- Ash plume mai le mauga mu o Great Sitkin e tusa ma le 15,000ft (4,600m)
- O le pa na muamua atu ma le alualu i luma o le mauga mu-seismic i le 24 itula talu ai
- O le maugamu na i ai ni nai pa pupuʻu i le silia ma le 100 tausaga talu ai
le US Suʻesuʻega o Fanua (USGS) tuuina mai se faamatalaga i le asō faasilasilaina o le gaioiga gaioiga i Great Sitkin Island ua faamautuina e geophysical faamaumauga. O le maugamu na amata ona pa i le 9:04 pm i le Aso Lua, ma le pa na pa ai le lua minute, ma na faaauau pea ona pa i le taimi o lana lata lata mai.
O le pa mai na mafua ai le USGS ma le Vaʻaia Volcano a Alaska (AVO) I le faʻailoaina o se 'lapataʻiga mumu' i vaʻalele ina ua maeʻa le maitauga na fautuaina ai le efuefu o le efuefu mai le mauga mu o Great Sitkin e oʻo atu i le 15,000ft (4,600m).
"Talu mai lena pa, ua faaitiitia le vaeluaina, ma o ata satelite ua faaalia ai o le lefulefu ua aluese mai le alavai ma o loo agai agai i sasae," o le Alaska Volcano Observatory fai mai i le lata lata mai.
O numera o ata i luga o upega tafailagi, o nisi e leʻo faʻamaonia, foliga mai e faʻaalia ai le lefulefu ao o loʻo tautau i luga o le sami ma le tele o motu mamao. Tasi le ata (faʻaalia), atonu na aumai mai le alalafaga o Adak, tusa o le 26 maila (43km) i sisifo o le maugamu, faʻamamafaina le tele o le lafoa.
O le pa na muamua atu ma le faateleina o le vevesi o le mauga mu-seismic i le 24 itula talu ai, ma le maualuga o le vevela o le eleele ma le sulfur dioxide na maua i le vaiaso ua tuanaʻi.
Great Sitkin o se tasi o Atumotu Aleutian, o le tele lava e aofia i le setete o Amerika o Alaska. O le maugamu, lea e tele i totonu o le Atu Aleutian, na iai ni nai paʻu puʻupuʻu i le 100 tausaga ua tuanaʻi, ma o se mea lata mai o ni tamaʻi pa pupusa i le 2019.
OA MEA E AVEA MAI LENEI TUSI:
- The eruption prompted the USGS and the Alaska Volcano Observatory (AVO) to issue a joint ‘red warning' to aviation after observations suggested the ash plume from the Great Sitkin volcano eruption was as high as 15,000ft (4,600m).
- Ash plume from the Great Sitkin volcano eruption was as high as 15,000ft (4,600m)The eruption had been preceded by increased volcanic-seismic unrest over the previous 24 hoursThe volcano has had a few short-lived eruptions over the past 100 years.
- "Talu mai lena pa, ua faaitiitia le vaeluaina, ma o ata satelite ua faaalia ai o le lefulefu ua aluese mai le alavai ma o loo agai agai i sasae," o le Alaska Volcano Observatory fai mai i le lata lata mai.
