“The Galveston Disaster”

Main Idea: The Galveston Disaster, the greatest natural disaster to strike the United States, was caused by the combination of many factors..

Introduction

- Galveston Disaster was greatest natural disaster to strike the United States

 8 Sept. 1900

 Combination of three factors:

High Wind

Great Waves

Storm Surge

 8,000 people dead

 More deaths than four natural disasters combined:

Johnstown Flood

San Francisco Earthquake

1938 New England Hurricane

Great Chicago Fire

- “In 1900 Galveston, home to about 37,000 people, was one of the most important cotton markets in America.”

- Island city located eastern end of Texas

- Low sand barrier

 48 km. (30 miles) long

 3.2 km. (2 miles) wide

 Highest point = 2.7 meters (8.7 feet) above sea level

- No modern technology to warn of possible disaster

 No geosynchronous satellites

 No Ship-to-shore radio

 No “networks of weather forecasters”

- Forecasting done by “experience and hunch.”

- Dr. Isaac Cline, Chief of U.S. Weather Bureau’s Galveston station considered “the best.”

The Strom Arrives

- On eve of 7 Sept, Cline becomes concerned. “Something was amiss.”

 26-kilometer (16-mile) per-hour winds.

 Wind coming from “wrong direction.”

 “High clouds were moving at sunset were moving in nearly the opposite way, from the southeast.”

 By midnight, wind shifted NE and grew to 60 kph (50 mph)

- At first people were curious as large waves came to shore and “water began to rise.”

- Cline sense a hurricane was imminent and “spread emergency warning.”

- As warning went out, a steamship was “torn from moorings and smashed […] three bridges connecting island to mainland.”

 Important factor = “There would be no escape.”

- The storm grew worse

 “Atmospheric pressure plummeted.”

 “Wind speed increased.”

 “Tropical cyclone’s low pressure drew the ocean into a broad mound and winds drove this mound ashore.”

 AKA “storm surge.”

- Surge arrived during high tide

- “Waters from Gulf of Mexico and Galveston Bay rose to meet each other.”

- People rushed into a buildings as high as 4 stories to escape water.

- Winds would reach 200 kph (125 mph)

 “collapse structures”

 Free “masses of flotsam that hammer anyone outside.”

- Afternoon, 8 Sept

 Buildings collapse

 “People battered by debris and drowned.”

- 20:30, Sept 8

 Water = 3.4 meter s (11 feet) above island’s highest point

- People die by thousands (redundant?) Much property lost

Galveston Rebuilds

- Galveston rebuilt in 1902

- Residents construct massive seawall

 5 meters (16-feet) thick

 5.2 meters (17 feet) high

 3 miles long

- Wall today is 10 miles long

- Town dredged enough sediment from Galveston bay to raise town 2.5 meters (8 feet)

- “Between 80% – 90% of the residents of hurricane-prone areas have not experienced a major hurricane.
