Why did Mt. St. Helens erupt sideways? The reason for that sideways explosion, Malone said, was that the magma within the volcano rose to the top asymmetrically. It’s likely that this happened because the magma followed pathways within the volcano that had been carved by previous eruptions many years ago.
Does Mt. St. Helens still smoke?

Will Yellowstone ever erupt?
Although another catastrophic eruption at Yellowstone is possible, scientists are not convinced that one will ever happen. The rhyolite magma chamber beneath Yellowstone is only 5-15% molten (the rest is solidified but still hot), so it is unclear if there is even enough magma beneath the caldera to feed an eruption.
Is Yellowstone active volcano?
Is Yellowstone’s volcano still active? Yes. The park’s many hydrothermal features attest to the heat still beneath this area. Earthquakes—700 to 3,000 per year— also reveal activity below ground.
What will happen if Yellowstone erupts?
The enormous amount of volcanic material in the atmosphere would subsequently rain down toxic ash; across the entire US, but principally in the Northwest. The ash would also kill plants, animals, crush buildings with its weight, block freeways, and ruin the country’s farmland for a generation.
