Three weeks ago, on September 1, Hurricane Dorian savaged the Bahamas, a chain of islands east of Florida in the Atlantic Ocean. In the slang of the islands, Dorian mashed up (devastated) much of Grand Bahama and the Abaco Islands in the northwestern part of the archipelago. Dorian, one of the strongest hurricanes on record to strike the Bahamas, killed at least 53 people there. That number will almost certainly skyrocket, however, as more than 600 people remain missing.

Dorian struck the Bahamas as a category 5 storm on the Saffir-simpson scale, which measures hurricane intensity. Category 5 is the strongest hurricane rating, with winds above 157 miles (252 kilometers) per hour. Hurricanes of this strength typically occur about every three years, but Dorian marked the fourth consecutive year that a category 5 hurricane has struck the Caribbean, with two striking in 2017 when Irma and Maria killed more than 3,000 people, mostly in Puerto Rico. Hurricanes of all categories can cause terrible destruction and loss of life, but category 5 hurricanes are labeled “catastrophic” by the United States National Oceanic and Atmospheric Administration (NOAA). Winds that strong will destroy most framed houses by tearing away roofs and collapsing walls. They will flatten trees and electric power poles and leave residential areas uninhabitable for weeks or months. Increases in the intensity of hurricanes and other bad weather align with what scientists expect as the world’s climate continues to change.

Dorian formed as a tropical depression over the Atlantic Ocean on August 24. A tropical depression is a low-pressure area surrounded by winds that have begun to blow in a circular pattern. Dorian developed into a hurricane four days later. The storm rapidly gained size and strength, reaching category 5 status by September 1. That day, the massive hurricane hit Elbow Cay and Great Abaco Island before moving on to Grand Bahama, where Dorian lingered for more than 24 devastating hours. Dorian lashed the islands with sustained winds of 185 miles (300 kilometers) per hour and gusts over 220 miles (350 kilometers) per hour. Storm surges (sudden onrushes of seawater) and torrential rains caused deadly flooding in many parts of the low-lying islands.

Dorian then spun away along the coasts of eastern Florida, Georgia, and South Carolina, greatly diminishing to a category 1—but still dangerous—hurricane before hitting Cape Hatteras in North Carolina’s Outer Banks on September 6. From there, Dorian further downgraded to an extratropical cyclone (a stormy low pressure system) and raced northward off the U.S. east coast. On September 7, Dorian’s final gasp brought heavy rains and fierce winds to Newfoundland and Nova Scotia in Canada. The storm at last dissipated near Greenland on September 10.

Dorian threatened many areas, and states of emergency were declared in several Caribbean and Atlantic islands and eastern U.S. states. But the storm’s rapid degradation after striking the Bahamas greatly reduced its deadliness. Dorian still killed people—directly or indirectly—outside the Bahamas, however, including one person in Puerto Rico, six people in Florida, and three people in North Carolina. Direct deaths are caused by such things as blown debris, flooding, or falling trees. Indirect deaths include people who die by accident or heart attacks while involved in storm-related activities, such as clearing trees or boarding up houses. They also include those who die in car accidents trying to evacuate.

On Dec. 30, 1903, 115 years ago this Sunday, a fire at the Iroquois Theater in downtown Chicago killed 602 people. The disaster was the worst theater fire and worst single-building fire in United States history. It resulted in the institution of new fire safety laws and building codes to help prevent such a disaster from ever happening again.

The Iroquois Theater had opened just a month before the fire, on Nov. 23, 1903. The beautiful new theater was claimed to be “fireproof,” but many basic fire precautions were overlooked as the owners rushed to open the building for the lucrative holiday season. The giant theater—with seating for some 1,600 people plus “standing room” for hundreds more—had no fire alarms or sprinklers and emergency smoke vents above the stage were nailed shut. Exit doors opened only inward, many structures and fixtures contained oil-based paint and other highly flammable materials, and the theater’s seating levels were separated by locking gates. The lack of care and attention given to fire safety at the Iroquois Theater proved to be disastrous.

