During volcanic eruptions in #Iceland the scientific community relies on The Icelandic Coast Guard for support during the first phase of events. Their fleet includes a #Bombardier Dash-8 turboprop equipped with a side-looking radar + camera systems. Today we did some training looking at volcanoes 🌋 🛩️

More thermal infrared images from #Landsat 😍

This image was acquired last night covering NE part of #Iceland

Partially clouded but lots of interesting things visible like the geothermal areas near Kverkfjöll and Þeistareykir.

Images with and without a hillshade blend.

@wikkit Well, the reason there is an island where Iceland is located (and not elsewhere on the ridge) is because there is also a hot spot underneath: https://en.wikipedia.org/wiki/Iceland_hotspot

May annual #earthquake map 🎇

#Iceland is situated on the Mid Atlantic Ridge making it a very volcanically active. The ridge cuts the island in half from SW to the NE, slowly spreading it a part. Here are all the ~30000 earthquakes that have been verified and checked by the Icelandic Met Office staff

Yet another beautiful ascending night-time image from #Landsat looking at the eruption site on #reykjanes peninsula. This is brightness temperature for band 10 (thermal infrared) acquired last night around 22:30. Outline for the most recent lava shown.

A great example of a suggessful cross agency collaboration! The remote sensing team lead by Joaquín and Birgir has played a key role in delivering important data for monitoring and model inputs for us at Icelandic Met Office. The Photogrammetry Lab at Icelandic Institute of Nature Research runs an extremely efficient operation with a fast response time, delivering high resolution ortho images and DEMs.

We are now in midst of the 7th #eruption near the Svartsengi power plant. The most cost-effective instrument in monitoring an ongoing eruption is a camera. The Icelandic Met Office deploys quite a few cameras. This is a timelapse from our lates #PTZ camera looking westwards towards the eruption site.

Second eruption near #Grindavík ongoing. The eruptive fissure is closer to the town than the first eruption and has now cut the lava barrier that was being constructed. Photos for the Icelandic Coast Guard and the Civil Protection.

Night-time helicopter flight with The Icelandic Coast Guard gathering info and estimating the extent of the lava field in the early phase of this eruption.
