Pieces of a puzzle

Ever since my oldest son got interested in volcanoes, I got an education about tectonics plates and how they work. So this article sort of took the discussion of tectonic plates from how they work to when did they first come about?

The article is entitled “The Earth’s Shell Has Cracked, and We’re Drifting on the Pieces” by Natalie Angier at the New York Times. Definitely taking the talk to the next level on tectonic plates.

Gifts from the volcano goddess Pele

So while the Kilauea volcano has done tremendous damage as it has erupted, it has also done some (at least to me) amazing things. The most obvious being creating nearly a mile of additional  coastline to the island.

As this article however, also points out, it’s created what is know as Olivine or the gem Peridot. The article is entitled “Hawaiian Volcano Offers Gifts of Gemstones Delivered from the Sky” by Melissa Breyer over at Treehugger. They’re even green to boot.

Volcanoes 101

So as I said in an earlier post entitled Volcanoes, I learned a lot from my son and his interest in volcanoes and science projects over the years, but apparently there was still a lot for both my son and I to learn. These two articles tonight cover topics in which we didn’t discuss much, if at all.

The first is entitled “When it Comes to Volcanoes, What is Laze?” by Noel Kirkpatrick over at Mother Nature Network which talks about these steam plumes which are created when the lava flowing out of Kilhauea, hits the ocean. Now while we did talk about the reaction of lava when it hit the ocean, I must admit I didn’t know there was an actual term for that.

The second article is entitled “Why Eerie Blue Flames Just Erupted from Hawaiian Volcano” by Laura Geggel over at Live Science and talks about the blue flames that are currently popping up. These I don’t remember ever talking about. Oh well, back to school we go.

One of my oldest son’s favorite topics all through school when he was growing up was volcanoes. Even today, we still have some of the evidence of that, mostly from science fair projects that he did over the years. Consequently since it was one of his favorite things, I came along for the ride and I must say, I learned a lot.

One thing I learned is that there are lots of them and many continue to erupt or disrupt our planet even to this day. One needs to look no further than Hawaii’s Kilauea volcano. Meanwhile on the other side of the world in New Zealand, the crater of a dormant volcano has apparently collapsed.

You can learn more about it over at Live Science in the article entitled “Enormous New Zealand Sinkhole to be Fenced in so Cows Aren’t Swallowed Up” by Yasemin Saplakoglu. So even today, I sometimes wonder what might happen at various volcanoes all around world.

Two maps in one (post)

I don’t often post about two articles but tonight I’ve decided too, in large part because they both include maps. The first article, entitled “First ever digital geologic map of Alaska by the United States Geological Survey and over at Science Daily, has an awesome map and as I think I’ve said before, I do love maps.

The other article, while not about a map, does have a pretty cool map that goes along with it. It’s entitled “Intriguing Seismic Activity along the Cascadia Subduction Zone” by Dana Hunter and also over at Science Daily. Like her, I’m sort of a geology junkie too.

Wooden trees, what wooden trees?

Now last night I was talking about underground forests but tonight I’m going to talk about another kind of forest. This is a forest of lava trees.

What are lava trees you might ask? Well, check out this article over at the Mother Nature Network entitled “What are lava trees and how are they formed?” by Catie Leary for the answer.

Science fairs and volcanoes

I have to say that I learned about lava tubes from my now fifteen year old son. When he was growing up, he loved volcanoes and consequently I learned to love them too. In fact, it was during this time that he participate in our local science fairs and of course, he chose volcanoes like Mt. St. Helen and  Mt. Vesuvius.

Anyway, when I saw this story over at GrindTV, I knew I had to post it. It  also reminded me of a book I read a couple of years ago entitled Subterranean Twin Cities about the caves of the twin cities.

The article I’m talking about is entitled “Stunning Photos Taken of Secret Lava Cave” by David Strege at GrindTV. It’s about the lava caves located in the state of Washington. The photo’s are breathtaking.
