weakness, There are two conditions that lead to a weak volcanic eruption, low viscosity magma and little presence of trapped gases.
strength, The VEI or (Volcanic Explosivity Index) is a scale that describes the size of explosive volcanic eruptions based on magnitude and intensity. The numerical scale (from 0 to 8) is a logarithmic scale, and is generally analogous to the Richter and other magnitude scales for the size of earthquakes.
