NATURAL HAZARDS THAT HAVE CAUSED DISASTERS IN ITALY FLOODS GOAL: PROTECT PEOPLE AND COMMUNITIES WINDSTORMS EARTHQUAKES HIGH BENEFIT/COST PROGRAMS FOR BECOMING DISASTER RESILIENT VOLCANOES ENVIRONMENTAL CHANGE GLOBAL CLIMATE CHANGE
A DISASTER is --- --- the set of failures that overwhelm the capability of a community torespond 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.
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 . . . • The community is UN-PREPARED for what will likely happen
THE REASONS ARE . . . • When it does happen, the functions of the community’s buildings and infrastructure that are UNPROTECTED with the appropriate codes and standards will be LOST.
THE REASONS ARE . . . • The community has NODISASTER PLANNING SCENARIO or WARNING SYSTEM in place as a strategic framework for concerted local, national, regional, and international actions.
THE REASONS ARE . . . • The community LACKS THE CAPACITY TO RESPOND 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.

SOME OF ITALY’S MANY NOTABLE EARTHQUAKES M6.9 IRPINIA: NOVEMBER 23, 1980 M6.3 L’AQUILA: APRIL 6, 2009
L’AQUILA EARTHQUAKEA Town of 70,000 M6.3 3:30 AM APRIL 6, 2009
SOCIOECONOMIC IMPACTS VULNERABLE UNREINFORCED MASONRY BUILDINGS DAMAGED UNIVERSITY DORM COLLAPSES VULNERABLE INFRASTRUCTURE DAMAGED AT LEAST 200 DEAD AND 2,000 NJURED TENS OF THOUSANDS HOMELESS
LACK OF HOSPITAL RESOURCES Many earthquake survivors had to be transported to Rome for surgery and/or treatment due to shortage of resources in the L’Aquila area
CONTROVERSY OVER CLAIM OF PREDICTION An Italian scientist claims to have predicted the earthquake on the basis of radon gas emissions from the fault zone. The Italian Government did not take any action because the technique is controversial.
THIS DISASTER EXPOSED POLICY FLAWS • UN—PROTECTED • UN—PREPARED • UN--ABLE TO RESPOND EFFECTIVELY
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.
FACT: KNOWING WHERE THE SEISMICALLY ACTIVE FAULTS ARE AND BEING UNPREPARED FOR THE INEVITABLE EARTHQUAKES LEADS TO UNNECESSAY DISASTERS
