OK, this is a shorty… just a strange thing I tripped over and have no clue if it means anything or is just a strange coincidence.
I was looking up one thing, and hit another thing, that got me thinking about earthquakes, and…
An amusing page that has an interest in the Winter Solstice and a has dug up all sorts of trivia about it. Being interested in solstices, and right now thinking about winter, I was wandering along and saw:
1866 The Gossips of Rivertown: December 2010
1866 – The Winter Solstice this year coincides with a full moon–something that only happens every three decades or so. Besides that, the Moon tonight reaches perigee–its closest point to the Earth. The last time these three phenomena– the Winter Solstice, a full moon, and perigee–happened at the same time was in 1866.

1878 The Popular science monthly
1878 – In 1878 the pain decreased 200 hours, while an equally remarkable fall was shown in the barometric curve. The law of relationship of low pressure and high temperature to the amount of pain and the number of attacks of pain and the number of storms becomes more apparent in considering the quarterly and monthly distribution of pain and storm. “The winter months hold the advantage as pain- producers,” while in quarterly amounts the first quarter, beginning with the winter solstice …

What I’d been looking at was the winter of 1878. That someone had pain relief wasn’t all that useful… but I noticed the entry just above it, too. Full moon, perigee, winter solstice. Gee, were there any earthquakes of note then? Perigee and full moons ought to be increasing stresses. So any time in the lead up to winter would be a time of increasing tidal stresses. Anything happen?
Mecklenburg, North Carolina Earthquake
August 31, 1866
On the last night of August, in 1886, the people of Mecklenburg were shaken up, and many of them alarmed at the convulsions of nature.
This earthquake was part of the Charleston Earthquake.
The Charleston Earthquake of 1886 was a powerful intraplate earthquake that hit the area of Charleston, South Carolina. After the 1811 and 1812 quakes in New Madrid, Missouri, it is one of the most powerful and damaging quakes to hit the southeastern United States

It also looks like San Francisco got whacked on the ‘lead in’ then rumbled some in the following year up to the target date:
October 1, 1865
Eureka and Ft. Humboldt badly damaged by an earthquake today.
October 8, 1865
Much of San Francisco was wrecked by an earthquake today. The chief damages to buildings were to Popper’s Building, corner Battery and Washington streets. The latter building was completely ruined. The California Engine Company’s house, Market and Sansome sts., was severely injured and rendered unfit for occupancy. The chimney in the rear of the Lick House was shaken down. Stoddard’s Warehouse on Beale St. is said to have been thrown out of place several inches. On Third St. from Market to Howard, the window glass was broken in many places. On Washington St. also, the glass appears to have suffered from Dupont St. down to Montgomery. On the marshy lands in the vicinity of Howard and Seventh streets, lamp posts, water pipes and gas pipes were broken and thrown out of position. The ground on Howard St., from Seventh west to Ninth, cracked open, leaving a fissure nearly an inch wide.
October 9, 1865
There was an earthquake shock today, and the earth continued to vibrate for 24 hours.
November 24, 1865
Earthquake felt in San Francisco and Santa Cruz.
December 7, 1865
Light shock of earthquake today.
February 18, 1866
Earthquake felt today.
March 26, 1866
Earthquake at 12:30 p.m. today. It was felt quite severely at Monterey.
June 5, 1866
Rather heavy shock of earthquake in San Francisco today.
August 19, 1866
Earthquake felt in San Francisco and Oakland.
I know this place. We have ‘frequent’ quakes. But that much shaking big enough to do damage and felt variously from Monterey to SF to Oakland was something of significance. Up to Eureka and Humbolt Bay implies a long section of the San Andreas was active in unison.
The above about Charleston is a bit odd, in that one date is 1866 and another is 1886, yet here’s another that talks about 1866:
1692, Port Royal, Jamaica
1755, Lisbon, Portugal
1811 New Madrid, Missouri
1866 Charleston, S. Carolina
1906 San Francisco
1972 Managua, Nicaragua
1985 Mexico City
1997 Central Italy
So I suspect something happened in 1866, then perhaps again in 1886?
The Himalaya was raised by earthquakes, millions of them, and it continues to rise. Major shocks, reaching Mercalli intensity X (“most masonry and frame structures destroyed with foundations”), struck Kathmandu in 1810, 1833, 1866, and most recently on January 16, 1934.
Then there is this set in Greece that runs from 1866 to 1886 as well, odd that:
1866 – A strong earthquake in the Kythera Strait on 6 February 1866 generated a tsunami. There was significant earthquake damage to Kythira The tsunami reached a runup height of 8 meters at Avlemonas on the eastern side of Kythera island and caused damage to houses (Fuchs 1886, Leonhard 1899).
1867 – A strong earthquake on 20 September 1867 with epicenter near Mani in south Peloponisos generated a strong tsunami. There was heavy damage in Peloponisos and slight damage at Kythira. The tsunami affected coastal areas at Kythira, Crete and Cyclades and reached islands in the Ionian and south Adriatic seas (Papazachos and Papazachou, 1997).
1886 – A large, destructive, earthquake on 2 7 August 1886 in SW Peloponnisos generated a local tsunami(Galanopoulos, 1941 and Papazachos and Papazachou 1997). The quake was slightly felt in Kythera (Galanopoulos, 1953). No details about the tsunami are available.
Then, happening near now:
06.01.2010 Costa Rica – Volcanic Eruption at Turrialba
Today, an eruption occurred at Turrialba volcano in Costa Rica. The eruption emitted ash and gas. The volcano had been showing signs of activity since the weekend. Twenty people were evacuated. This is the first eruption at the volcano since 1866.
Which now gets me thinking about volcanoes:
The eruption of 1866
The volcano remained quiescent for only 55 years after the eruption of 1707. Its dormant stage was soon interrupted in 1866 by a series of seismic events which continued over a period of two week. The waters of the eastern shore of Nea Kameni became noticeably warmer and the sea was colored by fluids seeping from the magma that had begun to rise.
The first lavas appeared on February 4th, in the middle of the cove, and two days later the eruptions began, increasing in number and sending lava fragments to a distance of more than 700 meters. The activity continued until October 15, 1870. The quantities of lava produced during this period tripled the size of Nea Kameni. A small strip of sea continued to separate Mikri from Nea Kameni; this area became known as Kokkina Nera (Red Waters).
The observant sorts will see that 1707 and remember that about 1707 there was a great quake in Japan…
While presently Santorini is making ‘clearing the throat’ rumbles and minor quakes.
So we’ve had this volcanoes go off in the same time frame as a great quake in Japan… now it’s rumbly after a great quake in Japan. I don’t like coincidences… especially when the first time had a great quake near Alaska and had Fuji wake up and erupt… These things are starting to form up in related groups of activity. So watch mount Fuji, Santorini, and Cascadia. If one of them goes in the next dozen years I think we’ve got something…
Ofu-Olosega Volcano – John Seach
14.17 S, 169.61 E
summit elevation 639 m
The islands of Ofu and Olosega are located in in eastern Samoa. They are separated by a narrow strait, and are composed of two eroded, coalescing basaltic shield volcanoes.
A submarine eruption occurred in 1866 at the opposite end of the two islands, 3 km SE of Olosega, along the ridge connecting Olosega with Ta’u Island. On 7th September 1866 residents of the islands of Ta’u and Olosega felt 3-4 earthquakes in an hour. On 9th September 39 earthquakes were felt.
Lately we’ve seen many quakes in the region of the Pacific near Samoa… often located on mountains / volcanic islands.

