Tipe Letusan Gunung Berapi

• Letusan Tipe Hawaii

Tipe hawaii terjadi karena lava yang keluar dari kawah sangat cair, sehingga mudah mengalir ke segala arah. Sifat lava yang sangat cair ini menghasilkan bentuk seperti perisai atau tameng. Contoh: Gunung Maona Loa, Maona Kea, dan Kilauea di Hawaii.

• Letusan Tipe Stromboli

Letusan tipe ini bersifat spesifik, yaitu letusan-letusannya terjadi dengan interval atau tenggang waktu yang hampir sama. Gunung api stromboli di Kepulauan Lipari tenggang waktu letusannya ± 12 menit. Jadi, setiap ±12 menit terjadi letusan yang memuntahkan material, bom, lapili, dan abu. Contoh gunung api bertipe stromboli adalah Gunung Vesuvius (Italia) dan Gunung Raung (Jawa).

• Letusan Tipe Vulkano

Letusan tipe ini mengeluarkan material padat, seperti bom, abu, lapili, serta bahan-bahan padat dan cair atau lava. Letusan tipe ini didasarkan atas kekuatan erupsi dan kedalaman dapur magmanya. Contoh: Gunung Vesuvius dan Etna di Italia, serta Gunung Semeru di Jawa Timur.

• Letusan Tipe Merapi

Letusan tipe ini mengeluarkan lava kental sehingga menyumbat mulut kawah. Akibatnya, tekanan gas menjadi semakin bertambah kuat dan memecahkan sumbatan lava. Sumbatan yang pecah-pecah terdorong ke atas dan akhirnya terlempar keluar. Material ini menuruni lereng gunung sebagai ladu atau gloedlawine. Selain itu, terjadi pula awan panas (gloedwolk) atau sering disebut wedhus
gembel. Letusan tipe merapi sangat berbahaya bagi penduduk di sekitarnya.

• Letusan Tipe Perret atau Plinian

Letusan tipe ini sangat berbahaya dan sangat merusak lingkungan. Material yang dilemparkan pada letusan tipe ini mencapai ketinggian sekitar 80 km. Letusan tipe ini dapat melemparkan kepundan atau membobol puncak gunung, sehingga dinding kawah melorot. Contoh: Gunung Krakatau yang meletus pada tahun 1883 dan St. Helens yang meletus pada tanggal 18 Mei 1980.

• Letusan Tipe Pelee

Letusan tipe ini biasa terjadi jika terdapat penyumbatan kawah di puncak gunung api yang bentuknya seperti jarum, sehingga menyebabkan tekanan gas menjadi bertambah besar. Apabila penyumbatan kawah tidak kuat, gunung tersebut meletus.

• Letusan Tipe Sint Vincent

Letusan tipe ini menyebabkan air danau kawah akan tumpah bersama lava. Letusan ini mengakibatkan daerah di sekitar gunung tersebut akan diterjang lahar panas yang sangat berbahaya. Contoh: Gunung Kelud yang meletus pada tahun 1919 dan Gunung Sint Vincent yang meletus pada tahun 1902.

Welcome To My Life

oleh: Simple Plan

Do you ever feel like breaking down?Do you ever feel out of place?Like somehow you just don't belongAnd no one understands you?
Do you ever wanna runaway?Do you lock yourself in your room?With the radio on turned up so loudSo no one hears you screaming
No you don't know what it's likeWhen nothing feels all rightYou don't know what it's likeTo be like me
~Chorus~To be hurtTo feel lostTo be left out in the darkTo be kickedWhen you're downTo feel like you've been pushed aroundTo be on the edge of breaking downAnd no one's there to save youNo you don't know what it's like
Welcome to my life
Do you wanna be somebody else?Are you sick of feeling so left out?Are you desperate to find something more?Before your life is over
Are you stuck inside a world you hate?Are you sick of everyone around?With their big fake smiles and stupid liesWhile deep inside you're bleeding?
No you don't know what it's likeWhen nothing feels all rightYou don't know what it's likeTo be like me
~Chorus~To be hurtTo feel lostTo be left out in the darkTo be kickedWhen you're downTo feel like you've been pushed aroundTo be on the edge of breaking downAnd no one's there to save youNo you don't know what it's like
Welcome to my life
No one ever lied straight to your faceNo one ever stabbed you in the backYou might think I'm happyBut I'm not gonna be okayEverybody always gave you what you wantedNever had to work, it was always thereYou don't know what it's like, what it's like
~Chorus~To be hurtTo feel lostTo be left out in the darkTo be kickedWhen you're downTo feel like you've been pushed aroundTo be on the edge of breaking downAnd no one's there to save youNo you don't know what it's like
~Chorus~To be hurtTo feel lostTo be left out in the darkTo be kickedWhen you're downTo feel like you've been pushed aroundTo be on the edge of breaking downAnd no one's there to save youNo you don't know what it's like
Welcome to my life (x3)

Dear God

oleh: Avenged Sevenfold

A lonely road, crossed another cold state lineMiles away from those I love purpose hard to findWhile I recall all the words you spoke to meCan't help but wish that I was thereBack where I'd love to be, oh yeah
Dear God the only thing yo yeah I ask of you isto hold her when I'm not aroundwhen I'm much too far awayWe all need that person who can be true to youBut I left her when I found herAnd now I wish I'd stayed'Cause I'm lonely and I'm tiredI'm missing you again oh noOnce again
There's nothing here for me on this barren roadThere's no one here while the city sleepsand all the shops are closedCan't help but think of the times I've had with youPictures and some memories will have to help me through, oh yeah
Dear God the only thing I ask of you isto hold her when I'm not aroundwhen I'm much too far awayWe all need that person who can be true to youI left her when I found herAnd now I wish I'd stayed'Cause I'm lonely and I'm tiredI'm missing you again oh noOnce again.

Some search, never finding a wayBefore long, they waste awayI found you, something told me to stayI gave in, to selfish waysAnd how I miss someone to holdwhen hope begins to fade...
A lonely road, crossed another cold state lineMiles away from those I love purpose hard to find
Dear God the only thing I ask of you isto hold her when I'm not aroundwhen I'm much too far awayWe all need that person who can be true to youI left her when I found herAnd now I wish I'd stayed'Cause I'm lonely and I'm tiredI'm missing you again oh noOnce again
