A large earthquake causes heavy damage and loss of life in Istanbul and the Marmara region.

A devastating earthquake strikes Istanbul and the Marmara region, causing widespread destruction and loss of life.
On May 22, 1766, a powerful earthquake estimated at magnitude 7.1 rocked Istanbul and the surrounding Marmara region of the Ottoman Empire. Many historic mosques, palaces, and residential areas suffered severe damage or collapse, leaving thousands homeless. Contemporary accounts describe scenes of chaos as aftershocks continued to rattle the city. The disaster prompted relief efforts by local authorities and the central government in Constantinople. Reconstruction of key landmarks, including the Ayasofya and the Grand Bazaar, would take years. The event remains one of the most destructive earthquakes in Istanbul's recorded history.

Lassen Peak erupts with a powerful force, the only volcano besides Mount St. Helens to erupt in the contiguous U.S. during the 20th century.

Lassen Peak erupted with exceptional force, one of only two significant volcanic eruptions in the contiguous United States during the 20th century.
Lassen Peak in northern California erupted on May 22, 1915, sending explosive ash columns miles into the sky. This eruption was the only major volcanic event in the lower 48 states besides Mount St. Helens in 1980. The explosion deposited ash across towns, disrupted rail service, and altered the landscape around the mountain. Black lava flows and pyroclastic debris reshaped the nearby terrain. Scientists later studied the eruption to understand Cascade Range volcanism. Lassen Peak's activity led to the creation of Lassen Volcanic National Park in 1916, preserving its unique geological features. The eruption remains a landmark event in American volcanic history.

Three trains collide in the Quintinshill rail disaster near Gretna Green, Scotland, killing 227 people and injuring 246.

Britain's worst rail accident, the Quintinshill disaster near Gretna Green, killed 227 people when three trains collided.
On the morning of May 22, 1915, a series of signal errors and scheduling mistakes led to three trains colliding at Quintinshill, near Gretna Green in Scotland. The accident involved an overcrowded troop train, a local passenger service, and a northbound express. Estimates put the death toll at 227 soldiers and civilians, with 246 more injured, making it the deadliest rail disaster in British history. Rescue efforts were hampered by wartime conditions and the remote location. The tragedy prompted a full public inquiry and led to major reforms in railway signaling and operational protocols. Memorials erected at the site honor the victims and underscore the importance of railway safety. Quintinshill remains a somber reminder of the human cost of technical failures.

Near Xining, China, an 8.3 magnitude earthquake causes 200,000 deaths in one of the world's most destructive earthquakes.

A devastating 8.3 magnitude earthquake struck near Xining in China, claiming around 200,000 lives in one of history's deadliest quakes.
On May 22, 1927, an intense earthquake measuring 8.3 struck near Xining in northwestern China. The tremor triggered massive landslides and collapsed buildings across the remote Qinghai region. Communication and relief efforts were severely limited, leaving many survivors without aid for days. Official estimates record approximately 200,000 fatalities, though the true toll may never be known. The disaster highlighted the vulnerability of rural communities to seismic hazards. It became a case study for geologists studying the tectonic activity of the Tibetan Plateau. The Xining earthquake remains one of the most destructive natural disasters of the early 20th century.

The Great Chilean earthquake, measuring 9.5 on the moment magnitude scale, hits southern Chile, becoming the most powerful earthquake ever recorded.

The 1960 Great Chilean earthquake struck southern Chile with a magnitude of 9.5, making it the most powerful earthquake ever recorded.
On May 22, 1960, southern Chile was devastated by the Great Chilean earthquake, which registered 9.5 on the moment magnitude scale. The quake remains the largest ever instrumentally recorded. It generated massive tsunamis that traveled across the Pacific, causing damage in Hawaii, Japan, and the Philippines. Thousands of lives were lost and hundreds of thousands were left homeless in Chile. Entire towns were flattened and vital infrastructure was destroyed, plunging the region into crisis. International aid efforts were mobilized to assist survivors and rebuild communities. The disaster prompted scientific studies that advanced the understanding of plate tectonics and earthquake prediction. Chile’s recovery became a testament to resilience and global solidarity.
