The year after Mt. St. Helens erupted (1981), farmers, orchardists and vintners, in the Yakima Valley, had a bumper crop of whatever they were growing. On a smaller scale, our garden was extremely prolific. Geologists told us that the soil became extra-fertile because of the ash and silicone from the volcano. That's from personal experience.
On a world-wide scale, eruptions take pressure off and keeps another super volcano from erupting and causing mass extinction.
