Multi-Signal Decoupling Insight
The "Countdown" Myth: Earthquakes alone do not equal an eruption. If conduit pathways are open and gas freely vents, huge earthquake swarms often stall harmlessly. Conversely, a deadly sealed volcano may show zero gas emissions while building fatal phreatic pressure.
