The two other volcanos Hakla and Katla nearby are becoming very active. It will be very interesting on Iceland in next few days. I was thinking that it would mess up air travel more than it is now. But can you have less flights than zero?  |

Photos of lightning caused by electrical discharge within the ash column. Photos was taken by european volcanologist Marco Fulle.   The two other volcanos Hakla and Katla nearby are becoming very active. It will be very interesting on Iceland in next few days. Great find on the pics Aquatic! Volcanic lightning is awesome. Don't know of a better adjective. I could watch it that all day. Too bad there isn't a video of that. |

Interesting USA Today article: http://www.usatoday.com/tech/science/2010-04-19-1Avolcano19_CV_N.htmSnip from article: "When Katla went off in the 1700s, the USA suffered a very cold winter," says Gary Hufford, a scientist with the Alaska Region of the National Weather Service. "The Mississippi River froze just north of New Orleans, and the East Coast, especially New England, had an extremely cold winter. Depending on a new eruption, Katla could cause some serious weather changes." |

Let's not forget that Iceland has the Mid-Atlantic Ridge running right thru it.

History Channel is showing a "How The Earth Was Made" tonight and the topic is "Iceland Volcano". It wasn't recently made, but it's showing is timely. I tried to watch it, but the camera swinging and the picture speeding up and slowing down made me queasy. It's too bad. I'm sure it would be a good show. Too bad they had to ruin it with effects.  |

The eruption of Eyjafjallajokull is nothing compare to the Laki eruption 1783, it did kill 20-25% of the population on Iceland. Read more here http://en.wikipedia.org/wiki/Laki |

More and more news people are calling the volcano E=15. 15 is the number of letters after the letter E. I guess if you're not from Iceland, it's hard to pronounce. |

Here's a picture from Iceland. I don't think I would want to be driving behind another vehicle. Can just imagine what that volcanic dust would do to an engine. The air filter must clog up very quickly in such conditions. Dust in a camera would be another issue too...

Exactly what I was thinking when I saw that photo. Being such a fine powder I would think it would also make it's way around wheel bearing seals, ball joints, tie rod ends, any breathers on the differential, transfer case, engine crankcase, etc. What a mess that would be to have that dust laying all around like snow on the ground plugging drains and sifting into the house through every little crack. |

I can remember a few weeks after Mt St Helens blew in the 80's and I drove from Seattle back to San Jose. When we went through the area, there was ash everywhere and the dust clouds were horrendous on I-5 - although not as bad as in the picture I uploaded from Iceland. I was in a U-Haul truck and it was covered with extremely fine ash dust. We told the U-Haul dealer in San Jose we had been through the area and he said he would change the air filter right away. I collected a small baby jar full of the ash and still have it. It is extremely fine ash and feels very gritty when you put a little between your fingers. Guess that's why it's used in LAVA soap and other cleaning products.

I saw a program on TV sometime back, either "Air Emergency" or "Seconds From Disaster", that featured a story about a passenger jet that flew into volcanic ash. It was night and the pilots had no warning about the ash and they had no idea what was happening to them. Passengers saw flame like streamers emerging from the jets engines and the front surface of the wings were glowing! The engines started failing and the pilot decided to descend. When he did that the plane went below the ash and the engines came back to normal. Not knowing what had happened they returned to the higher altitude. That put them back into the ash. This time the pilot shut down the engines, I believe, and again he descended. Again, the engines started up and returned to normal. It took some time but they did find out what was happening by talking to someone on their radio. But, they were now blind   . They could not see out the front windscreens. They had been "sandblasted" by the ash particles!!! Whoa! I know they can land with instruments but it cannot be comfortable to not be able to see out the front of the plane!! Wish I could remember more about the incident. It was a great show. It will be on again. They show them pretty regular. |

The ash is back in the airspace over Ierland and UK.  |
