What natural disasters happened in 2021?

Earthquake in Sulawesi: On Jan. 15, an M 6.2 earthquake struck the city of Majene on the west coast of Indonesia's Sulawesi island, killing more than 90 people and displacing 94,000.

Flood in Australia: Days of heavy rain pounded the Australian province of New South Wales at the end of March 2021, leading to a "once-in-a-hundred-year-flood".

Earthquake in Haiti: On Aug. 14, an M 7.2 earthquake, the biggest since 2010, struck Haiti. It killed more than 2000 people. At least 1,37.500 buildings were damaged or destroyed.

Volcanic eruption in Indonesia: Indonesia's Java Island experienced several days of heavy rain that left a heavy pool of water on the lava dome at the top of Mount Semeru. On Dec 4, the lava dome collapsed, unleashing the molten lava beneath in an explosive eruption that sent thousands of people fleeing the area.

What happened on the 26th April 1986 Ukrainian city of Chernobyl to make it suddenly uninhabitable?

Ukraine recently commemorated the 35th anniversary of the Chernobyl disaster, considered one of the world’s worst nuclear disasters. The disaster was the result of an explosion in the fourth reactor of the Chernobyl nuclear power station, in the former USSR, which led to radiation poisoning across Ukraine and neighbouring Belarus and Russia. The exact number of victims remains a subject of intense debate because the Soviet authorities kept most of the information about the disaster hidden. Hundreds of thousands of people were evacuated from the area around the disaster site, and the exclusion zone has now become a ghostly uninhabited region.

Ukrainian authorities say the area may not be fit for humans for 24,000 years, but the site has been attracting tourists in the recent years and Ukraine wants to make it a UNESCO World Heritage Site.

During the 35th year commemoration, Ukraine’s president Volodymyr Zelensky unveiled a new nuclear waste repository at Chernobyl, where the country could store its nuclear waste for the next 100 years. On the occasion, Ukrainian government also released a document claiming that the Soviet Union (which Ukraine was then part of) knew the Chernobyl nuclear plant was dangerous and covered up emergencies there even before the 1986 disaster.

What happened on April 226, 1986?

The Chernobyl nuclear power station was situated at the settlement of Pripyat, north of Kiev in Ukraine. Built in the late 1970s on the banks of the Pripyat River, Chernobyl had four reactors, each capable of producing 1,000 megawatts of electric power.

On the night of April 25, 1986, the reactor crew at Reactor No. 4 of experiment, which was found to be poorly designed during investigation. A series of mistakes, including the disabling of automatic shutdown mechanisms, led to the nuclear chain reaction going out of control. Reactor No. 4 exploded and caught fire on April 26, 1986, shattering the building and spewing large amounts of radioactive material from the graphite reactor core into the atmosphere, which soon spread across Ukraine, Belarus, Russia and many parts of Europe. Firefighters and helicopters attempted to put out a series of blazes at the plant, but to no avail

What happened after the explosion?

The Soviet authorities made the catastrophe worse by withholding information from the public on what had happened, even though they began an evacuation of the 30,000 inhabitants of Pripyat on April 27, 1986. The world learned of the disaster only after heightened radiation was detected in Sweden on April 28. The Swedish radiation monitoring stations, more than 800 miles to the northwest of Chernobyl, reported radiation levels 40% higher than normal. After first denying any accident, the Soviet finally acknowledged the disaster on April 28. About 600,000 emergency workers and state employees who became known as “liquidators” were dispatched with little or no protective gear to help clean up the aftermath of the disaster. The details of the incident and the victim numbers were shrouded in secrecy.

Soon after the disaster, radioactive debris were buried at some 800 temporary sites, albeit at great risk to workers. Eventually, more than 100,000 people were evacuated from the vicinity and an exclusion zone was established around the station. The exclusion zone is a 30-kilometre radius area around the nuclear power plant that was evacuated in the aftermath of the explosion. It was deemed unsafe for humans to live in for thousands of years.

How many people died as an immediate result of the accident?

Thirty-one plant workers and firemen died in the immediate aftermath of the disaster, mostly from acute radiation sickness. Thousands more later succumbed to radiation-related illnesses such as cancer, although the total death toll and long-term health effects remain a subject of intense debate.

Why is it considered one of the worst disasters?

Between 50 and 185 million curies of radioactive material escaped into the atmosphere. It’s estimated that the amount of radioactive material was 400 times more than the atom bomb dropped on Hiroshima and Nagasaki during World War II.

