Borealis Meditation

Science and Spirituality

Category: blog (page 2 of 3)

today is the day I put this podcasting to the test!

Today I am teaching a 600 level class. That was one of the motivations behind all this podcasting, to make me more comfortable teaching and giving presentations. I feel being able to play myself back and hear what I sound like, and learn to slow down is helping!

But we put it all to the test today! Wish me luck and send me good thoughts! πŸ™‚

EDIT: I was complimented on my session! I brought rocks in, it was awesome! πŸ™‚

Two people killed and several injured at Kraljevo

From the EQ stats page

Magnitude vs. Ground Motion and Energy

Magnitude Change
Ground Motion Change
(Displacement)
Energy Change
1.0
10.0 times
about 32 times
0.5
3.2 times
about 5.5 times
0.3
2.0 times
about 3 times
0.1
1.3 times
about 1.4 times
This table shows that a magnitude 7.2 earthquake produces 10 times more ground motion than a magnitude 6.2 earthquake, but it releases about 32 times more energy. The energy release best indicates the destructive power of an earthquake. See: How much bigger is a magnitude 8.7 earthquake than a magnitude 5.8 earthquake?

HW: How much bigger? Calculator
Lets do three well known recent earthquakes
1. Haiti M7.0

2. The recent Indonesia one that produces a tsunami M7.8

3. Chile M8.8

Enjoy!

getting ready for another episode

This might be the last one for a while. December and January are my busy months so I am pretty sure combined with that and being out of town I won’t really have time to record. If I can get my hand held recorders working…. (getting the files off them….) then I may have something! πŸ™‚

So here is what you can do to help! I want a feedback/questions section! So send them to me!
please?
email me?

I have several treats for you in this next episode, and since the poll is going along and it looks like the current events were a success then I will run along and round some up!

Pyrite is the mineral this time so send me Pyrite uses and things as well!

thank you all!

HEY YOU!

YES YOU! There is a poll right ——————–>
The last episode I did the lesson about volcanoes and tsunamis was motivated by explaining current events. Did you like that approach?
please let me know!
You can also just comment on this post to let me know.

The question is: Do you like current events as the center of the lesson or more as an example to highlight the lesson and emphasize a point, do you like you lesson floating in the vast expanses of time and space with no current events examples only old well known ones?

Merapi / the state of me / a little AK

Merapi
Its still erupting!

Death toll is now 140+ and the eruption intensified since I recoded the podcast.

I urge you to keep up with this story even though it might be hard…
thank you media for finding something new and shiny
Eruptions blog is a good place to keep up to date!

The state of me
I had high hopes for getting caught up on blogging this weekend and doing some writing other then my thesis but… I have been a little under the weather for the past few days and have been hibernating… which might also have to do with the fact that I woke up to how short the days are getting this week, it sneaks up on you!

A Little AK
its cold but no that cold
The days are short but there is sunlight
and we don’t have a senator
In case you ever thought there could be no write in winner in a senate campaign…
Let me remind you that this is AK
there are less of us
and we are crazy
normal rules do not apply here
at all.
so Murkowski and Miller have lawyer-ed up
and now we wait.
the good news is we passed the ballot initiative thing to fund more school projects! I like those! πŸ™‚

Oh hello blog, I have been ignoring you! its earth science week! :)

Ok, wow I need to get my ass in gear.

