Meanings of new magma in English

The increased sulfur dioxide would additionally suggest new magma in the volcano.

More interestingly, these early ash analyses suggest that little to no juvenile ( new magma) material present.

This depends on whether magma is ascending under the crater - new magma means that more eruptions could occur.

Earlier this year, a study of the summit crater lake suggested new magma was intruding under Copahue and the SERNAGEOMIN report mentioned.

As lava domes form, they can be destroyed by gravitational collapse or by an explosion underneath the dome caused by new magma intruded.

Combine that with volcanic tremors and increased gas output, then it is pretty clear we have new magma working its way up the system.

There isn't an increase in gas emissions like carbon dioxide or sulfur dioxide as little-to-no new magma is rising in the volcano releasing these gases.

This explosion then produces ash clouds and pyroclastic flows made mostly of the shattered debris of old rock at the crater rather than new magma.
