results or just more stronger eruptions to come?
Since I posted this on Aug 2nd -came to find out the
Iceland volcano is still spewing-found this tonight,
Aug 3rd, in my news feed
Newly Erupting Volcano Is Whipping Up Tornadoes as Lava
Explodes
Story by Jess Thomson •

A volcano in Iceland that recently began erupting,
spewing lava amid explosions from its depths, has also
caused another strange natural phenomenon to occur—
tornadoes.
A video posted to YouTube by drone photographer Martin
Sanchez on July 24 shows the tornado spinning violently
right next to a flow of explosive lava from the
volcano.
"I have never seen this before in my life. I did
capture the previous volcano eruptions here in Iceland
but as a power drone pilot this was my first time
flying a drone next to a Tornado and Volcano at the
same time!" Sanchez told Newsweek.
The volcano, named Litli-Hrútur—translating to Little
Ram—began erupting on July 10. It's actually part of a
larger volcano, named Fagradalsfjall, which also
erupted last summer, and the one before that, after an
800-year hiatus from activity.
As the Litli-Hrútur site began to erupt, lava and toxic
gases including sulfur dioxide spilled out from a large
fissure measuring about 2,600 feet. Since the eruption
has eased, the fissure has shrunk to about 250 feet
long, according to the NASA Earth Observatory.
The tornado likely formed as a result of the hot lava
spewing from the fissure, heating the air directly
above it, causing the air to rise and spin upwards in a
spiral.
"This is a type of tornado that is sometimes seen where
there is a strong heat source on the ground and the
atmosphere is unstable in the lowest kilometer [0.6
mile] or so near the surface," David Smart, a tornado
and storm researcher at University College London's
Hazard Centre, told Live Science.
"This seems to be a particularly well-formed and long-
lived example which might imply that atmospheric
conditions were particularly conducive on this day,"
Smart said.
As well as the tornado, the volcano has been causing
several explosions, according to the Icelandic
Meteorological Office. This is because pockets of
methane in the lava formed from the lava flow passing
over vegetation suddenly mix with oxygen and combust
explosively.
"It mixes with oxygen and when it runs into its glow or
flame from the fires there is an explosion," the
Meteorological Office explained in a translated
Facebook post.
It warned those observing the lava flows that these
explosions could be dangerous, urging people to steer
clear.
The volcano shows no signs of stopping its nascent
eruption yet. Shifting vent activity caused lava to
spill to the north and west of the collapsing volcanic
crater, while flow to the crater's south has lessened.
The flowing lava has also sparked a number of moss
fires, exacerbated by the dry weather over the past few
weeks.
Over 250 hectares of land have burned as a result, in
the largest moss fire of modern records, according to
the Icelandic Institute of Natural Science.
