Ruy dodani zilzila ba hodisai joyivazkunii moddai qismi boloii mantiya va tarqishu zud joy ivaz kardani qabathoi qishri Zamin vobasta meboshad. Zilzilahoi halokatovar va kharobiovar asosan dar khathoi shikastai qishri Zamin rukh medihand. Zilzilaho khosi mintaqahoi kuhhoi javon meboshand. Az hamin sabab zilzilahoi sakht dar nohiyahoi kuhsor ba vujud meoyand. Dar khamvoriho boshad, kam rukh medihand va quvvaashon sust ast.

Mahal va joi sathi qishri Zamin, ki dar boloi manbai zaminjunbi voqe gardidaastu az on jo mavjhoi takonhoi zerizaminy az poyon ba bolo rost harakat mekunand. markazi (epishentr) zaminjunbi nom dorad. Dar markazi zaminjunby kharobihoi beshtar ba vuqu meoyand. Dar joyhoe, ki az markazi zaminjunbi durand, lappishkho hamchun mavj ba khar taraf pahn meshavand va kudratashon nisbatan sust ast.

Binobar in dar baze mavzeho larzishhoi nachandon purshiddat his karda meshavand. Baze khonahoi kuhnai khishtiyu gili kharob megardand, darakhton khamu rost meshavand. digar khonahoi ohanu betoni asbobu anjom ba larza msoyand.

Seysmograf kalimai yunoni budya. “seysmos” – zaminchuiby, zilzila, “grafo” – menavisam ast. Masalan. dar Tochikiston khar sol to ss hazor bor zaminjunbiro qayd msnamoyand. Natijai mushokhidakho ba markazkhoi tadkiqoti ilmy baroi muayyan kardani markazhoi zaminjunbi firistoda meshavand. Az rui in malumotho olimon kharita va atlasi zilzilaro tartib medihand.
