9 Volcanoes in News for UPSC Prelims 2026

Volcanoes are often in news due to eruptions, seismic activity, or new scientific studies. For UPSC Prelims, it is important to track such updates as they are directly linked to geography, environment, and disaster management. Below is a crisp list of nine volcanoes recently in news with their significance.

---

1. Campi Flegrei, Italy

• Why in news: AI-based seismic imaging revealed a hidden “ring fault” linked to earthquake swarms.
• Significance: A supervolcano near Naples with potential for catastrophic eruption; constant uplift and seismicity are monitored.
• Type: Caldera system.

---

2. Klyuchevskoy, Russia

• Why in news: Erupted after the July 2025 M8.8 earthquake in Kamchatka.
• Significance: Shows link between mega-earthquakes and volcanic eruptions.
• Type: Stratovolcano (Pacific Ring of Fire).

---

3. Kīlauea, USA (Hawai‘i)

• Why in news: Ongoing eruption since December 2024 with episodic lava fountains.
• Significance: One of the world’s most active and studied volcanoes; insights into eruption forecasting.
• Type: Shield volcano.

---

4. Wandan Mud Volcano, Taiwan

• Why in news: Eruption in 2025 with flames caused by ignition of escaping gases.
• Significance: Mud volcanoes indicate subsurface pressure and fluid systems.
• Type: Mud volcano (non-magmatic).

---

5. Mount Lewotobi Laki-laki, Indonesia

• Why in news: Erupted twice on 15 October 2025, sending ash up to 10 km high.
• Significance: Located in the Ring of Fire, such eruptions affect aviation and local communities.
• Type: Stratovolcano.

---

6. Krakatoa (Anak Krakatau), Indonesia

• Why in news: Ongoing minor strombolian eruptions.
• Significance: Historic 1883 eruption had global climate impact; today’s activity threatens tsunamis and aviation hazards.
• Type: Caldera and stratovolcano.

---

7. Krasheninnikov, Russia

• Why in news: Erupted in August 2025 after ~600 years of dormancy.
• Significance: Linked to regional megaquake; shows dormant volcanoes can reawaken suddenly.
• Type: Stratovolcano.

---

8. Uturuncu, Bolivia

• Why in news: Known as a “zombie volcano” showing uplift and seismic signals without eruptions.
• Significance: Demonstrates long-term magma accumulation and deformation.
• Type: Dormant stratovolcano.

---

9. Taftan, Iran

• Why in news: Thought extinct for 700,000 years, but now shows uplift and gas emissions.
• Significance: Reclassified as dormant; highlights importance of remote sensing for volcanic monitoring.
• Type: Stratovolcano.
