Not trying to mean,but there Is a differnce between bravery and foolishness-bravery imo would be if you rushed in to try and rescue someone from,say,an attack by a rabid dog,or a house on fire.No one's life depends on whether someone films some pyroclastic flow,just saying,you know? And to put yourself in harm's way for something inconsequential is more foolhardy than brave,imo. reply to: PlanetXisHERE
A pyroclastic flow (also known scientifically as a pyroclastic density current) is a fast-moving current of hot gas and rock (collectively known as tephra), which reaches speeds moving away from a volcano of up to 700 km/h (450 mph). The gas can reach temperatures of about 1,000 °C (1,830 °F). Pyroclastic flows normally hug the ground and travel downhill, or spread laterally under gravity. Their speed depends upon the density of the current, the volcanic output rate, and the gradient of the slope. They are a common and devastating result of certain explosive volcanic eruptions.
Climbers film as they are covered by ash cloud on an erupting volcano Mount Ontake
A group of climbers filmed themselves running for their lives after being caught on a volcano when it unexpectedly erupted.
Several climbers were scaling Mount Ontake in Japan this morning when it suddenly erupted, injuring at least eight people and leaving another 250 stranded near the peak, Japan Times reports.
One group were filming as they tried to flee the approaching ash cloud before it engulfed them.
The hiker who posted the video said the team managed to find shelter in a nearby hut, and local officials report that no one was killed due to the eruption.
However several commenters have expressed fear that the thick cloud of hot ash could do serious damage to hikers’ lungs.
Huichi Mukai, who runs a mountain lodge near the summit of Mount Ontake, said: ‘There was a thunderlike noise and the sky became dark because of the smoke.
‘There is now 15cm of ash on the ground.’
Mount Ontake, which sits in the centre of the Japanese islands, roughly 200km West of Tokyo, experienced its last major eruption in 1979 and is Japan’s second largest volcano.

Isn't a pyroclastic flow any kind of eruption coming from the volcano that doesn't travel upwards? I thought that was the distinction, ash/cinder clouds travel vertically, pyroclastic flows travel close to the ground; not trying to argue, just learn the terminology.
