A larger Mag 6.4 earthquake tripped offshore of Seattle WA last night.
It is the latest in a small swarm of Mag 4, Mag 5, and now Mag 6 earthquakes that began two days in the Cascadia Fault Zone that runs from British Columbia south to Northern California.
The Cascadia Fault is regularly hit with Mag 8 (average interval 350 years) and occainsional Mag 9 (interval about 580 years) earthquakes. The last very large killed thousands of native Indians up and down the Washington and Oregon coastline in January 1700, and hundreds more in Japan from its tsunami waves.
Depends if it pops. 🌋😵💫😳
The quakes aer not associated with the cascadia as it is the thrust fault/ convergent plate boundary along the north west coast. These quakes are associated with a spreading ridge system to the west. The only connection is that these two features bound the Fallon plate.
It is quite likely that the New Madrid had some before quakes. It certainly had a lot of small quakes between the very big ones. Small population, limited information, although Audibon was collecting in the area and wrote something about it. One thing probably not heard here is that Caracas, Venezuela had a major quake during that cycle which killed around 20,000. In earlier centuries, Lisbon, Portugal was destroyed by a terrible tsunami, and of course also had quakes. About a month later, Boston had the worst quake ever recorded in that part of the country. I think some events in North Africa were also recorded around that time.
The Carolinas had a bad quake about 20 years after the Civil War, although not on the scale of New Madrid or San Francisco which occurred around 20 years after that.
It appears that some of these major events are regional in nature. When Mt. Pelee blew on the island of Martinique in 1902, the volcano on St. Vincent blew within the same 48 hour period. One captain at sea reported that the ocean suddenly dropped about 4 feet, and sharks were jumping out of the water because it got so hot.
Reports have been made after studying old flood lines going down some of those volcanoes. High danger of many people killed if these volcanoes blow and melt large quantities of snow. Remember that terrible volcanic flood event in south America that killed 23,000 with the mud flow?
gleeaikin-what you are saying is like a tree falling in the forest. Now everyone will know.
David Wilkerson, Christian pastor/speaker, predicted in his book "The Vision" that a catastrophic earthquake would hit the central portion of the US, destroying many cities, taking many thousands of lives. His only mistake was putting a timeframe on it.
When it didn't happen before he passed away in a car accident people ridiculed him. But many are convinced he was referring to a quake along the New Madrid fault line.
I, like you, believe that something is long overdue and when it hits, it will indeed be catastrophic beyond all imagination. Wilkerson's "vision" will come to pass, just not when he predicted it would.
