Did I mention its a busy week? The lava lake at Erta’Ale in 2008. Image courtesy of Stromboli Online. Our Icelandic saga continues, with more earthquakes and more speculation/information on the parts of Eruptions readers. Keep up the discussion – I’ll be fascinated to see who turns out to get closest to what actually happens,…

Monday Musings

New lava lake sighted at Kilauea

Not sure how it was kept quiet for most of the week (well, at least to me), but geologists at the HVO have noticed a new lava lake in Halemaumau Caldera on Kilauea (Hawai’i). The lava lake is around 330 feet (~100 meters) below the crater rim and ~160 feet (50 meters) across with sections…
