https://www.cnn.com/2024/04/23/climate/indonesia-volcano-eruption-weather-impact/index.htmlWhen Mount Ruang in Indonesia underwent multiple explosive eruptions last week, volcanic gases were flung so high they reached the atmosphere’s second layer, tens of thousands of feet above ground.
The force of Mount Ruang’s eruptions this week ejected an ash plume tens of thousands of feet in the air and sent some volcanic gases more than 65,000 feet into the air, according to satellite estimates – about 25,000 feet higher than a commercial airplane will typically fly.
Indonesian volcano eruptions force thousands to evacuate as airlines cancel flightsRenewed eruptions from a remote Indonesian volcano have triggered fresh evacuation orders and sparked flight cancellations and airport closures this week with smoke, lava and volcanic gasses spewing out of the fiery mountain.
Mount Ruang, a 725-meter (2,400-foot) volcano on Ruang Island, North Sulawesi, has been erupting in spectacular fashion on and off since mid-April, posing a growing threat to those living nearby and to air traffic in the region.
The volcano erupted three times on Tuesday, sending lava and ash clouds into the sky and prompting Indonesia’s national PVMBG volcanology agency to issue its highest alert, warning that a tsunami could be triggered by “volcanic material collapsing into the ocean.”
The large eruption at Ruang volcano was primarily caused by the movement of magma within the Earth's crust, which led to increased pressure and the eventual release of gas and magma through the surface. This geological activity is typical of stratovolcanoes, where the buildup of pressure can lead to explosive eruptions.
The eruption had significant effects on the surrounding areas, including ashfall, pyroclastic flows, and potential lava flows. Ashfall can disrupt air travel, damage crops, and pose health risks to residents. Additionally, the eruption may have forced evacuations and disrupted local infrastructure.
Authorities are monitoring the volcano using a combination of seismic activity measurements, satellite imagery, and ground-based observations. They also assess gas emissions and thermal activity to evaluate the volcano's status and provide timely warnings to local communities.
Residents are advised to stay informed through official channels, avoid areas with heavy ashfall, and wear masks to protect against respiratory issues. They should also prepare for possible evacuations and have emergency supplies ready in case of further volcanic activity.
While it is difficult to predict specific eruptions, Ruang volcano is considered active, and future eruptions are possible. Continuous monitoring and research are essential to understand the volcano's behavior and assess the risks to nearby communities.
