Natural Phenomena that Cause Disasters
  • Planet Earths heat flow and lithospheric
    interactions cause EARTHQUAKES

Iran has a long history of destructive
earthquakes, which have left at least 126,000
dead during the 20th and 21st centuries.
8
A DISASTER is ---
  • --- the set of failures that overwhelm the
    capability of a community to respond without
    external help  when three continuums 1)  people,
    2) community (i.e., a set of habitats,
    livelihoods, and social constructs), and 3)
    complex events (e.g., earthquakes, cyclones,..)
    intersect at a point in space and time.

9
Disasters are caused by single- or
multiple-event natural hazards that, (for
various reasons), cause extreme levels of
mortality, morbidity, homelessness, joblessness,
economic losses, or environmental impacts.
10
THE REASONS ARE . . .
  • The community is UN-PREPARED for what will likely
    happen

11
THE REASONS ARE . . .
  • When it does happen, the functions of the
    communitys buildings and infrastructure that are
    UNPROTECTED with the appropriate codes and
    standards will be LOST.

12
THE REASONS ARE . . .
  • The community has NO DISASTER PLANNING SCENARIO
    or WARNING SYSTEM in place as a strategic
    framework for concerted local, national,
    regional, and international actions.

13
THE REASONS ARE . . .
  • The community LACKS THE CAPACITY TO RESPOND to
    the full spectrum of emergency situations that
    can occur.

14
THE REASONS ARE . . .
  • The community is INEFFICIENT during recovery and
    reconstruction because it HAS NOT LEARNED from
    either the current experience or the cumulative
    prior experiences.

LESSONS LEARNED ABOUT DISASTER RESILIENCE
  • ALL EARTH-QUAKES PREPAREDNESS FOR THE LIKELY
    GROUND SHAKING IS ESSENTIAL FOR DISASTER
    RESILIENCE

WHAT WILL HAPPEN?EARTHQUAKE HAZARDS (AKA THE
POTENTIAL DISASTER AGENTS)
22
EARTHQUAKE HAZARDS MODEL
23
Iran has many well-known seismically active
faults, which have generated devastating
earthquakes in recent years, including a M6.6
earthquake in 2003 that destroyed the city of Bam
and killed more than 26,000 people

LESSONS LEARNED ABOUT DISASTER RESILIENCE
  • ALL EARTH-QUAKES BUILDING CODES AND
    LIFELINE STANDARDS ARE ESSENTIAL FOR DISASTER
    RESILIENCE

31
LESSONS LEARNED ABOUT DISASTER RESILIENCE
  • ALL EARTH-QUAKES TIMELY EMERGENCY RESPONSE IS
    ESSENTIAL FOR DISASTER RESILIENCE

SOME OF IRANS MANY NOTABLE EARTHQUAKES

  • M6.4 TABRIZ AUG. 11, 2012

IMPACTS
  • The Bam earthquake was particularly destructive,
    with 26,271 dead and 30,000 injured.

39
EXACERBATING FACTORS
  • Irans earthquake specialists knew that the mud
    bricks of the citadel, a historical cultural
    heritage, did NOT comply with earthquake
    regulations set in 1989, but the mud bricks, a
    fact of life, could not be adequately
    strengthened.
  • .

40
EXACERBATING FACTORS
  • The high morbidity and mortality tolls were
    exacerbated by the fragility of the mud brick
    construction materials.

41
INTERNATIONAL ASSISTANCEMany nations, including
the USA, offered assistance and resources.

TWIN MODERATE-MAGNITUDE EARTHQUAKES STRIKE
IRANSATURDAY, AUGUST 11, 2012

LOCATION MAP
44
THE EARTHQUAKES (Source US Geological Survey)
  • Saturday's first quake of M6.4 struck just before
    5 pm 60 km (37 miles) northeast of the city of
    Tabriz at a depth of 9.9 km (6.2 miles).
  • Saturdays second quake of M6.3 struck 49 km (30
    miles) northeast of Tabriz 11 minutes later at a
    similar depth.

45
The earthquakes struck in East Azerbaijan
province, a mountainous region that neighbors
Azerbaijan and Armenia to the north and is
predominantly populated by ethnic Azeris, a
minority group.
46
INITIAL IMPACTS
  • Over 1,000 villages were affected, with over
    5,000 buildings in 100 villages partially or
    totally destroyed as concrete-block and mud-brick
    buildings collapsed.
  • At least 20 villages could not be reached because
    of impassable roads.
  • People in some villages were in dire need of food
    and drinking water.

47
VARZAGHAN DAMAGE
48
VARZAGHAN DAMAGE
49
INITIAL IMPACTS
  • Over 300 dead (more likely), with over 60 percent
    being women and children, partly due to the time
    of day (5 PM) that the quake struck.
  • Over 1,800 injured.

50
INITIAL IMPACTS (continued)
  • 36,000 people in the quake-hit area were
    provided with emergency shelter.
  • Many slept on the street and in parks.
  • A field hospital set up in Varzaghan on Sunday to
    treat the injured was staffed by just two
    doctors, who, because of shortages of medical
    supplies and food, were hard pressed to meet the
    emergency medical needs.

51
INITIAL IMPACTS (continued)
  • Hospitals in Tabriz (49 km distance) took in many
    of the injured from the surrounding villages.
  • Water, electricity, and phone lines in the
    Varzaghan area were all down, further hindering
    rescue efforts
  • Preliminary loss estimate 650 million USD

52
VARZAGHAN INITIAL S R MOSTLY BY RESIDENTS AUG
11th
53
A CONTROVERSIAL DECISION
  • Search and rescue was stopped after 24 hours and
    a 2-day period of mourning started

54
THIS DISASTER EXPOSED POLICY FLAWS
  • UNPROTECTED
  • UNPREPARED
  • UN--ABLE TO RESPOND EFFECTIVELY

55
FACT VILLAGE HOUSES WITH LITTLE OF NO
EARTHQUAKE RESISTANCE COLLAPSED, INCREASINGING
DEATHS AND INJURIES
  • The 5 pm occurrence) instead of a 10 pm
    occurrence) likely reduced the number of deaths.

56
FACT KNOWING WHERE THE SEISMICALLY ACTIVE FAULTS
ARE AND BEING UNPREPARED FOR THE INEVITABLE
EARTHQUAKES LEADS TO UNNECESSAY DISASTERS
57
FACT EVEN THE WORLDS BEST FIRST RESPONDERS,
FIND THAT COLLAPSED BUILDINGS, IMPASSABLE
ROADS, AFTERSHOCKS, and NIGHTFALL WILL SLOW
SEARCH AND RESCUE OPERATIONS AND HINDER EMERGENCY
RESPONSE
58
IRANIAN RED CRESCENT WILLING TO ACCEPT
INTERNATIONAL AID
  • "We would welcome help by any country," said
    Iran's parliament speaker, Ali Larijani, during
    his visit to the earthquake-stricken area on
    Tuesday, August 14th.

59
RED CRESCENT ASSETS DEPLOYED
  • 1,100 Red Crescent workers were deployed with
    44,000 food packages and 5,600 tents for
    survivors needing temporary shelter.

60
IRANS NEXT EARTHQUAKE IS INEVITABLE
  • BUT, EARTHQUAKE DISASTER RESILIENCE IS NOT AN
    IMPOSSIBLE DREAM!
