Document Summary
Elastic rebound is when a fault is in the process of slipping and its storing large amounts of energy when all of a sudden, it snaps back into its original position, releasing said energy. Soft sediments have large amplitudes, slow vibrations and long durations of shaking. Stiff sediments have small amplitudes, fast vibrations and short durations of shaking. Cinder cones have medium viscosity, medium volatility and small volumes of magma. Shield volcanoes have low viscosity, low volatility and high volumes of magma. Stratovolcanoes have high viscosity, high volatility and high volumes of magma. Calderas have high viscosity, high volatility and ultra-high volumes of magma. Volcanic explosivity occurs when magma is highly viscous and high in gas content. This means there are more bubbles and there"s a large pressure gradient on the bubbles due to high viscosity such that fragmentation occurs, resulting in an explosive eruption. Causes are factors that lead to the instability of a slope.
