  1. White Island volcano (NZ) has had a small, short-lived eruption last night; Alert level has been set to 3 (Eruption hazards near vent.). Just yesterday morning, Geonet had reported the dropping of the crater lake level of 2 meters in the last two weeks, but no other changes in volcanic behaviour hade been observed. http://info.geonet.org.nz/blog/volc

    • Volcanic alert level lowered to “2” (moderate to heightened volcanic unrest), with aviation color code still at orange. Webcam image from today showing the peculiar green ash after yesterday’s small eruption

    • At an aerial inspection yesterday GNS have found that a new crater has formed on White Island! They also said, it was likely the eruption was driven by steam and gas and there has been little to no lava emission. Below a view of the 1978/90 Crater Complex, the new crater and vent is right of centre. (Click for large img)

  2. An analysis of the deadly Kumamoto earthquakes (Beppu-Shimabara rift valley) shows the displacement due to right-lateral strike-slip fault: http://www.ajiko.co.jp/article/detail/ID56JI45Y2D/. It was found that the ground shifted horizontally by 10 centimeters or more over an east-west stretch of about 80 kilometers, and north-south for 40 kilometers; in places north of the Futagawa-Hinagu fault zone, the ground moved more than 1.5 meters eastward. It also sank more than 1.2 meters at points north of the fault zone. Ground on the south side rose more than 40 centimeters. (English interpretation from this newspaper: http://allexpatnews.com/quakes-shift-ground-80-km-east-west/)

  3. Since last Thursday, volcano Turrialba (Costa Rica) maintains a significant level of seismic activity characterized by continuous tremor and – over the last two days – numerous explosions emitting ash, steam and gases. Action is now to bring clean water to four communities located near the crater, who have been directly hit by the ash plumes. Their water sources have been affected. Also the National Park has been closed.

    Does anyone have a link to this webcam?
