The hottest place on Earth is not its inner core

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, since it is a relatively frequent phenomenon.

For a fraction of a second, the air surrounding a lightning bolt heats up to approximately 30,000ºC, the hottest temperature on Earth.

Another thing is that we look for places on the surface where the heat is very intense and very sustained. 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 terrestrial volcanoes.

They obtained data from heat flux readers taken between 2000 and 2014 by spectroradiometers on NASA’s Terra and Aqua satellites.

During that period, the Hawaiian Kīlauea volcano emitted 9.8 x 10 to the power of 16 J of thermal energy, enough to power New York City for six months.
