Earthquake, tsunami, hurricane, volcanic eruption. Which is the most terrible?

Volcanic eruption is the most terrible, which can cause secondary disasters such as earthquake, tsunami (if at the seaside), strong convective weather, landslide, subsidence, debris flow and flood. During the eruption, underground CO2 and SO2 will penetrate into nearby rivers and lakes. Under the action of a lot of internal energy, rivers and lakes will become boiling stagnant water, and all living things in the water will be spared. The ejected volcanic ash can cover the sky, causing large-scale cooling. If it is a super volcano, it can cause global cooling, which is called "volcanic winter". Volcanic ash can also crush houses. If inhaled into the abdomen, it will cause serious damage to the respiratory system, and severe cases will die of lack of oxygen. The ejected magma can devour everything that passes by; The ejected volcanic bombs will cause great harm to buildings and human beings; The emitted SO2 meets cumulonimbus clouds to form acid rain clouds, which can burn everything on the ground. The fiery pyroclastic flow can reach 100- 150 miles per hour, and nothing grows anywhere!
