Disaster Readiness and Risk Reduction (DRRR) 13. Volcanic Hazards Volcanic Hazards and their Differences a. Lahar -mixtures of volcanic water and rock fragments which rush down the slopes of a volcano and into the surrounding valleys b. Ash Fall - consists of tiny jagged particles of rock and natural gas blasted into the air by a volcano c. Pyroclastic Flow - (pyroclastic density current) a fast moving current of hot gas and rock moving away from the volcano with the speed of 700 km/h or 450 mph d. Ballistic Projectile - rocks that an erupting volcano may hurl into the air - these blocks and bombs travel like cannon balls and usually land within 2 km of the vent - can travel as far as 5 km or even further if the eruption is very explosive e. Volcanic Gases - gases such as sulfur dioxide (SO2) and hydrogen s...
