Galveston Hurricane of 1900: Deadliest Disaster in US History

The Galveston hurricane of 1900 is the deadliest natural disaster in the history of the United States. On the night of 8 September 1900 a powerful hurricane drove a storm surge across Galveston Island, Texas, destroying much of the city and killing an estimated 6,000 to 12,000 people. Galveston’s response, a massive seawall and the raising of the entire city, became a landmark in coastal engineering.

Background: the “Wall Street of the Southwest”

At the turn of the century Galveston was one of the richest and busiest cities in Texas. Its deep-water port shipped cotton to the world, and its banks and merchants earned it the nickname “Wall Street of the Southwest”. In 1900 the city had about 37,000 residents.

Galveston sat on a low barrier island in the Gulf of Mexico, about 30 miles long and only a few miles wide. Its highest point was less than 9 feet above sea level. After a hurricane destroyed the nearby port of Indianola in 1886, some had proposed a seawall, but the idea was rejected as unnecessary and expensive. Many residents believed the gently sloping sea floor would protect the island from large waves.

Forecasting the storm

The storm was first noted in the Caribbean in late August and crossed Cuba as a tropical storm in early September. Cuban meteorologists, with long experience of hurricanes, believed it would move into the Gulf of Mexico. The US Weather Bureau, led by Willis L. Moore, had restricted Cuban weather reports and expected the storm to curve north toward Florida and the Atlantic coast.

Instead the storm strengthened rapidly over the warm Gulf and headed west-northwest toward Texas. Storm warnings were raised in Galveston on 7 September, and the local Weather Bureau official, Isaac Cline, became concerned as swells grew and the tide rose despite an offshore wind. There was no telegraph from ships at sea and no means of measuring the storm’s power before it arrived.

What happened on 8 September 1900

On the morning of 8 September water was already flooding low streets near the beach. Crowds came to watch the surf, and some residents left for the mainland, but most stayed. By early afternoon the bridges to the mainland were under water and escape was no longer possible.

The hurricane made landfall that evening just southwest of the city. Modern reanalysis classes it as a Category 4 storm with sustained winds of about 140 miles per hour (225 km/h). The barometer fell to around 28.48 inches of mercury in Galveston, among the lowest readings then recorded in the United States.

The worst damage came from the storm surge, which reached about 15 feet. The entire island was submerged. Houses near the beach collapsed, and their timbers formed a moving wall of debris that the waves drove inland, smashing building after building. Many people died crushed by wreckage or drowned when the houses where they had taken shelter gave way.

The water began to fall during the night. By the morning of 9 September survivors saw a city in which roughly a third of the buildings had vanished and a long ridge of wreckage marked where the debris had stopped.

Key people

Isaac Cline was the head of the Weather Bureau office in Galveston. Later accounts credited him with riding along the beach to warn residents, though the details of his actions are debated. His own house, where dozens of people had sheltered, was destroyed, and his wife, Cora, died.

Willis L. Moore, chief of the US Weather Bureau, was criticised for the bureau’s forecasting and for dismissing Cuban warnings. The disaster contributed to later improvements in hurricane forecasting and international cooperation.

Clara Barton, aged 78, led the American Red Cross to Galveston in what proved to be her last major relief operation. The Red Cross distributed food, clothing and building materials and helped set up an orphanage.

Henry M. Robert, a retired army general and author of Robert’s Rules of Order, served on the engineering board that designed the seawall.

The aftermath

The scale of death overwhelmed the survivors. At first bodies were loaded onto barges, weighted and dumped at sea, but many washed back onto the beaches. Officials then ordered the dead to be burned in funeral pyres, which continued for weeks. Forced labour gangs were used to recover bodies, and looting was punished harshly by martial law.

Among the most remembered losses was St. Mary’s Orphan Asylum, near the beach, where ten Sisters of Charity of the Incarnate Word and about 90 children died. According to the usual accounts, the sisters tied children to themselves with clothesline in an attempt to keep them together; three boys survived.

More than 3,600 homes were destroyed and damage was estimated at around $20-30 million in 1900 values. Thousands of survivors lived in tents along the beach, and many left the island for good.

News of the disaster reached the outside world slowly. Telegraph and telephone lines were down, and a small party of survivors had to cross the bay by boat and travel on to Houston before word could be sent to the rest of the country. Early reports badly underestimated the dead, and the true scale became clear only over the following days.

Help soon arrived from across the country. Relief trains brought food, water and medical supplies, and donations of money flowed in from cities, businesses and individuals in the United States and abroad. Water was a critical problem, since the island’s cisterns had been contaminated by salt water, and supplies had to be shipped in from the mainland.

Debate over the death toll began at once. Many victims were washed out to sea or buried under wreckage, and whole families vanished without anyone left to report them missing. Lists of named victims compiled later fall well short of most estimates of the true toll, which for the island is often put at 8,000 to 10,000, and up to 12,000 when deaths on the nearby mainland are included.

Rebuilding: the seawall and the grade raising

Galveston’s leaders decided to protect the city rather than abandon it. An engineering board including Henry M. Robert, Alfred Noble and H. C. Ripley designed a concrete seawall along the Gulf shore. The first section, about 3 miles (5 km) long and 17 feet high, was built between 1902 and 1904. The wall was later extended to about 10 miles.

The board also proposed raising the city itself. Between 1903 and 1911, workers dredged sand from the shipping channel and pumped it as a slurry into areas enclosed by dikes. More than 2,000 buildings, including the large St. Patrick’s Church, were lifted on jacks while the fill was placed beneath them. The ground was raised by as much as 17 feet near the seawall, sloping down toward the bay.

The defences were tested by another major hurricane in 1915. Damage was serious and some 275 people died along the coast, but the city behind the seawall survived far better than in 1900.

Political and economic consequences

The disaster led to a new form of city government. In 1901 Galveston replaced its mayor and council with a small commission of businessmen, each responsible for a department. The “Galveston plan” of commission government spread to hundreds of American cities in the following decades.

Economically, the storm marked a turning point. Investors grew wary of the exposed island, and the inland city of Houston pressed ahead with its ship channel, which opened to deep-water traffic in 1914. Houston soon overtook Galveston as the region’s leading port and city.

Legacy

The Galveston hurricane remains the benchmark for disaster in the United States, with a death toll greater than that of any other American storm, earthquake or flood. Memorials on the seawall and in the city commemorate the dead, and the story is retold in works such as Erik Larson’s Isaac’s Storm.

The storm reshaped hurricane science and emergency planning. Later disasters such as the Okeechobee hurricane of 1928 and Hurricane Katrina in 2005 renewed debate about the limits of coastal defences. Along with disasters such as the Johnstown Flood, it also helped establish the American Red Cross as a national relief organisation.

Why it matters

The Galveston hurricane showed how vulnerable a growing coastal city could be to a storm surge, and how poor forecasting could turn a natural hazard into a catastrophe. The city’s bold response, building a seawall and raising its ground, remains one of the most ambitious examples of adapting a city to the threat of the sea.
