in 1912.
3) 2000s. Starting with Mt. St. Helens in 1980, Pinatubo in 1991, several VEI 5 volcanoes in North and South America in that period, the major EQs in Mexico, Turkey, Pakistan and the terrible EQ tsunami Christmas 2005, and now a big one in Chile.
Unfortunately, I do not think this cycle is finished, so perhaps we will have a very major volcano before long of the magnitude of Tambora or Katmai. I wonder if major earthquakes start magma moving toward the surface? If so, then Indonesia or South America would be good candidates. If I lived in California or Alaska, I would have a good family emergency EQ plan in place.
Apocalypse soon?

My husband was just remarking how San Francisco and Los Angeles have been unusually quiet for the last decade....
