Lub roob hluav taws Eyjafjallajökull nyob rau sab qab teb ntawm Iceland (125 km ntawm Reykjavik). Eyjafjallajökull nce mus txog qhov siab ntawm 1666 m, thiab nws txoj kab uas hla yog 3-4 km (txog xyoo 2010 nws tau npog nrog dej khov).

Lub roob hluav taws tau txiav txim siab tsis nyob ntev txog 200 xyoo. Ua ntej yuav tsaug zog, Eyjafjallajökull tau tawg ib xyoos. Qhov tawg ntawm 2 cov ntsiab lus coj mus rau qhov dej khov ntawm cov dej khov ntawm tib lub npe.

2010 tawg

Eyjafjallajökull tau qhia nws cov haujlwm thaum kawg xyoo 2009: kwv yees li 1000 tshee tau sau npe hauv 3 lub hlis (1-2 ntsiab lus). Kev ntsuas GPS thaum kawg Lub Ob Hlis 2010 qhia pom tias lub ntiaj teb ua kiav txhab tau hloov 3 cm mus rau sab qab teb sab hnub tuaj. Kev ua haujlwm ntawm lub roob hluav taws tau nce ntxiv, nce mus txog qhov siab tshaj plaws thaum pib Lub Peb Hlis (txog 3000 tshee tshee tau sau tseg ib hnub). 500 tus neeg yuav tsum tau rov qab los ntawm thaj chaw ib puag ncig lub roob hluav taws vim muaj kev hem thawj ntawm dej nyab (dej khov tau pib yaj ntau) thiab lub tshav dav hlau Keflavik hauv lub nroog tib lub npe yuav tsum raug kaw.

Eyjafjallajökull tau pib tawg thaum Lub Peb Hlis 20, 2010, ua rau 0.5-kilometer rift nyob rau hauv cov dej khov (cov hmoov tshauv huab tau nce ib mais hauv qhov siab). Thaum Lub Peb Hlis 22, cov dej ntws ntws mus rau Hrunagil Hau, ua rau muaj kev poob qis lava. Thaum Lub Peb Hlis 25, dej nkag mus rau hauv qhov taub - muaj cov pa tawg thiab qhov tawg tau nkag mus rau theem ruaj khov. Thaum Lub Peb Hlis 31, qhov tawg tshiab tau tsim (ntev - 0.3 km), nyob 200 m ntawm thawj qhov. Tib hnub ntawd, lava hauv Hrunagil Hau khov. Txog rau lub Plaub Hlis 5, lava txuas ntxiv mus, tab sis los ntawm ob qho tawg (nws npog thaj tsam ntawm 1.3 square kilometers). Txog rau lub Plaub Hlis 7, lub lava los ntawm thawj lub qhov cua nres nchuav tawm.

Tom qab ntawd, kev ua seismic tau sau tseg rau lub Plaub Hlis 12 thaum 23:00 nyob hauv qab nruab nrab ntawm lub roob hluav taws. Thaum ib tag hmo, lub roob hluav taws tau tawg, ua kom muaj cov hmoov av 8 kilometers siab. Qhov no coj mus rau kev tsim ntawm lwm qhov tawg (nws qhov ntev yog 2 km). Kev sib tsoo ntawm cov dej khov ua rau dej nyab ntawm thaj chaw muaj neeg nyob thiab khiav tawm ntawm 700 tus neeg.

Lub Plaub Hlis 15-16, cov hmoov tshauv tau nce mus txog qhov siab ntawm 13 km, uas txhais tau tias nws tau poob rau hauv stratosphere. Thaum lub Plaub Hlis 17-18, qhov siab ntawm cov kem tshauv tau kwv yees ntawm 8 km, uas yog, nws tsis poob rau hauv stratosphere. Qhov kev tawg no ua rau raug ncua kev thauj mus los ntawm huab cua hauv Norway, Denmark, Sweden, thaj tsam sab qaum teb ntawm Great Britain (kwv yees li 6,000 lub davhlau raug tshem tawm thaum lub Plaub Hlis 15). Txog thaum kawg lub Plaub Hlis, kev ya dav hlau hauv thaj tsam ntawm European Union tau rov pib ua haujlwm, tab sis qee qhov kev txwv ntawm kev ya dav hlau tseem nyob rau lub Tsib Hlis. Feem ntau, qhov kev kub ntxhov ntawm xyoo 2010 tau kwv yees ntawm 4 cov ntsiab lus.

