Phakathi namahora angu-24 ngemva kokuzamazama komhlaba okuyi-8.3 magnitude kuze kube manje osekubulale abantu abangu-119 eSamoa nase-American Samoa, kuye kwagadla okunye ukuzamazama komhlaba okunamandla. Kulokhu, ukuzamazama komhlaba okunamandla ku-7.6-magnitude esikalini sikaRichter, kuhlasele ogwini lwaseSumatra futhi kuze kube manje sekubulale okungenani abantu abangu-75 futhi kwavale izinkulungwane ngaphansi kwemfucumfucu nemfucumfucu, ngokusho kwezikhulu zase-Indonesia.
Kubikwa ukuthi ukuzamazama kweSumatra kuthumele amagagasi amangalisayo emazweni angomakhelwane iSingapore neMalaysia futhi kwadala ukwesaba ukuthi kuzokwenzeka enye i-tsunami emazweni azungeze uLwandlekazi i-Indian. Isexwayiso se-tsunami saqale sakhishelwa isifunda, kodwa sahoxiswa ngemuva kwamahora ambalwa.
Isazi sokuzamazama komhlaba sase-US Geological Survey's National Earthquake Centre u-Randy Baldwin uqinisekise ukuthi ukuzamazama komhlaba kwe-Samoa ne-Indonesian bekungahlobene. "Kunebanga elincane elihlukanisa ukuzamazama okubili okuhlukene, abukho ubudlelwano," etshela izintatheli. “Kuyindawo ematasatasa yonke indlela ezungeze umngcele woLwandlekazi iPacific.”
Ngokusho kukaBaldwin, ukuzamazama kwaqala endaweni engamakhilomitha angu-31 enyakatho-ntshonalanga yedolobha lasePadang eningizimu yeSumatra. Le ndawo isendleleni efanayo neyabangela i-tsunami enkulukazi yase-India Ocean yango-2004 eyabulala abantu abangaphezu kuka-230,000.
Ngokuhlukana, okunye ukuzamazama komhlaba kuhlasele iPeru neBolivia. Lokhu kuzamazama kwe-6.3-magnitude kuhlasele eningizimu-mpumalanga yePeru, eduze nenhloko-dolobha yaseBolivia iLa Paz, kubika i-US Geological Survey. Ngokwemibiko, ukuzamazama, okujule ngamakhilomitha angu-160.3, kwenzeka cishe ngamamayela angu-100 enyakatho-ntshonalanga yeLa Paz.
