Imagine a world where we could predict the fury of nature before it strikes. That's the ambitious goal of researchers studying the 'twin threats' of Taupō, a region in New Zealand that's home to a supervolcano and frequent earthquakes. Their work could revolutionize how we prepare for future disasters.
Deep beneath the surface, in a seemingly ordinary trench on a quiet farm, lies a remarkable timeline. Layers of soil reveal a history of eruptions spanning millennia, offering clues about how the region's numerous fault lines have ruptured over time. But what's the connection between these geological events? Researchers are meticulously examining the relationship between supervolcanoes and earthquakes, seeking to understand if one influences the other.
While we understand that volcanoes erupt due to the build-up of pressure, forcing molten rock upwards, the role of earthquakes and tectonic shifts is less clear. But here's where it gets controversial: Can earthquakes trigger large volcanic eruptions? Do they precede them, occur during them, or follow them? These are the critical questions researchers, like lead scientist James Muirhead from the University of Auckland, are trying to answer.
Taupō is one of approximately 20 to 40 supervolcanoes on Earth. Its last eruption, 1,800 years ago, was the most violent known worldwide in the past 5,000 years. The study reveals that before, during, and after that eruption, the area's fault lines became active, showing significant movement. Understanding this relationship could offer vital clues about what triggers eruptions, allowing for better planning and response to hazardous events.
Although the probability of a future eruption at Taupō is considered low, the risk remains. The Natural Hazards Commission is funding this crucial research to raise awareness and ensure communities are prepared. As Jo Horrocks, chief research and resilience officer, points out, "There are so many things we can do to prepare and be ready for these things so that they don't have to be these major disasters where the community is severely affected."
