The pulverized particulates are called ash. Larger chunks of magma are called tephra.

Volcanic particles about the size of rice grains are called volcanic ash. Ash is made up of small rock and mineral fragments that are expelled during a volcanic eruption.
The cloud of ash, gas, and rock fragments that is produced during a volcanic eruption is called a volcanic plume or eruption cloud.
An eruption.
They are called fragments, fragments.
Tephra refers to any airborne particles from a volcanic eruption, and includes pumice, cinders, dust, and ash. Ash refers to particles smaller than 2 mm, and volcanic dust particles are less than 0.06 mm in diameter. Volcanic blocks, also known as bombs, are the largest pieces of tephra and are more than 64 mm in diameter (baseball size or larger) and may be as large as small cars.
i think eruption
Pyroclastic material consists of fragments of rocks that forms during a volcanic eruption. Pyroclastic particles that are less than 2mm in diameter are called Volcanic Ash. Volcanic ash that are less than o.25 mm in diameter is called volcanic Dust. Large Pyroclastic particles that are less than 64 mm in diameter are called Lapilli
No. Pebble-sized particles from a volcano are called lapilli. Ash is sand-sized or smaller.
when volcanic ash bursts out of the volcano, its called an eruption.^^^Actually, when ash and cinders are blown violently out of volcanoes, it's called a tephra. :3
it is called a volcanic eruption
Large volcanoes that rise from the sea floor are called seamounts or underwater volcanoes. These formations are created by volcanic activity beneath the ocean's surface and can vary in size and shape.
