LESSONS LEARNED FROM PAST NOTABLE DISASTERS THE CARIBBEAN PART 4: VOLCANIC ERUPTIONS Walter Hays, Global Alliance for Disaster Reduction, Vienna, Virginia, USA

Natural Phenomena that Cause Disasters Planet Earth’s heat flow and lithospheric- mantle collision- zone inter- actions cause VOLCANIC ERUPTIONS

NATURAL HAZARDS THAT HAVE CAUSED DISASTERS IN THE CARIBBEAN BASIN FLOODS WINDSTORMS EARTHQUAKES VOLCANIC ERUPTIONS ENVIRONMENTAL DEGRAD- ATION GLOBAL CLIMATE CHANGE HIGH BENEFIT/COST PROGRAMS FOR BECOMING DISASTER RESILIENT GOAL: PROTECT PEOPLE AND COMMUNITIES

GLOBAL DISTRIBUTION OF 1,500 ACTIVE VOLCANOES

ACTIVE VOLCANOES

THE CARIBBEAN BASIN

The Caribbean: long referred to as the West Indies, includes more than 7,000 islands; of these, 13 are independent island countries

ISLANDS POSSESSING MINOR VOLCANIC FEATURES Aruuba, Barbados, Bahamas, Bonaire, Cayman Islands, Saint Croix, and Antigua

ISLANDS POSSESSING RUGGED MOUNTAIN RANGES Cuba, Hispaniola, Puerto Rico, Jamaica,,Dominica, Montserrat, Saba, Saint Kitts, Saint Lucia, Saint Thomas, Saint John, Tortola, Grenada, Saint Vincent, Guadeloupe, Martinique, and Trinidad and Tobago

ELEMENTS OF RISK AND DISASTER

THE CARIBBEAN’S VOLCANOES The present dozen active volcanoes on or near the Caribbean are restricted to the Lesser Antilles

THE BEST KNOWN HISTORIC ERUPTIONS The best known are:oufriere on Guadeloupe, Mount Pelee on Martinique (well-known for its disastrous 1902 eruption and nuee ardente destroying St. Pierre and killing some 28,000 people), Kick'Em Jenny, a submarine volcano north of Grenada, and a series of eruptions beginning in 1995 on Montserrat.

THE VOLCANO HAZARDS ARE POTENTIAL DISASTER AGENTS

VOLCANO HAZARDS (AKA POTENTIAL DISASTER AGENTS) VERTICAL PLUME ASH AND TEPHRA LATERAL BLAST PYROCLASTIC FLOWS

VOLCANO HAZARDS (AKA POTENTIAL DISASTER AGENTS) LAVA FLOWS LAHARS EARTHQUAKES (related to movement of lava) “VOLCANIC WINTER”

A DISASTER CAN HAPPEN WHEN THE POTENTIAL DISASTER AGENTS OF A VOLCANIC ERUPTION INTERACT WITH A CARIBBEAN NATION’S COMMUNITIES

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., a volcanic eruption,...) intersect at a point in space and time.

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.

THE REASONS ARE... When it does happen, the functions of the community’s buildings and infrastructure will be LOST because they are UNPROTECTED with the appropriate codes and standards.

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.

EXAMPLES OF PAST VOLCANO DISASTERS MONTSERAT

SOUFRIERE HILLS: 1995 and following

SOUFRIERE HILLS ERUPTION

SOUFRIERE HILLS VOLCANO, MONTSERAT: 1995 TO PRESENT The capital, Plymouth, was buried by ash and eventually evacuated. 2,000-3,000 still remain on the island.

IMPACTS Numerous evacuations followed by temporary resumptions made normal life impossible. Plymouth, which was eventually destroyed, was unable to function effectively as the capital.

THE ALTERNATIVE TO A VOLCANO DISASTER IS VOLCANO DISASTER RESILIENCE
