While heat flow through Earth's crust has been measured at at least 34,000 different spots around the globe, in Antarctica it has been measured in less than a dozen places. In July 2015, scientists reported the heat flow at one of these spots was four times higher than the global average...
The algorithm represents a volcano-devoted enhancement adopting, as a starting point and solid reference, the HOTMAP detection method [43]. But it fully differs, since here the algorithm is developed applying spatial and statistical criteria, reaching an improved care to detect hot pixels on volca...