Current status: minor activity or eruption warning (3 out of 5)
last update: 22 Feb 2012 (degassing and incandescent spots at several locations on the West Crater)
Typical eruption style: Explosive.
Turrialba volcano eruptions: 1723(?), 1847(?), 1853, 1855, 1861(?), 1864-65, 1866, 2010 (Jan 4) – ongoing
I note in passing it had a 17xx eruption too…
I also note in passing that Krakatoa had a major event in 1883, in that same general 1866-86 window.
Now all of this is in the “climb out” of the Dalton Minimum ( 1790 to 1830 ) so to the extent there’s a solar cycle angle, we’re likely looking at another 50 to 60 years. But to the extent it’s a lunar cycle? Haven’t looked at that in depth.
Yes, it’s all just numerology and ‘wiggle matching’ of a very poor form. Just noticing that the same numbers / dates cycle around.
Yes, it needs a much more rigorous examination before you can conclude anything.
Yes, it’s likely nothing other than finding what you look for (1866) followed by too wide an acceptance level (what does 1886 have to do with 1866 other than one page that probably has a typo?) and self confirmation bias.
And probably even more.
But I also have to note that the Maunder Minimum was ending just about 1700… running from about 1645 to 1710. And that has a remarkable closeness to 1707… Just saying…
What does it all mean?
Probably nothing. On the other hand, a search for interesting volcanic or earthquake events at the entry into prior grand minimum events would be interesting. If there is some kind of ‘stirring’ that happens at the entry and exit (length of day change is known to happen…) then I could easily see similar events caused by the ‘sloshing’ each time.
That so many interesting dates are so close to each other is also interesting. The same volcano or quake location having the same year, or within a couple of years? When things are supposedly semi random and happening every few hundred years, that close is just surprising.
At any rate, as I’ve said, I’m trying to get a lot of things off my “to do” board and onto at least a ‘sort of done and something posted’ list, so I must end this one here. Leaving a rather large “dig here” of entry / exit from minima vs quakes and volcanoes and ‘date of stop / start’ matches for quakes from those times and volcanoes from those times.
But I’ll not be spending a lot of time sleeping near the shore in the Cascadia region for the next 20 years… or hiking up mount Fuji.
It’s also an odd ‘coincidence’ that folks talk about ‘earthquake weather’ and that is weather that is particularly warm, humid or cloudy / cloying, and still. ( At least, that’s what it means to me). The wiki on it mostly calls it bunk, then says:
Some recent research has found a correlation between a sudden relative spike in atmospheric temperate 2-5 days before an earthquake. It is speculated that this rise is caused by the movement of ions within the earth’s crust, related to the oncoming earthquake. However, in this case the atmospheric changes are caused by the earthquake, rather than causing it.
I don’t care which direction causality runs as long as the correlation is strong… So is there something about the lead in and lead out of a solar grand minimum that causes that kind of event? I guess we’ll just have to wait and see.
