Day six of the sixth eruption near #Svartsengi and the town of #Grindavik This eruption is the largest one yet. Here is a 4-day series of #Sentinel5p satellite data from the #TROPOMI instrument showing the mean amount of SO₂ in a vertical column of atmosphere (Dobson units).

@RagnarHeidar @felt As a person of Icelandic descent who is designing Felt, it's great to see it getting used over there!

Finally found a good reason to use @felt Made a map for a kid’s football tournament where my 7yr old twins participated. Shared with all parents. Where are all the different pitches? Where is the accommodation? Where is the campsite? Just look at the map 👇🏼⚽️🗺️

@pallih Minnir mig á þegar ég var að vinna við staðfangaskrá New York borgar. Eitt hús gat t.d. verið með 5 heimilisföng: Holland Ave 33 Holland Ave 33a Holland Ave 33½ Holland Ave 33⅓ Holland Ave 33¼ Þessi ⅓ var stórhættulegar ef féll í þá grygju að reyna eiga við þetta sem tölur

@pallih Gott Svoldið eins og að vinna með gögn frá gömlu Unix köllunum. Nota max 3 stafi í skrár- og möppunöfnum. 4 í algjörri neyð. Dæmi is=Ísafjörður

Super nice to have weather radar data available in @Windycom directly from @Vedurstofan in their app. Perfect for timing my morning commute 🚲 Will start this morning at the home desk. See rainfall arriving in reply 👇🏼

The false color near infrared band combination for #sentinel2 is very useful when looking at proglacial lakes. The lighter colors tell us that the lake is being actively filled with glacial meltwater. In some situations, this might lead to floods if there is no active outlet.

@subglacial Nice capture of Svínafellsjökull. We @Vedurstofan try our best to keep a close eye on the still unstable north facing slope! This includes extensometers across some of the surface faults 👇🏻

Fór með skóflu niður í bæ og gróf djúpa holu. Er þakklát fyrir að hafa ekki verið skotin þrátt fyrir að hafa haft skóflu að vopni (Djók). Annars má hér sjá sögu Reykjavíkur - frá landnámi til dagsins í dag. #fornleifatwitter #Skólabrú
