Hurricane Georges was a powerful and long-lived Cape Verde-type Category 4 hurricane which caused severe destruction as it traversed the Caribbean and Gulf of Mexico in September 1998, making seven landfalls along its path.
 Georges was the seventh tropical storm, fourth hurricane, and second major hurricane of the 1998 Atlantic hurricane season.
 It became the second most destructive storm of the season after Hurricane Mitch, the costliest Atlantic hurricane since Hurricane Andrew in 1992, and the deadliest since Hurricane Gordon in 1994.
 Georges killed 604 people, mainly on the island of Hispaniola, and caused extensive damage resulting at just under $10 billion (1998 US dollars, equivalent to $  billion in 2016 ) in damages mostly in St. Kitts and Nevis, Puerto Rico and Hispaniola.
The 1995 bombings in France were carried out by the Armed Islamic Group (GIA), who were broadening the Algerian Civil War to France.
 In total, these attacks killed eight and injured more than 100 people.
 The assassination of Abdelbaki Sahraoui, a co-founder of the Islamic Salvation Front (FIS) who opposed attacks in France, was a prelude of this extension of the Islamists' terrorist campaign to France.
The 29 October 2005 Delhi bombings occurred on 29 October 2005 in Delhi, India, killing 62 people and injuring at least 210 others in three explosions.
 The bombings came only two days before the important festival of Diwali, which is celebrated by Hindus, Sikhs, and Jains.
 The bombs were triggered in two markets in central and south Delhi and in a bus in the Govindpuri area in the south of the city.
 Indian investigators believe the Kashmir separatist/ Islamic terrorist group Lashkar-e-Taiba was behind the attacks.
The 2008 Mumbai attacks were a group of terrorist attacks that took place in November 2008, when 10 members of Lashkar-e-Taiba, an Islamic terrorist organisation based in Pakistan, carried out a series of 12 coordinated shooting and bombing attacks lasting four days across Mumbai.
 The attacks, which drew widespread global condemnation, began on Wednesday, 26 November and lasted until Saturday, 29 November 2008, killing 164 people and wounding at least 308.
During the September 11 attacks, 2,996 people were killed (including 19 terrorists) and more than 6,000 others wounded.
 These immediate deaths included 265 on the four planes (including the terrorists), 2,606 in the World Trade Center and in the surrounding area, and 125 at the Pentagon.
 The attacks of September 11, 2001, were the deadliest terrorist act in world history and the most devastating foreign attack on American soil since the attack on Pearl Harbor on December 7, 1941.

The 2014 California wildfire season saw several notable wildfires ignited in the state of California, especially during the month of May, when multiple fires were ablaze concurrently in Southern California, and during September, when several massive wildfires were burning in Northern California.
 In the context of the 2012–15 North American drought (especially the 2011–15 California drought), as well as powerful Santa Ana winds, weather conditions were ideal for wildfires.
 The season began unusually early when a wildfire ignited on January 1, followed by 6 more fires igniting later within the same month.
 During a heat wave and dry Santa Ana conditions in May 2014, multiple wildfires broke out simultaneously in San Diego County, along with several other wildfires elsewhere in California.
 By mid-May, fire officials said they had already dealt with 1,400 wildfires in California in 2014 - twice the normal amount for that time of year - and a spokesman for CAL FIRE described the conditions as "unprecedented."
 The May 2014 San Diego County wildfires were estimated to have caused at least $60 million (2014 USD) in damage.
 In late June to early August, another group of wildfires ignited across the state, some of which reached over twenty thousand acres in size.
 In mid-September, the largest group of wildfires erupted, with some wildfires becoming larger than 50,000 acres in size.
 In early September 2014, the Happy Complex Fire became the largest wildfire of the season, eventually topping out at 135369 acres in size on September 27.
 On October 8, an aerial tanker crashed during a firefighting effort at the Dog Rock Fire, which killed the pilot and sparked a small wildfire.
 From late September to late October, the latest flare-up of major wildfires were extinguished by cooler weather and precipitation.
 From December 10–13, a powerful winter storm extinguished the remaining wildfires that were present.
 In mid-December through late December, several more small wildfires sparked, but they were all extinguished by December 31.
 A total of 5,620 wildfires ignited throughout the year, which burned at least 631434 acres of land.
 The wildfires caused a total of 146 injuries and 2 fatalities, in addition to causing at least $184.02 million (2014 USD) in damage.
Since the September 11 attacks, the United States government has carried out drone strikes in Pakistan (see drone strikes in Pakistan), Yemen (see drone strikes in Yemen), Somalia, Afghanistan, and Libya.
The 1945 Atlantic hurricane season produced multiple landfalling tropical cyclones.
 It officially began on June 16 and lasted until October 31, dates delimiting the period when a majority of storms were perceived to form in the Atlantic Ocean.
 A total of 11 systems were documented, including a late-season cyclone retroactively added a decade later.
 Five of the eleven systems intensified into hurricanes, and two further attained their peaks as major hurricanes.
 Activity began with the formation of a tropical storm in the Caribbean on June 20, which then made landfalls in Florida and North Carolina at hurricane intensity, causing one death and at least $75,000 in damage.
 In late August, a Category 3 hurricane on the modern-day Saffir–Simpson hurricane wind scale struck the Texas coastline, with 3 deaths and $20.1 million in damage.
 The most powerful hurricane of the season, reaching Category 4 intensity, wrought severe damage throughout the Bahamas and East Coast of the United States, namely Florida, in mid-September; 26 people were killed and damage reached $60 million.
 A hurricane moved ashore the coastline of Belize in early October, causing one death, while the final cyclone of the year resulted in 5 deaths and $2 million in damage across Cuba and the Bahamas two weeks later.
 Overall, 36 people were killed and damage reached at least $82.85 million.
The September 11 attacks (also referred to as 9/11) were a series of four coordinated terrorist attacks by the Islamic terrorist group al-Qaeda on the United States on the morning of Tuesday, September 11, 2001.
 The attacks killed 2,996 people, injured over 6,000 others, and caused at least $10 billion in infrastructure and property damage.

The combination of topographic and climatic factors in the Tulsa area have frequently caused major flash flooding, especially near streams that normally drain the area.
 The city was founded atop a bluff on the Arkansas River.
 Thus, elevation protected most of the inhabitants and their possessions from damage when the river flooded.
 However, by the turn of the 20th Century the population growth had moved closer to the river, and the flatlands west of the Arkansas had begun to develop as well.
 The floods typically caused widespread property damage and sometimes death.
 By the 1920s, seasonal floods of the Arkansas began to cause serious damage and loss of life.
 Since its founding, city leaders had responded to such events by simply rebuilding and replacing the property that had been destroyed "in situ".
 Not until 1970 did the city government begin developing strategies to mitigate floods or at least minimize property damage and prevent loss of life.
 This article describes some of the more notable floods in Tulsa, then the mitigation and control strategies that evolved from them.
