Pre-1980 North Indian Ocean cyclone seasons

The years before 1980 featured the pre-1980 North Indian Ocean cyclone seasons. Each season was an ongoing event in the annual cycle of tropical cyclone formation. The North Indian tropical cyclone season has no bounds, but they tend to form between April and December, peaks in May and November. These dates conventionally delimit the period of each year when most tropical cyclones form in the northern Indian Ocean. Below are the most significant cyclones in the time period. Because much of the North Indian coastline is near sea level and prone to flooding, these cyclones can easily kill many with storm surge and flooding. These cyclones are among the deadliest on earth in terms of numbers killed.


1721 Madras cyclone

It was a cyclone which struck the city of Madras (now Chennai) in the Madras Presidency on 13 and 14 November 1721. The cyclone was one of the most severe in the history of the city and destroyed bridges and even suburban villages. The damages were high and three ships of the British East India Company were lost. The Island Bridge connecting Fort St George with The Island was badly damaged as a result of the cyclone.

1737 Calcutta Cyclone

On 7 October 1737, a natural disaster struck the city of Calcutta (modern-day Kolkata) in India. For a long time this was believed in Europe to have been the result of an earthquake, but it is now believed to have been a tropical cyclone.[1][2] Thomas Joshua Moore, the duties collector for the British East India Company in Calcutta, wrote in his official report that a storm and flood had destroyed nearly all the thatched buildings and killed 3,000 of the city's inhabitants. Other reports from merchant ships indicated an earthquake and tidal surge were to blame, destroying 20,000 ships in the harbor and killing 300,000 people. It should be noted that the population of Calcutta at the time was around 3,000-20,000.[2][3]

Although there seems to be little evidence for the popular figure of 300,000 deaths[4] or for the existence of an earthquake at all, it is this number that shows up in popular literature.[3] At the same time, the figure of 3000 is only an estimation of the number of deaths inside the city itself.[5] This apparent incongruity in the data suggests a possible mix-up with the numbers for the 1839 Coringa cyclone mentioned in this article, which also suggest 20,000 sunk ships and 300,000 fatalities. Both of these figures may stem from the 300,000 figure in the 1737 super cyclone in the West Bengal region as neither one has similar numbers according to the National Cyclone Risk Mitigation Project's site.

December 1789 Indian Cyclone

Strong storm surge from a cyclone that hit Coringa, India destroyed the port and killed 20,000.[6]

Early 1800s

1831 Odisha cyclone

An intense cyclone struck Odisha.[7]

1833 West Bengal cyclone

A ship reported a pressure of 891 mbar (26.30 inHg) at Khijri, India.[8]

November 1839 Coringa cyclone

For a similar cyclone in terms of storm surge and (possibly) size, see Cyclone Mahina.

On 25 November 1839, an enormous cyclone caused a 40-foot storm surge that hit Coringa, Andhra Pradesh, wiped out the harbor city, destroyed vessels in its bay, and killed 300,000 people.[6] Survivors never entirely rebuilt the city.

Bengal cyclone of October 1847

This intense cyclone moved into Bengal state. A total of 75,000 people and 6000 cattle perished during the storm.[9]

Late 1800s

1864 Calcutta Cyclone

The 1864 Calcutta Cyclone

On October 5, a powerful cyclone hit near Calcutta, India, killing around 60,000 people.[10] The anemometer in the city was blown away during the cyclone. Over 100 brick homes and tens of thousands of tiled and straw huts were leveled. Most ships in the harbor (172 out of 195) were either damaged or destroyed.[11] The cyclone of 1864 destroyed the ports at Khejuri and Hijli.[12]

November 1867 Great Calcutta cyclone

The anemometer in the city was blown away during the cyclone. A lack of storm surge minimized the overall damage from this system.[11]

October 1874 Bengal cyclone

This severe cyclone killed 80,000 people and caused significant damage.[9]

October 1876 Backergunge cyclone

On October 31, a cyclone hit the Meghna River Delta area of India. The storm surge killed 100,000, and the disease after the storm killed another 100,000.[6]

June 1885 Aden cyclone

A cyclone had formed near the Laccadive Islands on May 24, 555 kilometres (345 mi) west of southern India. The SS Mergui encountered the cyclone off the Horn of Africa, 400 kilometres (250 mi) east of Socotra on June 1 and reported it stronger than the tropical cyclone which struck Calcutta in 1864. Just before midnight on the night of June 1, the Diomed reported winds of hurricane force and a pressure of 984 millibars (29.1 inHg). The ship Peshawar reported a westerly hurricane at the east end of the Gulf of Aden towards midnight on the night of June 2. At noon on June 3, the Tantallon reported a pressure of 943 millibars (27.8 inHg) near 12.5N 45.5E. On June 3, the German corvette Augusta, the French dispatch boat Renard, and the British ship SS Speke Hall were lost in the storm in the Gulf of Aden. The system continued westward and shrank in scale as it moved into the entrance of the Red Sea, crossing the coast of Djibouti.[13]

1885 Odisha cyclone

An intense cyclone struck Odisha.[7] it killed one person.

