SOME OF THE 1,500 ACTIVE
VOLCANOES ARE IN MEXICO
Natural Phenomena That Cause
Disasters
Planet Earth’s heat
flow causes
movement of
lithospheric
plates, which
causes sub-
duction, which
causes VOLCANIC
ERUPTIONS

―POPO’s ERUPTION HISTORY
• In the past centuries before
European came to Mexico,
large eruptions produced giant
mud flows that buried Aztec
settlements, and even entire
pyramids
―POPO’s ERUPTION HISTORY
• After almost 50 years of
dormancy, "Popo" came back
to life in 1994 and has been
producing powerful explosions
at irregular intervals since then.
VOLCANO HAZARDS
CAN HAVE FAR REACHING IMPACTS
• VERTICAL PLUME (can affect
jet aircraft)
• ASH AND TEPHRA
• LATERAL BLAST
• PYROCLASTIC CLOUDS,
BURSTS, AND FLOWS

VOLCANO HAZARDS
CAN HAVE FAR REACHING IMPACTS
• LAVA FLOWS
• LAHARS (can bury villages)
• EARTHQUAKES (related to
movement of lava)
• ―VOLCANIC WINTER‖ (causing
famine and mass extinctions)
A DISASTER CAN HAPPEN

OF RISK
CASE HISTORIES
LIKELY IMPACTS BASED ON
―POPO’s ERUPTION HISTORY
• The pyroclastic mud flows can
firm up like concrete once they
stop, ruining farmland and,
because they are difficult to
remove, disrupting life in
communities.
LIKELY IMPACTS
• Ash can be especially harmful and even
deadly to people who are unable to
evacuate.
• Ash can also be deadly to livestock, on
which the resident’s livelihood may
depend.
LIKELY ECONOMIC IMPACTS
• Air traffic may disrupt the economy for
long periods if the ash clouds intersect
the routes of jet aircraft and are a
threat to safety.
LIKELY ECONOMIC IMPACTS
• A new major eruption of Popocatepetl
would likely have a devastating
economic impact on local residents
who may be subsistence farmers and
some of the poorest of the poor.
• Ash would be especially deadly to
people and livestock (on which
livelihoods depend), and a potential
disaster for jet aircraft.
IMAGES OF
COLIMA
Colima is not one, but two different
volcanoes, the oldest one called Nevado
de Colima, that is located about 450 km
(270 mi) west of Mexico City
COLIMA
COLIMA
• The Volcán de Colima, also known as
Volcán de Fuego, is part of the Colima
volcanic complex consisting of Volcán
de Colima and Nevado de Colima.
• The youngest of the two, it is currently
one of the most active volcanoes in
Mexico and North America, erupting
more than 40 times since 1576
THE ALTERNATIVE TO A
VOLCANIC--ERUPTION
DISASTER IS
VOLCANO DISASTER
RESILIENCE
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., VOLCANIC ERUPTIONS,…)
intersect at a point in space and time.
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.
THE REASONS ARE . . .
• When it does happen, the
functions of the community’s
buildings and infrastructure can be
LOST for long periods.
THE REASONS ARE . . .
• The community is UN-
PREPARED for what will likely
happen, not to mention the
low-probability of occurrence—
high-probability of adverse
consequences event.
THE REASONS ARE . . .
• The community has NO DISASTER
PLANNING SCENARIO or
WARNING SYSTEM in place as a
strategic framework for early threat
identification and coordinated
local, national, regional, and
international countermeasures.
THE REASONS ARE . . .
• The community LACKS THE
CAPACITY TO RESPOND in a
timely and effective manner to
the full spectrum of expected
and unexpected emergency
situations.
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.

• Volcanic
ash ruins
crops and
vegetation
and disrupts
aviation.
LESSONS LEARNED ABOUT
DISASTER RESILIENCE
• Although a
complex
activity, timely
evacuation is
essential for
volcano dis-

