Volkeno blong Ambae: explosen mo ejecsen blong hot stone I semak long Yasur

Long manis blong Septemba, volkeno blong Ambae I stat blong wake ap mo VMGD oli rasem alert blong level blong Volkeno I ko long level 3. Hemi no rely klia long hao irapsen I divilop, volcano hemi I ko long phase blong explosive, I bildim wan taf kon long lak. Some long ol big  iven ia I generatem ol tal irupsen colum long aelan mo local ash we bai I foldaon. Hemi wan aktiviti we I no expected, base long historical aktiviti we oli luk long volkeno. Ol irapsen blong mid septemba  2017 hemi semak long hemia long 2005. Same kind blong irapsen ia oli observem vinis long 2005. Some pat blong aelan oli experiencem ol ash we I foldaon olsem same irapsen ia. Some style blong irapsen be I bin change long 22 septemba taem we ol staff blong Geohazard oli observem lava long surface blong fes taem. Hemi I wan impotant jens mo i kat incertitude blong raised ap abaiot divilopmen blong irapsen. So alert blong level blong volkano oli tekem long same taem. Implikasen blong lava we I stap long surface I no kila. Ol falet we oli mekem observasen long saturdei 30 septemba mo sandei 1 octoba oli some se aktiviti blong volkano I apen nomo long wan summit crater lakes ( Lake Voui).  Ol photography mo ol thermal infrared image we oli tekem during long observasen flaet I some se aktiviti I consist long explosen mo injecsen blong hot stone, we bai I semak long same experiense long Yasur volkeno long Tanna. Lokal populasen oli arem some explosen mo luk laet long hill long same taem.  Satellite data mo ol observasen flaet ol confirmem se nao se I kat some smol lava I flows long niu volkeno aelan, hemi kasem lake.  I kat wan smol scoria kon long aelan mo naba blong iven bai I save jenis daily. Long trifala dei we I pass, hem blong putum aot ol data blong tu seimic blong Ambae mo long wan web kamera (http://www.vmgd.gov.vu/vmgd/index.php/geohazards/volcano) . Ol data ol transmited 24 haoa long wan dei. Aktiviti blong seimic hemi riflectem niu movemen blong lava tru long volkeno and reckting blong lava mo I mix wetem geothermal system ( wan smol incrise). Data blong seismic hemi no soem big mo big incrise blong aktiviti blong volkeno blong Ambae. Ol scientific blong VMGD bai oli monitarem aktiviti ia closap taem we oli stap long Port Vila, tru long instrument we oli stap long Ambae mo long ol aelan we I nid blong usum. Volkeno blong Ambae hei wan bigfala volkeno mo hemi frequenly active. Long ricord blong histri , I bin kat fulap eraspsen, every 10-50 yia mi I kat similar explosive aktiviti  every 100 to 150 yia. Every wan I kam long samit krata, oli expectem long wan ricord blong 1670 we lava I flow I occurred colosap long Ndui Ndui vilij. Karen irapsen ia I fokas long samit krata, I no kat indicasen blong aktiviti long diferen place long aelan blong Ambae. I kat wan nuifala observasen long 30 septemba mo long 1st octoba I confirmem se situasen bai I no divilop more. Olsem naoia activity I fokas nomo long nuifala aelan blong lake voui. Possibility blong bigfala iraspsen bai I save affectem ful aelan mo naoia I luk les laek. VMGD bai I kontinu blong provaedem apdei long pablik mo kavman long situasen envolve.
