This is and explosive volcano which means that the thick magma builds pressure until it blows the top off, gases carry, ash tephra and lava bombs, pyroclastic flow. There is a very high and thick silica content and there is a large amount of gas. Lots of water subducts turns to steam and build pressure.
This is Mount. Katmai and it is a composite volcano. An explosive period can release gas and ash forming a tephra layer. After this cycle of lava and tephra is repeated over and over in alternating layers. A composite volcano is formed. These type of volcanoes are mostly found where Earth's plates come together and one plate slides below the other.
This is an unbelievable experience. Thank you so much for taking me on this tour.
OMG!!!!! Its an Earthquake. I knew i Shouldn't have moved hear near the San Andres fault.
i think i can see the the Epicenter than the from here. That must mean the the focus is right underneath there. That means that i very close to wear the earthquake started. That's why the ground is rupturing over there.
