Somebody did NOT realize that this was a leap year, apparently. So maybe it will be up by tomorrow in case St. Helens burps.

    This looks like Hawaii, but it's not (currently the Kilauea eruption does not have active ocean entries). This is the ocean entry of the lava flow from Piton de la Fournaise volcano on the island of La Reunion in the Indian Ocean (featured a couple of weeks ago because it also has spectacular waterfalls). So right now it has both spectactular waterfalls and lavafalls. Click the linked source above for a page with several additional javascripted images of the eruption. Two of them are aerial photographs apparently showing the lava flow crossing the ring road around the island.

    I haven't posted Kilauea volcano pictures for a little while, but the eruption just keeps on going and going. It had been sending lava onto the coastal flats, so there hadn't been any recent ocean entries, but a fairly large flow called the 'Banana' flow reached the ocean yesterday. I've posted two nice pictures, but for fans of molten lava, there are a lot of new ones on the linked site above.

Here's a picture of what it looked like in 2002. (It's also spelled Nyamulagira.) Here's the report from May 8: Goma Volcano Observatory is announcing the beginning of a new eruption of Nyamulagira. Strong volcanic tremor signalled the onset of eruptive activity on May 8. Activity seems to have begun in the summital caldera of Nyamulagira and later propagated on the North flank. This volcano had shown several seismic swarms...

    Science - Reuters ^ | 2004-04-23
    WASHINGTON (Reuters) - Tiny, bacteria-like organisms made their home in hardened lava some 3.5 billion years ago, scientists reported on Friday in a finding that pushes the limits of when life is known to have started on Earth. The microbes, known as archaea, dug into volcanic rock to form long tubes. A team from the United States, Norway, Canada, and South Africa found evidence of the lava-burrowing archaea in 3.5 billion-year-old rock in South Africa. "Our evidence is among the oldest evidence for life found so far," said Hubert Staudigel, a research geophysicist at the Scripps Institution of Oceanography at...

    ELLOWSTONE NATIONAL PARK, Wyo. — The rolling pine forests, snowcapped mountains and crisp fall evenings here tend to make people forget the fact that the park sits atop a huge simmering underground volcano. But new geologic events have served up reminders.In a few days in July, acidic ground water dissolved parts of the unpaved trails in the Norris Geyser Basin, and the ground temperature of the trails shot up to 200 degrees from the usual maximum of 80. Park officials closed nearly half of the basin's trails, and they remain shut. On Aug. 21, a magnitude 4.4 earthquake shook the...

    Mauna Loa Could be Headed for Eruption MAUNA LOA, Hawaii, October 15, 2002 (ENS) - Mauna Loa, Hawaii's biggest volcano, is showing signs of life again almost two decades after its last eruption. Recent geophysical data collected on the surface of the 13,500 foot volcano revealed that Mauna Loa's summit caldera has begun to swell and stretch at a rate of two to 2.5 inches a year, say scientists from the U.S. Geological Survey (USGS) and Stanford University. Surface inflation can be a precursor of a volcanic eruption, the scientists warn. "Inflation means that magma is accumulating below the...

    PARADISE RIDGE, Mount Rainier — They were a scientific odd couple, a perfect pair to make a breakthrough discovery. Geologist Dave Lescinsky knew glaciers, and his sure-footed mountain-climbing friend Tom Sisson had seen more of Rainier's oddities than most scientists. For years, it was assumed Mount Rainier's 25 mightiest glaciers chewed Washington's tallest volcano into its irresistibly craggy form. As lava spewed from Rainier's gullet over the eons, the theory went, fiery molten rock gushed from the summit, filling the valleys. Then the rivers went to work, sluicing out new valleys, ultimately exposing Rainier's signature ridgelines. Lescinsky and Sisson weren't...
