Volcanic flows are dangerous due to their high temperatures, fast speeds, and destructive potential. They can cause widespread damage to infrastructure, homes, and vegetation in their path. The heat from volcanic flows can also pose a severe threat to human life by causing burns, asphyxiation, and respiratory issues. Additionally, volcanic flows can trigger other natural hazards such as landslides, tsunamis, and lahars, which further increase the danger to nearby communities. It is important to heed evacuation warnings and stay informed about volcanic activity to stay safe in the event of a volcanic flow.
