This is always a great event, #EuropeanResearchersNight in Reykjavík yesterday. Opportunity for scientists to interact directly with the public ❤️❤️ I was there for my astronomy club, but set up a seismometer so people could create an earthquake at the Veðurstofa Íslands / Icelandic Met Office booth 😊

Í kvöld eiga tunglið og Mars svo náið stefnumót að rauða plánetan hverfur á bak við tunglið. Nátthrafnar og árrisulir geta fylgst með myrkvanum sem hefst um klukkan 04:30 í fyrramálið og stendur yfir í klst. Tvíeykið verður því mjög þétt saman í fyrramálið. Horfið til himins! 🔭

🥺🥺🥺

Þetta er skemmtilegt, prófaðu að googla "loftsteinn" ☄️

Gullfalleg ljósadýrð á morgunhimninum. Glitský í 70 stiga frosti í heiðhvolfinu, mynduð með hjálp viðbótarvatnsgufu frá sprengigosinu í Hunga Tonga. Tjékk it át!

Stór skjálfti í Tyrklandi í nótt, 7,8 að stærð. Einn stærsti skjálfti sem hefur mælst þar í landi. Sprungan fyrir svona stóran skjálfta getur verið 200-400 km löng og áhrifin gríðarlega mikil. >170 x meiri orka losnaði úr læðingi heldur en í Suðurlandsskjálftanum 2008.

Áhrifasvæði skjálftanna í Tyrklandi í dag 💔 Stærsti skjálftinn var 7,8 en stærsti eftirskjálftinn var 7,5 sem er mjög stórt fyrir eftirskjálfta, en ekki óheyrt.

While keeping a close eye on #Askja caldera, let’s not forget just how amazing it is to have access to free satellite data, that has enough temporal and spatial coverage to deliver 6 images in the span of 10 days! #sentinel2 #landsat8 #landsat9 ❤️ USGS Landsat ❤️ Copernicus EU

Love this shot, something so Icelandic about it 💙

I challenge Robert F. Kennedy Jr Joe Rogan and Prof Peter Hotez MD PhD DSc(hon) to submit papers with data supporting their vaccine hypotheses which we will subject to open, public peer review by domain experts.

BIG NEWS IN PHYSICS! The first ever evidence for light year long gravitational waves that *might* be due to merging supermassive black holes. All possible thanks to pulsar timing arrays, explained in this video 👇 #GravitationalWaves #NANOGrav #pulsars

My favourite fact about the BIG gravitational wave news, is that it was only made possible because we finally know the precise position of Jupiter! 🤯 Thanks to chrislintott for flagging this cool fact #pulsartimingarray #nanograv #GravitationalWaves NASA's Juno Mission

Andri Yrkill fréttamaður var í miðjum fréttalestri um jarðskjálftahrinuna klukkan tíu í morgun þegar einn þeirra reið yfir. Þórunn Elísabet, annar stjórnenda Morgunvaktarinnar á Rás 1, gleymdi að loka fyrir hljóðnemann og lét þreytu sína með jarðskjálftahrinuna í ljós.

Everyone going on summer holiday in Iceland these days. Fagradalsfjall has other plans. Beautiful fringes showing where a dyke is intruding in the crust between Fagradalsfjall and Keilir. 18 cm deformation in direction of the satellite and over 6.000 earthquakes and counting

Accurate @NASPMON #earthquake locations from the start of the dyke intursion on 4 July as red dots. Triangles are seismic stations in the area. Our NASPMON stations are green, Veðurstofa Íslands / Icelandic Met Office is blue,Cambridge Earth Sciences is yellow. Iceland Geosurvey Czech Academy of Sciences TACR University of Iceland

Excellent thread

Since the #eruption began, the #earthquakes have moreorless stopped, and been replaced by seismic tremor. This is the incoherent background “hum” caused both by magma moving beneath the ground and venting at the surface - seen mainly at higher frequency (blue & green 2nd plot).

There she goes 🌋
