No natural phenomena on Earth has the power to shape land and climate as does volcanoes. Since the beginnings of written history, volcanoes have been feared, revered, and worshipped.

The word volcano is derived from the name of Vulcano, a volcanic island in the Aeolian Islands of Italy whose name in turn originates from Vulcan, the name of a god of fire in Roman mythology. Vulcan was the son of Jupiter and Juno.

Most volcanoes are created by plate tectonics, either by two plates pulling apart, such as those in Iceland, or by one plate going under the other, such as the volcanoes in the Pacific Oceans' Ring of Fire. A third type of volcano is formed when hot magma deep within the Earth rises to the surface and melts the crust as the tectonic plate moves over it. The Hawai'ian Islands, and the Yellowstone Caldera, are examples of this.

Volcanoes are classified as active, dormant, or extinct. An active volcano is one that has either erupted in the past 10,000 years, or has the potential to erupt. A dormant volcano is one that hasn't erupted for many millenia, but still has a potential to erupt, perhaps in the distant future. The Yellowstone Caldera is an example of this. An extinct volcano, such as Devils' Tower in Wyoming, has no chance of ever erupting.
Devils' Tower:


There are several types of volcanoes. The Hawai'ian Islands, for example, are shield volcanoes. Their lava has a low silica content, which causes the lava to be runny and flow rapidly, making the volcano broad and gradually sloped. Cinder cones are usually small volcanoes that consist of ash and cinders; these volcanoes have a relatively short life span.

The type of volcano that most people think of when they think of volcanoes are stratovolcanoes. They have alternating layers of lava and ash, and are conical in shape.



1. Magma chamber
2. Bedrock
3. Conduit (pipe)
4. Base
5. Sill
6. Branch pipe
7. Layers of ash emitted by the volcano
8. Flank
9. Layers of lava emitted by the volcano
10. Throat
11. Parasitic cone
12. Lava flow
13. Vent
14. Crater
15. Ash cloud

Mt. Fuji, Mt. Kilamanjaro, and Mt. Vesuvius, are examples of stratovolcanos. Stratovolcanoes are also generally the least stable, as they are the type most likely to have an explosive eruption.

The island of Milos used to be a stratovolcano; now what used to be its crater, is now the main bay of the island!



Milos is still volcanically active; in one of the caves on the south coast, the heat from the volcano is still great, and on the eastern shore of the harbour, there are hot sulphurous springs!

Volcanic eruptions can have an effect on climate, both regional and worldwide. Eruptions can create huge deposits of ash over a large area, choking out life. A large enough eruption can block enough of the sun's rays to cool the Earth, as in the 1815 eruption of Mount Tambora, which created global climate anomalies that became known as the "Year Without a Summer", because of the effect on North American and European weather. Agricultural crops failed and livestock died in much of the Northern Hemisphere, resulting in one of the worst famines of the 19th century. "The Great Dying", where 90% of living species died out 250 million years ago, is believed to have been caused by about a million years' worth of volcanic activity.

Lawnman came at noon today so now both lawns are nice and tidy. Great to see everything so green. Cool temps with us a couple more days so enjoying as much as I can. With the swing up on my porch, I can go and sit there in the cool morning and just enjoy....

Great catch Sandi. Looks like a party at the old watering hole...LOL

Well off for the night. Going to check out the TV and see if there is anything worth watching. Have a great evening everyone.

Good evening! Not much to chitchat about; gotta get the new blog up before I leave in the morning!

Alley, I bet you had a nice evening with the freshcut lawn,, the fine weather, and the swing!

Janet, I haven't seen a giraffe yet, so you are one up on me! :) Hope your weather cools off soon!

Great catch, Sandi! You certainly have the zoom feature down pat!

All quiet on the cams, dogs and volcanoes asleep, one raccoon at the feeder and one zebra at the watering hole.

The busiest cam is Milos .... the waves are building and bashing onto the beach!

Morning Ylee :-)

No new blog. I have too much work to do, and there's too much ground to cover in order to do a proper job for the new blog. I'm afraid you all are stuck with these volcano cams for another week! :P

I apologize.

Here is a cam for the next blog:



It is the Greenpeace ship Esperanza.

Janet, Sandi, Alley, I apologize for not replying individually, just glad you came by!

I saw a Greenship in Honk Kong, my hotel room faced the port. The ship had to remain in the middle of the port and could not dock, if they did dock the police were ready to arrest the people on the ship! It was quite a scene... I never found out what happened next, I was deadly sick while in that hotel room and then we flew home. Next time I travel to that part of the world I am bringing astronaut food!

Morning to you,
All quiet on the cams, no one at the feeder nor the watering hole. Volcanoes and puppies asleep. Fog in Raoul, surf in Milos and rain clouds building on the Savannah :)

Good morning Ylee...one person standing on the beach on the Milos cam, otherwise not much on the cams to see. Pups are inside as its raining and fog and low cloud cover hides some volcanoes. Others are just too dark to see anything. Oh well. Guess I need to get up earlier and turn on the computer to see anything.

Watched a movie on Netflix last night until 2 AM...gotta stop that and sleep instead....LOL

Have a great day dear one.

