The 15 pages that link to Pyroclastic density current, each with the reason it gives.

• Volcanic hazardRelated: These currents can overwhelm communities through heat, impact, and burial within minutes.

• LaharCompared with: Unlike a lahar, it is driven by hot gas and does not require water.

• Pyroclastic flowNarrower topic: Pyroclastic flows are dense, ground-hugging examples of this broader class of currents.

• PompeiiRelated: Such currents reached Pompeii during the eruption and caused lethal heat exposure.

• Mount St. HelensRelated: After the blast, hot currents swept outward and devastated areas around the volcano.

• Volcanic hazard mapBroader topic: Its speed, heat, and ability to travel far make its hazard zones distinctive.

• Volcanic riskBroader topic: Its speed, heat, and reach make it a major source of immediate life-safety risk.

• Mount VesuviusRelated: These deadly currents overwhelmed settlements around Vesuvius during the AD 79 eruption.

• Plinian eruptionRelated: A collapsing Plinian column can generate these lethal flows.

• Explosive eruptionBroader topic: Column collapse can send this lethal mixture racing down a volcano’s slopes.

• HerculaneumNarrower topic: These currents buried Herculaneum and caused the sudden deaths of many inhabitants.

• Lesser Antilles Volcanic ArcRelated: These currents pose a major danger around steep arc volcanoes.

• Mount PeléeNarrower topic: The current that devastated Saint-Pierre belongs to this broader class of volcanic flows.

• 1902 eruption of Mount PeléeNarrower topic: The disaster’s deadly flow helped bring this class of hazards into scientific focus.

• Eruption of Mount VesuviusNarrower topic: Such currents delivered lethal heat and debris to towns near Vesuvius.
