Study Notes

Natural Hazards and Disasters

  • Natural hazards and disasters cause significant property damage, injury, and death. Economic losses are often substantial and unpredictable.
  • The 1995 Kobe Japan earthquake illustrates the devastating impact, with over 5,000 fatalities, thousands of destroyed buildings, and over $100 billion in damage (1995 prices).
  • Canadian examples of hazards & disasters are used for context and analysis. Survivor/witness accounts and scientific expertise are employed.
  • 2024 examples of extreme weather include: Kerala landslides, Japan earthquake, Hurricanes Helene & Milton, Super Typhoon Yagi, Columbia droughts, India heat waves, Chile wildfires, and Brazil floods.

Kerala Landslides

  • Kerala, a state in southwest India, has some areas below sea level. Severe landslides struck hilly areas on July 30, 2024, ranking as one of the worst disasters in recent memory.
  • Over 200 deaths and hundreds more were buried, necessitating extensive army rescue efforts.

Japan Earthquake

  • Japan's Noto Peninsula experienced a 7.7 magnitude earthquake on January 1, 2024.
  • The disaster resulted in 504 deaths, over 1,300 injuries from the main shock, and 178,270 damaged structures. These events highlight earthquake preparedness issues.

Hurricanes Helene and Milton

  • Hurricane Helene, a Category 4 hurricane, hit Florida, Cuba, and Mexico in September 2024. 232 people were killed and damage exceeded $22 billion.
  • Hurricane Milton, initially a Category 5 hurricane that weakened to a Category 3, struck the west coast of Florida in late October 2024. High winds and rain caused significant damage. 32 deaths occurred in the US and 3 in Mexico.

Super Typhoon Yagi

  • Super Typhoon Yagi, one of the most powerful storms in Southeast Asia and China's history, affected the Philippines, Hong Kong, China, Vietnam, and Macau.
  • It resulted in 844 deaths, 2,279 injuries, and damage exceeding $16.9 billion.
  • The typhoon caused numerous landslides.

Columbia Droughts

  • Severe drought and record-breaking heat affected the Amazon River basin in Columbia from mid-2023 onwards.
  • Colombia's reliance on hydroelectricity (66%) forced a shift towards fossil fuels (up to 40%) due to extremely low reservoir water levels (53% capacity).

India Heat Waves

  • India experienced a record-breaking heat wave in 93% of days (255/274) starting in May 2024.
  • The extreme heat led to over 3,200 deaths in the first 9 months of 2024.

Chile Wildfires

  • Massive wildfires in central Chile in February 2024, worsened by El Niño and dry weather, killed over 130 people.

Brazil Floods

  • Heavy rains at the end of April 2024 caused record floods in Rio Grande do Sul, Brazil.
  • Over 180 people died, ~500,000 were displaced, and over 77,000 sought refuge in public shelters.

Canadian Natural Hazards

  • Canada faces various natural hazards, including earthquakes, icebergs, sea ice, fog, tsunamis, storm surges, floods, landslides, snow avalanches, volcanic eruptions, hail, tornadoes, and winter storms.

Annual Costs to Canada

  • Canadian Disaster Financial Assistance Arrangements (DFAA) spent $486 million (2016-17), $495 million (2017-18), and $310 million (2018-19) to assist after fires, floods, ice storms, and similar disasters.
  • Severe weather alone cost $1.3 billion in insured damages in 2019-2020.
  • Climate-related incidents have doubled in cost over the last decade.

Top Expensive Canadian Disasters

  • Major natural disasters (by insured costs) include the Fort McMurray wildfires (2016), Eastern ice storm (1998), Southern Alberta floods (2013), and Alberta hailstorm (2020).
  • Other significant events include the Toronto flood (2013, 2005), Ontario-Quebec thunderstorm (2022), Ontario windstorm (2018), British Columbia flood (2021), and Hurricane Fiona (2022).

DFAA Problems

  • Canada lacks a comprehensive study on the economic impacts of natural disasters.
  • The DFAA program, established in 1970, needs a review.
  • Coordination with provinces and territories is crucial for program implementation and maintenance.
  • The incidence and severity of natural disasters have increased despite tripling the thresholds in 2015.

DFAA Equity Issues

  • Horizontal equity: Disaster compensation disparities exist between lower-risk and higher-risk areas; provincial claim sizes differ.
  • Vertical equity: The program's exclusion of luxury assets and payout caps in most provinces target lower-income property owners. Delays in payments disproportionately impact low-income owners.
  • Flood coverage should be mandatory in home insurance, with subsidies in high-risk areas. Mandatory buyouts in the highest-risk areas are recommended.
  • The DFAA process involves a cyclical system of requests, approvals, payments and audits, with timelines for each step..
