collision domain first what is a collision maybe the question you have is what is the difference between a layer 2 and layer 3 broadcast collisions are considered part of the physical layer in the iso modelthe physical layer is the cablesan example would be copper also referred to as transmission media or mediumaybe the question you have is what is the difference between a layer 2 and layer 3 broadcast collisions are considered part of the physical layer in the iso model the physical layer is the cables an example would be copper also referred to as transmission media or medium
The Yellowstone Caldera is the volcanic caldera and supervolcano located in Yellowstone National Park in the United States, sometimes referred to as the Yellowstone Supervolcano. The caldera and most of the park are located in the northwest corner of Wyoming.iagram of the Yellowstone Caldera. The last full-scale eruption of the Yellowstone Supervolcano, the Lava Creek eruption which happened nearly 640,000 years ago, ejected approximately 240 cubic miles (1,000 km 3) of rock, dust and volcanic ash into the sky.
Amazingly, the caldera collapse didn't occur at the eruption vent, but 10 km away at Katmai, a stratovolcano! Apparently magma drained away from Katmai's magma reservoir to Novarupta's erupting vent. Yellowstone National Park consists of three enormous calderas that erupted about 2, 1.2, and 0.6 million years ago. The most recent caldera is 45 km across and 75 km long! Caldera-forming eruptions are the largest eruptions on Earth. For example, the Fish Canyon eruption in southwestern Colorado about 28 million years ago erupted more than 5,000 cubic kilometers of magma from the La Garita caldera.
