1,000 - 1,500 feet Vertical drop from rim to floor at deepest points Shallow Magma Reservoir 5 - 10 miles deep Source of current ground swelling and geothermal activity The Role of Ancient Eruptions. Magma Chamber Depth It is crucial to distinguish between the depth of the caldera depression itself and the depth of the magma fueling it.
Exploring the Shallow Magma Reservoir Beneath the Caldera
Measuring the Depths Determining the exact depth of the Yellowstone caldera is not a matter of dropping a tape measure into a visible pit. To grasp its depth, one must first understand that this structure is essentially a giant, subsided bowl where the land surface dropped thousands of feet relative to the surrounding highlands.
This reservoir is what inflates the caldera today, but it is not the same as the ancient, collapsed void that defines the caldera's primary structure. Feature Depth/Measurement Notes Caldera Rim Elevation 8,000 - 10,000 feet Surrounding highlands formed by older volcanic flows Caldera Floor Elevation Approx.
Yellowstone Caldera Shallow Magma Reservoir Depth Explained
The Yellowstone caldera formed when repeated massive eruptions ejected enormous volumes of volcanic material, causing the overlying rock to fracture and sink into the emptied space below. The most precise data comes from seismic studies and ground deformation measurements collected by networks of GPS and satellite-based InSAR technology.
