phreatomagmatic

If magma is directly involved, they would then become phreatomagmatic.

If magma is included, the term phreatomagmatic may be used.

Although similar in nature to phreatomagmatic eruptions, there are several specific characteristics:

The Rodderberg detonated in a phreatomagmatic eruption about 250,000 years ago.

This is a result of the much higher fragmentation of phreatomagmatic eruptions.

It is very common for a large explosive eruption to have magmatic and phreatomagmatic components.

Only at the Hoyo Negro did any phreatomagmatic activity occur.

The most recent activity includes lava flows along with strombolian and phreatomagmatic explosions.

A hydrothermally altered area in the middle of the caldera has been linked to phreatomagmatic activity.

Phreatomagmatic ash is formed by the same mechanisms across a wide range of compositions, basic and acidic.

The eruptions of Chascon initially were phreatomagmatic and influenced by local lakewaters.

Volcanic ash is also produced during phreatomagmatic eruptions.

Phases 1 and 3 were phreatomagmatic.

Maar: a depression resulting from phreatomagmatic eruption or diatreme explosion.

If molten magma is included, it is classified as a phreatomagmatic eruption.

Gour de Tazenat is a volcanic crater formed by a phreatomagmatic eruption.

These were later overlaid with brown pumice and bombs from a later phreatomagmatic eruption.

The eruptions from El Jorullo were primarily phreatic and phreatomagmatic.

The most recent activity is thought to have been phreatomagmatic explosions around 40 ka ago which produced maars and small cold surges.

The bombs have a cauliflower shape, typical of phreatomagmatic eruptions due to fissures created by contact with water.

As the eruption proceeds, eruptions typically become phreatomagmatic (explosive), generating hyaloclastite.

The eruption resumed with phreatomagmatic activity that deposited the Rotongaio Ash.

Many of the cinder cones on Tenerife are believed to be phreatomagmatic because of these circumstances.

Phreatomagmatic eruptions are eruptions that arise from interactions between water and magma.

Phreatomagmatic eruptions occasionally create broad, low-relief volcanic craters called maars.