Nws yuav tsum raug sau tseg tias hauv 920, 1612, 1921-1823, kev tawg ntawm Eyjafjallajökull tau coj mus rau "ua kom" ntawm Katla (qhov nrug nruab nrab ntawm cov roob hluav taws yog 12 km), nrog rau ntau qhov geophysicists tso rau pem hauv ntej ib qho version uas tau tawg. ntawm Eyjafjallajökull rau xyoo 2010 yuav sai sai no thiab ua rau Katla tawg. Lwm tus kws tshawb fawb ntseeg siab tias xyoo 2010 yog ib qho ntawm cov kev sib txuas hauv cov saw hlau tawg uas yuav mus txog qhov kawg ntawm xyoo 2030. Tseem lwm tus ntseeg tias nws tseem tsis tuaj yeem kwv yees yuav ua li cas lub roob hluav taws yuav "coj tus yam ntxwv" yav tom ntej.

Cov lus tseeb nthuav txog Eyjafjallajökull

Raws li ib feem ntawm txoj kev tshawb fawb, Asmeskas cov kws tshawb fawb pom tias tsuas yog 0.05% ntawm cov neeg ntiaj teb tshaj tawm lub npe ntawm lub roob hluav taws raug. Rau qhov yooj yim ntawm kev cim lo lus Eyjafjallajökull, tus neeg hu nkauj Icelandic (Eliza Geirsdottir Newman) txawm tsim ib zaj nkauj tshwj xeeb. Tab sis hauv kev txhais lus Lavxias, kev hais tawm ntawm lo lus Eyjafjallajökull yog lub suab tsis raug.

Tus kws yees duab Sean Stijmeyer tau thaij duab ntawm lub roob hluav taws ntev, tom qab tsim cov vis dis aus los ntawm ntau txhiab daim duab uas tso cai rau koj pom tias Eyjafjallajökull tau hloov pauv li cas.

Eyjafjallajökull rau cov neeg ncig tebchaws

Cov pab pawg neeg tuaj ncig tebchaws tau raug coj tuaj rau lub roob hluav taws los ntawm cov tsheb npav, thiab kev ncig jeep tshwj xeeb kuj tau npaj rau lawv. Feem ntau cov pej xeem hauv nroog ua lub luag haujlwm ntawm tus neeg qhia - lawv coj lawv hla thaj chaw uas muaj lava ntws. Nws tsim nyog sau cia tias thaum taug kev taug kev, cov neeg taug kev yuav tsum kov yeej txog 17 km ntawm txoj kev.

Ib qho ntxiv, koj tuaj yeem txaus siab rau lub zog ntawm lub roob hluav taws los ntawm kev koom nrog hauv kev caij dav hlau nyoob hoom qav taub - koj yuav raug saib xyuas lub qhov ncauj ntawm lub roob hluav taws thiab cov cim tseg los ntawm lava hauv xyoo 2010 los ntawm qhov siab.

Cov neeg ncig tebchaws yuav tsum coj mus rau hauv tus account tias muaj ntau yam khoom txaus nyiam ntawm ko taw ntawm lub roob hluav taws:

  • Skougar lub zos (nto moo rau nws qub soddy farmsteads);
  • ib lub tsev khaws khoom pov thawj rau lub roob hluav taws;
  • Skogafoss dej tsaws tsag (nws qhov dav yog 25 m), "pub" los ntawm tus dej Skogau. Txog ntawm dej tsaws tsag, txhua tus tuaj yeem qhuas tus dej ntws los ntawm qhov siab 60-meter, nrog rau ib lossis ob tus zaj sawv.

Txoj kev taug kev uas nthuav tawm ntawm Eyjafjallajökull thiab Myrdalsjökull cov dej khov yuav ua rau cov neeg ncig tebchaws mus rau dej tsaws tsag Skogafoss. Ib qho ntxiv, nyob ib puag ncig ntawm dej tsaws tsag, nws yuav muaj peev xwm nrhiav chaw pw hav zoov.
