Disaster In My Region: AW Check In Thread (Tornadoes, Floods)

A series of earthquakes caused the eruption.

Minor nitpick here. The earthquakes in this case didn't cause* the eruption, they occurred as the magma pushed up through the rock.


**Rarely a large quake might impact an eruption, cause magma chambers to shift. And technically the moving tectonic plates which cause earthquakes are also responsible for most volcanoes. So the whole system is intertwined.

Prayers for the safety of all people...and animals...in Hawaii.

I went by what someone in the video reported.

Wasn't personal. I'm frequently out to educate the world. Can't help myself.

BBC is showing a couple home videos that are really cool. USGS person: they've known for weeks it was building to an eruption. Sounds like everyone and their pets are safe but it's not known if any homes will burn down like before.

I was there in 1983 when this round of eruptions began. It's been going on that long.

I lived in Hawaii between 1974-78, and I remember strongly how destructive Kilauea could be when it was riled. I hope everyone is staying safe.

It can be horrible. Just the ash is bad, but falling lava is not fun. I'm hoping everyone is safe.

Pyroclastic flow / nuée ardente (likely what killed the people of Pompeii) is especially nasty. None of it is good though.

Wrong kind of volcano.

Not downplaying the danger here mind you. Slowly oozing lava can look benign but still contain very explosive gasses. And not much stops the lava pouring though housing developments.

"90% of the volcano is lava rather than pyroclastic material."

If you want to see a good pyroclastic flow, Mt St Helen's eruption was one of the best documented in history. Perhaps a new thread if you are really interested?

Just been reading the FB page of a friend in Hawaii and at least one of the magma-caused earthquakes was big enough to shake up the north side of the Big Island.

Shit.

Hope everyone is OK!

I live in North Texas, in a tiny town. We had a quake last night that hit about 8 miles north from 5km deep. 3.5 on the scale, lasted for maybe six seconds. No damage here, but my cousins were closer and in prefab housing, so they felt it more acutely.

This is the second "significant" quake we've had in the last 5 years (meaning a quake we could feel) and both times it felt like a car slammed into the garage, but this time, the floor rolled, too. I DO NOT understand how people can continue to live in areas where the numbers are closer to 7 on the scale. Yikes.

Sat Nam! (Literally "Truth Name"--a Sikh greeting)

Yeah, earthquakes are scary. I've lived in earthquake territory most of my life. And only experienced two, maybe three, earthquakes of 5 or more on the Richter scale.

And that's why we can live in these areas. The earthquakes we can feel aren't that frequent, and most of those aren't deadly.

Now, fire,...that's another story.

Most of us in earthquake territory feel the same way about those of you in tornado and/or hurricane territory, btw.

Done of the above is to minimize your scare.

You learn never to place breakables above your bed or bathtub.

Not to dismiss the loss of people's homes but this is an incredible video:

Notice the lava fountains at the head of this massive lava flow.

Two more: lava fountains from last night.

Methinks someone is a volcano geek

I am too of course - took a class in college called “Earthquakes and Volcanoes”. Probably one of my most memorable classes ever, due to the subject matter and the professor. We affectionately called it “Shake n Bake”

Back on topic, hope everyone is staying safe and out of harms way.

Sorry, hope I didn't get too far off-topic. That didn't happen to be “Earthquakes and Volcanoes" at the UW with Tony Irving did it?

Volcanoes are scary!

Hoping our California members are safe. The fires out there are disturbing.

Sat Nam! (Literally "Truth Name"--a Sikh greeting)

Yes. Holding the good thought for the safety of all AW members (and everyone else) in CA fire country. Please let us know how you're doing, if you're able.

My cousins live in Redding but they are close to the center on the city map and away from the fire areas. But what a nightmare more than 1,000 houses destroyed and those poor people caught in the fire.

My niece's boyfriend's family lost their home in Redding. I used to spend summers near there with my cousins and the Sacramento River is not a small river there. It's terrifying to think a fire could jump it so fast. I have family east of there, likely not to be in the way of this fire but give it time, I'm sure there will be another fire in their area. *Sigh* I got the official notification to evacuate from my home near the Ferguson Fire last night. From what I'm hearing from coworkers it picked up it's activity and spotted over containment in a few places. I voluntarily left last week because the smoke was so bad. This is now the second time I'm evacuated from a fire.

Sat Nam! (Literally "Truth Name"--a Sikh greeting)

Glad you'd already evacuated, Kit. May you have a home to go home to.

May your cousins stay safe, MaeZe.

Blessings,
