Volcanoes are among nature’s most awe-inspiring and dangerous features, capable of reshaping landscapes and lives in an instant. Yet, millions of people around the world choose to live in their shadows, drawn by fertile soils, economic opportunities, and deep cultural ties. This article explores the towns built on volcanic slopes, delving into why people settle in such precarious locations, the risks they face, the lessons learned from history, and the cultural significance of these fiery giants. From Naples to Bandung, these communities balance the rewards and dangers of living with lava.
Why Live Near Volcanoes?
Living near a volcano might seem like a risky choice, but the benefits often outweigh the dangers for many communities. These advantages, rooted in the unique properties of volcanic environments, have drawn people to these areas for centuries.
Fertile Soil for Agriculture
Volcanic ash and rock are rich in minerals like magnesium and potassium, which weather into highly fertile soils. When ash falls, it acts as a natural fertilizer, boosting crop yields. For example, around Mount Etna in Italy, farmers cultivate grapes, olives, and citrus fruits, benefiting from some of the most productive agricultural land in the region. In Indonesia, near Mount Merapi, farmers have adapted their practices to different types of ash, ensuring robust harvests even after eruptions. Volcanic soils are also porous, retaining moisture longer than many other soil types, which supports agriculture in diverse climates.
Geothermal Energy
Volcanoes provide access to geothermal energy, a renewable and reliable power source derived from the Earth’s internal heat. Countries like Iceland and New Zealand lead in geothermal energy production, using it to generate electricity and heat homes. In California, The Geysers geothermal plant, located in a volcanic region, produces enough electricity to power a city the size of San Francisco. In Indonesia, geothermal power plants near volcanoes supply energy to local communities, reducing reliance on fossil fuels and providing a sustainable energy source.
Tourism and Economic Benefits
Volcanoes attract millions of tourists each year, drawn by their dramatic landscapes, hot springs, and the thrill of witnessing nature’s power. This tourism boosts local economies, creating jobs in hospitality, guiding, and retail. For instance, Yellowstone National Park in the United States, with its geysers and volcanic features, draws millions of visitors annually. In Bandung, Indonesia, Tangkuban Perahu volcano is a popular day trip destination, where tourists can drive to the crater rim and experience steaming vents and hot springs, significantly contributing to the local economy.
Cultural and Spiritual Significance
Volcanoes often hold deep cultural and spiritual meaning for nearby communities. In Japan, Mount Fuji is a national symbol and a sacred site of pilgrimage, revered in art, literature, and religion. In Hawaii, volcanoes are associated with Pele, the goddess of fire, and are treated with profound respect. These cultural connections foster a sense of identity and belonging, making volcanoes integral to the communities that live near them.
Historical and Community Ties
Many volcanic regions have been inhabited for centuries, with residents forming deep emotional and economic ties to the land. In Naples, Italy, the city has grown around Mount Vesuvius, and despite its history of destructive eruptions, the area remains densely populated due to its historical significance and the resilience of its people. Moving away is often not a practical or desirable option for those with generational roots in these areas.

| Quito | Ecuador | Cotopaxi | UNESCO World Heritage site, tourism | Mudflows (lahars), seismic activity |
| Arequipa | Peru | El Misti | “White City” built from volcanic rock | Potential for Pompeii-like eruption |
| Bandung | Indonesia | Tangkuban Perahu | Tourism, cultural festivals | Phreatic eruptions, seismic activity |
Naples, Italy
Naples, home to over 3 million people, sits in the shadow of Mount Vesuvius and the Campi Flegrei caldera. Vesuvius’s infamous 79 CE eruption buried Pompeii and Herculaneum, yet the region’s fertile soils and mild climate continue to attract residents. The city benefits from tourism, with millions visiting Vesuvius and nearby archaeological sites. Advanced monitoring by the Vesuvius Observatory and detailed evacuation plans help mitigate risks.
Kagoshima, Japan
Kagoshima lies across a bay from Sakurajima, one of Japan’s most active volcanoes, which frequently showers the city with ash. Residents have adapted with ash-cleaning infrastructure and use geothermal energy from the volcano. The city’s resilience and economic benefits from tourism make it a prime example of living with volcanic activity.