The radioactivity was spread over large parts of Europe, including Belarus, Russia, Ukraine, Scandinavian countries, France and Italy.

The United Nations Scientific Committee on the Effects of Atomic Radiation reported that more than 6,000 children and adolescents developed thyroid cancer after being exposed to radiation from the incident, although some experts have challenged that claim.

Scientists are still in the process of gauging the extent of the damage and starting to answer questions about the long-term legacy of radiation exposure on the power plant workers, the people in the nearby community, and even their family members born years later.

What is the status of this exclusion zone and the station?

  • No one is allowed to live in this exclusion zone. However, the Ukrainian government allows tourists and scientists to enter nearby areas and even the town of Pripyat for a limited period of time.
  • The highly radioactive reactor core was enclosed in a concrete-and-steel sarcophagus by the end of 1986. In November 2016, a massive metal dome was erected over the remains of the reactor to stop future leaks and ensure the safety of people for generations. Containment efforts and monitoring continue and cleanup is expected to last until at least 2065.
  • Regarding the other reactors of the station, Unit 2 was closed in 1991 after a fire and Unit 1 was shut down after 1996. Unit 3 of Chernobyl remained operational till 2000 when the power station was decommissioned.

What happened to the environment and animals after the accident?

Millions of acres of forest and farmland were contaminated, and in the subsequent years many livestock were born deformed. According to the International Atomic Energy Agency, mutations occurred in plants and animals after the explosion. Leaves changed shape and some animals were born with physical deformities. However, some animals are now returning in large numbers to the area. These animals include beavers, moose, wolves and wild boar, plus a wide variety of birds.

In 2011, which country was the worst hit by extreme drought that affected more than 13 million people across the Horn of Africa?

Somalia was worst hit by the extreme drought in 2011 that affected more than 13 million people across the Horn of Africa.

Tens of thousands of people fled their homes in search of food.

The UN declared the famine over in February 2012.

"While conditions in Somalia have improved in recent months, the country still has one of the highest rates of child malnutrition and infant mortality in the world," Ben Foot, from the charity Save the Children, said in a statement.

The UK government has said that at a conference it is hosting on Somalia's future next week it will set out policies on how to tackle the root cause of famine and contain the effects of drought.

The UK's International Development Secretary Justine Greening said Somalia's famine had been "one of the worst disasters of recent times,"

During more than 20 years of civil war, Somalia has seen clan-based warlords, rival politicians and Islamist militants battle for control - a situation that has allowed lawlessness to flourish.

Last September, a UN-backed government came to power, after eight years of transitional rule, bringing some stability to some areas.

The 2019-2020 bushfire season, killing or displacing three billion animals, in which country is now referred to as Black Summer?

Last summer's bushfires, which Prime Minister Scott Morrison has dubbed Australia's “black summer”, also killed 33 people and razed over 24 million hectares (59 million acres) in the country.

The fires ravaged more than 115,000 square kilometres (44,400 square miles) of drought-stricken bushland and forest across Australia in late 2019 and early 2020, killing more than 30 people and destroying thousands of homes.

It was the broadest and most prolonged bushfire season in modern Australian history, with scientists attributing the severity of the crisis to the impacts of climate change.

An earlier study in January estimated the fires had killed a billion animals in the hardest-hit eastern states of New South Wales and Victoria. But the new survey was the first to cover fire zones across the continent, said lead scientist Lily van Eeden, of the University of Sydney.

In 2010, which Caribbean country was hit by a high-magnitude earthquake, leaving at least 3, 00,000 people dead?

With approximately 3 million people affected, this earthquake was the most devastating natural disaster ever experienced in Haiti, the poorest country in the Western Hemisphere. Roughly 250,000 lives were lost and 300,000 people were injured. About 1.5 million individuals were forced to live in makeshift internally displaced person camps. As a result, the country faced the greatest humanitarian need in its history.

The earthquake registered a magnitude 7.0; that’s a high level of energy at the point of impact. Because it occurred at 6.2 miles below the surface, a shallow depth, its powerful energy had a devastating effect at ground level.

The epicenter of the quake was near to Port-au-Prince, the capital city, with more than 2 million people in the metropolitan area. Many of Port-au-Prince’s multi-story concrete buildings collapsed in a deadly heap because they were poorly constructed. There were no building codes enforced.
