Which of the following events did not occur during both the mt. st. helens and kilauea eruptions? a. a large magnitude earthquake b. a large landslide-type collapse c. a lateral volcanic blast d. emptying of magma from a buried magma chamber

The right answer is:

A large magnitude earthquake.

Explanation:

The earthquake did not occur during the eruption (that´s the question being made here). The earthquake that struck the northern face of Mount St. Helen on May 18, 1980 triggered both the largest landslide in recorded history and the volcanic eruption. No earthquake is associated with the event of the Kilauea.
