Francisco Negroni is a Chilean freelance photographer has spent years pointing his camera at volcanic eruptions. Over time, he has captured a series of incredible photos showing the lightning of "dirty thunderstorms" that are found in massive volcanic plumes.
Back in 2010, a series of volcanic eruptions in Iceland captured the world's attention. Although they were relatively small in scale, the ash that was spewed into the air disrupted air travel across Europe for a number of days. Photographer Sigurdur Stefnisson witnessed the eruptions first hand, and was able to capture a series of jaw-dropping photographs showing the power and scale of the ash clouds, lightning, and lava.
In September and October of 1994, the space shuttle Endeavour was orbiting 115 nautical miles above Earth while the Kliuchevskoi Volcano was spewing ash and dust into the atmosphere at an alarming rate. Not in any position to do anything about it, the astronauts aboard the space shuttle did the only thing they could do... they took pictures.
