UNDERSTANDING
EXPLOSIVE VOLCANOES
542 OF THE 1,500 ACTIVE VOLCANOES
ARE LOCATED IN “RING OF FIRE”
VOLCANOES IN INDONESIA
INDONESIA, A PART OF THE PACIFIC
“RING OF FIRE,” HAS 127 ACTIVE
VOLCANOES AS A RESULT OF COMPLEX
SUBDUCTION OF THE INDO-AUSTRALIA
AND EURASIA TECTONIC PLATES
INDONESIA’S VOLCANOES
PHYSICAL EFFECTS OF
EXPLOSIVE VOLCANIC ERUPTIONSA NATURAL HAZARD
VERTICAL ASH PLUME, HIGH-VELOCITY
LATERAL BLAST, TEPHRA, LAVA FLOWS,
LAHARS, AND VOLCANIC WINTER
VOLCANO HAZARDS
CAN HAVE FAR REACHING IMPACTS
• VERTICAL ASH PLUME (can
affect jet aircraft)
• ASH AND TEPHRA
• LATERAL BLAST
• PYROCLASTIC CLOUDS,
BURSTS, AND FLOWS
VOLCANO HAZARDS
CAN HAVE FAR REACHING IMPACTS
• LAVA FLOWS
• LAHARS (can bury villages)
• EARTHQUAKES (related to
movement of lava)
• “VOLCANIC WINTER” (causing
famine and mass extinctions)

BEFORE AUGUST, 2010,
SINABUNG HAD BEEN
INACTIVE FOR 400 YEARS
The August eruption led to an
evacuation of 30,000 people
MOUNT SINABUNG:
NOV. 3, 2013
SEPTEMBER 2013 ERUPTION
• An eruption in September 2013
also prompted an evacuation--about 3,500 villagers lining within
3 km of the volcano.
OCTOBER 2013 ERUPTION
• Another eruption on October
24th also prompted an
evacuation of about 3,500
villagers lining within 2-3 km of
the volcano.
WHAT HAPPENED
NOVEMBER 3RD
• The 8,530-foot-high mountain erupted
early on Sunday, November 3rd,
sending a vertical ash plume 7,000 feet
into the air.
• This eruption prompted an evacuation
of 1,500 people living within 3 km of the
volcano.

THE KEYS TO RESILIENCE:
1) KNOW THE ERUPTIVE HISTORY OF
YOUR REGION’S VOLCANOES,
2) BE PREPARED
3) HAVE A WARNING SYSTEM
4) EVACUATE
5) LEARN FROM THE
EXPERIENCE AND BE READY TO
START OVER
CREATING TURNING POINTS FOR
FLOOD DISASTER RESILIENCE
 USING EDUCATIONAL SURGES CONTAINING
THE PAST AND PRESENT LESSONS TO FOSTER
AND ACCELERATE THE CREATION OF TURNING
POINTS
2014--2020 IS A GOOD TIME
FOR A GLOBAL SURGE IN
EDUCATIONAL, TECHNICAL,
HEALTH CARE, AND POLITICAL
CAPACITY BUILDING
IN ALL FIVE PILLARS OF
COMMUNITY
DISASTER RESILIENCE
CREATING TURNING POINTS FOR
FLOOD DISASTER RESILIENCE
INTEGRATION OF SCIENTIFIC AND
TECHNICAL SOLUTIONS WITH POLITICAL
SOLUTIONS FOR POLICIES ON
PREPAREDNESS, PROTECTION, EARLY
WARNING, EMERGENCY RESPONSE, AND
RECOVERY
INTEGRATION OF TECHNICAL AND POLITICAL
CONSIDERATIONS
OPPORTUNITIES FOR TURNING POINTS: For Disaster Resilience on
local, regional, national, and global scales
