TYPHOON VONGFONG HITS JAPAN AND CYCLONE HUDHUD HITS INDIA October 12, 2014

description

TYPHOON VONGFONG: A HUGE STORM. On Oct 7, in just 24 hours, Vongfong intensified from a CAT 2 storm to one with, 155 mph wind speeds, and an estimated central pressure of 908 millibars. The typhoon toppled trees, flooded streets and cut power to more than 60,000 homes. 35 people were reported injured in Okinawa and Kyushu, where 150,000 people were evacuated. Fifteen years ago, more than 10,000 people were killed when a cyclone hit roughly the same area, which lacked significant evacuation capability. CONCLUSION: A MAJOR IMPROVEMENT IN EVACUATION Presentation courtesy of Dr. Walter Hays, Global Alliance for Disaster Reduction

SEVERE WINDSTORMS: HURRICANES

• In the Atlantic, Caribbean, Gulf of Mexico, and Eastern Pacific areas cyclonic tropical storms with well-formed central “eyes” and with wind speeds above 74 mph are referred to as HURRICANES.

1325 HURRICANES: DYNAMIC LABORATORIES FOR LEARNING

• EACH HURRICANE TEACHES IMPORTANT TECHNICAL AND POLITICAL LESSONS ABOUT DISASTER RESILIENCE.

SEVERE WINDSTORMS: TYPHOONS

• The exact same phenomenon in the Western Pacific Ocean region is called a TYPHOON.

TYPHOON VONGFONG: 2014’S 6TH SUPER TYPHOON

Page 16: Typhoon Vongfong hits Japan and Cyclone Hudhud hits India

VONGFONG: A HUGE STORM

• On Oct 7, in just 24 hours, Vongfong intensified from a CAT 2 storm to one with, 155 mph wind speeds, and an estimated central pressure of 908 millibars.

TYPHOON VONGFONG REACHED OKINAWA

• Vongfong, which reached Okinawa on Sunday afternoon, October 12th, is expected to reach Tokyo on Tuesday, but as a much weaker storm

TYPHOON VONGFONG: INITIAL REPORTS

• 35 people were reported injured in Okinawa and Kyushu, where 150,000 people were evacuated.

• The typhoon toppled trees, flooded streets and cut power to more than 60,000 homes.

CYCLONE HUDHUD ARRIVED: OCT. 12

Page 20: Typhoon Vongfong hits Japan and Cyclone Hudhud hits India

HURRICANE HUDHUD: OCTOBER 12

• Hudhud hit the southern port city of Visakhapatnam, location of a major naval base, close to noon.

• 400,000 people were evacuated earlier from the States of Odisha and Andhra Pradesh.

Page 21: Typhoon Vongfong hits Japan and Cyclone Hudhud hits India

HURRICANE HUDHUD: INITIAL REPORTS

• The States of Odisha and Andhra Pradesh experienced high winds and heavy rainfall.

• Six killed.• Power was disrupted and commun-

ications collapsed.

Page 22: Typhoon Vongfong hits Japan and Cyclone Hudhud hits India

CONCLUSION: A MAJOR IMPROVEMENT IN EVACUATION

• India’s Evacuation operations have improved significantly during the past 15 years, with a corresponding reduction in mortality.

Page 23: Typhoon Vongfong hits Japan and Cyclone Hudhud hits India

1999, 2013, AND 2014

• Fifteen years ago, more than 10,000 people were killed when a cyclone hit roughly the same area, which lacked significant evacuation capability.

• In October, 2013, Cyclone Phailin resulted in 800,000 being evacuated with few deaths.

• October 12, 2014; 400,000 evacuated with 6 deaths