Volcano erupts near mexico city threatens millions

  • 2. LESSONS LEARNED FROM PAST NOTABLE DISASTERS MEXICO PART 4: VOLCANIC ERUPTIONS
  • 3. USA – MEXICO FLIGHTS CANCELLED TEMPORARILY CONCERN ABOUT AIR SAFETY FROM THE ASH
  • 5. NATURAL HAZARDS THAT HAVE CAUSED DISASTERS IN MEXICO FLOODS SEVERE WINDSTORMS EARTHQUAKES VOLCANIC ERUPTIONS ENVIRONMENTAL CHANGE GLOBAL CLIMATE CHANGE DERIVHIGH BENEFIT/COST BY BECOMING DISASTER RESILIENT GOAL: PROTECT PEOPLE AND COMMUNITIES
  • 6. SOME OF THE 1,500 ACTIVE VOLCANOES ARE IN MEXICO
  • 7. Natural Phenomena That Cause Disasters Planet Earth’s heat flow causes movement of lithospheric plates, which causes sub- duction, which causes VOLCANIC ERUPTIONS
  • 8. VOLCANOES PART OF THE PACIFIC ―RING OF FIRE,‖ MEXICO HAS ACTIVE VOLCANOES AS A RESULT OF COMPLEX SUBDUCTION OF THE COCOS PLATE BENEATH THE NORTH AMERICAN PLATE
  • 9. MEXICO: THE NORTH AMERICAN AND COCOS PLATES
  • 11. IMAGES OF POPOCATEPTL MEXICO’S BEST KNOWN ACTIVE VOLCANO AND THE SECOND HIGHEST VOLCANO IN NORTH AMERICA ERUPTED AS RECENTLY AS APRIL 17, 2013
  • 13. ―POPO’s ERUPTION HISTORY • In the past centuries before European came to Mexico, large eruptions produced giant mud flows that buried Aztec settlements, and even entire pyramids
  • 14. ―POPO’s ERUPTION HISTORY • After almost 50 years of dormancy, "Popo" came back to life in 1994 and has been producing powerful explosions at irregular intervals since then.
  • 15. VOLCANO HAZARDS CAN HAVE FAR REACHING IMPACTS • VERTICAL PLUME (can affect jet aircraft) • ASH AND TEPHRA • LATERAL BLAST • PYROCLASTIC CLOUDS, BURSTS, AND FLOWS
  • 18. VOLCANO HAZARDS CAN HAVE FAR REACHING IMPACTS • LAVA FLOWS • LAHARS (can bury villages) • EARTHQUAKES (related to movement of lava) • ―VOLCANIC WINTER‖ (causing famine and mass extinctions)
  • 19. A DISASTER CAN HAPPEN WHEN THE POTENTIAL DISASTER AGENTS OF A VOLCANIC ERUPTION INTERACT WITH MEXICO’S COMMUNITIES
  • 20. AN ERUPTION OF POPOCATEPETL (AKA ―POPO‖) WOULD IMPACT NEARBY MEXICO CITY AND PUEBLA LOCATED 50 KM AWAY, 20 MILLION PEOIPLE ARE AT RISK
  • 21. MEXICO CITY, ―POPO‖ AND AN AIRPLANE
  • 23. LATERAL BLAST VOLCANIC ERUPTIONS PYROCLASTIC FLOWS FLYING DEBRIS VOLCANIC ASH LAVA FLOWS LAHARS TOXIC GASES CAUSES OF RISK CASE HISTORIES
  • 24. LIKELY IMPACTS BASED ON ―POPO’s ERUPTION HISTORY • The pyroclastic mud flows can firm up like concrete once they stop, ruining farmland and, because they are difficult to remove, disrupting life in communities.
  • 25. LIKELY IMPACTS • Ash can be especially harmful and even deadly to people who are unable to evacuate. • Ash can also be deadly to livestock, on which the resident’s livelihood may depend.
  • 26. LIKELY ECONOMIC IMPACTS • Air traffic may disrupt the economy for long periods if the ash clouds intersect the routes of jet aircraft and are a threat to safety.
  • 27. LIKELY ECONOMIC IMPACTS • A new major eruption of Popocatepetl would likely have a devastating economic impact on local residents who may be subsistence farmers and some of the poorest of the poor. • Ash would be especially deadly to people and livestock (on which livelihoods depend), and a potential disaster for jet aircraft.
  • 28. IMAGES OF COLIMA Colima is not one, but two different volcanoes, the oldest one called Nevado de Colima, that is located about 450 km (270 mi) west of Mexico City
  • 30. COLIMA • The Volcán de Colima, also known as Volcán de Fuego, is part of the Colima volcanic complex consisting of Volcán de Colima and Nevado de Colima. • The youngest of the two, it is currently one of the most active volcanoes in Mexico and North America, erupting more than 40 times since 1576
  • 31. THE ALTERNATIVE TO A VOLCANIC--ERUPTION DISASTER IS VOLCANO DISASTER RESILIENCE
  • 32. 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., VOLCANIC ERUPTIONS,…) intersect at a point in space and time.
  • 33. 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.
  • 34. THE REASONS ARE . . . • When it does happen, the functions of the community’s buildings and infrastructure can be LOST for long periods.
  • 35. THE REASONS ARE . . . • The community is UN- PREPARED for what will likely happen, not to mention the low-probability of occurrence— high-probability of adverse consequences event.
  • 36. THE REASONS ARE . . . • The community has NO DISASTER PLANNING SCENARIO or WARNING SYSTEM in place as a strategic framework for early threat identification and coordinated local, national, regional, and international countermeasures.
  • 37. THE REASONS ARE . . . • The community LACKS THE CAPACITY TO RESPOND in a timely and effective manner to the full spectrum of expected and unexpected emergency situations.
  • 38. 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.
  • 39. MEXICO’S COMMUNITIES DATA BASES AND INFORMATION HAZARDS: GROUND SHAKING GROUND FAILURE SURFACE FAULTING TECTONIC DEFORMATION TSUNAMI RUN UP AFTERSHOCKS •WINDSTORM HAZARDS •PEOPLE & BLDGS. •VULNERABILITY •LOCATION VOLCANO RISK RISK ACCEPTABLE RISK UNACCEPTABLE RISK GOAL: VOLCANO DISASTER RESILIENCE • PREPAREDNESS •PROTECTION •EARLY WARNING •EMERGENCY RESPONSE •RECOVERY and RECONSTRUCTION POLICY OPTIONS
  • 40. LESSONS LEARNED ABOUT DISASTER RESILIENCE • School children and adults need masks to counter adverse health effects of breathing volcanic ash.
  • 41. LESSONS LEARNED ABOUT DISASTER RESILIENCE • Volcanic ash ruins crops and vegetation and disrupts aviation.
  • 42. LESSONS LEARNED ABOUT DISASTER RESILIENCE • Although a complex activity, timely evacuation is essential for volcano dis- aster resilience
  • 43. AIR AND LAND MONITORING TECHNOLOGIES ARE VITAL .
  • 44. LESSONS LEARNED ABOUT DISASTER RESILIENCE ALL VOLCANIC ERUPTIONS ―RESTORATION TO NORMAL‖ AND RECOVERY USUALLY TAKE LONGER THAN THOUGHT.
