Earthquake & Volcano Monitor — 2026-05-27
Volcanic unrest is intensifying across multiple regions simultaneously, with Reventador producing massive ash output, Campi Flegrei showing increasing uplift, and Bezymianny releasing ash to 10,000 feet. Meanwhile, a magnitude 5.6 earthquake struck Indonesia's Maluku Sea on May 26, and Kīlauea's eruption remains paused at ADVISORY level following the end of its 46th lava fountain episode.
Earthquake & Volcano Monitor — 2026-05-27
Seismic Activity
Indonesia: M5.6 Maluku Sea (May 26, 2026) A strong magnitude 5.6 earthquake struck the Maluku Sea near Pulau Mayu island, North Maluku, Indonesia, at 5:39 am local time on Tuesday, May 26, 2026 (21:39 UTC on May 25). The quake occurred at approximately 40 km depth in the Maluku Sea.
Italy: Minor Vesuvio Tremor (May 26, 2026) A minor magnitude 0.6 earthquake was recorded at Vesuvio (Vesuvius) on Tuesday, May 26 at 12:51 am UTC. While the event is small, seismic activity at the famous volcano near Naples is routinely monitored.
The May 25 global earthquake report from VolcanoDiscovery documents seismic events worldwide throughout that reporting period.
Volcanic Watch
Reventador (Ecuador) — 1,200 Ash Columns Today's volcano news highlights an extraordinary level of activity at Reventador, with a reported 1,200 ash columns recorded. The volcano, located in the Ecuadorian Andes, has been among the most persistently active in the Western Hemisphere.
Campi Flegrei (Italy) — Seismic Swarm and Increasing Uplift The same May 26 update reports a small seismic swarm and increasing uplift at Campi Flegrei. Additionally, 26.6 cubic metres of new magma has been measured beneath Svartsengi. Campi Flegrei remains under close scientific scrutiny due to its supervolcano potential and proximity to the city of Naples.
Bezymianny (Kamchatka, Russia) — Ash to 10,000 ft A Volcanic Ash Advisory was issued for Bezymianny on May 25, 2026, at 04:30 UTC, reporting volcanic ash extending to FL100 (approximately 10,000 feet / 3,000 m) moving southward. Satellite imagery from May 25 documented the event.
Kīlauea (Hawai'i, USA) — Eruption Paused, Advisory Level The USGS Hawaiian Volcano Observatory reports that the Halemaʻumaʻu eruption of Kīlauea is currently paused, with the aviation color code at YELLOW and the alert level at ADVISORY. Lava fountain Episode 46 ended on May 6, 2026. Scientists continue to monitor conditions for a potential resumption of eruptive activity.
Stromboli (Italy) — Goat-Related Hazard Incident In an unusual report, today's volcano news from Volcano Earth includes a story about "troublesome goats" at Stromboli — highlighting the variety of challenges that arise around active volcanic areas.
Alaska — Small Earthquakes, YELLOW Advisory The Alaska Volcano Observatory reports a few small earthquakes detected by regional seismic stations over the past day at an instrumented Alaskan volcano (elevation 9,373 ft / 2,857 m, coordinates 56.0126°N, 159.7912°W), currently at YELLOW/ADVISORY status as of May 25, 2026. Cloud cover obscured satellite imagery.
Earth Science
Weekly Volcanic Activity: 27 Volcanoes Active The Smithsonian/USGS Weekly Volcanic Activity Report for the week ending May 20, 2026 documented activity at 27 volcanoes globally. New activity or unrest was reported for 7 volcanoes during May 14–20, while ongoing activity continued at 20 additional volcanoes.
Campi Flegrei Uplift Context Monitoring data showing increasing uplift at Campi Flegrei is scientifically significant. The caldera system west of Naples has been experiencing bradyseism — ground deformation driven by subsurface magmatic and hydrothermal activity — for decades. The detection of both a seismic swarm and accelerating uplift in the same reporting window warrants continued close observation by researchers at Italy's INGV.
