A storm surge, storm flood, tidal surge, or storm tide is a coastal flood or tsunami-like phenomenon of rising water commonly associated with low-pressure weather systems, such as cyclones. It is measured as the rise in water level above the normal tidal level, and does not include waves.
The 1970 Bhola cyclone was a devastating tropical cyclone that struck East Pakistan and India's West Bengal on 12 November 1970. It remains the deadliest tropical cyclone ever recorded and one of the world's deadliest humanitarian disasters. At least 300,000 people died in the storm, possibly as many as 500,000, primarily as a result of the storm surge that flooded much of the low-lying islands of the Ganges Delta. Bhola was the sixth and strongest cyclonic storm of the 1970 North Indian Ocean cyclone season.
Natural calamities in India, many of them related to the climate of India, causes of the massive losses of life and property. Droughts, flash floods, cyclones, avalanches, landslides brought by torrential rains, and snowstorms pose the greatest threats. A natural disaster might be caused by earthquakes, flooding, volcanic eruption, landslides, hurricanes etc. In order to be classified as a disaster, it will need to have a profound environmental effect and/or human loss and frequently incurs a financial loss. Other dangers include frequent summer dust storms, which usually track from north to south; they cause extensive property damage in North India and deposit large amounts of dust and dirt from arid regions. Hail is also common in parts of India, causing severe damage to standing crops such as rice and wheat and many more crops and effects many people.
The following are lists of disasters.
The National Disaster Management Authority, is an autonomous and constitutionally established federal authority mandated to deal with the whole spectrum of disasters and their management in the country.
Operation Surya Hope was the Indian Army’s Central Command response to the June 2013 North India floods in Uttarakhand.
The Disaster Management Act, 2005, No. 53 of 2005, was passed by the Rajya Sabha, the upper house of the Parliament of India on 28 November, and the Lok Sabha, the lower house of the Parliament, on 12 December 2005. It received the assent of The President of India on 23 December 2005. The Disaster Management Act, 2005 has 11 chapters and 79 sections. The Act extends to the whole of India.
In August 2013, Pakistan and eastern Afghanistan experienced heavy rain that led to flash flooding. More than 180 died as a result of the floods.
A series of flash floods occurred in Afghanistan beginning in June 2020, with the largest and most impactful flood occurring on 26 August 2020. They were caused by torrential rain in Charikar, Parwan Province. The August floods killed at least 179 people and injured 212 others, and destroyed hundreds of houses. The Ministry of Disaster Management has also reported some casualties and destruction of infrastructure in the provinces of Kapisa, Maidan Wardak, Nangarhar, Panjshir, and Paktia.
Tropical cyclones regularly affect the coastlines of most of Earth's major bodies of water along the Atlantic, Pacific, and Indian oceans. Also known as hurricanes, typhoons, or other names, tropical cyclones have caused significant destruction and loss of human life, resulting in about 2 million deaths since the 19th century. Powerful cyclones that make landfall – moving from the ocean to over land – are some of the most impactful, although that is not always the case. An average of 86 tropical cyclones of tropical storm intensity form annually worldwide, with 47 reaching hurricane/typhoon strength, and 20 becoming intense tropical cyclones, super typhoons, or major hurricanes.
In 2016 Pakistan experienced higher rainfall than normal (10-20%), especially in the pre-monsoon season. Heavy monsoon rains are common in the region. This led to multiple periods of flooding, landslides, and damage particularly in Northern Pakistan. The Swat River overflowed and multiple landslides occurred around Pakistan including in Khyber Pakhtunkhwa, Gilgit-Baltistan, Azad Jammu, and Kashmir.
The following is a list of weather events that occurred on Earth in the year 2002.

The deadliest disaster was a heat wave in India in May, which killed more than 1,030 people. The costliest event of the year was a flood in Europe in August, which killed 232 people and caused €27.7 billion (US$27.115 billion) in damage. In September, Typhoon Rusa struck South Korea, killing at least 213 people and causing at least ₩5.148 trillion (US$4.2 billion) in damage.
From January to October 2022, excessive rainfall and widespread monsoon flooding occurred in the South Asian countries of Afghanistan, Bangladesh, India, Nepal, Pakistan, and Sri Lanka. It has become the region's deadliest floods since 2020, with over 4,700 people dead.
The 2023 Pakistan floods occurred from March to July of 2023, caused by monsoon rains which returned to Pakistan after nine months after the 2022 Pakistan floods. Floods worsened at the end of June due to upcoming monsoon rains. At least 159 people were killed, including many children.
