Here are Landsat-8 data from Karangetang (Api Siau) volcano from April 28 and May 2, 2015. The data from April 28, 2015 is local daytime so there is visible wavelength data, but it is cloudy on the summit so the volcanic activity is seen clearer in the infrared data.
The May 2, 2015 data is local night time, so it is seen in Bands 975 as well as in Band 10. The activity, which has been determined by others as a possible lava flow, is around 1.57 km or 1 mile long.
