Landsat-8 data from 15 May 2015 at 22:17 UTC (2:17 PM AKDT) show robust steaming and high temperatures in Cleveland Volcano's summit crater (in the shortwave IR), indicating continued unrest. The high-temperature feature is visible in this image as a red pixel. Robust steaming observed extending to the west and seen as a shadow on the lower meterological cloud deck. Shortwave IR has very little reflectance from snow, which is why Cleveland appears blue.
