Global Catastrophes
- Insured losses from natural catastrophes totaled $130 billion, 76 percent above the 21st century average, and 18 percent higher than 2020, according to the2021 Weather, Climate and Catastrophe Insightreport from Aon.
- Hurricane Ida was the largest insured loss event in 2021 and the fourth costliest hurricane on record with $36 billion in insured losses.
- There were 20 billion-dollar insured loss events in 2021, the fourth highest on record. Insured losses of $17 billion from winter weather, was the costliest on record for this peril.
- The $13 billion insured losses from European floods was the costliest disaster on record for the continent. Aon noted that roughly 38 percent of global economic losses were covered by insurance, translating to a protection gap of 62 percent.
- Natural catastrophes in 2021 resulted in a total global economic loss of $270 billion, according to Swiss Re’ssigma report. Of those global economic losses, only $111 billion were actually insured. (Aon’s and Swiss Re’s figures differ because of different collection methods and criteria for classifying events).
- According to the Swiss Re sigma report, man-made disasters totaled $10 billion in 2021, of which $8 billion were insured.
- Marsh publishes a biennial report on the 100 largest losses in the hydrocarbon industry which summarizes the largest property damage losses from the hydrocarbon extraction, transport, and processing industry between 1974 and 2021.

Nuclear incidents
The International Atomic Energy Agency (IAEA) rates the severity of nuclear incidents on the International Nuclear and Radiological Event Scale (INES) from one (indicating an anomaly) to seven (indicating a major event). The scale considers an event’s impact based on three criteria: its effect on people and the environment; whether it caused unsafe levels of radiation in a facility; and if preventive measures did not function as intended. Scales six and seven designate full meltdowns, where the nuclear fuel reactor core overheats and melts. Partial meltdowns, in which the fuel is damaged, are rated four or five.
Selected Examples of Historic Nuclear Events, as Classified by the INES Scale (1)
Level | INES description | Example | Location | Year |
---|---|---|---|---|
1 | Anomaly | Fast stop of the main circulation pumps and simultaneous loss of their fly wheel systems during reactor scram | Olkiluoto Nuclear Power Plant, Finland | 2008 |
Exposure of two workers in the nuclear power plant beyond the dose constraints | Rajasthan Nuclear Power Plant, India | 2012 | ||
2 | Incident | Reactor trip due to high pressure in the reactor pressure vessel | Laguna Verde Nuclear Power Plant, Mexico | 2011 |
Overexposure of a practitioner in interventional radiology exceeding the annual limit | Paris, France | 2013 | ||
3 | Serious incident | Release of iodine 131 into the environment from the radioelements production facility | Fleurus, Belgium | 2008 |
Severe overexposure of a radiographer | Lima, Peru | 2012 | ||
4 | Accident with local consequences | Radioactive material in scrap metal facility resulted in acute exposure of scrap dealer | New Delhi, India | 2010 |
Overexposure of four workers at an irradiation facility | Stamboliysky, Bulgaria | 2011 | ||
5 | Accident with wider consequences | Severe damage to the reactor core | Three Mile Island Nuclear Power Plant, USA | 1979 |
Four people died after being overexposed from an abandoned and ruptured high activity source | Goiania, Brazil | 1987 | ||
6 | Serious accident | Significant release of radioactive material to the environment after the explosion of a high activity waste tank | Kyshtym, Russian Federation | 1957 |
7 | Major accident | Significant release of radioactive material to the environment resulting in widespread health and environmental effects | Chernobyl, Ukraine | 1986 |
Significant release of radioactive material to the environment resulting in widespread environmental effects | f*ckushima, Japan | 2011 |