The Iroquois Theater presented Mr. Bluebeard, a musical comedy, to a crowd of over 1,900 people on the afternoon of Dec 30, 1903. Another 400 performers and theater workers were crowded into the basement dressing rooms and backstage areas. During the show, a floodlight over the stage exploded, setting fire to a velvet curtain. The fire quickly spread to the oil-painted wood and canvas set pieces hanging in the catwalks and soon flaming debris was falling to the stage. An actor pleaded for people to remain calm, but the audience panicked and tried to flee the theater, which was quickly filling with flames and smoke.

Unfortunately, many of the theater’s exits were locked or hidden behind curtains. Other doors were unlocked, but they only opened inward, trapping people as they were pressed from behind by more and more people. The trapped people were quickly overcome by flames and smoke. After a stagehand ran to the nearest fire station, firefighters arrived to find theater doors blocked by bodies on the inside. At last, firefighters worked their way into the theater and extinguished the flames, but the damage had been done. Hundreds of dead bodies lay in the theater, and more people died from injuries in the coming days.

Investigations into the fire found numerous violations and irresponsible building practices. In the coming months and years, new fire safety laws required unlocked, outward-opening doors in theaters as well as occupancy limits, wider aisles, exit lights, automatic sprinklers, fire alarm systems, and flame resistant scenery, props, and curtains.

At around noon on Sunday, June 3, the Volcán de Fuego (Volcano of Fire) erupted in southern Guatemala, a nation in Central America. The explosive eruption forced a massive ash cloud more than 6 miles (10 kilometers) into the air, blotting out the sun and darkening the immediate area. The volcano also spewed lava and rock, and a super-heated mass of gas and volcanic material known as a pyroclastic flow raced down the volcano’s sides and engulfed nearby communities. Fuego has since continued to erupt, but its intensity has greatly diminished. The Guatemalan military is helping local firefighters, police, and volunteers rescue people trapped in the ashy mud and recover and count the bodies of the dead. Thus far, the volcanic eruption has killed 109 people and injured more than 300 others. Many people remain missing, and thousands of people have been forced from their homes.

The towns of El Rodeo, Las Lajas, and San Miguel Los Lotes—those closest to Volcán de Fuego—were partially buried beneath volcanic mud and soot. Other areas were hit too as the pyroclastic flow burned and buried the people, homes, and vehicles in its path. Layers of volcanic ash covered nearby Antigua, a colonial city some 27 miles (44 kilometers) southwest of Guatemala City, the nation’s capital. Ash forced the closure of Guatemala City’s La Aurora International Airport, and the government warned of significant amounts of ash and toxic gases in the air. The government also warned of the threat of mudslides, as heavy rains could dislodge solidified volcanic material from Fuego’s steep sides and foothills. Local streams and waterways are clogged with ash, and the toll on area plant and animal life will be significant.

Fuego’s peak soars 12,346 feet (3,763 meters) above sea level. It is a stratovolcano, a tall volcanic mountain that typically has steep sides. Fuego is one of Central America’s most active volcanoes, and it is in a state of near-constant eruption. It has experienced more than 60 significant eruptions since the arrival of Spanish explorers in the area in 1524, but few of the events have resulted in human fatalities. Sunday’s eruption was by far Fuego’s largest and deadliest. The worst eruption in Guatemala’s recorded history took place at the nearby Volcán Santa María in 1902, an event that killed thousands of people.

Guatemala sits on the infamous Ring of Fire, a turbulent zone of frequent seismic and volcanic activity along the islands and continents rimming the Pacific Ocean. Fuego and its neighbor volcano, Acatenango, form a complex known as La Horqueta (The Pitchfork). People hike and climb the summit of the much quieter and safer Acatenango for a view of the constantly rumbling Volcán de Fuego.

Two days ago, on September 19, a powerful 7.1-magnitude earthquake struck central Mexico, collapsing buildings and killing more than 240 people in Mexico City, the capital, and in the states of Guerrero, México, Morelos, Oaxaca, and Puebla. The earthquake struck on the anniversary of a catastrophic 1985 earthquake that killed some 10,000 people in central Mexico. The quake followed another deadly temblor that hit southern Mexico earlier in September 2017.

The earthquake’s epicenter was near the small Puebla city of Atencingo, about 75 miles (120 kilometers) southeast of Mexico City. The prolonged tremor hit at 1:14 p.m. local time—just two hours after an annual earthquake drill in Mexico City—shaking buildings and frightening people into the streets. Structures collapsed in several cities, obscuring the panicked survivors in dust clouds amid the blaring din of alarm sirens.

