Náttúrufræðingurinn 38 Þakkir Þessi grein er byggð á sprungukortlagningu sem höfundar hafa staðið að undanfarin ár ásamt Sigríði Magnúsdóttur, Bryndísi Brandsdóttur og Þór- hildi Björnsdóttur. Loftmyndir sem notaðar voru til verksins voru fengnar frá Loftmyndum ehf., Samsýn og Landmælingum Íslands. Jarðskjálftagögn fengust frá Veðurstofu Íslands og Raunvísindastofnun Háskóla Íslands. Hæðarlíkanið sem var notað í bakgrunni var TanDEM-X hæðarlíkan frá þýsku geimferðastofnunni (DLR). Kortlagning á vegum og vatnafari er úr IS50-grunni Landmælinga Íslands. Þessum aðilum öllum er þakkað fyrir aðstoðina, og einnig Halldóri Ólafssyni fyrir að heimila notkun 5. myndar. Heimildir 1. Clifton, A.E. & Kattenhorn, S.A. 2006.
