One scenario is that the Strombolian activity would transform into a Vulcanian
activity just like in the 1968, 1984, 2000 and 2001 eruptions after a visual lull in Mayon's activities.
explosion in which fragments of the overlying rock and of the disrupted magma are scattered around the explosion source: This is called Vulcanian activity (Fig.
In the Elysium region of Mars, a large, water-carved channel, Hrad Vallis, has a complex elongate source depression that appears to have been excavated by a Vulcanian explosion when a dike injected a sill into the ice-rich permafrost of the cryosphere--the outer several kilometers of the crust, which is so cold that any H[sub.
A Vulcanian explosion on Venus would also be very different from its equivalent on Earth.
The characteristics that Mayon is showing are [those] of a vulcanian eruption, or maybe even a strombolian eruption," Director Renato Solidum of the Philippine Institute of Volcanology and Seismology (Phivolcs) told reporters on Monday.
A vulcanian eruption is characterized by strong explosions, multiple pyroclastic flows or a fastmoving mix of hot gas and rocks, and lava cascading down the volcano slopes.
He said that in a vulcanian eruption, the swiftly moving hot gas and rocks could reach a radius of six kilometers from the crater while the ash fall could reach within a radius of 10 km.
