There is a place on our planet that is about five times hotter than the visible surface of the Sun or the inner core of the Earth.
It is something that does not last long but that everyone has seen, because it is a relatively frequent phenomenon .
For a fraction of a second, the air around a lightning bolt heats up to about 30,000 ° C , the highest temperature on Earth.
Another thing is that we look for places on the surface where the heat is very intense and in a very sustained way. So, we have to look at the volcanic heat emission .
On January 28, 2015, Geophysical Research Letters published an article analyzing 95 of the most active volcanoes on Earth.
They obtained data from heat flux readers taken between 2000 and 2014 by spectroradiometers on NASA’s Terra and Aqua satellites.
During this period, the Hawaiian Kīlauea volcano emitted 9.8 x 10 to the power of 16 J of thermal energy , which would be enough to supply electricity to New York City for six months.
