7Iran has a long history of destructive
earthquakes, which have left at least 126,000
dead during the 20th and 21st centuries.
8A 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.
9Disasters 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.
10THE REASONS ARE . . .
- The community is UN-PREPARED for what will likely
happen
11THE 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.
12THE 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.
13THE REASONS ARE . . .
- The community LACKS THE CAPACITY TO RESPOND to
the full spectrum of emergency situations that
can occur.
14THE 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.

POTENTIAL DISASTER AGENTS)
22 EARTHQUAKE HAZARDS MODEL
23Iran 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

35CITADEL OF BAM, IRAN BEFORE M6.6 EARTHQUAKE
36CITADEL OF BAM, IRAN AFTER EARTHQUAKE
37CITADEL OF BAM, IRAN AFTER EARTHQUAKE
38IMPACTS
- The Bam earthquake was particularly destructive,
with 26,271 dead and 30,000 injured.
39EXACERBATING 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. - .
40EXACERBATING FACTORS
- The high morbidity and mortality tolls were
exacerbated by the fragility of the mud brick
construction materials.
41INTERNATIONAL ASSISTANCEMany nations, including
the USA, offered assistance and resources.
42TWIN MODERATE-MAGNITUDE EARTHQUAKES STRIKE
IRANSATURDAY, AUGUST 11, 2012
43LOCATION MAP
44THE 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.
45The 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.
46INITIAL 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.
47VARZAGHAN DAMAGE
48VARZAGHAN DAMAGE
49INITIAL 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.
50INITIAL 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.
51INITIAL 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
52VARZAGHAN INITIAL S R MOSTLY BY RESIDENTS AUG
11th
53A CONTROVERSIAL DECISION
- Search and rescue was stopped after 24 hours and
a 2-day period of mourning started
54THIS DISASTER EXPOSED POLICY FLAWS
- UNPROTECTED
- UNPREPARED
- UN--ABLE TO RESPOND EFFECTIVELY
55FACT 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.
56FACT KNOWING WHERE THE SEISMICALLY ACTIVE FAULTS
ARE AND BEING UNPREPARED FOR THE INEVITABLE
EARTHQUAKES LEADS TO UNNECESSAY DISASTERS
57FACT 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
58IRANIAN 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.
59RED CRESCENT ASSETS DEPLOYED
- 1,100 Red Crescent workers were deployed with
44,000 food packages and 5,600 tents for
survivors needing temporary shelter.

- BUT, EARTHQUAKE DISASTER RESILIENCE IS NOT AN
IMPOSSIBLE DREAM!
