Caption:Here is an image of Landsat-8 data of Cleveland collected on July 20, 2014 at 8:53 UTC. The shortwave-infrared (SWIR) data is in color, and shows elevated temperatures in the summit crater. The hottest pixel is about 300 degrees C. The SWIR data is overlain on thermal infrared data (in shades of grey: white is cold, black is hot), which shows low clouds obscuring the lower portion of the cone, and warm ground (black) around the crater. Note that the hottest region (shown in color) occupies a small portion of the summit crater.

Caption:Images from summit overflights of Cleveland Volcano on 4 and 15 August 2015. A) Thermal image from a Forward Looking Infrared (FLIR) camera and B) photo of the small lava dome growing in the summit crater. The hottest portion of the dome was the small central core at 550-600° C. The diameter of the crater rim is ~170 m. The extrusion of this dome was preceded by an explosion reported by David Fee on 21 July 2015 that likely destroyed the previous dome and allowed the final ascent and emplacement of the new dome. On 28 July, Rick Wessels reported that the small dome visible in the crater for the past several months had been destroyed and replaced with a ~40 m diameter crater. Michelle Coombs reported elevated surface temperatures in satellite checks beginning 29 July, probably indicating active effusion of the new dome visible in A) and B). Another explosion was reported by David Fee on 6 August, although weaker than the 21 July explosion. C) Thermal image and D) photo of the summit crater captured on 15 August. The outer diameter of the dome appears to be similar to the dome in the 4 August images, but the explosion appears to have removed some material from the center of the dome leaving two hot areas (possibly shallow craters) in the southwest and northeast sectors of the dome. Peak temperatures observed were ~100° C cooler than on 4 August, possibly due reduction or cessation of effusion and/or attenuation of the infrared energy by the thick steam. Steaming and fume obscured visual observations of the dome on 15 August.

Caption:Images taken during the 2015 field season of the upper portion of the Geyser Bight geothermal area on Umnak Island, Alaska. These images were captured during geochemical sampling by Cindy Werner and Christoph Kern that was funded by the Deep Carbon Observatory. A) Forward looking infrared (FLIR) image of the upper-most geothermal area showing intense fumarolic activity and boiling and near-boiling springs. B) Photo of the same area as in A). The yellow-clad figures are gas geochemists Cindy Werner and Christoph Kern of the Cascades Volcano Observatory sampling gases and waters from the geothermal features.

Caption:North Pacific and Russian Far East air routes (gray lines) pass over or near more than a hundred potentially active volcanoes (red triangles). Aircraft flying along these routes, some of the busiest in the world, carry more than 50,000 passengers and millions of dollars of cargo each day to and from Asia, North America, and Europe. In the North Pacific region, several explosive eruptions occur every year. Ash from these eruptions, which has caused jet engines to fail, is usually blown to the east and northeast, directly across the air routes.
