2020 is just a year of explosions. From the global coronavirus pandemic to wars getting erupted and other bad stuff, it looks like we cannot just get enough of this year.
Another event that we might get is a bang, not small, but a big bang.
The ice-covered covered Grímsvötn volcano is showing off signs of an eruption.
The threat has not yet reached to orange or red, but experts say that it is clear that the most active volcano in Iceland is getting ready to end this year with a bang.
Dave McGarvie, a volcanologist at the Lancaster University, said that there are clear signs of the volcano getting ready to erupt.
In a statement that was released to the public to explain the reason why they have decided to change the threat level of the volcano, they said:
Multiple datasets now indicate that Grímsvötn volcano has reached a level of unrest, comparable to that observed prior to historic eruptions. For these reasons, the aviation color code has changed from green to yellow. This does not mean that an eruption is imminent. However, an eruption could be triggered by depressurization if the subglacial lake inside the caldera will drain and cause a flood or occur regardless, possibly with very weak precursory activity and short warning time, as seen in the eruption of 2011. The conditions at the volcano may change at any given time and the volcano may return to normal background conditions without further escalation.
The volcano that we are talking about is really different.
The volcano lies entirely beneath the ice, and the only visible part is an old ridge that is located on the volcano’s side.
In 2011 the volcano produced a large and powerful eruption from the base of the exposed ridge.
The explosion sent ash 20 kilometers into the atmosphere and ended up causing the cancellation of nearly 900 passenger airplane flights.
After the eruption, scientists in Iceland have been monitoring the volcano for signs that it may erupt again in the future.
The volcano is reportedly inflating new magma.
Not only that, an increase in thermal activity has been observed due to the ice melting around the volcano.
An increase in earthquake activity has also been observed by the experts that are looking at the volcano.
Using knowledge from past eruptions, experts have determined that an intense swarm of the earthquake that lasts between 1 and 10 hours will be suggesting that the magma of the volcano is moving towards the surface.
This will also allow experts to know that eruption is imminent.
In the span of 800 years, the volcano has erupted 65 times.
