Poás Volcano, Active stratovolcano in Central Valley, Costa Rica.

The volcano features a massive crater measuring 1.6 kilometers across and containing a sulfuric acid lake with steam rising from multiple fumaroles.

The volcano has experienced 39 recorded eruptions since the mid-1800s, with a substantial event in 2017 leading to temporary closure and infrastructure modifications.

Local indigenous communities incorporate the natural formations of Poás Volcano into their traditional stories about earth spirits and natural forces.

Visitors must obtain advance reservations and can access the volcano between 7:00 AM and 2:00 PM, with guided tours limited to 20-minute intervals.

The crater contains Laguna Caliente, reaching depths of 900 meters and generating geysers that can shoot water up to 250 meters high.

Active volcanoes worldwide: online map

This collection brings together active volcanoes located on multiple continents, from Cotopaxi in the Ecuadorian Andes to Mount Fuji in Japan, including Vesuvius in Italy and Mauna Loa in Hawaii. Each site demonstrates different geological processes: stratovolcanoes like Mount Saint Helens and Etna produce explosive eruptions, while Hawaiian shield volcanoes generate flowing lava that can travel long distances. The selection also includes sites that have marked history through their destructive power, such as Krakatoa, whose 1883 eruption caused tens of thousands of casualties, or Vesuvius, which buried Pompeii and Herculaneum in AD 79. Other volcanoes like Iceland's Eyjafjallajökull have recently shown their ability to disrupt human activities globally. These locations offer insight into how volcanic activity shapes landscapes and influences nearby populations.
