Tarawera
eklemetti | August 9, 2010Quiet weekend on the whole, volcano-wise, beyond the articles about the latest eruption at Karangetang. So, we'll start this week with a new Mystery Volcano Photo. The last MVP was Tarawera in a shot I took from a road on the back side of the volcano, so that leaves the current standings looking like this:

One of the more impressive areas I visited while in New Zealand was the Waimangu Valley near Mt. Tarawera (above). The valley itself was created by blast explosions (phreatic explosions) during the 1886 eruption of Mt. Tarawera. These eruptions cut right down the axis of the rhyolite domes (most of which erupted ~1305 A.D.) and extended off the volcanic edifice to form the valley to the west of the volcano. In the valley, no juvenile lava was erupted, instead explosions carved out large pits that formed the Waimangu Valley and today the valley is filled with lakes and thermal features (below…

Right as Yellowstone is getting interesting (or at least had signs of interest), Eruptions is going on a bit of a break again starting January 2. This time it is because I'm off to the North Island of New Zealand to do some field work. I'll be headed to Tarawera (hopefully both the 1305 and 1886 eruption deposits), Taupo, Tongariro, the area around Rotorua and maybe even White Island (amongst other). I won't have my MacBook, but I will have my iPod Touch, so I'll try to keep track and make brief posts if something big comes up, but feel free to use this post as a clearinghouse for any news…

I mention this little human interest piece mostly because I am especially found of Mt. Tarawera (note: this link goes to the GVP page for Okataina, the volcanic cluster of which Tarawera is a member)Â in New Zealand. This Tuesday (June 10) is the 122nd anniversary of its most recent eruption, the 1886 eruption that erupted the Rotomahana Basalt. The eruption itself was relatively unique as it was a basaltic eruption that was almost entirely dominated by explosive eruptions of basaltic tephra (see illustration above). This likely means that the basalt was highly enriched in volatiles gases…
