It was maybe 30 seconds. I was reading that this part of the country is very old geologically. The rock is very hard and faulting is minor. When an earthquake hits it was described as like ringing a bell. You guys are in the Ring of Fire.
Hello
Glad you are ok. Having been through some pretty horrific earthquakes, I know EXACTLY what you're feeling right now...
Yep
Like in Finland, then.
Is Finland seismically active? Volcanic?
I spent 2 years in Riverside, California for college education
My wife was in San Francisco right after their big one in the 80s. The aftershocks were very scary, she said.
The very old geologically part. Seismic activity does happen at times, but it's maybe worth 2, max 3. You can notice it, but no drama.
I'm interested in continental drift via my dinosaur interest. I'll have to take a look at Finland.
I'm better thank you! Had a 'wobble' the other day but doing well now
How are you?
Wobble? Did you fall?
The seismic activity here is still due to the last ice age - the ground is still rising up. Kvarken (the narrowest part of the sea between Finland and Sweden) is where it rises fastest. It's indeed significant amounts in a lifetime. They even have a permanent exhibition about it in Vaasa.
A quick scan shows that the parts you mention are some of the oldest rocks on Earth. Very interesting. The glaciers scraped off 25 meters of material during the last ice age.
People don't appreciate how the glaciers deformed the earth with their weight. Technically we are still in an interglacial stage. Pretty mind boggling.
And we have very little natural drama here in many ways. But I have to correct myself - it's the end of the Gulf of Bothnia that rises fastest - 9mm/year. It's just more noticeable in Kvarken as it's shallow.
I grew up 5km from the sea in the Kvarken area, so I grew up with that knowledge. You take someone in eastern parts of the country and they might not know, or remember, but the west coast has known for hundreds of years.
