Unless you are an airline executive or a stranded traveler, here are a couple neat videos of Iceland volcano Eyjafjallajokull. This first video is from a helicopter near the volcanic plume. Midway through the footage, you'll see lava bombs firing out from the left side of the ash cloud. The journalist on board keeps talking about seeing lightning, but I'm not seeing it in this video capture.

This second video is an animated map showing the path of the volcanic ash's path over Europe. The color coding of the video breaks down this way: yellow indicates ash that has fallen by itself; red is ash that has fallen as a result of precipitation, black is where the ash cloud is at that moment in time.

Eruption photo: Here is the volcano at full eruption mode in an image taken Saturday, April 17, 2010.Courtesy Paul Morin, Antarctic Geospatial Information Center Department of Geology and Geophysics University of MinnesotaFinally, here are a couple of satellite images of the coast of Iceland where the volcano is located. The first photo was taken before the eruption. The second photo on Saturday, April 17. Click on each image to get a much larger view of what's happening, or not happening, in each photograph.

And here is an informative article that lays out the best case, worst case and in-between case scenarios that could play out from Iceland's volcanic activities. It also talks about how air traffic has been diverted around past volcanic blasts and what makes this situation so different.
