Mount Sourabaya, a volcano that has been quiet for the last 60 years, has spewed lava and hot ashes. The volcano’s eruption was only witnessed by NASA since no one can see the fiery eruption on the island as no civilisation exists there.
The volcano is located on Bristol Island which is a part of the South Sandwich Islands chain in the South Atlantic Ocean. The island chain is stretched up to 1,725 miles south-east of Buenos Aires, Argentina. This is the estimated distance between Los Angeles and Chicago. The highest peak on the island is 1100 metres above the sea level. The tall and conical volcano stands 3600-foot and is covered with snow and ice.
The volcano erupted for at least two days. One eruption occurred on April 24 and other on May 1. The images were captured by Operational Land Imager (OLI); NASA’s Landsat 8 satellite, which passed over the island.
“The images were built from a combination of shortwave infrared, near-infrared, and red light (Landsat bands 6-5-4) that helps detect the heat signatures of an eruption,” reported NASA.
The Weather Channel reports that the volcano, Mt. Sourabaya last erupted in 1956. And it was just now that it radiated heat and lava after 6 decades or so. The images indicate the lava in orangish-red colour, white smoke shows the ash and the blue-green colour shows the covering of ice.
Volcanic eruptions at remote places like Atlantic barely come into notice. But with the help of satellite and monitoring system, scientists are able to pick up even minor activities with accuracy.
“Today, scientists can pick up signatures of events occurring far from any human observers,” said NASA.
Due to the remoteness of human civilisation, the volcano is least-studied, according to a report filed by Fox News.
“There are no human residents of the island, which is almost always covered in glacial ice and snow,” said NASA.