June 1890 Muscat cyclone

This system formed off the west coast of India during the first week of June and moved northwest towards the Arabian peninsula. Approaching the Gulf of Oman, strong winds and heavy rains affected Sur during the afternoon on June 4. Rain spread west that evening towards Muscat, where winds increased to hurricane-force from the north-northeast early on June 5. The eye of the storm made landfall at Sohar at dusk on June 5, eventually dissipating well inland. Heavy rains fell at the hospital in Muscat, where 11.24 inches (285 mm) were recorded. This led to flooding which took several hundred lives. Several thousand date trees were uprooted by the storm's winds and carried away by its floods. Several homes were leveled in Muscat and Mutrah. Fifty perished from downing near the coast or being buried by debris. Overall, 727 people lost their lives.[13]

May 1959 Salalah cyclone

This system first became a low-pressure area near the Laccadive Islands on May 19, tracking northwest towards the Arabian peninsula. The system made landfall at Raysut on May 24. At Salalah, skies clouded over on May 23 as the pressure fell significantly. Winds turned northerly before midnight that night. At 1 a.m. on May 24 the peak of the storm's winds arrived. Maximum sustained winds were estimated at 70 knots (130 km/h) and the pressure at Salalaha fell to 968 millibars (28.6 inHg). Many vessels offshore, including two large passenger ships, went to pieces. Five buildings collapsed and several roofs were blown away by the cyclone. Salalah recorded 82 millimetres (3.2 in) of rain at their airport. A total of 141 lives from the ship Samha were taken during this tempest.[13]



Track map of all storms during the 1960 season

Fifteen depressions developed during the course of the 1960 season, with five becoming cyclonic storms. The majority of activity took place in the Bay of Bengal, with eleven cyclones forming there. The season's first storm formed over the Arabian Sea on May 10. Though it remained over water for its entire existence, several vessels encountered the storm and reported hurricane-force winds as well as a pressure of 974 mbar (hPa; 28.77 inHg). The deadliest and most intense cyclone of the season was Severe Cyclonic Storm Ten, which killed 14,174 in East Pakistan in early November. Attaining peak winds estimated at 150 km/h (90 mph) and a pressure of 966.7 mbar (hPa; 28.55 inHg), it struck just three weeks after the previous system devastated the same area. Producing a 6.1 m (20 ft) storm tide that swept 16 km (10 mi) inland, several coastal islands were completely submerged. An estimated 200,000–300,000 were left homeless in the wake of the two storms. These systems marked the start of an unusually active period of cyclones impacting East Pakistan, culminating ten years later with the 1970 Bhola cyclone that killed 300,000–500,000 people. During the course of the season, several depressions impacted India, each producing heavy rain. Collectively, these systems killed 125 people.

May Salalah cyclone

On May 19, a tropical disturbance formed over the Laccadive Islands, before tracking northwest towards the Arabian peninsula. The system achieved cyclone intensity on May 22. A United States Weather Bureau research flight flew into the 12 nautical miles (22 km)-wide eye of the hurricane-strength system, and found a central pressure of 947 millibars (28.0 inHg). A ship 111 kilometres (69 mi) west of the system reported winds of 68 knots (126 km/h). At Salalah, a strong northerly wind set in during the morning of May 25. Later in the day, winds increased to gale force and a sandstorm reduced visibility to 400 metres (1,300 ft). Later in the day of May 26 winds again increased to gale force and another sandstorm reduced visibility to 500 metres (1,600 ft). As winds increased to 60 knots (110 km/h) the sandstorm became more severe, with visibility restricted to 50 metres (160 ft). Late on the night of the 26th, winds shifted to northeast and heavy rains fell across the region through the morning hours. Skies remained cloudy with periods of rain into May 28. A total of 230 millimetres (9.1 in) was recorded at Salalah.[13]

Map plotting the track and intensity of the storm according to the Saffir–Simpson hurricane wind scale

The 1970 Bhola cyclone was a devastating tropical cyclone that struck East Pakistan (now Bangladesh) and India's West Bengal on November 12, 1970. It was the deadliest tropical cyclone ever recorded, and one of the deadliest natural disasters in modern times.[25] Up to 500,000 people lost their lives in the storm, primarily as a result of the storm surge that flooded much of the low-lying islands of the Ganges Delta. This cyclone was the sixth cyclonic storm of the 1970 North Indian Ocean cyclone season, and also the season's strongest, reaching a strength equivalent to a Category 3 hurricane.

The cyclone formed over the central Bay of Bengal on November 8 and travelled north, intensifying as it did so. It reached its peak with winds of 185 km/h (115 mph) on November 12, and made landfall on the coast of East Pakistan that night. The storm surge devastated many of the offshore islands, wiping out villages and destroying crops throughout the region. In the most severely affected Thana, Tazumuddin, over 45% of the population of 167,000 was killed by the storm.

The Pakistani government was severely criticized for its handling of the relief operations following the storm, both by local political leaders in East Pakistan and in the international media. The opposition Awami League gained a landslide victory in the province, and continuing unrest between East Pakistan and the central government triggered the Bangladesh Liberation War, which concluded with the creation of the country of Bangladesh.

Main article: 1977 Oman cyclone

On June 9, a tropical disturbance was noted off the west coast of India in the Arabian Sea. The system moved northward, followed by a northwest turn on June 10 while the system intensified into a tropical storm. It curved toward the west, and the JTWC reported the cyclone as reaching peak winds of 70 mph (110 km/h) on June 11. The JTWC issued the final advisory at 0800 UTC on June 13 as the storm was making landfall on Masirah Island.[30] The Oman Department of Meteorology reported the storm as being much stronger than the JTWC, with sustained winds of 105 mph (165 km/h) with gusts to 140 mph (230 km/h).[31] Shortly after striking Masirah, the storm moved ashore mainland Oman, causing rapid weakening to tropical depression status. The system dissipated on June 14 after crossing into southeastern Saudi Arabia.[30]

The cyclone was the strongest on record to make landfall on the Arabian Peninsula, until Cyclone Gonu surpassed it in 2007.[32][33] Overall, the cyclone caused 105 deaths and 48 injuries,[34] and 50,000 people were left homeless.[35]
