Detailed Description

Composite false-color Landsat-8 satellite image of Semisopochnoi Island on July 14, 2014, produced by combining the shortwave infrared, near infrared, and visible wavelength data. This color combination enhances the visualization of vegetation, exposed rocks, and snow (light blue). This is a rare, partly cloudy satellite image and some of the volcanic features are indicated. The image does not show evidence of increased surface temperatures in response to the increased number of volcanic earthquakes that began in early June 2014.
