A volcano that sat dormant for almost a century erupted suddenly on Saturday and astronauts aboard the International Space Station were able to capture some incredible images of the violent explosion.
From their outer-space vantage point, they captured a seldom seen perspective of the vigorous eruption of Raikoke. On June 22 at approximately 4 a.m. local time, Raikoke exploded for the first time since 1924, expelling a dense plume that could be seen from the ISS, NASA Earth Observatory reported. It sits on the Pacific Ring of Fire, where the Pacific tectonic plate meets other tectonic plates and where most of the worlds' earthquakes and volcanic eruptions take place.
As reported by "FACTS", in early June, Indonesia's North Sumatra erupted volcano - woke up mount Sinabung (Sinabung).
Several satellites - as well as astronauts on the space station - observed as a thick plume rose and then streamed east as it was pulled into the circulation of a storm in the North Pacific. The top of the ash cloud is flat because the density of the cloud has equalized to the density of the surrounding atmosphere, and the cloud's stopped rising.
Simon Carn, a volcanologist at Michigan Tech said: "What a spectacular image".
The official also noted that the ring of clouds at the base of the volcano appears to have been formed by the condensation of water vapor. The plume from the eruption may have reached an altitude of 8 miles high, according to the Volcanic Ash Advisory Centers in Tokyo and Anchorage. "Or it could be a rising plume from interaction between magma and seawater because Raikoke is a small island and flows likely entered the water". The ash flung up by volcanoes contains fragments of rock and glass, posing a serious hazard to aircraft. The Terra and Suomi NPP satellites, operated by NASA and the United States National Oceanic and Atmospheric Administration respectively, also managed to capture photos of the incident. Before that, it last erupted in 1778, NASA said.
