Eruptions

Mixing volcanoes and oceans seem to always produce exciting results. Whether it is something as simple as the ocean entry of a lava to something as impressive as a new island emerging, formed by volcanic eruption. Back in the 1960s, a previous unknown undersea volcano off the coast of Iceland erupted to form the island…

The eruption of Hunga Tonga Hunga Ha’apai volcano in Tonga looks to be a big one. Keleti Mafi, head of the Tongan geological service, calls this “a very significant eruption, on quite a large scale”, which is no surprise considering some of the spectacular picture we saw of the eruption yesterday. In fact, the eruption…

New Eruption in Tonga

Image from keizo/weblog Hunga Tonga-Hunga Ha’apai (how’s that for a name?), a shallow seamount in Tonga, appears to have erupted. An air passenger snapped some pictures of an eruption occurring in the ocean between the Tongatapu and Vava’u and pilots in the area report that (unsurprisingly), the feature is new. Hunga Tonga-Hunga Ha’apai – at…

For those of you interested in what happens in the realm of submarine volcanism, I can pass on some tidbits I’ve gotten about NW-Rota 1, a submarine volcano in the Mariana Islands (see bathymetry above). Dr. Ed Kohut (Petrogenex), a friend of mine from my days at Oregon State Univ., is currently on a JAMSTEC research cruise…

The headline for this entry sounds more dramatic than it is, but one of the last structures in the ill-fated Royal Gardens subdivision on the big island of Hawai’i finally met its fiery demise over the weekend. For those of you unfamiliar with the plight of the subdivision, Royal Gardens is part of Kalapana, and…

Ash eruption video from Halemaumau

On Sunday afternoon, a large ash eruption occurred at Halemaumau Caldera at Kilauea. Not only did the volcano belch more grey ash than usual, but also red-hot incandescent material can be clearly seen being thrown from the vent during the vigorous eruption. The coolest thing about the eruption is that it was all caught on…

The big boulders of Tonga

This might not be directly related to a volcanic eruption, but it has been picked up by a lot of news sources, so I thought I’d give it a mention. A report from researchers at University of Texas hypothesize that some very large coral boulders (up to 10 meters tall) that can be found on…

Kilauea’s new fire fountain

  Kilauea is busy keeping geologists and tourists alike wondering what the volcano will be doing next. The current report on the volcano tells of a new fire fountain at the Thanksgiving Eve Break-out “rootless cone”, about 6 miles from the ocean. The fire fountain started on Sunday night, issuing lava up to 40 feet in…

Almost 9 months since its last eruption, Ruapehu is keeping New Zealanders guessing about its next move. Brad Scott of GNS Science (NZ) reports that the crater lake at Ruapehu is reading unusually warm temperatures and high gas emissions, well after geologists there would have expected after the last eruption. Their conclusion doesn’t seem to…

Not much in the way of science to add here, but photographers at Hawai’i Volcanoes National Park are still busy around the clock documenting the summit vent activity at Kilauea that started in March. Most of the activity is steam escaping from the vent, but at night, the vent glows red, proving just how close to the…
