DANGEROUS VOLCANOES IN THE WORLD A RE-ERUPTION OF 11 OF THE 1, 500 ACTIVE VOLCANOES IS LIKELY TO BE VERY DEVASTATING, LOCALLY, REGIONALLY, AND GLOBALLY Dr. Walter Hays, Global Alliance For Disaster Reduction
GLOBAL DISTRIBUTION OF 1, 500 ACTIVE VOLCANOES
11 VOLCANOES THE WORLD HOPES WILL NOT ERUPT AGAIN • Eyjafjallajökull and Katla (ICELAND) • Chaiten • Krakatau • Merapi • • • Vesuvius Pinatubo Mount Rainier Nevada del Ruiz Popocatepl Nyirangongo (CONGO)
WHAT MAKES A VOLCANO ESPECIALLY DANGEROUS • Location and a large explosivity index (VEI) combine to make some volcanoes especially dangerous.
LOCATION NEAR CITIES MAKES SOME VOLCANOES VERY DANGEROUS An eruption at some locations is certain to be devastating to people, their property, their health, the community infrastructure, the environment, and the economy.
The Eyjafjallajökull and Katla Volcanoes: Southern Iceland
EUROPEAN AIR TRAFFIC DISRUPTED: APRIL 15, 2010
The 800 -meter fissure caused by the first eruption, which grew to 1. 2 km in the second eruption, could be heading towards the Myrdalsjokall glacier, which sits atop the powerful Katla volcano
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, 00010, 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
Krakatau • 26 -27 August, 1883 • The big one! http: //www. geology. sdsu. edu/how_volcanoes_work/Krakatau. html

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

MT. PINATUBO: THE PHILIPPINES; JUNE 15, 1991
Pinatubo was the second largest eruption of the 20 th century and the largest to impact a densely populated area.
MOUNT RAINIER: THREAT TO WASHINGTON (USA)

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
Africa's most active volcano.
NYIRANGONGO: DEMOCRATIC REPUBLIC OF CONGO; A THREAT TO GOMA
ERUPTION OF NYIRANGONGO: JANUARY 2, 2010
WARNING: Don’t forget that the other 1490 active volcanoes can erupt anytime, also.
