Question

Match the eruptive product from a volcano like Mount Saint Helens with the hazard associated with each.

Group of answer choices

Could melt snow cover or glaciers on stratovolcanoes, causing lahar flows.

      [ Choose ]            Lahars            Pyroclastic flows            Ash fall            Lava flows and domes      

Large volume of fast-moving ash-gas mixtures that can overrun topography, resulting in damage to areas near the volcano, which could include damage to infrastructure, forest resources and habitat.

      [ Choose ]            Lahars            Pyroclastic flows            Ash fall            Lava flows and domes      

Ash and sediment can be eroded and transported by in thick slurries of water released from volcano. Near the volcano, slopes can be stripped of vegetation and infrastructure, further from the volcano they can choke rivers and floodplains.

      [ Choose ]            Lahars            Pyroclastic flows            Ash fall            Lava flows and domes      

It is a hazard to plane engines so can cause disruptions to air travel.

Answer 1

1). Lava flows and Domes - Could melt Glaciers and snow covers on strato volcanoes, causing lahar flows.

2). Pyroclastic Flows - Large volume of ash - gas mixture that can overrun topography, resulting in damage to areas near volcano, which could include damage to infrastructure, forests and habitat

3). Lahars - Ash and sediment can be Eroded and transported by thick slurries of water released from volcano. Near the volcano slopes can be stripped off vegetation and infrastructure, further from the Volcano they can choke the rivers and flood plains.

4). Ash Fall - It is a hazardous to plane engines so can cause disruptions to air travel.
