On 21 October 1966 a spoil tip (a wall build to hold debrie from coal mining) collapsed, which caused the tip of a mountain to collapse down into a Welsh village.

There were multiple spoil tips on the mountain next to the Welsh village of Aberfan, which had accumulated much debris and water from multiple storms. The spoil tips could no longer hold all of it which made them to collapse, causing a landslide down the mountain side into Aberfan where it hit a primary school and other houses.

The tip was the responsibility of the National Coal Board (NCB), on which the Justice Ministry placed the sole blame after an investigation. The disaster killed 144 people, 116 of them children in the school, and a huge amount of monetary damages.

The whole disaster presented an earthquake in Prime Minister Sir Harold Wilson's tenure, whose government faced yet more criticism. The site was visited by many, including the late Queen Elizabeth II and The Prince Philip, Duke of Edinburgh.

The Camp Fire was the deadliest and most destructive wildfire in California history.

Where:

The fire occurred in Butte County, Northern California.

The town of Paradise was hit hardest and was nearly completely destroyed.

Other nearby communities affected included Concow, Magalia, and Butte Creek Canyon.

When:

It ignited on November 8, 2018, and was fully contained by November 25, 2018.

Why:

The fire was caused by electrical transmission lines owned and operated by Pacific Gas and Electric (PG&E).

High winds and dry conditions fueled the flames.

PG&E later admitted responsibility for the fire, and the company faced massive lawsuits, eventually filing for bankruptcy in 2019.

What Happened:

The fire spread incredibly fast—within just a few hours, it engulfed Paradise.

85 people died, many while trying to flee in their vehicles.

Over 18,800 structures were destroyed, including nearly 14,000 homes.

The fire burned 153,336 acres.

Thousands were left homeless, and the town of Paradise was essentially wiped off the map.

The disaster led to changes in wildfire response and utility management in California.

It was a tragic event that highlighted the growing danger of wildfires in the context of climate change, aging infrastructure, and poor forest control.

WHEN?

1930-1936

WHERE?

The Great Plains of the US that extended over Colorado, Kansas, Texas, Oklahoma and Mexico.

Great Plains is a flat area of grassland where they produced wheat and grains.

WHY?

It was caused by a mix of prolonged drought and over-farming. There was not much rain so the drought occured.

With all the winds the sand was swept up in the air forming huge clouds of dust. A lot of people from the area had to migrate because it was hard to breath in that environment.

EFFECTS:

Mass migrations

Agricultural Collapse

Dust pneumonia among many people especially children and the elderly

Changes in the US farming practice so it doesn't happen again

Changes in the government policy related to land use and soil conservation

The Chernobyl disaster was a catastrophic nuclear accident that occurred during a safety test at the Chernobyl Nuclear Power Plant. A reactor exploded, releasing massive amounts of radioactive material into the atmosphere. It happened on April 26th, 1986. The disaster occurred in Pripyat, a city in northern Ukraine, which was then part of the Soviet Union. The accident was caused by a flawed reactor design and serious mistakes made by the plant operators during a safety test. They turned off critical safety systems, which led to an uncontrollable reaction and explosion. 2 workers died during the explosion, and about 28 emergency workers died within weeks from acute radiation sickness. Thousands developed cancer and other illnesses due to radiation exposure. Radioactive fallout spread across Europe, contaminating large areas. A 30-kilometer area around Chernobyl remains mostly uninhabited. The disaster cost billions in cleanup, resettlement, and health care.
