I made a prediction about 6 months ago that Long Valley would erupt in two years. I don't think Long Valley will erupt in the next year. Big volcanoes, like Long Valley and Yellowstone, erupt less frequently than smaller stratovolcanoes. Periods between major eruptions are in tens or even hundreds of thousands of years. I think the level of activity before the next major eruption will be far more intense then any observed to date.
Long Valley is a well monitored and studied volcano.
You can revise your prediction then.
