Incandescence is visible at night at Halema`uma`u crater at Kilauea summit. Small amounts of lava are being emitted from the vent, and ash emissions are visible during the day. On March 29 sulphur dioxide levels at the summit were 730 tonnes/day, compared to background levels of 150-200 tonnes/day. Sulphur dioxide emission rate increases from this level when ash emissions occur at the vent.

Karymsky Volcano, Kamchatka, Russia - John Seach
Eruptions have occurred at Karymsky Volcano in Kamchatka, Russia. More than 100 earthquakes were recorded in one day. Ash emissions have reached 7 km high and rockfalls were visible on the slopes. Ash emissions are creating an aviation risk.

Kilauea Volcano, Hawaii - John Seach
Eruptions continue at two locations at Kilauea volcano in Hawaii. Ash emissions are occurring from a 30 m wide vent at Halema`uma`u crater at Kilauea summit. Ashfall has deposited on Highway 11 and as far away as south point. Lava from Pu`u `O`o vent on the east rift zone is flowing through Royal Gardens subdivision and entering the sea at Waikupanaha and Ki ocean entries.

Kilauea Volcano, Hawaii - John Seach
Ash emissions are occurring from a small vent at Halema`uma`u crater, Kilauea volcano. This follows an explosion which occurred at the crater on the 19th March. The current explosive activity at the summit of Kilauea is the first in 84 years. Sulfur dioxide emissions are above background levels in the summit area. Crater Rim Drive remains closed between Kilauea Military Camp and Chain of Craters Road, due to high gas emissions and the possibility of further explosions. Lava continues to enter the sea at two locations (Waikupanaha and Ki) at Kilauea Volcano in Hawaii.

Mt Etna Volcano, Italy - John Seach
Weak explosive activity has been occurring since January at Mt Etna volcano in Italy. Ash emissions are occurring from a depression on SE Crater. Periods of activity were reported from 9-10 January, 11-17 February, 25th February-3rd March, and during the past 10 days. Significant activity at Mt Etna last occurred in April 2007 with lava fountaining, and lava flows.

Rabaul Volcano, Papua New Guinea - John Seach
Ash emissions continue from Turvurvur, Rabaul Volcano, Papua New Guinea. Moderate ashfall occurred at Matupit Island. Roaring noises were occasionally heard from the crater, and a night glow was visible.

Tibet Earthquake, 21st March 2008 - John Seach
A major earthquake, magnitude 7.2, hit Kunlun volcano region in Tibet this morning at 0633 hr local time. The epicentre was located 100 km east of Kunlun volcano, which produced China's most recent eruption in 1951. Earthquakes of this magnitude are able to disrupt nearby volcanoes. The Kunlun Fault system produced a magnitude 8.1 earthquake in November 2001.

Rabaul Volcano, Papua New Guinea - John Seach
A large eruption occurred at Turvurvur crater Rabaul Volcano, Papua New Guinea today at 11:05 hr local time. The shockwave rattled windows in Rabaul town and covered the cone with lava fragments. Ash emission reached 2.5 km above the crater.

Kilauea Volcano, Hawaii - John Seach
An explosive eruption occurred on 19th March, local time, at Halema`uma`u Crater at the summit of Kilauea Volcano in Hawaii. This is the first explosive eruption in the summit crater since 1924. The explosion occurred at the location of the new gas vent which formed last week. The eruption was probably phreatic, and created a crater 30 m in diameter. Debris was thrown as far as Crater Rim Drive near Halema`uma`u parking area. Crater Rim Drive has been closed recently due to high level of gas emission in the area.

Kilauea Volcano, Hawaii - John Seach
A new gas vent has opened in Halema`uma`u crater at the summit of Kilauea volcano in Hawaii. This is the first summit activity in 25 years at the volcano. The vent shows an orange glow at night, and has doubled the already high sulphur dioxide emissions at the summit. Along the east rift zone, lava has reached the sea at two locations - Waikupanaha, and a location 400 m east.

Garbuna Volcano, Papua New Guinea - John Seach
New eruptions began at Garbuna volcano in Papua New Guinea on 11th March 2008. Grey ash was emitted to an elevation of 1 km above the summit and ash fell SW of the volcano. Booming noises were occasionally heard at the volcano. This is the first activity at the volcano since 2005. Low levels of activity were recorded yesterday with white emissions from multiple locations on the summit.

Lava Destroys Three Houses in Hawaii - John Seach
Lava from Kilauea volcano in Hawaii has destroyed three houses in the Royal Gardens subdivision. The subdivision was mostly abandoned in the 1990's due to lava flows, and now only five houses remain. Channel-fed lava flows have formed within the subdivision. Lava flowing through vegetation is causing an explosion risk. Lava is pooling on the coastal flat.
