UMURI ZILZILA

UMURI ZILZILA, majmui tadbirhoest, ki az mushohidahoi muttasili zilzila va tahlili malumot (az rui programmahoyu metodikai standarti) iborat ast. Mushohidaho dar stansiyahoi seysmiki guzaronda meshavand. Vazifai asosii umuri zilzila muntazam muayyan namudani parametrhoi asosii markazhoi zilzilaho (koordinathoi gipomarkaz, paydoishi zarba dar markaz, tavsifi energetiki va gayra) iborat meboshad.

Dar yak qator mamlakalhoi jahon umuri zilzila mavjud ast, dar SSSR Sistemai yagonai mushohidai seysmiki (SYaMS), dar PGMA Umuri seysmikii milli (USM), dar Yaponiya Agentii meteorologii Yaponiya (AMYa) tashkil karda shudaand. Markazhoi seysmologii milli materialhoi mushohidahoi stansiyahoi mamlakathoi alohidaro jambast menamoyand. Baroi batafsil omukhtani zilzilanoki umuri zilzilai regionali tashkil karda meshavad. Umuri zilzilai baynalkhalqiro Markaai seysmikii baynalkhalqi dar Britaniyai Kabir meguzaronad, ki dar on malumoti aksar stansiyahoi zilzilasanjii mamlakathoi jahon jambast meshavad. Az stansiyaho ba markazhoi seysmologi oid ba vaqti dokhilshavi va amplitudai mavjhoi zilzila malumot doda meshavad. Sipas malumoti seysmologiro dar hisobmoshinho kor karda, koordinathoi gnnomarkaz va mzgnitudai zilzila muntazam muayin karda meshavad. Malumoti mushohidahon umuri zilzila baroi omukhtani zilzilanoki va sokhti Zamin, inchunin baroi omukhtani prosesshoi markazi zilzila istifoda meshavad.
