Earth's Largest Caldera; 150 Kilometers Wide

Calderas often form during the largest explosive or effusive eruptions. So, what is Earth's largest caldera? The answer is now Yellowstone, Taupo, or even Toba. Rather, a little known 93 mile or 150 kilometer wide caldera exists off the eastern coast of the Philippines; the Apolaki Caldera. Luckily, the Apolaki caldera is long extinct and will never erupt again. #volcano #philippines #geology #caldera #shorts #short

I would love to see you do some videos on Large Igneous Provinces like the Siberian Traps. They represent some of the most extreme volcanism in our planet's history.

[BlackCeII]

I am studying volcanology extensively, and I've never heard such a perfect concise explanation of a Caldera that is intuitive as you just presented. Well done. I love and like every one of your videos

[kwgm]

Ah, but Crater Lake, Oregon might be the most beautiful.

Wondering how big the tsunami was when the colasped off the Philippines.

Apolaki in the Filipino language means "Big/Giant Lord"

I'm suddenly curious about how a caldera collapse would look on a seismograph.

[dojoswitzer]

Would such a large collapsing be sudden or incremental? If sudden, then over what time? What would be the speculated size of the resulting tsunami?

[GearGuardianGaming]

Imagine the tsunami that made if it all collapsed at once...yikes

The funny thing about the Apolaki Caldera is that there is a very tall and thin point that's higher than the rim of the caldera which is the Benham Rise.
Imagine the sheer height of the thing if it popped up the surface.

Thanks for adding New Zealand's Taupo volcano - can you perform a study on the history of Taupo's recent eruptions - around 2000? yrs ago- quite recent as far as stratosphere volcanoes go! Noticed in the Chinese records with darkened skies for 3 years. Part of an Ice age in the Earth.

The newest caldera is the large Hunga Tonga-Hunga Huapai eruption caldera

I'm a Filipino myself and I have something to tell to most people
Apo - Largest Mountain in the Philippines
Laki - Big

Mount saint helens never collapsed into a calerera i heard

[Country_humans_philippines]

how do you even make a size of the caldera

[nkronert]

I always wonder how it could happen that a magma chamber gets "emptied" like that. I would think you'd need over-pressure to push out the lava elsewhere. Or an opening much lower than the top of the magma chamber so the molten material just flows out under gravity.
What fills the void? Volcanic gases? Or is it that the rock above the still full chamber becomes unstable and collapses, in the process "squirting" out an eruption elsewhere?

The Submarine Caldera of Indonesia 🇮🇩 Active Volcano 🌋 Mount Krakatoa which Exploded and sank into the Sunda Strauts in 1883 explosion Eruption.

You should do a video on the Wah Wah Caldera in Utah. It’s magma chamber is 30 times larger than the one under Yellowstone.

[Growgreen]

Apparently the apologies caldera is currently inactive so it might erupt again and if it does it will cause the tectonic plate with the Mariana Trench ( I don’t know the name of it so) it will break it apart causing so many new islands and big islands in the philippines

[scratchingcatclaw]

Can't imagine the size of the eruption that birthed the existence of this caldera

[Itsjustme-Justme]

That thing must have created one hell of a tsunami
