Aons Impact Forecasting Director and Meteorologist Steve Bowen says vulnerabilities around tropical cyclones, flooding, and wildfires were again exposed during October. Then it translated that influence into economic costs, concluding that around $8 billion in damages can be blamed on climate change. The intense rain caused many sediment disasters, including debris flows, slope failures and landslides. As the tropical air collided with higher elevations the air was forced to rise, cool and condense in a process known as orographic lift, causing a deluge that resulted in mudslides and sent rivers bursting over their banks. Characteristics of tropical cyclones Children are always most vulnerable during a crisis and in the midst of a natural disaster like Typhoon Hagibis. Storms like Hagibis are likely to grow more destructive as the world continues to warm, she said. Sustained winds at hurricane force affected downtown Tokyo, with a gust to 98 mph (158 km/hr) recorded at Haneda Airport. Typhoon Hagibis killed more than 50 people and devastated parts of northern Japan beginning Oct. 12. While the deadly storm has since been downgraded to a tropical storm, it continues .

Most of the affected areas were located near rivers, where in many cases, the dykes and floodwalls either collapsed or were overtopped. A sediment disaster can be classified as either: (1) debris flow, which involves soil and rock mix with water (rainwater and groundwater) flowing down rivers and mountain streams; (2) slope failure, which comprises abrupt collapse of slope when the soil/rock becomes unstable due to heavy rain; and (3) landslide, which involves a soil mass moving downward slowly at the boundary of the discontinuous surface under the influence of groundwater and gravity. Figure 5: Examples of breached dykes (modified from mlit.go.jp/policy/shingikai/content/001317859.pdf).

Fears of mass casualties are growing with reports of homes being buried or flooded. Various flood protection and sediment disaster measures designed from past experiences need to be re-evaluated. Typhoon Faxai, which hit Japan in September this year, will generate insurance and reinsurance payouts of $5 billion to $9 billion, according to an estimate by risk modeling agency Risk Management Solutions. Typhoon Wutip was the strongest February typhoon on record in the Northwest Pacific basin. New study calculates how much of the damage of individual extreme weather events can be attributed to human-caused climate change. More than 1000 km2 of areas near Abukuma River were inundated. In higher elevations just west of downtown Tokyo, 23.6 inches (60 centimetres) of rain fell, which was also a record. Severe flooding triggered by the torrential rain submerged large areas in central Japan. Abstract.
