  • Tectonic Hazards Case Studies
    • Haiti 12th Jan 2010 (LIC)
      • Port-au-Prince
        • 7.0 on Richter Scale
        • Caribbean and Gonave plates (conservative)
        • 13km focus = shallow
        • Lasted for 1 minute
      • Impacts
        • 1.5 million homeless
        • $10 bn damage
        • small tsunami killed 7
        • 1 year on cholera outbreak and 1.5 million still homeless
        • 692,000 in make shift camps
      • Management- Long term   (3 P's)
        • Use light weight building materials
        • possible 9.0 EQ in next 20 years
        • Demolish slums
        • Urban Zonning
        • USGS monitor area
      • Management- Short term
        • 16,000 UN troops sent
        • $11.5 bn aid
    • Chances Peak LIC July 1995
      • Montserrat, Caribbean
        • Pélean- pyroclastic flow!
        • 5 million cubic meters of hot roak and gases down Soufiére Hills
        • Fires
        • Part of an island arc
        • Sea island cotton
      • Impacts
        • Farmland and vegetation lost
        • 19 dead
        • 3/4 infrastructure lost
        • over 6,500 evacuated to Antigua, USA & UK
        • 2/3 houses buried or destroyed
      • Management- Short term
        • £17 million UK aid for temporary buildings and water purification systems
        • Montserrat volcano observatory set up in 1995 and successfully predicted 1997 eruption
        • NGO's set up temporary schools e.g. Red Cross
        • Warning systems set up
        • US and UK Navy aided evac process
      • Management- Long term    (3 P's)
        • 3 yr re-development program  funded by UK
        • Vegetation   re-growing
        • Zoning- building away from volcano
        • South of Island still an exclusion zone
        • Volcano is a toursit attrection for geotourists
    • Mt Etna HIC  2002
      • Sicily, Italy
        • Agriculture
        • Stratovolcano (composite) several large secondary cones
        • Lava flows into Piano Provenzana = destroying structures
        • strombolian at summit, Fissure on the flanks
        • December intense Pyroclastic flows and ash fall ceased until jan eruption
        • October- strong EQ's felt
      • Impacts
        • Lava flow = damaged structures e.g. Rifugio Sapienza water tank exploded and hurt 30 people
        • no towns damaged
        • Air travel ban = stranded tourists
        • 100 houses damaged in Santa Venerina
        • EQ 6 on richter scale damaged buildings and  infrastructure
      • Management- Short term
        • Earth dams built
        • explosives used to divert lava
        • Network of tubes to divert lava away
        • Italian army brought in earth moving equipment
      • Management- Long term (3P's)
        • INGV monitors volcanos around the clock (gases, groundwater CO2  in soil
        • SO2 monitored closely
        • monitor seismic events, infra red, tiltmeter & remote sensing
        • Governement gave financial aid to those affected
        • data recorded and analysed