Emergency responders rushed to the first scenes of destruction. Unstable rubble and electric power outages hampered rescue efforts, and widespread damage meant many ravaged places went hours without help. Military personnel and civilian volunteers aided emergency workers as they searched through the night for survivors. Sniffer dogs followed human scents, and workers pleaded for silence, hoping to hear the calls of people trapped beneath the destruction. Many people were saved, but the body count rose quickly as splintered wood, shattered masonry, and chunks of concrete were frantically removed. Many people remain missing amid the devastation, and the disaster’s death toll—245 as of this morning—will almost certainly rise.

In Mexico City, more than 90 people have died, including 21 children and 5 adults killed when an elementary school collapsed in the city’s southern Coapa district. More than 70 people were killed in Morelos, just south of Mexico City, and more than 40 died in the epicenter state of Puebla. On the slopes of Popocatépetl volcano southeast of Mexico City, a church collapsed in the village of Atzitzihuacán, killing 15 people. Throughout the region, scores of buildings fell, ruptured gas lines sparked fires, and falling debris crushed cars on the streets.

Like the earthquake earlier in September in southern Mexico, Tuesday’s temblor struck near the Middle America Trench, a zone in the eastern Pacific Ocean where one slab of Earth’s crust, the Cocos Plate, is sliding beneath the North American Plate—a geological process called subduction. The Middle America Trench is part of the so-called Ring of Fire, an area of high seismic and volcanic activity that encircles the Pacific Ocean. The United States Geological Survey (USGS) issued an orange alert (the second-highest threat level) after Tuesday afternoon’s quake, warning of significant casualties and extensive and widespread damage. The alert was part of the USGS PAGER (Prompt Assessment of Global Earthquakes for Response) system that informs emergency responders, the media, and government and aid agencies of the scope of a potential disaster.

On Sept. 19, 1985, an 8.0-magnitude temblor killed some 10,000 people in Mexico City and nearby areas. About 400 buildings in the capital were destroyed in that disaster, and thousands of others suffered damage. Since then, Mexico has enacted tougher building codes and safety standards—moves that no doubt saved many lives 32 years later.

September 12, 2017

Just before midnight on Thursday, September 7, a powerful earthquake caused death and destruction in southern Mexico. The 8.1-magnitude quake, the strongest in the region in decades, centered just off the Pacific coast states of Chiapas and Oaxaca. The temblor (another word for earthquake in both English and Spanish) toppled numerous structures and killed 96 people. Many people remain missing, however, and the death toll will almost certainly rise.

The earthquake’s epicenter was in the Gulf of Tehuantepec just off the southern Mexican coast. The coastal city of Juchitán de Zaragoza bore the brunt of the earthquake’s destruction. Hundreds of buildings were destroyed there, and many thousands were damaged, including Juchitán’s historic palacio municipal (city hall). In the early hours of Friday, September 8, emergency crews, federal police, and soldiers began pulling the dead and the living from the rubble of wrecked buildings as aftershocks rocked the area, causing further damage and panic. Since then, many damaged buildings have been cleared, but strong aftershocks continue and many structures remain too unstable to enter. More than 160 area municipalities have declared states of emergency, and many thousands of people still lack electric power, running water, and phone service.

The quake struck near the Middle America Trench, a zone in the eastern Pacific Ocean where one slab of Earth’s crust, the Cocos Plate, is sliding beneath the North American Plate—a geological process called subduction. The Middle America Trench is part of the so-called Ring of Fire, an area of high seismic and volcanic activity that encircles the Pacific Ocean. The United States Geological Survey (USGS) issued a red alert (highest threat level) after Thursday night’s quake, warning: “High casualties and extensive damage are probable and the disaster is likely widespread.” The alert was part of the USGS PAGER (Prompt Assessment of Global Earthquakes for Response) system that informs emergency responders, the media, and government and aid agencies of the scope of a potential disaster.

Last week’s earthquake was felt throughout southern Mexico and neighboring Guatemala. Some 500 miles (800 kilometers) away in Mexico City, the capital, structures swayed and earthquake alarms caused a mild panic. Many of the city’s residents carry vivid memories of the deadliest quake in Mexican history, an 8.0-magnitude temblor in 1985 that killed some 10,000 people in the city and nearby areas. About 400 buildings in Mexico City were destroyed in that disaster, and thousands of others suffered damage. Since then, Mexico has enacted tougher building codes and safety standards.

