29
Q

What are two methods for managing typhoons/cyclones/hurricanes?

A
  • Early warning systems
  • Evacuation plans
30
Q

What is flooding?

A

Overflow of water onto normally dry land due to heavy rain, storm surges, or rapid melting of snow.

31
Q

What are the impacts of flooding?

A

Destruction of property, agriculture, infrastructure, and displacement of people.

32
Q

What are two methods for managing flooding?

A
  • Flood barriers
  • Urban planning
33
Q

What is a drought?

A

Extended periods of below-average rainfall leading to water shortages.

34
Q

What are the impacts of drought?

A

Crop failure, water scarcity, and economic losses in agriculture.

35
Q

What are two methods for managing drought?

A
  • Water conservation measures
  • Efficient irrigation systems
36
Q

What is a heatwave?

A

Extended periods of abnormally high temperatures.

46
Q

What is a disaster?

A

A catastrophic event that causes significant damage, disruption, and loss of life, property, and resources.

Disasters can include natural events like earthquakes or human-made events such as industrial accidents.

47
Q

Define disaster risk.

A

The potential for a disaster to occur, based on the likelihood of hazards and the vulnerability of people, property, and systems.

Disaster risk assessment involves evaluating both the hazards and the exposure of different entities.

48
Q

What is a fast-moving, hot mixture of gas, ash, and volcanic debris that flows down the volcano’s slopes?

A

Pyroclastic Flow

Pyroclastic flows are among the most dangerous volcanic hazards due to their speed and temperature.

49
Q

What term describes volcanic ash and tephra ejected into the atmosphere that falls back to the ground over a wide area?

A

Ash Fall

Ash fall can cover large areas and affect air quality, agriculture, and water supplies.

50
Q

What is molten rock that moves down the volcano’s slopes, typically slow but capable of destroying property?

A

Lava Flows

Lava flows can vary in speed and composition, affecting their destructive potential.

51
Q

What gases, such as sulfur dioxide and carbon dioxide, are released during an eruption and can impact air quality and health?

A

Volcanic Gas Emissions

These gases can lead to acid rain and contribute to climate change.

52
Q

What is a volcanic mudflow or debris flow formed when volcanic ash mixes with water, often after heavy rainfall?

A

Lahar

Lahars can travel at high speeds and are particularly dangerous for communities near volcanoes.

53
Q

What large waves are generated by underwater volcanic eruptions or landslides, affecting coastal areas?

A

Tsunamis

Tsunamis can cause significant destruction and loss of life in coastal regions.

54
Q

What are solid fragments of rock ejected during an eruption, with bombs being larger than lapilli?

A

Volcanic Bombs and Lapilli

These fragments can vary in size and can be hazardous to people and structures near the eruption site.
