The Cilicia earthquake occurred northeast of the city of Adana in 1268. Over 60,000 people perished in the Armenian Kingdom of Cilicia in southern Asia Minor.
The 1693 Sicily earthquake struck parts of southern Italy near Sicily, Calabria, and Malta on January 11 at around 21:00 local time. This earthquake was preceded by a damaging foreshock on January 9. The main quake had an estimated magnitude of 7.4 on the moment magnitude scale, the most powerful in Italian recorded history, and a maximum intensity of XI (Extreme) on the Mercalli intensity scale, destroying at least 70 towns and cities, seriously affecting an area of 5,600 square kilometers (2,200 sq mi) and causing the death of about 60,000 people.
The 1727 Tabriz earthquake occurred on 18 November with an epicenter near Tabriz in northwest Iran.
The 1783 Calabrian earthquakes were a sequence of five strong earthquakes that hit the region of Calabria in southern Italy (then part of the Kingdom of Naples), the first two of which produced significant tsunamis. The epicenters form a clear alignment extending nearly 100 km from the Straits of Messina to about 18 km SSW of Catanzaro. The epicenter of the first earthquake occurred in the plain of Palmi. The earthquakes occurred over a period of nearly two months, all with estimated magnitudes of 5.9 or greater. Estimates of the total number of deaths lie in the range 32,000 to 50,000.
The 1792 Unzen earthquake and tsunami resulted from the volcanic activities of Mount Unzen (in the Shimabara Peninsula of Nagasaki Prefecture, Japan) on 21 May. This caused the collapse of the southern flank of the Mayuyama dome in front of Mount Unzen, resulting in a tremendous megatsunami, killing 15,000 people altogether. It was also called Shimabara erupted, Higo affected, (Shimabara means the central mountain of the Shimabara Peninsula) since many people were killed by this tsunami in Higo (Kumamoto Prefecture, situated 20 km (12 mi) away across the Ariake Sea).
The air planes accidents happened in the twentieth century.
The Great Depression was a severe worldwide economic depression that took place mostly during the 1930s, beginning in the United States. The timing of the Great Depression varied across the world; in most countries, it started in 1929 and lasted until the 1930s. It was the longest, deepest, and most widespread depression of the 20th century. The Great Depression is commonly used as an example of how intensely the global economy can decline.
The 1932 Changma earthquake occurred at 10:04:27 local time (02:04:07 UTC) on 25 December. With an estimated magnitude of 7.6 on the surface wave magnitude scale, and a maximum felt intensity of X (Extreme) on the Mercalli intensity scale, the quake destroyed 1,167 houses and caused 275 deaths and 320 injuries.
The 1935 Quetta earthquake occurred on 31 May between 2:33 am and 3:40 am at Quetta, Balochistan, British India (now part of Pakistan). The earthquake had a magnitude of 7.7 Mw and anywhere between 30,000 and 60,000 people died from the impact. This ranked as the deadliest earthquake that hit South Asia until the 2005 Kashmir earthquake. The quake was centred 4 km south-west of Ali Jaan, Balochistan, British India.
The Rajputana famine of 1869 (also the Great Rajputana Famine, Bundelkhand and Upper Hindustan famine, Rajputana famine of 1868-70) affected an area of 296,000 square miles (770,000 km2) and a population of 44,500,000, primarily in the princely states of Rajputana, India, and the British territory of Ajmer. Other areas affected included Gujarat, the North Deccan districts, the Jubbalpore division of the Central Provinces and Berar, the Agra and Bundelkhand division of the United Provinces, and the Hissar division of the Punjab.
The 1970 Ancash earthquake (also known as the Great Peruvian earthquake) occurred on 31 May off the coast of Peru in the Pacific Ocean at 15:23:29 local time. Combined with a resultant landslide, it is the most catastrophic natural disaster in the history of Peru. Due to the large amounts of snow and ice included in the landslide that caused an estimate of 66,794 to 70,000 casualties, it is also considered to be the world's deadliest avalanche.
The Chernobyl Nuclear Power Plant is a closed nuclear power plant near the abandoned city of Pripyat in northern Ukraine, 16.5 kilometers (10 mi) northwest of the city of Chernobyl, 16 kilometers (10 mi) from the Belarus–Ukraine border, and about 100 kilometers (62 mi) north of Kyiv. It was cooled by an engineered pond, which is fed by the Pripyat River about 5 kilometers (3 mi) northwest from its juncture with the Dnieper.
The 1990 Manjil–Rudbar earthquake occurred on June 21 at 00:30:14 local time in northern Iran. The shock had a moment magnitude of 7.4 and a Mercalli Intensity of X (Extreme). Widespread damage occurred to the northwest of the capital city of Tehran, including the cities of Rudbar and Manjil. The National Geophysical Data Center estimated that $8 billion in damage occurred in the affected area. Other earthquake catalogs presented estimates of the loss of life in the range of 35,000–50,000, with a further 60,000–105,000 that were injured.
SARS-CoV is thought to be an animal virus from an as-yet-uncertain animal reservoir.
Hurricane Katrina was an extremely destructive and deadly Category 5 hurricane that made landfall on Florida and Louisiana in August 2005, causing catastrophic damage; particularly in the city of New Orleans and the surrounding areas. Subsequent flooding, caused largely as a result of fatal engineering flaws in the flood protection system known as levees around the city of New Orleans, precipitated most of the loss of lives. The storm was the third major hurricane of the record-breaking 2005 Atlantic hurricane season, as well as the fourth-most intense Atlantic hurricane on record to make landfall in the contiguous United States, behind only the 1935 Labor Day hurricane, Hurricane Camille in 1969, and Hurricane Michael in 2018.
The 2008 Sichuan earthquake also known as the Great Sichuan earthquake or Wenchuan earthquake, occurred at 14:28:01 China Standard Time on May 12, 2008. Measuring at 8.0 Ms (7.9 Mw), the earthquake's epicenter was located 80 kilometers (50 mi) west-northwest of Chengdu, the provincial capital, with a focal depth of 19 km (12 mi). The earthquake ruptured the fault for over 240 km (150 mi), with surface displacements of several meters. The earthquake was also felt in nearby countries and as far away as both Beijing and Shanghai—1,500 and 1,700 km (930 and 1,060 mi) away, respectively—where office buildings swayed with the tremor.
Corona-viruses are a group of viruses that cause diseases in mammals and birds. In humans, the viruses cause respiratory infections – including the common cold – which are typically mild. Rarer forms such as SARS, MERS and the novel corona-virus causing the 2019–20 Covid-19 Virus outbreak can be lethal. In cows and pigs corona-viruses cause diarrhea. In chickens they cause an upper respiratory disease. There are no vaccines or antiviral drugs that are approved for prevention or treatment.
