Seismic Activity
Philippines M7.8 Sarangani Earthquake
On June 7, 2026, a magnitude 7.8 earthquake struck near Sarangani in the Philippines, triggering tsunami warnings and numerous aftershocks. The event raised concerns about volcanic risks across Mindanao, with multiple volcanoes in the region now under elevated monitoring. The earthquake was felt widely and generated significant felt reports across the affected region.
Global Earthquake Report for June 10
The World Earthquake Report for Wednesday, June 10, 2026, documented continued seismic activity worldwide. Recent earthquake activity included a magnitude 6.1 earthquake near Mantua, Cuba, on June 8, 2026, at 18:00 UTC, with a depth of 26 km and reported felt by over 5,000 people.
Volcanic Watch
Sangay Volcano, Ecuador
Sangay volcano in Ecuador remains actively eruptive with volcanic ash reaching 21,000 feet (6,400 m) above mean sea level, according to Volcanic Ash Advisory Center alerts issued June 9–10, 2026. The volcano continues to produce significant ash emissions affecting downwind areas.
Reventador Volcano, Ecuador
Reventador volcano in Ecuador is also actively erupting, with volcanic ash observed in webcam imagery and reported in Volcanic Ash Advisory notices. The volcano continues to be monitored for ash dispersal patterns.
Mayon Volcano, Philippines
Mayon volcano in the Philippines exhibited eruption activity on June 9, 2026, at 19:06 UTC, with volcanic ash extending to flight level 090 (approximately 9,000 feet) to the northwest. The Volcanic Ash Advisory Center Tokyo issued alerts tracking the ash plume.
Campi Flegrei, Italy
Fumarole temperatures at Campi Flegrei near Naples, Italy, continue to increase, signaling elevated thermal activity at the caldera complex. This ongoing trend underscores the importance of continued monitoring at this high-risk volcanic system.
Earth Science
Volcanic-Seismic Linkages in Mindanao
The June 7 Philippine earthquake has raised awareness of the interconnection between seismic activity and volcanic hazard potential in subduction zones. Mindanao's active volcanic arc, including Mayon and nearby volcanoes, sits along a region of high seismic stress. Enhanced monitoring of both seismic activity and volcanic degassing is critical for public safety in this densely populated region.
Kupreanof Volcano, Alaska – Ongoing Seismic Activity
Kupreanof volcano in Alaska remains at ADVISORY alert level (Yellow aviation color code) as of June 10, 2026, with occasional earthquake activity continuing. This demonstrates the importance of sustained volcano monitoring networks in remote regions.
