Question

Stratovolcanoes can create several volcanic hazards both during and after eruption events. Based on the animation, place the following volcanic hazards in chronological order based on when they would likely impact a town near the volcano after an eruption occurs.

1. volcanic ash distributed by wind
2. a lahar formed from volcanic ash mixing with the quickly melted snow and ice
3. a pyroclastic flow of lapilli and super heated gases
4. a landslide caused by the collapse of coherent lava and friable ash deposits

Answer 1

Arranging the options in chronological order-

Option 3, option 2, option 1, option 4

Step-by-step explanation:

Stratovolcanoes are usually characterized by the highly elevated, cone-shaped volcano that produces the highly viscous lava, causing violent eruptions.

During the eruption of a stratovolcano, initially, the pyroclastic materials are ejected from the mouth of the volcano, which is transported to the distant places, along with the volcanic gases such as carbon dioxide, sulfur dioxide.

After this, a lahar is produced, which is commonly identified as a mudflow that eventually melts the snow and ice when comes in contact with each other.

The volcanic ashes that are produced from the eruption are carried by the prevailing wind and are transported to distant places.

Lastly, when the lava comes out, in association with the ash deposits, it flows downward along the slope of the volcano.

Thus, the volcanic hazards after a violent eruption, are arranged in the chronological order
