WebLava tubes are very efficient transporters of lava from the vent to the flow front, and Laszlo Keszthelyi has recently calculated that lava flowing in a tube loses only about 1ºC of heat/kilometer. At the flow front, the lava behaves much like a river delta, forming small distributary tubes that continue to branch until they consist of the ... WebScientists don’t fully understand how and why hotspots occur, and there is vigorous scientific debate about their origins.
