World Distribution of Volcanoes

erm...;) aku cuma ingat Mt Fuji kat mana tu..lupa la...:lol letak la kat sini nama2 volcano yg still exist..dan locationnya sekali nak tau jugak...... meh listkan kat sini....

2/3 of world's volcanoes are located in the Pacific Ring of Fire = New Zealand, Indonesia, Philippines, Japan to Kamchatka on the western side of the Pacific Ocean, west coast of North & South Americas.

Pinatubo (Philippine), Krakatoa (Indon)... apa lagi ek?

eeh krakatoa, masih active ke?

Current Volcano status in New Zealand :

White Island is at alert level 1:
Signs of volcano unrest.


Mt Ruapehu is at alert level 1:
Signs of volcano unrest.


All other volcanoes are at alert level 0:
Usual dormant, or quiescent state.

mbhcsf

why not start by telling us a little bit more on PACIFIC RING OF FIRE?

Gunung Lipat Muda
Gunung Lipat Tua?


Jenis - jenis gunung berapai..
ada yg dormant
pendam and active  and also their different shape??

kan ..i last sekali ambil geog masa PMR ..tak ingat dahh...

bless you....

Pacific Ring of Fire tu terletak kat sekeliling Plat Pasifik, so negara-negara cam Jepun ngan Filipina tu banyak la gunung berapi...

Pasal gunung lipat tua ngan gunung lipat muda tu, kalau gunung lipat tu mengalami proses lipatan yang dah lama sangat dulu and then sekarang tak lagi, tu la dier gunung lipat tua, contohnya Banjaran Appalachian kat Amerika ngan Banjaran Titiwangsa. Gunung lipat muda lat sentiasa mengalami proses lipatan sebab terlepat kat sempadan plat bumi, contohnya Banjaran Himalaya.

Kat Hawaii..ada kan?? kalo tak silap...
volcano nih...

Kalau nak list gunung berapi .....ni yang aku teringat la

Merapi (Indon)

Mauna Kea (Hawaii)
Kilauea (Hawaii)
Paricutin (Mexico)
Etna (Itali)
Stromboli (Itali)
Vesuvius (Itali)
St Helens (US)

wow! mengalahkan national geographic..... he he
berfaedah la...thanks!

Current Volcanic Activity

Karymsky, Kamchatka, Russia
Fuego, Guatemala
Kilauea, Hawai'i
Tungurahua, Ecuador
Santa Maria, Guatemala
Sheveluch, Kamchatka, Russia
Dukono, Indonesia

Volcanoes listed above are currently erupting and the eruptions are on-going till today......

Tu baru diaorang berdehem tu....kalau dah BATUK nanti....

Tengok volcanic eruption ni kengkadang macam besstt aje (walaupun takut)..esp. tengok pyroclastic cloud. Very frightening, yet looks cool.....

sinbad^boy

kalau tak silap laa kan...letusan gunung berapi nih terjadik becoz of pergerakkan bumi.  

aku ingat2 lupa pasal geog nih...kalau tak silap..larva akan membentuk umm pulau2 baru contohnya macam kat hawaii... melalui letusan gunung berapi..larva akan di bawa ke laut...

tanah gunung berapi nih pun subur jugak..sebab contains byk nutriens utk pokok2..

About 550 volcanoes have erupted on Earth's surface since recorded history; about 60 are active each year. Far more have erupted unobserved on the ocean floor. Most volcanoes exist at the boundaries of Earth's crustal plates, such as the famous Ring of Fire that surrounds the Pacific Ocean plate. Fifty volcanoes have erupted in the United States since recorded history, and the United States ranks third, behind Indonesia and Japan, in the number of historically active volcanoes.

aku selalu kompius.... earthquake dgn gunung berapi :bgrin:

...

Nature of activity:

Active
+ it erupts frequently &
in recent times

Dormant
+ eruptions are infrequent

Extinct
+ does not erupt anymore or
has not erupted in historic times

====
Nature of materials:

Ash & Cinder Cone
+ steep-sided conical volcano formed
from ash & cinder

+ Eg Paricutin in Mexico

Lava Cone
+ shape of the volcano depends on
the viscosity of lava

+ Basic lava (shield volcanoes)
- gentle sloping volcanoes
- lava is fluid & solidify slowly
- Eg Mauna Loa in Hawaii

+ Acid lava (dome volcano)
- steep convex sides
- lava is viscous & solidify quickly
- Eg Mt Pelee in West Indies

Betul tu....

I suka tengok Discovery Travel Channel . Ada satu program tu ( tak ingat nama ) tunjuk hotel/vacation home yg dekat dgn Volcano. Jadi tetamu boleh lihat volcano dari bilik hotel tu....Very interesting....

meh kita tgk secara ringkas apa yang keluar bila letupan terjadi....

Images of Volcano Kilauea, Hawai'i

Pricipal types of volcanoes.


cinder cones



- bentuk paling simple
- terbentuk daripada partikel2 yang terpecah dari  lava yang dikeluarkan dari satu lohong yang menyejuk.


composite volcanoes



- typically sisi yang curam, bentuk yang simetri
-cth Mt Fuji, Mt St Helen


shield volcanoes



- terbentuk sepenuhnya dari aliran lava
- bentuk yang lebar, tidak curam,berbentuk kubah (domical shape)
- terbentuk dari aliran lava basalt yang mengalir jauh
- contoh jajaran guning berapi di kepulauan hawaii....Kilauea and Mauna Loa - gunung berapi yang aktif di sana



lava domes



- terbentuk dari aliran lava yang pekat so dia tak mengalir jauh berbanding ngan aliran yang membentuk shield volcanoes.
- contoh - Lesser Antilles (california)

kat venus pun ada ... called Venusian Volcanoes.


Pancake Volcanoes
Target Name:   Venus
Spacecraft:   Magellan

ni pulak Martian Volcanoes


The Majestic Olympus Mons
Target Name:   Mars
Spacecraft:   Viking



kat bawah ni pulak imej volcano kat bulan planet jupiter .. nama bulan tu Io
