Geophysical hazards: volcanic eruptions. Definition and characteristics. Volcanic eruptions happen when lava and gas are discharged from a volcanic vent. The most common consequences of this are population movements as large numbers of people are often forced to flee the moving lava flow.Volcanic eruptions often cause temporary food shortages and volcanic ash landslides called Lahar.The most dangerous type of volcanic eruption is referred to as a 'glowing avalanche'. This is when freshly erupted magma forms hot pyroclastic flow which have temperatures of up to 1,200 degrees.he most common consequences of this are population movements as large numbers of people are often forced to flee the moving lava flow.
