Kilauea Volcano, Hawaii - John Seach

Lava from Kilauea volcano has entered the Royal Gardens subdivision in Hawaii. On 29th January channelized 'a'a flow burned through vegetation and passed Tubarose St, Ali'i Avenue, and `Ekaha St. Lava has been flowing across old lava flows, and has covered some new areas. Lava flowing through vegetation can produce fire and methane explosions, and lava advancing over asphalt produces hazardous fumes and should be avoided.

Kelut Volcano, Indonesia - John Seach

A lava dome continues to grow at Kelut Volcano in Indonesia. A seismic crisis preceded dome formation in October 2007. The dome is growing and now measures 130 meters in diameter, with an area of 700,000 sq m. Recent lava dome formation, volcanic earthquakes, and gas emissions all indicate the volcano in on the verge of erupting. The larger the dome, the more powerful the eruption will be.

Indonesia Earthquake, 7th January 2008 - John Seach

A large earthquake hit West Papua, Indonesia today at 12:12 pm local time. Preliminary analysis by Geoscience Australia put the magnitude at 6.4. The epicentre was located 5 km off the coast near Manokwari, a town of 52,000 people. No tsunami was reported. The epicentre was 60 km north of Gunung Umsini. This mountain was previously thought to be a volcano, but there is no definite evidence of volcanic activity. West Papua is a seismically active region which lacks identified volcanoes despite its location between two volcanically active regions.

Kilauea Volcano, Hawaii - John Seach

This week marks the 25th anniversary of the current eruption at Kilauea Volcano in Hawaii. Its the longest lasting rift zone eruption at the volcano in 700 years. During the 19th and 20th century there was a 100 year long summit eruption which included a lava lake. Lava continues to erupt from the SE rift zone from fissures fed by shallow magma chamber under Pu`u `O`o crater. During the past 24 hours, lava advanced slowly southwards. Since July 2007, lava has been advancing in a NE direction outside the boundaries of Hawaii Volcanoes National Park.