Good evening! I'm back for one more night! I did work the previous two nights, but I had no computer access! This is just a basic connection, so unless I can spend some quality hours in the supervisors' office, no work on the new blog will be done!

We had a light shower late this afternoon; otherwise the weather has been really nice!

Pros, I don't think the Greenpeace ships gets much respect worldwide; you have to be totally dedicated to do what they do!

Hi, Sandi, Tony, and Todd! Thanks for keeping the blog afloat!

Hi, Alley! I've been up at 2AM the past four nights, but of course, I have to, lol!

GG, hope you are having a good week at the batcave!

ycd, what kind of browser do you have that enables you to hear webcam sounds? And of all things to hear....;-)

Hi, Janet! Glad you got to see the Far East cams before I change them this weekend! I hope! :)

Trauma! Looks like the new joint means more work than play; are you working 16 tonight? That's one of my old tricks, lol!

I hope you've got your eyes on Issac; I don't know what's up his sleeve, but it probably ain't good! :(

All quiet on the cams, even the sea in Milos has calmed down!
PS - Lovely capture of the moon over Kilauea :)

Good early morning Ylee. Its still 10 min to 4 AM. Just put food out for the kitties and thought I would pop on here for a moment to see if you were around. Sounds like work is really getting busy there for you. Hopefully things will be better soon.

Have a great morning dear one, get some rest after a bit to eat when you get home. I will probably head to bed soon too.

Good morning! Things are starting to warm up here, with highs approaching 90! Still cool in the mornings, so it's not too bad!

Work continues on the new blog; actually found one at home I may use on the blog! Ironically, it's from a .gov website!

Thanks for the bump, Janet! Lack of new cams are keping people away from the blog, I think! I'll fix that soon!

Moon over Kiluaea? Sandi, you catch all the cool shots! Hopefully, the new blog will give you more opportunities!

Alley, I fuss over working mega hours sometimes. but the extra money helps pay off extra debt, and I stockpile some to help us get through lean times. I was laid off for most of 2009, and I feel another one is not IF, but WHEN(Things are fine now, but it was also fine in '08), so every extra dollar I earn now I won't need when it gets bad.

Hope you get some rest!

Hi Ylee, the cameras are still cool if I can catch them in the morning. I think like you the problem with getting around to the blogs is time.

Time seems to have shrunk again. I've only been able to get to two or three blogs a day lately.
The parakeet is still coming by. Have been trying to get him used to me. Am hoping to get the skittish guy coming to me before the cold gets here.

Came up for some air; I think I'm at eight or nine cams at the moment. Need one more Far East cam to complete the set!

GG, at the moment, new blogs are hard to do because of all the cams available now. Before I started using WU cams, I had only a few hundred cams to choose from. Using WU cams added around 4500, and now in Glitch mode, another 10k+! Before, I had an idea of where to go for what type of cam I wanted. Now, it's a lot more work to search. In time, I'll be better able to find what I'm looking for, and blogmaking won't be as time consuming!

Maybe your little budgie friend was mistreated by its' former owners, and don't trust humans. It may be a challenge to get him on your side!

Rob, if it dropped down to 48 tonight down there, the main would be full of posts about the next ice age, and Mayans! :)

Hi, Ylee...

Maybe I'll have more luck with a new set of cams.

Seems like everytime I'd come by, nothing was happening. Even the pups have all been sacked out.

I whine about how involved it is to come up with ideas for a good blog, do the research and write it up. I need some cheese with that whine. You have bigger obstacles to doing a new blog, than I do.

Mine is just laziness!

Point taken. They don't need anything else to fight about over there. I've tried to keep up but it makes my brain hurt and my blood pressure rise.

It's like this:

Nope.
Nope.
Nope.
Yuck!
Nope.
Nope.
What the heck is that?

Why did they even bother?

all good views tonight, I'm a little more early than usual in coming by maybe that is why I'm getting all good ones (except for the watering hole: understand that so no biggy)
I had forgotten about those 2 am feedings, new kitty reminded me of them last night! I'm going to leave a bigger portion of food out at bedtime tonight.
We had a 3 hour round trip in the RV today. Was suppose to get the generator repaired but before we got there the one and only techie had an emergency call. At least they were generous enough to give us a $100. discount on the future billing.
Looking forward to the future cams

Hi, Janet! At least you had three hours in the RV! :) Maybe the discount will at least pay for your fuel and food!

Didn't find the cam I want; well, I did, but I can't use it here! :(

Good morning Ylee....Starting to heat up here in SW Ontario. Looks like we will be back into the high 80s this wknd with humidex near l00F. Not happy but I guess it was due after all it is still Aug. So looking forward to Sept and cooler temps coming to stay. I have been liking these 70s way too much...

Anyway have a great day. Good luck with your new blog.

Good morning! Going to be a pretty toasty day, with temps in the low 90s!

I'm going to work on the new blog framework, as I have everything I need except one cam. I'll get one this afternoon, plug it in the new blog, and post the whole thing before I go home tonight! At least that's the plan, lol!

Good morning, Alley! I'm sweating already, and it's not even 9AM yet! I'm already hitting the ice water! :)
