- Plume awu saka letusan gunung berapi Great Sitkin setinggi 15,000 kaki (4,600m)
- Jeblugan kasebut sadurunge ana kerusuhan vulkanik-seismik sing luwih gedhe sajrone 24 jam sadurunge
- Gunung geni kasebut ngalami sawetara letusan sing ora suwe sajrone 100 taun kepungkur
The Survey Geologi AS (USGS) nerbitake sawijining pernyataan dina iki sing ngumumake manawa kegiatan vulkanik ing Pulo Great Sitkin wis dikonfirmasi kanthi data geofisik. Gunung geni wiwit njeblug jam 9:04 dina Selasa, kanthi bledosan suwene sawetara menit, lan terus meledak nalika nganyari paling anyar.
Letusan kasebut nyebabake USGS lan Observatorium Volcano Alaska (AVO) kanggo nerbitake 'peringatan abang' gabungan menyang penerbangan sawise pengamatan menehi saran yen wulu abu saka letusan gunung berapi Great Sitkin setinggi 15,000 kaki (4,600m).
"Wiwit jeblugan kasebut, seismisitas mudhun, lan gambar satelit nuduhake manawa awan awu wis pisah saka bolongan kasebut lan pindhah menyang sisih wétan," ujare Observatorium Volcano Alaska ing update paling anyar.
Sawetara foto ing media sosial, sawetara sing durung diverifikasi, katon nuduhake awan awu sing mandheg ing segara lan sawetara pulau terpencil. Siji gambar (ditampilake), bisa uga dijupuk saka komunitas Adak, udakara 26 mil (43km) sisih kulon gunung geni, nyorot ukuran ngeculake.
Jeblugan kasebut sadurunge ana kerusuhan vulkanik-seismik sajrone 24 jam sadurunge, lan suhu permukaan sing dhuwur lan belerang dioksida dideteksi sajrone seminggu kepungkur.
Great Sitkin minangka salah sawijining Kapuloan Aleutian, sing umume kalebu negara bagian Amerika Serikat ing Alaska. Gunung geni, sing akeh ana ing antarane Kepulauan Aleutian, wis sawetara letusan suwene sajrone 100 taun kepungkur, sing paling anyar yaiku ledakan uap cilik ing taun 2019.
APA sing kudu dijupuk saka ARTIKEL INI:
- 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.
- "Wiwit jeblugan kasebut, seismisitas mudhun, lan gambar satelit nuduhake manawa awan awu wis pisah saka bolongan kasebut lan pindhah menyang sisih wétan," ujare Observatorium Volcano Alaska ing update paling anyar.
