Caption:Janet Schaefer (AVO/DGGS) describes Makushin's past eruptions to Harold Montgomery of the Ounalashka Corporation, and discusses impacts to Unalaska / Dutch Harbor if Makushin produces similar-sized eruptions in the future. This outcrop is located near the top of Haystack Hill.

Caption:Landsat-8 satellite image of Cleveland Volcano, draped over topography, collected on the night of July 23, 2015 at 08:53 UTC (12:53 am AKDT). The grayscale base image is from thermal infrared (TIR) data, and shows temperatures from cool in white to warm in black. The color overlay is short-wave infrared data, and shows high temperature features that aren't seen in TIR data. A hot summit vent is observed (as a red dot), surrounded by slightly cooler (but still hot) deposits likely from the explosion on 21 July. Note that steaming or clouds obscured a portion of the hot deposits on the south side, observed as an indent in the (likely) circular deposit.

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.
