The volcanic explosion in Tonga destroyed an island—and created many mysteries

Barker and his colleagues chartered a boat in 2015 to camp for several nights on the volcanic island’s rubbly landscape. As they surveyed the region and collected samples of rock, the team spotted small cones from recent eruptions dotting the seafloor around the primary peak. They also discovered thick layers of fragmented lava rocks and ash, known as pyroclastic flows, from two monstrous eruptions that they later dated to around 900 and 1,800 years old.

Scientists are now hoping to study the chemistry of the freshly erupted rock to see what it can tell us about this latest event."It'll be interesting to see what the crystals are recording," Brenna says.

"It basically had a very low decay of tsunami size all around the Pacific, which is really, really unusual," Kilgour says. The shockwave that traveled through the air could have coupled with the sea surface, driving the expansive tsunamis.

I saw radar of a missle floating around on the internet. Then I saw the blast pattern matching as such.

We heard the sonic boom in nz

Sad!

Rapharl_musn Correct

My theory is that the eruption was a reaction to the asteroid that passed us by around the same time.

Tried to read the article but y'all make that impossible, thats the last time I I'll be visiting your site

Where’s the missle?

Yeah from wut I read in other articles. Its strange.

We seem to be getting more volcanic eruptions these days

Nature calamity

We all must be glad it wasn't one of the volcanoes in the Americas or Europe.

Scary

Prayers for all affected.

You better study it. More are on the way...

Spectacular image, mother nature is amazing. Tonga

Krakatoa did the same thing

This one was pretty weak in comparison to other eruptions in the past which wiped out entire civilizations.

Twitter used to be where you could read articles from many sources. Now everyone wants you to at least sign up for their email deluge. i miss the old days.
