See the activity of an Icelandic volcano from space

The researchers used the largest ever synthetic aperture radar (SAR) constellation. This

fourteen spacecraft thatply around the globe. Scientists used their function to return to the same place, which allowed them to view the volcano's mouth from the same height and from the same angle.

This gives the satellite train imagery"Connectivity". They can be compared to catch the slightest changes in any area. They used this feature to study the eruption of the Icelandic volcano Fagradalsfjall.

The researchers note that many have already observedfor volcanic eruptions (even live), but Iceye gives you the opportunity to look at Fagradalsfjall from above and trace how the molten rock spreads from the vent. In the video, you can also see other objects that form along the clear line of cracks.

“What we do is called dailya repetition of the ground track, explained Iceye CEO Rafal Modrzewski. - To do this, you need to adjust the orbit of the satellite so that it does not cover the entire Earth. So it will cover only one-sixth of the world. "

Also in the company data you can seeFagradalsfjall's interferogram. It is compiled by comparing two precisely aligned images from different flights over the same location.

By the colored borders, scientists can determine whereand how much the ground under the satellite has moved. This method is especially useful in volcanology for tracking convex underground magma chambers, or in earthquake studies to track faults that are not always visible on the surface during strong tremors.
