    See english text below. Myndkort af atburðum sem hafa átt sér stað á Reykjanesi frá árinu 2021 hafa orðið til í samstarfi Náttúrfræðistofnunar Íslands, Landmælinga Íslands, Veðurstofu Íslands, Jarðvísindastofnunar og Almannavarnir, sem hluti af viðbragðsáætlunum, hættumati og rannsóknum. Hingað til (febrúar 2024) hafa sex eldgos frá tímabilinu 19. mars 2021 til 14. janúar 2024. Í öllum atburðum voru teknar loftmyndir vikulega og hæðarlíkön útbúin ásamt myndkortum. Myndkortin eru aðgengileg í gegnum WMS þjónustu og á Umbrotasjá (https://kortasja.lmi.is/mapview/?application=umbrotasja) innan við sólarhring eftir gagnasöfnun. Gögnin eru uppfærð jafnt og þétt, eða þegar nýjar upplýsingar berast á meðan á gosinu stendur. Nánari upplýsingar má finna í samantekt um eldgosið frá 2021, sjá: Pedersen o.fl., 2022. - - - - Orthomosaics of the events occuring in Reykjanes since 2021 have been created in a collaborative effort between Nátturfræðistofnun Íslands, Landmælingar Íslands, Veðurstofa Íslands, Jarðvísindastofnun and Almannavarnir, as part of the response plans, hazard assessments and research. Up to date (February 2024), we have documented six eruptions. The first started in 2021, March 19th and the most recent one 2024 in January 14th. The first three eruptions were documented in Fagradalsfjall (March-September 2021, August 2022, July 2023), a dyke intrussion and graben formation in Grindavík (November 2023) and two eruptions in Svartsengi (December 2023, January 2024). On each event, we collected aerial photographs weekly, and produced Digital Elevation Models (DEMs) and orthomosaics of these events. The orthomosaics are available via WMS and in the Umbrotasjá webpage (https://kortasja.lmi.is/mapview/?application=umbrotasja) less than one day after data collection. The data is updated constantly, or when new information is received during the eruption. A publication showing this work was done for the 2021 eruption, for further details see: Pedersen et al., 2022. Reference: Pedersen, G. B. M., Belart, J. M. C., Óskarsson, B. V., Gudmundsson, M.
