S\u00f8ndag morgen klokka 09.25 ble hele \u00d8stlandet p\u00e5virket av jordskjelv, og mandag har Norsar forel\u00f8pig estimert jordskjelvets posisjon til 60.1917,11.316, i Nes ved Br\u00e5rud.<\/p>\n

\u2013 Episenteret kan flytte litt p\u00e5 seg. Vi jobber med lokalisering. Den f\u00f8rste analysen er usikker, og vi trenger \u00e5 bruke litt mer tid. Episenteret kan flytte seg med 10-20 km, jo mer data man legger inn, forteller Annie Jerkins, seismolog ved Norsar.<\/p>\n

Hva er et episenter?<\/p>\n

Episenteret er det punktet p\u00e5 jordoverflate som er direkte over der jordskjelv skjer i undergrunnen. St\u00e5r du rett i episenteret merker du det mest.<\/p>\n

Lyden av et jordskjelv<\/p>\n

Jerkins har en enkel forklaring p\u00e5 hvorfor flere h\u00f8rte et brak under g\u00e5rsdagens jordskjelv.<\/p>\n

Hun forteller at folk ofte rapporterer om h\u00f8ye lyder ved jordskjelv.<\/p>\n

\u2013 Det du h\u00f8rer er lyden av jordskjelvet. Lyden kommer fra bakken, forteller hun.<\/p>\n

Etterskjelv<\/p>\n

Fordi jordskjelvet s\u00f8ndag ikke var s\u00e5 kraftig, blir etterskjelvene heller ikke kraftige.<\/p>\n

De fleste vil v\u00e6re umerkelige.<\/p>\n

\u2013 St\u00f8rrelsen av jordskjelvet p\u00e5virker hvor kraftig og hvor mange etterskjelv kan oppst\u00e5. Ved st\u00f8rre jordskjelv kan man f\u00e5 ganske betydelige etterskjelv, flere timer eller dager etter. Ved mindre jordskjelv vil ogs\u00e5 etterskjelvene v\u00e6re sm\u00e5, forteller Marco Br\u00f6nner, geofysiker, Norges geologiske unders\u00f8kelse (NGU).<\/p>\n
