VOLCANIC-RELATED HAZARDS

Which potential- related hazard involves fragments of solid rock or molten lava being ejected from a volcano during explosive eruptions?

• ash

• ballistic projectiles

• lahar

• lava flows

Which of the following impacts of volcanic hazards is caused by ash fall?

• It may cause poor or low visibility.

• Destroy anything on it's path by direct impact.

• Areas affected once solidified are also rendered useless.

• It may cause puncture, dent, melt, burn, and topple structures and systems like power and telecom masts.

3. Which volcanic hazard involves a fast-moving, dense mixture of volcanic materials and water?

• ash

• lahar

• lava flows

• pyroclastic flows

Which volcanic hazard occurs when lava is degassed and/or highly viscous, causing it to extrude very slowly and form lava domes?

• lahar

• lava flows

• pyroclastic flows

• volcanic gases

Statement 1. Increase in volume of stream emission is a sign of impending volcanic eruption.

 Statement 2. Ground Shaking is a sign of volcanic eruption and a possible-related hazard of an earthquake.

• Both statement are correct

• Both statement are incorrect

• Statement 1 is correct while statement 2 is incorrect

• Statement 1 is incorrect while statement 2 is correct
