What's it like to visit a supervolcano? Are they safe to visit?

When one thinks of supervolcanoes, ideas such as end-of-world catastrophes, gigantic explosions, darkness caused by ash clouds covering the sun, and total madness come to mind. But scientifically speaking, how does one define a supervolcano? A supervolcano is a volcanic system that has the capability to produce eruptions that are graded as VEI 8 according to the Volcanic Explosivity Index.Paradoxically, despite their capacity for catastrophe, many of these extinct volcanoes rank among the most captivating tourist attractions available today. There are three volcanic calderas in particular that are renowned for both their geological importance and their appeal to tourists: the Yellowstone Caldera in America, the Toba Caldera in Indonesia, and the Taupō Caldera in New Zealand. Yellowstone Caldera is located under Yellowstone National Park, which is one of the busiest places for tourists in the world. A fun fact about Yellowstone National Park is that it is the oldest national park in the world. Yellowstone Caldera erupted around 640,000 years ago, although geologically, it is very active, judging from all the geothermal processes.What makes Yellowstone special is the visible evidence of geological activity under the Earth. Tourists get to witness geysers spewing water, steam vents, boiling mud pools, and beautiful hot springs. All of these natural wonders are a product of current geological processes and show the amount of energy currently trapped under the surface.There is an abundance of tourist infrastructure in Yellowstone. Visitors can observe the geothermal processes on boardwalks and at observation stations. At the same time, Yellowstone is home to huge wild areas that allow for wildlife watching and outdoor activities. Moreover, the whole system is regularly being monitored by the United States Geological Survey. The Toba Caldera is the result of one of the most powerful eruptions in Earth’s history, which occurred around 74,000 years ago. This event, classified as VEI 8, is believed to have had significant global climatic effects, possibly triggering a volcanic winter.Currently, the area is remarkably serene as the huge caldera is occupied by the beautiful Lake Toba, which is the largest volcanic lake in all of Southeast Asia. Within the lake, Samosir Island exists, home to the Batak people and their rich cultural traditions.Toba is renowned for relaxing vacations and cultural tourism. This place attracts tourists due to its spectacular scenery and milder weather. In contrast to Yellowstone, where there is much volcanic activity in the form of geysers, Toba looks rather dormant. The Taupō Caldera’s most significant eruption, the Oruanui event around 26,500 years ago, was one of the largest known eruptions in recent geological history. Now this caldera is covered by the huge Lake Taupō, which is a freshwater body and a dominant landmark on the central part of North Island.This area is known for its recreational activities such as boating, fishing, skydiving, and hiking. Geothermal parks nearby and attractions like Huka Falls add further interest. Taupo is amongst the major attractions for tourists in New Zealand, proving how a geographical feature that had come about because of severe geological activity can later become a major tourist destination.So to answer the big question – are these supervolcanoes safe to visit? Do these supervolcanoes post a danger to visitors? The answer, in practical terms, is no, at least not in the way people often imagine.These areas are under constant surveillance by scientific experts, and there are no signs of any immediate large eruptions taking place here. Supervolcanoes operate on very long scales of time and it will take several tens of thousands of years for a supervolcano eruption to take place.However, these places are not free of dangers as well. In the case of geothermal fields, it is necessary to take special precautions because of high temperature and unstable soils. It is recommended to comply with all safety measures and walk only on marked trails.Yellowstone National Park is an excellent example of how a supervolcano can be used for leisure purposes. It gives an opportunity to get acquainted with the geological activity of our planet and enjoy its amazing nature. Lake Toba can give travelers some time for reflection and relaxation against the backdrop of the beauty formed after a cataclysmic event. Finally, Taupō is the perfect place to combine volcanology and tourism.Thus, the three parks demonstrate one important principle: even such destructive and powerful forces as supervolcanoes can, in time, turn into a place that is both inhabitable and beautiful.
