Wow looked huge!

About 10 seconds from explosion visual until sound / shock wave hit the boat means about 3km distance, which is a lot closer than I'd want to be to an exploding volcano.

I agree, wow. Amazing to see the shock wave rushing down the hill, turning it brown.

I sort of expected the shock wave to be visible on the water as it approached the boat. You can usually see a wind shift approaching clear as a bell, but I guess that most of the energy was not down at the surface level.

that was one of the coolest videos i've ever seen. amazing to see water condensing as the shockwave passes.

Check out the size of some of the boulders that were flung into the air, and the splashes they made coming down. Given the 3 km distance you could probably figure out the actual size if you weren't as lazy as me. I'll just go with very freaking large. Like the size of an office building large.

Yeah isn't this that volcano that will cause a mega tsunami for the east coast of the US when half of the mountain slides into the ocean?

Damn amazing. The size of those boulders hitting the water...they must have been massive.

It looked to me like some of the larger chunks landed up to a kilometer away from the cone. The forces at work can really only be understood through mathematics or observation of effects. I can't put them in any sort of context.

Guinea.

Won't someone please think of the guinea pigs?

I recently learned that Peruvians eat guinea pigs at their version of Thanksgiving. Source: my Peruvian friend who was visiting another friend who had pet guinea pigs and said "hey, dinner!" :biggrin:

Yea, the shape of the mountain's ridge appeared to deflect the majority of the shock-wave upwards. One has to wonder what the experience would be if you were in an airplane above that area when that exploded, I guess by the time it got to 33Kft it would have dissipated a lot but possibly still strong enough to give the airframe a solid, loud thump and a lot of stained underwear LOL. Thanks for posting, bumped up to HD and full-screen it's amazing..

EDIT:..I found this site that has a NASA satellite view of before/after the explosion, also another video taken from a sailboat also near the area, http://www.washingtonpost.com/blogs/capital-weather-gang/wp/2014/09/03/nasa-satellite-captures-incredible-extent-of-tavurvur-volcano-ashfall/
