Caption:Here is a composite Landsat 8 image of Cleveland from the afternoon of 14 June 2015. The shortwave-IR data in color shows elevated temperatures in the summit and is overlain on the grayscale visible wavelength base. Note the light dusting of ash on the north flank as observed by C. Read on his commercial flight back to Anchorage. Snow-free ground near the summit is also evident, but not necessarily unusual.

Caption:Installation of joint MultiGAS/seismic station AUSS on summit of Augustine by Dane Ketner (USGS-AVO) and Peter Kelly (USGS-CVO), June 12 & 13, 2015. Image shows the completed installation with Dane Ketner and field gear staged in the background. Note the gas inlet on the side of the hut and the mound in the foreground which marks the location of the broadband seismometer. View is looking roughly WNW.

Caption:AVO/USGS geologist Kristi Wallace hand selects clasts from tephra fallout samples collected at Akutan, for x-ray fluorescence (XRF) and inductively coupled plasma mass spectrometry (ICP-MS). Geochemical data from these samples will help AVO to understand the composition of the magmas that generated eruptions over the last ~10,000 years at this volcano and will also help to link together eruptive products including lava, mudflow, and pyroclastic flow deposits of specific eruptions.
