🌋 Think a quiet volcano is a safe volcano? Think again.
Some of the most damaging volcanic eruptions come from volcanoes that have been silent for decades — or even centuries. These so-called “dormant” or hidden volcanoes often erupt with little warning, catching communities and authorities completely off guard.
So why are quiet volcanoes so risky?
🔍 Less monitoring:
Fewer than half of the world’s active volcanoes are monitored. Research and resources tend to focus on a small number of high-profile volcanoes, leaving many others overlooked.
⚠️ Lower risk perception:
When a volcano hasn’t erupted in generations, it’s easy to assume it never will — until it does.
Together, these blind spots lead to reactive disaster response, where investment in monitoring and preparedness comes only after an eruption.
🌋 Volcano preparedness must be proactive.
Even the quietest volcano sends warning signals — we just need to listen, invest, and act before disaster strikes.
