Lava is beginning to return to the summit of Kilauea volcano in Hawaii. Seismic tremor and summit earthquakes have been accompanied by a glow at the vent in Halema`uma`u crater. Lava remains deep inside the vent but increased glow followed earthquake activity below south caldera. Sulphur dioxide emission rates at the summit remain elevated. Lava [...]
Seismic activity at Chaiten volcano in Chile remains high, with earthquakes reaching a maximum magnitude 4.5. Dome growth continues in the summit crater. Ash emissions rose to a height of 1.5 km above the crater. During the week of 15-21 April, there were only two days where the summit was cloud free. The volcano remains [...]
Slamet volcano in Indonesia has begun erupting this week. The number of explosion earthquakes detected were 49 on 19th April, 97 on 20th April, 163 on 22nd April, and 52 yesterday. Emissions were visible rising 800 m above the summit. Slamet volcano was raised to level 3 alert (Siaga), and the summit has been closed [...]

A magnitude 5.0 earthquake hit the south flank of Kilauea volcano on 14th April at 12:44 pm local time. The epicentre was 14 km south of the town of volcano, near Hilina Pali. Kilauea summit recorded weak deflation after the earthquake. In the past 25 years there have been 3 earthquakes over magnitude 5 in [...]
Seismic activity has increased at Chaiten volcano since 8th April 2009. The trend increased further from 11-12 April with earthquakes up to magnitude 4.5 recorded. The increased number of earthquakes is associated with growth of the summit lava dome. Dome collapse remains a hazard, and may generate ash and block flows which can affect the [...]
A new eruption began at Fernandina volcano on 10th April 2009 at 2200 hr. The seismic station at Puerto Ayora did not record any earthquakes associated with the eruption. The eruption was observed by rangers from Galapagos National Park, and a tourist boat in the early hours of Saturday morning (local time). An eruption column [...]
