What caused the 2014 eruption of Mount Tavurvur in Papua New Guinea?

[Astronuc]

Mt. Tavurvur, located near the town of Rabaul in the eastern region of Papua New Guinea, has erupted again.

Some folks have captured video and images of the eruption.

Tavuvur is a pyroclastic shield volcano.

The low-lying Rabaul caldera on the tip of the Gazelle Peninsula at the NE end of New Britain forms a broad sheltered harbor utilized by what was the island's largest city prior to a major eruption in 1994. The outer flanks of the 688-m-high asymmetrical pyroclastic shield volcano are formed by thick pyroclastic-flow deposits. The 8 x 14 km caldera is widely breached on the east, where its floor is flooded by Blanche Bay and was formed about 1400 years ago. An earlier caldera-forming eruption about 7100 years ago is now considered to have originated from Tavui caldera, offshore to the north. Three small stratovolcanoes lie outside the northern and NE caldera rims of Rabaul. Post-caldera eruptions built basaltic-to-dacitic pyroclastic cones on the caldera floor near the NE and western caldera walls.

Nice! :thumbs:

 

[davenn]

awesome

I wonder why only some eruptions like that produce such an intense shockwave ?

this one at Anak Krakatau didn't with any of its explosive bursts...

http://www.youtube.com/watch?feature=player_embedded&v=DPchWu5GB4MHaven't figured out how to embed the video Dave

You just need to put the v= section into the YOUTUBE tags (DPchWu5GB4M for yours). Don't include anything else like &t=. On the advanced tab, it's the one that looks like a TV. You can also quote another post that has embedded a video to see how it looks.
