- Slide 1
- LESSONS LEARNED FROM PAST NOTABLE DISASTERS CHILE PART 2: WINDSTORMS Walter Hays, Global Alliance for Disaster Reduction, Vienna, Virginia, USA
- Slide 2
- NATURAL HAZARDS THAT HAVE CAUSED DISASTERS IN CHILE FLOODS WINDSTORMS EARTHQUAKES/TSUNAMIS VOLCANOES WILDFIRES GLOBAL CLIMATE CHANGE HIGH BENEFIT/COST FROM BECOMING DISASTER NRESILIENT GOAL: PROTECT PEOPLE AND COMMUNITIES
- Slide 3
- Natural Phenomena that Cause Disasters Planet Earths atmospheric- hydrospheric- lithospheric interactions create SEVERE WINDSTORMS
- Slide 4
- HIGH POTENTIAL LOSS EXPOSURES IN A SEVERE WINDSTORM Entire communities; People, property, infra- structure, business enterprise, government centers, crops, wildlife, and natural resources.
- Slide 5
- FORTUNATELY, CHILES WINDSTORMS, ALTHOUGH DAMAGING, ARE USUALLY NOT CLASSIFIED AS SEVERE
- Slide 6
- NOTABLE WINDSTORMS IN CHILE JULY 22, 2011 (WHITE EARTHQUAKE) JULY 6, 2011 (DESERT STORM) JUNE 8, 2011 (TORNADO) JULY 29, 2000 (RAINSTORM)
- Slide 7
- Natural Phenomena that Cause Disasters Planet Earths atmospheric- hydrospheric- lithospheric interactions create WHITE EARTH- QUAKES
- Slide 8
- WHITE EARTHQUAKE HITS EIGHT MUNICIPALITIES Eight municipalities of Chile were isolated by a 'white earthquake' of heavy snow with drifts of up to 2 meters or more of snow (equal to the normal snowfall in a 4 month period). The government declared these municipalities a "disaster area."
- Slide 9
- THE WHITE EARTHQUAKE
- Slide 10
- CHILES CITIES (NOTE: ATACAMA DESERT IN NORTH)
- Slide 11
- JULY 6, 2011
- Slide 12
- The Atacama is the world's driest desert, where wetting rains are truly rare visitors.
- Slide 13
- JULY 6, 2011 A winter storm with unusual rain, high winds, and mountain snow struck the northern desert regions of Antofagasta and Atacama only days after another rare desert storm.
- Slide 14
- JULY 6, 2011 Roads were cut off and flights disrupted in an area that holds some of the world's biggest, most productive copper mines.
- Slide 15
- JUNE 8, 2011 WINDSTORM This windstorm was a tornado, a rare event for Chile. It struck the heart of the town of Villarrica in southern Chile with winds of 125 to 183 kph (75 to 110 mph).
- Slide 16
- Villarrica, a city and commune in southern Chile, is located on the western shore of Villarrica Lake near the active Villarrica volcano, 746 km (464 mi) south of Santiago, the capital.
- Slide 17
- Slide 18
- IMPACTS OF THE WINDSTORM Only damage and nine injuries this time.
- Slide 19
- SANTIAGO SKYLINE
- Slide 20
- This disaster exposed Chiles lack of disaster planning and disaster-resilient infrastructure in 2000, and led to concerted efforts to improve.
- Slide 21
- JULY 29, 2000 WINDS AND FLOODING IMPACT THE CAPITAL A state of emergency was declared in the Santiago metropolitan region.
- Slide 22
- IMPACTS Schools were forced to close, train services were cancelled and electricity was cut to many areas due to the high winds.
- Slide 23
- IMPACTS Many homes were wiped out as a result of the 90 kph (54 mph) winds and the pouring rains, forcing thousands into shelters around Santiago.
- Slide 24
- JULY 29, 2000 FLOODING IMPACTED THE CAPITAL Some areas of the city were at a virtual standstill as roads were blocked and bridges collapsed

- Slide 28
- A DISASTER CAN HAPPEN WHEN THE POTENTIAL DISASTER AGENTS OF A WINDSTORM INTERACT WITH CHILES COMMUNITIES

- Slide 30
- 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., windstorms, floods,) intersect at a point in space and time.
- Slide 31
- Disasters are caused by s ingle- or multiple-event natural hazards that, (for various reasons), cause extreme levels of mortality, morbidity, homelessness, joblessness, economic losses, or environmental impacts.
- Slide 32
- THE REASONS ARE... When it does happen, the functions of the communitys buildings and infrastructure can be LOST
- Slide 33
- 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.
- Slide 34
- 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.
- Slide 35
- 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.
- Slide 36
- 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.
- Slide 37
- THE ALTERNATIVE TO A WINDSTORM DISASTER IS WINDSTORM DISASTER RESILIENCE

- Slide 39
- TECHNOLOGIES FOR MONITORING, FORECASTING, WARNING, AND DISASTER SCENARIOS ARE VITAL FOR SURVIVAL
- Slide 40
- LESSONS LEARNED ABOUT DISASTER RESILIENCE ALL WIND- STORMS PREPAREDNES FOR THE EXPECTED AND UNEXPEDTED IS ESSENTIAL FOR DISASTER RESILIENCE
- Slide 41
- LESSONS LEARNED ABOUT DISASTER RESILIENCE ALL WIND- STORMS EARLY WARNING (THE ISS) AND EVACUATION ARE ESSENTIAL FOR DISASTER RESILIENCE
- Slide 42
- LESSONS LEARNED ABOUT DISASTER RESILIENCE ALL WIND- STORMS TIMELY EMERGENCY RESPONSE IS ESSENTIAL FOR DISASTER RESILIENCE
