Answer:
Mount St. Helens is a spring of gushing lava that ejected with incredible power in 1980.
Explanation:
The best expression which supports the ejection would be high-consistency magma broken into sections. In the time of 1980, there was a significant volcanic emission experienced which was activated by a tremor.
The occasion occurred under the zone of the north face where Mount St. Helens is found.
The emission was tremendous to such an extent that after the blast there was immense dispersing of debris which spread to neighboring states.
