Stærð á Richter-kvarða (logaritmisk): hvert stig upp á við margfaldar orkuna sem losnar um ~32. Litir: grænn (M < 5, veldur sjaldan tjóni), gulur (5–5,9 í meðallagi), appelsínugulur (6–6,9 sterkur), rauður (7+ stór, mikil tjón). Dýpt í kílómetrum — því grynnra (allt að ~70 km), þeim mun meiri áhrif á yfirborðið. Opinber heimild: USGS.
USGS (United States Geological Survey): jarðfræðileg alríkisstofnun Bandaríkjanna, stofnuð 1879. Rekur þéttasta jarðskjálftanetið í heiminum og er frumheimild jarðskjálftaupplýsinga. Lén almennings.
Náttúruatburðir sem NASA rekur í næstum rauntíma: skógareldar, ofsaveður, eldfjöll, flóð, þurrkar, sjávarís, skriður og fleira. Táknið gefur til kynna tegund fyrirbærisins. Stærðin, þegar hún er til staðar, birtist í einingu uppsprettunnar — til dæmis flatarmál í acres fyrir skógarelda. Opinber heimild: NASA EONET.
NASA EONET (Earth Observatory Natural Event Tracker): þjónusta sem safnar og birtir, í næstum rauntíma, lýsigögn um náttúruatburði á jörðinni, tengd við samsvarandi gervihnattamyndir. Lén almennings (17 USC § 105).
Um tengla í þessum hluta: hvert atvik bendir á opinbera heimild skráða af NASA. Sum atvik birtast ÁN tengils vegna þess að heimild er IRWIN (Integrated Reporting of Wildland-Fire Information — kerfi Bandaríkjanna til að rekja skógarelda, sem krefst innskráningar); þess vegna væri ekki skynsamlegt að senda lesandann á lokuð aðgangsgátt. Aðrar heimildir birta hrágögn en opinber: JTWC (Joint Typhoon Warning Center — veðurvarnarstofnun Bandaríska hersins) birtir textafregnir með staðsetningu, styrk og spáðar brautir yfirveðursins, á tæknilegu sniði; NATICE (National Ice Center — þjóðlegt ísmiðstöð Bandaríkjanna) birtir CSV-töflureikni með öllum ísfjallsreksum — til að finna tiltekinn, leitaðu að línunni með nafnið sem sýnt er (til dæmis D33D). Heimildir eins og Smithsonian GVP (Global Volcanism Program — alþjóðlegt eldfjallaforrit) opna venjulega síðu.
