Earthquake & Volcano Monitor — June 12, 2026
A magnitude 4.7 earthquake struck near Hawaii on June 9 with no impact on local volcanoes, while Ecuador's Sangay volcano continues ash emissions to 21,000 feet. Researchers have developed a novel method to detect silent volcanic gas buildup months before eruptions, potentially improving early warning systems worldwide.

Seismic Activity
Hawaii Earthquake — No Volcanic Impact
On June 9, 2026, a magnitude 4.7 earthquake occurred 14 miles (23 km) east of Pāpa'ikou on the Island of Hawaiʻi at a depth of 24 miles (39 km) below sea level. The U.S. Geological Survey confirmed the earthquake had no apparent impact on either Mauna Loa or Kīlauea volcanoes.
Volcanic Watch
Sangay Volcano (Ecuador) — Ongoing Ash Advisory
Ecuador's Sangay volcano continues to produce volcanic ash clouds. The Volcanic Ash Advisory Center reported ash emissions reaching 21,000 feet (6,400 meters).
Active Volcanic Monitoring in Ecuador
Monitoring data from June 10 indicated increased fluid dynamics seismicity at Nevado del Ruiz volcano, while Fuego volcano in Guatemala recorded explosions and incandescent avalanches.

Breakthrough: Detecting Silent Gas Buildup Before Eruptions
Researchers at Geosciences Barcelona (GEO3BCN-CSIC) have developed a novel technique to monitor the silent accumulation of volcanic gases beneath Earth's surface using seismic ambient noise. The method successfully tracked gas buildup six months before the La Palma eruption, representing a significant advance in volcanic monitoring capabilities.
"The results could significantly improve early warning systems for volcanic eruptions," according to the research team's findings. This non-invasive approach could help scientists predict dangerous eruptions months in advance, potentially saving lives and enabling better preparedness measures.
