Observe the Photograph of an Entire Forest of Trees Knocked

Observe the photograph of an entire forest of trees knocked down on Mt. St. Helens. By contrast this is not the case on Kilauea. Why were so many trees knocked down during the Mt. St. Helens eruption while that was not true o Kilauea volcano?

A) The force of the blast at Kilauea vaporized all the trees, as Hawaiian volcanoes are significantly more powerful than Mt. St. Helens.
B) The force of the blast from Mt. St. Helens caused the trees to be knocked over, while the Kilauea volcano was much less violent.
C) The difference is that Mt. St. Helens produced a lot more ash, and the weight of the ash caused the trees to topple over after a few days.
D) Every volcanic eruption knocks down trees. There are no trees in Hawaii but there trees are near Mt. St. Helens, so that explains the difference.