Thoughts for a podcast:
– Volcanoes, myths and lore (+ a little science)
– Aurora, basic explanation and a little bit of well known lore up here
– color?
– metallic and magnetic minerals in magic and life
but really this is a blog as well as being about my podcast.
I have 10-15 minutes before my ride comes to get me and we drive home in the now very slick snow. I have a story to share about a volcano in Alaska. I’ll link to some articles but this is my reflections of a talk I went to.
(Quickbird true-color satellite image of Kasatochi Island collected on April 9, 2004. Image copyright Digital Globe.)
Kasatochi
Little Kasatochi. Its a very small island way out in the Aluetian islands. Home in the past to many birds. An important nesting site and a haul out place for sea lions. A biologists dream! its never been inhabited that I know of except by fox trappers. The foxes are gone and the small shack was refinished and every summer biologists would hang out and count birds and enjoy the small island. In terms of the geology it was known that it was a volcano, but hadn’t been active except for some possible activity in the 1800s. Pretty dormant. A small green island with a central lake in the crater, a little blip in the ocean, but the top of a large submarine volcano.
The summer of 2008 was no different then the ones before. Two biologists were dropped off by the research boat that went into the Aleutians every summer to stay on the island and count birds. In early August these biologists began to feel earthquakes on the island. By August 4th they contacted the volcano observatory. Now imagine. You are on a volcano you know its a volcano out in the middle and I mean middle of no where. There is NO instrumentation on the volcano and you feel earthquakes. At first it was no big deal, there are earthquakes in the Aleutians all the time, its not monitored it could be a normal amount of events. There is no background to compare it to. At this point the earthquakes were of a magnitude and possible location that it was considered normal and non-volcanic.
By the 6th however it was very clear that this was very not normal activity. By that night there was a warning listed for the volcano and it was decided those scientists needed to get off the island. The next morning there was a M 5.8 and the closest seismic station on a neighboring volcano began to record volcanic tremor usually seen as being caused by the migration of fluids, water or magma. They needed to get those men off the island now.
The boat that had dropped them off was too far out, the coast guard chopper that was closest to them was in need of a part, and the weather was very over cast. They waited on the shore. They used the sat. phone to call home, the volcano rumbling below their feet. Finally a fishing boat was able to make the seas to get them. The weather was horrible but they got out to the boat and back to safety. Within an hour of their departure….
there was confirmation of a plume. Kasatochi had erupted less then an hour after they left. Two weeks later they returned. The island was grey. Nothing remained. The cabin was under 20-30m of material the beaches were built out. They would not have survived the eruption that much is clear. Rocks the size of cars were sitting on beach where once there had been water.
The official report is that the biologist were off the island less then 30 minutes before the eruption.
That was on close call. The island is getting back to normal again. The birds are nesting, there is some green taking root. Again Kasatochi is an important island for biologists.
Kasatochi is the most energetic volcanic eruption since the inception of the Alaska Volcano Observatory. It was an unmonitored volcano.
*dramatic music*
Welcome to the world I love, the drama, the joy, the excitement of volcanoes.
I hope you enjoyed that! πŸ™‚

I have a little bit of time…

I have some big questions I want answered, but its not something I can answer. So I am going to start making a list and asking people! πŸ™‚ I know I said it was going to be a while before the next show… so I wanted to make it a good one!

Metallic Rocks and Magnetic Rocks
Volcanoes lore and deities

Interview some PODKIN!? πŸ˜€
I think so! Its going to be written answers but I thought I would ask some of my favorite podkin if they have some time to send me some of their ideas. I’m not sure these questions can be answered but! I like hearing other peoples ideas.

Powers in rocks/minerals/geology thats the topic.

πŸ™‚

Oh I wish I wish

there were more hours in the week!

I wanted to get a mini-episode recorded this weekend and look what time it is! 8pm on a Sunday and this is the first I thought of it!

I have a friend coming to town and will be here all next weekend, so no show then either. I did warn you there would be a break somewhere in here! Well here it is! Consider me on hiatus for a bit. if in 2 weeks my thesis-ing is intense I’ll have to put it off again. C’est la vie!

I will try and get something fun up on the blog, I have the “book-o-learning” also known as the lab book for the 101 class here. I will see if there is something fun I can pull out!

Also a listener bought something from me on my etsy show! I am so exited!

I am working on:
– drying catnip for cat toys
– a “The Fool” tarot box (yes they fit cards I checked!)
– hmmmm I’ll think of something πŸ˜‰

Dinner is cooking, and I need to get some reading done!

Take care my students! I am loving all the love and I can’t wait to share more wonderful geology with you all!

Why I Blog: Erik Klemetti (Eruptions) article on AGU website

(an article about a geology blogger I found interesting)

Why I Blog: Erik Klemetti (Eruptions)

I started blogging out of frustration with the lack of knowledgeable commentary on volcanic eruptions on the Internet in early 2008. It all came to a head when a mystery volcano in southern Chile erupted (this turned out to be the eruption of ChaitΓ©n). I searched in vain for some place that was collecting the unfolding information on the eruption and putting it in a geologic context (in other words, the opposite of most mainstream media coverage of geologic events). So, I decided to start my own blog to do just that: take all the random news reports, volcano observatory news releases, satellite images/remote sensing data, and downright rumors and offer commentary on it all through the lens of someone who studies volcanoes for a living…. (READ THE ARTICLE)

The Eruptions Blog

Hey class!

Ok I feel enough like a teacher I am going to just cave and call my listeners my students!
Ok Class! Participation points!
I am going to list some topics and some questions comment or email me to participate in the show! πŸ™‚

Volcanoes:
– are they male or female or does it depend on the volcano?
– got any myths? legends? gods? goddesses?

Geologic time scale
– what in your opinion is a “long time” for you? in history? for the world? What time scale do you feel the divine works on?

Geology and you
– what do you like? what do you want to learn more about?

Ok GO! πŸ™‚