August 23, 2017

Last week, in the early hours of August 14, heavy rains and flooding caused a massive mudslide on the outskirts of Freetown, the capital city of the small west African nation of Sierra Leone. The mudslide buried parts of Regent, a settlement perched on the slopes of Mount Sugar Loaf overlooking Freetown. The mudslide destroyed or severely damaged hundreds of homes and other buildings and killed 499 people. The death toll is certain to rise, however, as some 600 people remain missing. Rescue efforts continue a week after the disaster, but there is little hope of finding anyone alive in the mud and destruction.

The population of Freetown and its outskirts has increased sharply in recent years, and makeshift shantytowns have sprung up in Regent and other areas. As land is cleared for homes, however, the deforestation weakens the soil—particularly on the slopes of Sugar Loaf—greatly increasing the risk of land- and mudslides. Environmental groups have planted many trees, trying to replenish parts of the forest, but they can not keep up with the pace of clearing and unregulated development. Climate change, too, is adding to the problem, as more severe and erratic weather patterns bring unusually heavy rains. This summer has been exceptionally wet in and around Freetown, and floodwaters further destabilized the Sugar Loaf hillsides. Torrential downpours saturated the area in the days preceding the mudslide.

Entire parts of Regent were buried in the mudslide, which sent mucky waters cascading through other settlements and into the streets of Freetown itself. Some 3,000 people have been left homeless by the disaster, another 10,000 people have been evacuated from areas at risk of further mudslides, and the Sierra Leone government is asking thousands more to leave potentially dangerous areas. Survivors face threats from cholera and other waterborne diseases as the many deaths and destruction have tainted the area’s water supplies. International aid is pouring into Freetown, however, providing clean water, food, shelter, and medical supplies.

Further rains have hampered rescue efforts in Regent, and there is a shortage of heavy equipment to dig through and remove the many tons of mud covering homes and streets. The day after the disaster, Sierra Leone President Ernest Bai Koroma declared seven days of mourning as bodies began being retrieved and buried—most of them unidentified—in mass graves at nearby cemeteries. Since then, many survivors have ignored warnings to keep away and returned to the devastation to search for missing family members and retrieve belongings.

On August 16, two days after the disaster in Sierra Leone, a similar mountain mudslide struck the fishing village of Tora on the banks of Lake Albert in the Democratic Republic of the Congo, killing more than 200 people. There, the disaster was also caused by unusually heavy rains and deforestation for the creation of makeshift housing.

November 10, 2015

Forty years ago today, the ore freighter SS Edmund Fitzgerald broke apart and sank in heavy waves during an abrupt, unseasonable wintry storm on Lake Superior. Heading from Superior, Wisconsin, to a steel mill near Detroit, the ship—the largest ever lost on the Great Lakes—went down in Canadian waters, about 17 miles (27 kilometers) from Whitefish Bay, Wisconsin. All 29 crew members died. None of their bodies were ever recovered.

The sinking begat disbelief and morbid fascination: how could such a huge, modern ship founder in a storm on a freshwater lake, mere minutes from a safe harbor? Had the ship, as some suspected, been damaged during a shoal grounding earlier in the voyage? Had freak, towering rogue waves exploited some structural failure, and had crew failed to properly secure cargo hatches? Investigators’ theories of the sinking failed to build to a concrete conclusion, and maritime enthusiasts continue to debate the causes of the famous wreck to this day. Its wreckage rests on the lake bed—broken almost exactly in half—in about 530 feet (162 meters) of water.

The sinking shocked residents of Great Lakes shipping towns and drew attention from around the world. Writers penned numerous tributes to the lost crew. The most famous among such tributes was the haunting “Wreck of the Edmund Fitzgerald” by the Canadian folk-pop singer/songwriter Gordon Lightfoot. In 1976, the song topped the Canadian pop charts and peaked at number two in the United States. Its lyrics included the following lines:

The lake, it is said, never gives up her dead
When the skies of November turn gloomy.
With a load of iron ore twenty-six thousand tons more
Than the Edmund Fitzgerald weighed empty,
That good ship and true was a bone to be chewed
When the “Gales of November” came early.
