GLOBAL DISTRIBUTION OF 1,500 ACTIVE VOLCANOES

VOLCANIC ERUPTIONS are awesome manifestations of heat flowing as a result of mantle hot spots (e.g., Hawaii and Iceland) or explosive eruptions in subduction zones (e.g., the Pacific Rim).

ACTIVE VOLCANOES

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

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

WE CONTINUE TO OPERATE WITH A FLAWED PREMISE: KNOWLEDGE FROM DISASTERS RELATED TO EXPLOSIVE VOLCANIC ERUPTIONS IS ENOUGH TO MAKE ANY NATION WITH PEOPLE AND ASSETS AT RISK ADOPT AND IMPLEMENT POLICIES TO BECOME DISASTER RESILIENT

FACT: IT USUALLY TAKES MULTIPLE VOLCANIC ERUPTIONS BEFORE A STRICKEN NATION WILL ADOPT AND IMPLEMENT POLICIES THAT MOVE IT TOWARDS DISASTER RESILIENCE

FACT (continued) BUT, THE INTERVAL OF TIME BETWEEN EXPLOSIVE VOLCANIC ERUPTIONS CAN BE AS LONG AS 500 OR MORE YEARS.

FACT: MOST UNAFFECTED NATIONS DON’T EVEN TRY TO LEARN ANYTHING NEW FROM ANOTHER NATION’S VOLCANIC DISASTERS AND DON’T CONSIDER THEM TO BE A BASIS FOR CHANGING EXISTING POLICIES

ELEVEN OF THE WORLD’S NOST DANGEROUS VOLCANOES THE NEXT ERUPTION OF THESE 11 ACTIVE VOLCANOES IS LIKELY TO BE DEVASTATING LOCALLY, REGIONALLY, AND GLOBALLY

WHAT MAKES THESE 11 VOLCANOES DANGEROUS Eyjafjallajökull and Katla (ICELAND) Chaiten Krakatau Merapi Vesuvius Pinatubo Mount Rainier Nevada del Ruiz Popocatepl Nyirangongo (CONGO)

THEIR LOCATION NEAR CITIES AND INTERNATIONAL AIRLINE ROUTES An eruption of any one of these eleven volcanoes is certain to be devastating to people, their property, their health, the economy, and, sometimes, the regional air space.

Eruption of the Eyjafjallajökull Volcano in Southern Iceland A Threat to North American- European Air Traffic MARCH 20, 2010

The Eyjafjallajökull and Katla Volcanoes: Southern Iceland

The Eyjafjallajökull (AYA-feeyapla-yurkul) volcano in Southern Iceland, part of the volcanic process that originally formed Iceland, erupted a few minutes before midnight on Saturday, March 20th

EUROPEAN AIR TRAFFIC DISRUPTED: APRIL 15, 2010

An eruption of the Katla volcano, located under the massive Myrdalsjokull icecap, could cause disastrous local flooding, explosive blasts, and eruption clouds that would disrupt air traffic between Europe and the USA.

VOLCANO CHAITEN ERUPTS: CHILE: MAY 3, 2008

CHAITEN ERUPTED AFTER 8,000-10,000 YEAR DORMANCY THE 1,200 M (3,550 FT) VOLCANO SENT ASH HIGH INTO THE SKY. “VOLCANIC EARTHQUAKES WERE TRIGGERED IN THE AREA. 1,500 RESIDENTS EVACUATED, MOSTLY BY BOAT

MOUNT MERAPI: INDONESIA

INDONESIA’S MOUNT MERAPI ERUPTED ON MAY & JUNE, 2006 Mount Merapi emitted lava, debris, and a pyroclastic flow on May 15, but this one was not devastating.

EXPLOSIVENESS OF JUNE 8 ERUPTION SENT 15,000 FLEEING

MOUNT VESUVIUS: ITALY; a threat to naples

MOUNT FUJI: JAPAN; a threat to tokyo

Mt. PiNATUBO: THE PHILIPPINES; JUNE 15, 1991

Pinatubo was the second largest volcanic eruption of the 20th century and the largest to impact a densely populated area.

MOUNT RAINIER: threat to SEATTLE, WASHINGTON (USA)

MOUNT RAINIER: LAHAR SIMULATION

MOUNT RAINIER: LAHAR SIMULATION

MOUNT RAINIER: LAHAR SIMULATION

NEVADA DEL RUIZ: COLOMBIA; a 1988 disaster

The lahar generated by the eruption of Nevada del Ruiz buried 25,000 people in the city of Armero as they slept.

POPOCATEPL: MEXICO; a threat to mexico city

“POPO” AND MEXICO CITY

RUMBLINGS OF ERUPTION OF “POPO” ON JULY 4, 2013

Africa's most active volcano.

NYIRANGONGO: DEMOCRATIC REPUBLIC OF CONGO; A THREAT TO GOMA

ERUPTION OF NYIRANGONGO: JANUARY 2, 2010

WARNING: The other 1,489 active volcanoes can also have dangerous eruptions anytime.

ERUPTION OF PUYEHUE IN CHILE: FEB, 2012

ERUPTION OF CHAPARRASTIQUE IN EL SALVADOR: DEC., 2013

LESSON: THE KNOWLEDGE AND TIMING OF ANTICIPATORY ACTIONS IS VITAL The people who know: 1) what hazards to expect (e.g., vertical ash plume, lateral blast, lava flow, lahar), 2) where and when they will happen, and 3) what they should (and should not) do to prepare for them will survive.

LESSON: TIMELY, REALISTIC DISASTER SCENARIOS SAVE LIVES The people who have timely, realistic, advance information that facilitates reduction of vulnerabilities, and hence the risks associated with the vertical ash plume, pyroclastic flows, tephra, lava flows, and lahars will survive.

LESSON: TIMELY EARLY WARNING SAVES LIVES The people who have timely, accurate, advance information that facilitates evacuation to get our of harm’s way of pyroclastic flows, lava flows, and lahars will survive.

LESSON: EMERGENCY RESPONSE SAVES LIVES The timing of emergency response operations, especially the evacuations and the search and rescue operations (limited to “the golden 48 hours)” will save lives

LESSON: EMERGENCY MEDICAL PREPAREDNESS SAVES LIVES The local community’s capacity for emergency health care (i,e., coping with damaged hospitals and medical facilities, lack of clean drinking water, food, and medicine, and high levels of morbidity and mortality) is vital for survival.

LESSON: EARTHQUAKE ENGINEERED BUILDINGS SAVE LIVES Buildings engineered to withstand the risks from a vertical plume, ash, pyroclastic flows, and tephra that cause damage, collapse, and loss of function, is vital for protecting occupants from death and injury.

LESSON: THE INTERNATIONAL COMMUNITY ALWAYS PROVIDES AID The International Community provides millions to billions of dollars in relief to help “pick up the pieces, ” but this strategy is not enough by itself to ensure earthquake disaster resilience.
