The more recent craters/volcanoes of the island of Nisyros

The Nisyros Caldera, a geological wonder formed by volcanic activity over thousands of years, is home to a series of intriguing craters scattered around the island. Located just a few hundred meters away from the prominent Stefanos Volcano, these craters offer a fascinating glimpse into the island’s volcanic past and present. Each of these more recent craters has its own distinct character and name, such as Big Polivotis, Polivotis, and Alexandros, among others. They add to the island’s rich tapestry of volcanic features and provide visitors with an opportunity to explore lesser-known, yet equally captivating, aspects of Nisyros’s volcanic landscape.

The Craters and Their Activity

The craters around the Nisyros Caldera represent some of the more recent volcanic activity on the island. While the Stefanos Volcano is the most famous and accessible of Nisyros’s volcanic features, these craters each have their own unique story. Some of these more recent craters have experienced volcanic activity as recently as the late 19th century, making them relatively young in geological terms. This recent activity contributes to their distinctive characteristics, including vivid colors and active fumaroles.

• Big Polivotis: One of the most striking craters in the caldera, Big Polivotis is known for its impressive size and the vivid hues of its mineral deposits. The fumaroles in this area emit plumes of steam and gases, creating a dramatic visual effect against the stark, volcanic landscape.
• Polivotis: This crater is another notable feature within the caldera, offering visitors a chance to witness the ongoing volcanic processes that shape the island. The surrounding terrain is marked by vibrant colors and geothermal activity, making it a compelling site for exploration.
• Alexandros: Named after a local figure or perhaps a historical reference, the Alexandros Crater adds to the diversity of volcanic features on Nisyros. Its unique characteristics, including fumarolic activity and colorful mineral deposits, contribute to the overall intrigue of the caldera.

Challenges and Rewards of Visiting

While these craters offer a wealth of geological and visual interest, accessing them can be more challenging compared to the well-trodden paths to Stefanos. The rugged terrain and the presence of active geothermal features mean that reaching some of these craters requires careful planning and preparation.

• Accessibility: Unlike Stefanos, where visitors can walk to the bottom of the crater along a designated path, many of the more recent craters are not easily accessible. Some of them can only be viewed from a distance, as getting close to the crater rims or attempting to reach the crater floors may be hazardous due to unstable ground, high temperatures, or steam emissions.
• Safety Considerations: Visitors should exercise caution when exploring these areas. The geothermal activity, including fumaroles and hot springs, can create dangerous conditions. It is essential to follow safety guidelines, stick to marked trails if available, and consider guided tours for a safer experience.

The Experience of Visiting

Despite the challenges, visiting the more recent craters of Nisyros is a rewarding experience for those interested in volcanic geology and natural beauty. The craters’ wild, untamed landscapes offer a stark contrast to the more developed areas of the island. The vivid colors of the mineral deposits, ranging from bright yellows and oranges to deep reds and greens, create a surreal and otherworldly atmosphere. The abundant fumes and steam add to the dramatic effect, making these sites particularly atmospheric and photogenic.

The sense of isolation and the raw power of the volcanic activity contribute to the craters’ allure. For those who venture off the beaten path, the experience of standing amid the remnants of recent volcanic activity provides a profound connection to the dynamic forces shaping Nisyros.

Conclusion

The recent craters of the Nisyros Caldera, including Big Polivotis, Polivotis, and Alexandros, are remarkable features that offer insight into the island’s volcanic history and present-day geothermal activity. While they may be less accessible and require more effort to visit, the wild beauty, vivid colors, and active fumaroles make these craters a compelling destination for adventurous travelers and geology enthusiasts. Exploring these sites provides a deeper understanding of Nisyros’s volcanic landscape and a memorable experience amid the dramatic scenery of this Greek island.
