Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Kupfuura: Sezvo dutu remvura uye kuyerera kwokutanga kwepyrroclastic zvakanga zvichiri kufambira mberi, mbiru huru yemadota yakakura kusvika pakukwirira kwemakiromita 12 (19 km; 63,000 ft) pamusoro pemupata uri kuwedzera mumaminitsi asingasviki 10 uye yakaparadzira tephra mu stratosphere kwemaawa 10 akatevedzana. Pedyo negomo rinoputika, marasha ari mumhepo yakapoteredza nyika anokonzera mheni, idzo dzinopisa masango. Munguva iyi, zvikamu zveguruva remadota akaumbwa sehundi zvakawa, ndokudzokera pasi. Kuputsika uku, kwakasanganiswa ne magma, madhaka, uye chiutsi, kwakatuma mamwe mafashamo epyrroclastic achimhanya achidzika nemativi eSt. Helens. Gare gare, kuyerera kunononoka kwakauya zvakananga kubva mugomba idzva rakanga rakatarisana nechokuchamhembe uye kwaiva nemabhomba epumice anopenya uye madota epumiceous anopisa zvikuru. Mamwe eaya mafashamo anopisa akafukidza aizi kana kuti mvura iyo yakatsvaira kuva mhute, ichigadzira makomba anosvika mamita 20 muupamhi uye ichitumira madota kusvika kumamita 2 000 mumhepo.  Mubvunzo: Kuputika kwomusango kwakanga kuri kupi?
