Islands around the world are often named after their most striking natural features. Some gain special titles because of dramatic landscapes formed by nature over thousands of years. Powerful volcanic forces, flowing lava, glowing mountains, and frequent eruptions have shaped one such island’s land and history. These fiery elements have influenced local life, traditions, and even farming, giving the island a strong and memorable identity.
Which Island is known as the Island of Fire?
Siquijor Island, located in the Philippines, is famously known as the Island of Fire. It is a small island province in the Central Visayas region, lying in the Bohol Sea, south of Cebu and near Negros Oriental. Despite its small size, Siquijor has gained worldwide attention because of its unusual name and rich cultural traditions.
Why is Siquijor called the Island of Fire?
Siquijor earned the name “Isla del Fuego”, which means Island of Fire in Spanish, during the 16th century. When Spanish explorers first approached the island at night, they saw what looked like glowing flames along the coastline.
This glow was not caused by fire or volcanoes. Instead, it came from thousands of fireflies resting on molave and mangrove trees. Their combined light made the island shine brightly in the dark, creating the illusion that the land was on fire. This magical sight was clearly visible from ships at sea, leaving a strong impression on early visitors.
Historical Background of the Name
Spanish explorers and early chroniclers officially recorded the island as Isla del Fuego. The glowing fireflies were considered a natural wonder and became a defining feature of the island’s identity. Over time, the name remained, even as modern explanations clarified the true cause behind the glow.
Natural Features of Siquijor Island
Siquijor is not only famous for its name but also for its natural beauty. The island is mostly made of coralline limestone, formed from ancient coral reefs that hardened over thousands of years. This shows that Siquijor was once underwater.
The island is surrounded by clear blue waters, coral reefs, seagrass beds, and mangrove forests. These ecosystems support rich marine life and are part of the Coral Triangle, one of the most biodiverse ocean regions in the world.
Culture, Traditions and Beliefs
Siquijor is well known for its mix of Catholic traditions and ancient folk practices. Many locals still practise herbal healing and spiritual rituals passed down through generations. Because of this, the island is often associated with mysticism and traditional medicine, which adds to its mysterious charm.
Lesser-Known Facts About Siquijor
- Siquijor is the third smallest province in the Philippines in terms of land area and population.
- Before Spanish rule, it was called Katugasan, named after the molave trees that once covered the island.
- Fossils of giant clams are sometimes found inland, far from the sea.
- A famous balete tree with a natural spring at its roots is believed by locals to have healing powers.
- Fireflies, which gave the island its name, are also a sign of a clean and healthy environment.
Is the Island of Fire Volcanic?
No, Siquijor is not a volcanic island. The word “fire” in its name refers only to the glow of fireflies, not lava or eruptions. This is an important distinction, as some other islands are known for real volcanic activity.
Island Born of Fire
Another Philippine island, Camiguin, is known as the Island Born of Fire. Unlike Siquijor, Camiguin has several volcanoes, including Mount Hibok-Hibok, which has erupted in the past and shaped the island’s landscape.
Land of Ice and Fire
On a global level, Iceland is called the Land of Fire and Ice. This name comes from its powerful volcanoes and lava fields combined with massive glaciers and ice caps, showing a dramatic contrast between heat and cold.
