Mount Dempo in South Sumatra, Indonesia, erupted at 04:45 UTC on April 15, 2026, sending volcanic ash as high as 7.6 km (25 000 feet) above sea level and prompting Indonesia’s volcano agency to raise the Aviation Color Code to Red. The eruption follows a phreatic blast on April 7 and inflation detected from April 2.
Tephra up to 25 cm (10 inches) was reported in the Volcano Golf Course subdivision near Kīlauea, Hawaiʻi, during episode 44 of the ongoing summit eruption, which ended at 05:41 UTC on April 10, 2026, after 8 hours and 31 minutes of lava fountaining. The eruption generated 5.8 million m³ (7.5 million cubic yards) of lava, while ash and Pele’s hair reached as far as Hilo, prompting warnings and temporary closures.
Explosive activity at Sheveluch volcano, Kamchatka, Russia, sent volcanic ash to 11 km (36 000 feet) above sea level on March 29, 2026, prompting authorities to raise the Aviation Color Code to Red.
An explosive eruption occurred at Semeru volcano in East Java, Indonesia, at 08:49 LT (01:49 UTC) on March 29, 2026, producing an ash plume rising 800 m (2 625 feet) above the summit and a pyroclastic density current traveling 3.5 km (2.2 miles) toward the Besuk Kobokan drainage.
A new volcanic eruption occurred at Whakaari/White Island, New Zealand, at 17:35 LT on March 24, 2026, producing a dark grey ash plume rising to about 1 300 m (4 265 feet) above the vent. Authorities raised the Volcanic Alert Level to 3 and the Aviation Color Code to Orange following the event. Activity has since ceased, but further explosive events remain possible with little or no warning.
Explosive activity at Sheveluch volcano on the Kamchatka Peninsula, Russia, produced a volcanic ash plume rising to approximately 10.4 km (34 000 feet) altitude at 11:20 UTC on March 16, 2026, drifting east across the North Pacific. Satellite imagery from Himawari-9 detected the ash cloud moving east at around 110 km/h (70 mph). The Aviation Color Code remains at Orange.
Lava from an ongoing eruption at Piton de la Fournaise entered the Indian Ocean along the southeastern coast of Réunion Island at about 00:20 local time on March 16, 2026, after advancing downslope through the Grand Brûlé lava field and crossing the RN2 coastal road several days earlier, producing steam plumes and localized hazards where molten rock met seawater.
An explosive eruption occurred at Kanlaon volcano on Negros Island, central Philippines, at 18:07 LT (10:07 UTC) on March 15, 2026, producing an ash plume rising more than 5 km (3.1 miles) above the summit and depositing ashfall across at least 54 barangays in 11 local government units. Monitoring data associated with the event recorded nine volcanic earthquakes and sulfur-dioxide emissions of about 1 085 tonnes per day. Authorities also reported vegetation fires on the volcano’s slopes and suspended classes in several municipalities on March 16 as a precaution.
Lava from an ongoing eruption at Piton de la Fournaise crossed the RN2 coastal road in the Grand Brûlé sector of Réunion Island early March 13, 2026, cutting a key transport link between the island’s southern and eastern regions.
A weak eruption was detected at Whakaari / White Island volcano in the Bay of Plenty, New Zealand, on the morning of March 12, 2026, prompting authorities to raise the Volcanic Alert Level from 2 to 3 and the Aviation Colour Code from Yellow to Orange. According to GeoNet monitoring data, ash was observed in a low-level plume above the main vent, with ashfall confined to the crater floor.
