Krakatoa volcano stirs to life again

The volcanic island of Krakatau (previously called Krakatoa) is situated in the Sunda Strait between the islands of Java and Sumatra in the Indonesian province of Lampung. The name is also used for the surrounding island group comprising the remnants of a much larger island of three volcanic peaks which was obliterated in a cataclysmic 1883 eruption. In 1927, a new island, Anak Krakatau, or “Child of Krakatoa”, emerged from…

Iceland’s monster volcano charging up for eruption

The Katla volcano, hidden beneath the ice cap of Mýrdalsjökull glacier in Iceland, has historically erupted violently once every 40-80 years.  In-as-much as it’s last such eruption took place one hundred years ago, in 1918, Katla’s next eruption is long overdue. An eruption in Katla would dwarf the 2010 Eyjafjallajökull eruption, scientists have warned. A…

Has a new volcano formed in Hawaii?

Story by David Rothery Professor of Planetary Geosciences, The Open University Kilauea, the most active volcano on Hawaii, has been in continual eruption since 1983. It entered a new phase in early May when fractures along a rift on the eastern side of the volcano opened during a series of earthquakes – some of which became volcanic fissures…

Stacking Up Volcanoes

  Guest Post by Willis Eschenbach [See Update at end] As readers of my posts know, I’ve held for many years that there are a variety of emergent phenomena that regulate the earth’s temperature. See my posts The Thermostat Hypothesis and Emergent Climate Phenomena for an overview of my hypothesis. One of the predictions derivable…

The month-long Kilauea eruption as seen from orbit

In early May 2018, an eruption on Hawaii’s Kilauea volcano began to unfold. Here’s what satellites saw in the first few weeks of the eruption. This video is a compendium of satellite views from NASA and other sources that tell the story of the eruption over the last month. For more details about these images,…

When Eruptions Don’t

Guest Post by Willis Eschenbach Inspired by Richard Keen’s interesting WUWT post on using eclipses to determine the clarity of the atmosphere, I went to the website of the Hawaiian Mauna Loa Observatory. They have some very fascinating datasets. One of them is a measurement of direct solar radiation, minute by minute, since about 1980. I…
