What are the red dots on the image Mike ?

A quick follow up. This is in their FAQ:

"The red boxes indicate the location of a thermal anomaly that was detected
by MODIS using data from the middle infrared and thermal infrared bands. In
most cases, this thermal anomaly is a fire, but sometimes it is a volcanic
eruption, or even the flare from a gas well. We have no way of knowing
which it is based on the MODIS data alone. In areas of known volcanic
activity, we can verify an eruption using published reports of volcanic
activity worldwide. The red outlines don't represent the actual size of the
fire. They indicate the perimeter of 1km-resolution pixels containing the
thermal anomaly detected by MODIS."
