Chile’s Puyehue volcano erupted on
Sunday June 5, 2011, after a series of earthquakes, and later put on an
unbelievable show – captured in this image – that no man could have
watched in the flesh. It took a minutes-long exposure to create the
photograph. This long exposure allowed the individual bolts of lightning
to appear all at once in the image, while the rotation of the Earth
makes the stars on the left appear as streaks.
In this next image, a plume of boiling
hot ash is lit by lightning. National Geographic’s Daily News gallery
put the series of images together, and their volcanic seismologist Steve
McNutt explained that there could be three types of volcanic lightning:
„Large, spectacular „natural fireworks“ sometimes accompany eruptions,
along with an intermediate type, which shoots up from a volcano’s vents
and reaches lengths of about 1.8 miles (3 kilometers), and finally bolts
that can be as short as about three feet (one meter) long and last just
a few milliseconds.“
Lightning and thunder are two of mother
nature’s least understood weather phenomena since they can’t easily be
recorded, as a hurricane can be with aircraft. Volcanic lightning is
even less understood but is one of nature’s most spectacular sights.
Thanks to the work of talented photographers, we get to see it from the
safety of our armchairs.
