A brand new Eruption Update is now available for Spring 2014. Come see the latest activity on our favorite volcano, Kilauea.
An exciting few days for New Zealand geologists. Over 48 hours, two volcanoes in New Zealand have had minor eruptions. Early on Sunday morning (04.55 NZST on 5 August), White Island had a small explosive eruption. The eruption was captured on one of the webcams located in the crater area. White Island is New Zealand’s most active volcano, having been in frequent eruption between 1976 and 2000, though recently quiet.
The volcanic alert level was raised to 2 and aviation colour code to orange.
Less than 48 hours later, Tongariro had a phreatic eruption at 23.50 on 6 August, its first eruption in 115 years. The eruption lasted a couple of minutes and light ashfall was deposited to the north east of the volcano, closing roads and cancelling domestic flights. This followed an increase in seismic activity over the previous 3 weeks.
The volcanic alert level was raised to 2 and aviation colour code to red, although the latter was reduced to orange after 12 hours as activity seems to have subsided. Here’s a link to the hazard map of Tongariro.

Had an exciting trip to check out the flow field Tuesday, with Adam G. as my intrepid assistant. We had a quick flight to get some aerial reconnaissance photos and figure out what the lava was up to. We were dropped on what I believe was Orchid Street in the small eastern kipuka of Royal Gardens subdivision. Lava was up above us, beginning to cross Paradise, and making its way towards an abandoned house in the forest. We spent some time hiking up and down the steep hillside filming the creeping lava flows and burning vegetation. Saw and heard lots of methane explosions. Fires kept whipping up in the wind and it seemed that the house might burn before lava got close. We crossed to the other side of the kipuka to see lava coming down Paradise road. It had just about reached the west side already and as we watched, began moving down the west side of the kipuka. We had to stand downwind of the burning asphalt, which is pretty horrible stuff. Good thing the gas masks worked perfectly, no problems. It’s just that we ended up covered in sticky soot. But it was worth it to watch the lava.
The hike down the pali and back out to the truck was tough and the rain finally hit, but all together a great day.
The new Winter 2012 Eruption Update is now available. This version includes some of the spectacular footage of lava rivers and falls that I got a few months back (and more), as well as almost 30 years of activity. The blu-ray disc contains a whole extra program called “Songs of the Molten Earth.” I’m particularly fond of that one. Check it out on our website!
