[There were no deaths due to deterministic effects (i.e., people receiving a high dose of radiation, rapidly becoming ill, and dying); the 100–240 figure is an estimate of the number of people who died later in life due to cancer caused by radiation from the accident [29]]. 95–4,000+ [30] [31] 26 April 1986 Chernobyl disaster.
A natural disaster is a sudden event that causes widespread destruction, major collateral damage, or loss of life, brought about by forces other than the acts of human beings. A natural disaster might be caused by earthquakes, flooding, volcanic eruption, landslide, hurricanes, etc.

The researchers knew life could return after such awful conditions — we wouldn't be around if it couldn't. But how long it would take and what recovery would look like remained to be seen.
The worst Phanerozoic event, the Permian–Triassic extinction, devastated life on Earth, killing over 90% of species. Life seemed to recover quickly after the P-T extinction, but this was mostly in the form of disaster taxa, such as the hardy Lystrosaurus. The most recent research indicates that the specialized animals that formed complex ...

Under certain circumstances, these events are thought to produce massive bursts of gamma radiation emanating outward from the axis of rotation of the star. If such an event were to occur oriented towards the Earth, the massive amounts of gamma radiation could significantly affect the Earth's atmosphere and pose an existential threat to all life.
