Mount Unzen

Located on Kyushu Island in Japan, Mount Unzen is one of the oldest known active volcanoes, having formed approximately 2.5 million years ago. This volcano has a long history of eruptions, with significant activity recorded in the early 1990s. Notably, Mount Unzen is infamous for its dangerous pyroclastic flows. Historically, the local population utilized its sulfur for various applications, including gunpowder production. A museum in the area now commemorates the workers impacted by sulfur mining.

Mount Pinatubo

In the Philippines, Mount Pinatubo has been active for over a million years. Although it remained dormant for several decades, it gained international attention following its massive eruption in 1991, which had significant environmental and climatic repercussions globally. The volcano is surrounded by lush forests and deep valleys, presenting both beauty and a reminder of its power. Even post-eruption, the area indicates ongoing subterranean activity, keeping scientists alert to the potential for future eruptions.

Taal Volcano

Situated in Batangas on Luzon Island, Taal Volcano is celebrated as one of the Philippines' most active and oldest volcanoes. Its long history of eruptions spans thousands of years, with the latest major event occurring in 2020. What distinguishes Taal is its unique geographical configuration—an island volcano located within a lake, which in turn is situated within a larger volcanic caldera. This distinctive feature draws the attention of both scientists and tourists alike. Despite its picturesque allure, Taal poses a high-risk factor due to its unpredictable and powerful eruption history.