Catania, Italy
Located near Mount Etna, Catania uses lava rock for construction and benefits from fertile soils that support vineyards and orchards. Etna’s frequent eruptions pose risks, but early warning systems and community preparedness help manage these challenges.
Goma, Democratic Republic of Congo
Goma, near Mount Nyiragongo, has faced devastating eruptions in 2002 and 2021, which destroyed parts of the city. Despite these risks, Goma remains an economic hub due to its strategic location and fertile land, with ongoing efforts to improve disaster preparedness.
Puebla, Mexico
Puebla, near Popocatépetl, is a cultural and economic center. The volcano’s occasional ash falls require regular monitoring, but the region’s agricultural productivity and tourism keep it thriving.
Quito, Ecuador
Quito, Ecuador’s capital, lies near Cotopaxi, a stratovolcano known for its potential to cause mudflows if its ice cap melts. As a UNESCO World Heritage site, Quito’s colonial architecture and proximity to volcanic landscapes make it a cultural and tourist hub, though it faces significant risks from eruptions.
Arequipa, Peru
Arequipa, known as the “White City” for its buildings made of sillar (volcanic rock), is near El Misti, which last erupted in the 15th century but remains active. The city’s fertile land supports agriculture, and its cultural significance attracts tourists, though the potential for a major eruption looms.
Bandung, Indonesia
Bandung, in West Java, is surrounded by volcanoes, including Tangkuban Perahu, a popular tourist destination where visitors can drive to the crater rim. The volcano’s last eruption in 2019 was minor, but its activity underscores the need for vigilance. Bandung’s economy benefits from tourism and its vibrant cultural scene.
Historical Lessons from Volcanic Eruptions
The past offers critical lessons about the destructive power of volcanoes. The 79 CE eruption of Mount Vesuvius is a prime example, burying the Roman cities of Pompeii, Herculaneum, and Stabiae under ash and pumice. The eruption began with a massive Plinian column, followed by pyroclastic flows that engulfed the cities, preserving them as archaeological treasures but killing thousands. Excavations have revealed detailed insights into Roman life, but they also highlight the sudden devastation volcanoes can unleash.
Modern cities like Naples have learned from these events. The Italian National Institute of Geophysics and Volcanology (INGV) operates the Vesuvius Observatory, the world’s oldest volcano observatory, established in 1841. It monitors seismic activity, ground deformation, and gas emissions to detect signs of unrest. Naples has divided the region into risk zones, with detailed evacuation plans for the high-risk “red zone.” Public education campaigns and drills further enhance preparedness, ensuring that the lessons of Pompeii inform modern risk management.
Recent Volcanic Activity
Volcanic eruptions remain a present-day threat. In December 2021, Mount Semeru in Indonesia erupted, killing at least 23 people and covering villages in ash and mud. This event displaced thousands and highlighted the ongoing risks faced by communities near active volcanoes. Similarly, the 2018 eruption of Kilauea in Hawaii destroyed over 700 homes and forced evacuations, with lava flows reaching residential areas. These incidents underscore the importance of continuous monitoring and preparedness.
Cultural and Community Aspects
Living near volcanoes fosters a unique relationship between communities and their fiery neighbors. Volcanoes are often woven into local culture, folklore, and identity. In Japan, Mount Fuji is a sacred site and a symbol of national pride, attracting pilgrims and artists alike. In Hawaii, residents honor Pele, the goddess of volcanoes, through rituals and stories, reflecting a deep respect for the land’s power.
Residents of volcanic regions often exhibit remarkable resilience. For example, in Hawaii, despite the 2018 Kilauea eruption displacing many, communities returned to rebuild, drawn by cultural ties and economic opportunities. As one Hawaiian resident noted in a National Geographic article, “This is our home, and Pele is part of it. We respect her power and live with it.” Such sentiments reflect the balance of reverence and adaptation that defines life near volcanoes.
Conclusion
Living near volcanoes is a complex choice driven by economic, cultural, and practical factors. From the fertile fields of Catania to the geothermal springs of Kagoshima, these regions offer unique benefits that attract millions despite the risks. Historical events like the Vesuvius eruption of 79 CE and recent incidents like the 2021 Mount Semeru eruption remind us of the dangers, but modern monitoring and preparedness allow communities to thrive. By embracing both the rewards and challenges, these towns demonstrate humanity’s ability to coexist with nature’s most powerful forces.
