Ukuqhuma okuqine kakhulu kunokwejwayelekile kuthathwe kumakhamera aqhutshwa yi-Istituto Nazionale Geofisica e Vulcanologia (INGV). Izithombe ezabiwe ngu-Il Mondo dei Terremoti ku-Twitter zikhombisa ukuqhuma ngesikhathi sangempela; ividiyo ethathwe ngamakhamera we-infrared abonisa ukuqhuma kokuqala kwe-ultra-hot kanye nefu elipholile kancane lomlotha namagesi alungisa phansi. Lesi siga somlotha oshisayo namagesi saziwa njengokugeleza kwe-pyroclastic.
Ukusuka edolobhaneni, bekungabonakala intuthu yomlotha ebabazekayo ephakama ngamamitha ayi-100 ngaphezulu kwengqungquthela. Ngokushesha ngemuva kokuqhuma, imvula yomlotha enamandla ngokulinganisela yama-lapilli amancane yaqala ukungena, ehlanganisa yonke indawo.
Umbala wezinhlayiya eziningi, ongafika kumamilimitha ambalwa ngosayizi, ubuningi bawo ubunsundu ngokusobala ngokubomvu ngokubomvu, ochazwe njengo “mhlaba”. Lokhu kungasho ukuthi iningi lezinto ezikhishiwe kungenzeka ukuthi zivela emadwaleni amadala odaka lwentaba emhlanganweni noma ngaphakathi komoya, kusuka ezingxenyeni eziwohlokile zemigodi noma imigudu. Kodwa-ke, inani elincane le-pumice elula lalikhona emlotheni, mhlawumbe omele iqoqo le-magma elisha eliqhube ukuqhuma.
LOKHO ONGAKUTHATHE KULESI SIHLOKO:
- However, a small amount of lighter pumice was also present in the ash, probably representing a batch of fresh magma that had driven the explosion.
- This could mean that most of the ejected material might be from older lava rocks in the summit craters or inside the vent, from collapsed parts of the craters or conduits.
- The color of most particles, up to a few mm in size, was mostly brown to reddish brown, described as “earthy”.
