Krakatoa: The Last Days, Clip 6 - Pyroclastic Surge

From the BBC docu-drama, "Krakatoa: The Last Days." The movie is also known as "Krakatoa: Volcano of Destruction" and aired on Discovery Channel. The movie brings to life the journals and recollections of four witnesses who survived the cataclysmic eruption of Krakatoa in August of 1883.

The Beijerinck (Beyerinck) family, along with 3,000 Ketimbang survivors, had settled further inland. They survived a tsunami and the destructive ear-shattering force of Krakatoa's explosions. They thought the worst had past, but one more is about to strike.

A pyroclastic surge is a fluid mass of turbulent gas and rock fragments which is ejected during volcanic eruptions and are similar to pyroclastic flows except that it has a higher proportion of gas to rock particles. Pyroclastic flows can generate pyroclastic surges. Because a pyroclastic surge is "lighter" than a pyroclastic flow, it can travel much faster at speeds of 350 mph carrying massive destructive kinetic energy and can actually climb higher ground.

Pyroclastic surges can be "hot" containing gas and steam at temperatures above 100 degrees Celsius (212 degrees Fahrenheit) to as much as 800 degrees Celsius(1472 degrees Fahrenheit). They can also be "cold" with temperatures below 100 degrees Celsius. Aside the temperature factor, both hot and cold pyroclastic surges can still be lethal, depending on the type of gases they carry.

Hot pyroclastic surges can cross significant bodies of water on a cushion of superheated steam just as it occurred in the Ketimbang area of Sumatra.

1:36.... "RARI RARI... CEPAT RARI SELAMAT DIRI???" that's not sound like indonesian.... that's malay...

[MelodyOfVision]

@molceonly - Yeah, other people have said that the language is wrong on this one. I'm starting to wonder where the BBC filmed this... Cute and adorable baby in the profile pic, by the way!

Victims in Herculaneum were carbonized a second after surge hit them, how come some of these people got away with only burns? It's not like they had a better cover than the people on Herculaneum beaches.

[MelodyOfVision]

Herculaneum was the closest town to Mt. Vesuvius. The pyroclastic flow that hit it was still very hot.

The Krakatoa surge had to travel 30 to 35 miles to the settlement over water and land. It cooled enough that 2/3rd of the people survived.

[MelodyOfVision]

@Athaeus - The BBC did such a fantastic job of making the Krakatoa event come alive for us that I wanted other people to know about it. I'm glad you appreciated their effort!

[penwinox]

No one survives a pyroclastic wave in real life!!! omg

THE BABY !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!­!

This hurts very ...

@moiceonly, well Malays originally came from Indonesian, peoples from West Sumatra and Celebes have found state there.

Based on Atlantic Book:Finally Found" written by Prof Arysio; Krakatoa had destroyed Atlantic when its first eruption, drowned the continent and remained "small" Islands that is Indonesia. The Eruption came back at 1883. The volcanoe died but 6 months later he came back as named "Anak Krakatoa". Its still active till today.

@MelodyOfVision yeah, i haven't check the store yet, but i believe those "malay" actor isn't quite an indonesian too... hahaha....

well, thank you, that's my baby girl KYRA... she is 15 months old now

And the award for mother of the year goes to...

@Malusregnum sad to say this movie use indonesian crew... what really happen is those islam rule not allowing them expose too many bare skins and gory scene. so to be honest, BBC made their best effort already to pronounce the detail pretty close to the real event.

don't stuck with the video, just realize the history mark it self what we can learn from this Mass Killer Mother Nature...
