The Mount Semeru volcano It erupted between Saturday, December 3 and Sunday, December 4, one year after its last destructive eruption on the island of Java, Indonesia. The National Aeronautics and Space Administration (NASA) managed to capture the moment when the steam came out of the volcanic structure, this is how the event that occurred was seen from space. caused maximum alert.
This is what the eruption of the Mount Semeru volcano looked like from space!
According to him NASA Earth Observatorythe remote sensing instrument, Operational Land Imager-2 (OLI-2), in Landsat 9 captured a natural color image of a volcanic plume flowing from the Mount Semeru volcano at approximately 9:30 a.m. local time, on Sunday, December 4, 2022.
The POT captured volcanic columns They typically consist of ash and a mixture of volcanic gases, including water vapor, carbon dioxide, sulfur dioxide, hydrogen sulfide, and hydrogen halides. In this case, a towering convective cloud, perhaps drawing energy from the heat of the rashdarkened parts of the feather.
Diffuse ash slightly obscures the shadow of the large cloud and the underlying landscape further to the west in this larger version of the eruption photograph of the Mount Semeru volcano From space. In the lower part you can see a pyroclastic flow that descends through a river channel on the southeast flank of the mountain.
How destructive was the eruption of this volcano in Indonesia?
According to him NASA Earth Observatory, avalanches of superheated ash, tephra, earth and other debris rush at high speed and can cause great destruction. The eruption produced several of these flows, including one that reached a length of 19 kilometers, according to the Indonesian National Disaster Management Board (BNPM).
Heavy rains preceded the event, so pyroclastic flows would have mixed with rainwater and turned into muddy lahars as they rushed down the mountain. The flows destroyed a bridge and buried houses up to their roofs, according to Associated Press.
The eruption of Mount Semeru volcano hIt has forced almost 2,000 people to leave their homes. On December 4, the Center for Volcanology and Geological Hazard Mitigation (PVMBG) raised the status of the eruption from 3 (“alert”) to 4 (“caution”), the highest on the 1-4 scale.
- The PVMBG urged people to stay at least 5 kilometers from the summit and at least 500 meters from the channel of the Besuk Kobokan river.
Other satellite images of the Mount Semeru eruption
According to the portal Volcano Discoverythe POT managed to capture the eruption of the Mount Semeru volcano in Indonesia with other satellites at its disposal, including the Aqua, earth Y Suomi NPP.
Dozens of people died in the Mount Semeru eruption a year ago. In the most recent outbreak in December, no fatalities have been registered so far.
