Question

Lava Flows of 1973 (cont): But the volume of lava was not overwhelming, so the Icelanders took over. Pyroclastic material was bulldozed to create barriers that diverted and controlled the flow of later lavas and even controlled the flow paths of the dense volcanic gases.

A) The material was left untouched
B) Efforts were made to control the flows
C) Barriers worsened the situation
D) No response from the locals

Answer 1

In the 1973 lava flows in Iceland, locals created barriers using pyroclastic material to successfully divert and control the lava and gases, which is an example of effective disaster management.

Step-by-step explanation:

The efforts made to control the lava flows in Iceland in 1973 involved the use of pyroclastic material to create barriers. These barriers were effective in diverting and controlling the flow of later lavas and also helped to control the flow paths of the dense volcanic gases. Unlike leaving the material untouched or exacerbating the situation, the local response demonstrated proactive disaster management. Historical examples of volcanic activity, such as the eruption of Mount Vesuvius and Mount St. Helens, show the devastating impact when such measures are not taken, with loss of life and transformation of landscapes.
