The 1902 eruption of Mount Pelée was a volcanic eruption on the island of Martinique in the Lesser Antilles Volcanic Arc of the eastern Caribbean, which was one of the deadliest eruptions in recorded history. Eruptive activity began on 23 April as a series of phreatic explosions from the summit of Mount Pelée. Within days, the vigor of the explosions exceeded anything witnessed since the island was settled by Europeans. The intensity then subsided for a few days until early May, when the explosions increased again. Lightning laced the eruption clouds and trade winds dumped ash on villages to the west. Heavy ash fall at times caused total darkness. Some of the afflicted residents panicked and headed for the perceived safety of larger settlements, especially Saint-Pierre, about 10 km (6.2 mi) south of Pelée's summit. Saint-Pierre received its first ash fall on 3 May.Mount Pelée remained relatively quiet until the afternoon of 5 May when a mudflow swept down a river on the southwest flank of the volcano, destroying a sugar mill. The massive flow buried about 150 people and generated a series of three tsunamis as it hit the sea. The tsunamis swept along the coast, damaging buildings and boats. The explosions resumed the night of 5 May. The following morning, parts of the eruption plume became incandescent, signifying that the character of the eruption had changed. The phreatic explosions had finally given way to magmatic explosions as magma reached the surface. The explosions continued through the next day and night.A brief lull was shattered by a tremendous explosion at about 8:00 a.m. on 8 May. A ground-hugging cloud of incandescent lava particles suspended by searing turbulent gases moved at hurricane speed down the southwest flank of the volcano, reaching Saint-Pierre at 8:02 a.m. Escape from the city was virtually impossible. Almost everyone within the city proper—about 28,000 people—died, burned or buried by falling masonry. The hot ash ignited a firestorm, fueled by smashed buildings and countless casks of rum. Only two people survived within the city, along with a few tens of people caught within the margins of the cloud. All survivors were badly burned.Explosive activity on 20 May resulted in another 2,000 deaths as rescuers, engineers and mariners brought supplies to the island. A powerful eruption on 30 August generated a pyroclastic flow that resulted in over 800 people killed. The eruption continued until October 1905.

The COVID-19 pandemic, also known as the coronavirus pandemic, is an ongoing global pandemic of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The novel virus was first identified in the Chinese city of Wuhan in December 2019; a lockdown in Wuhan and other cities in surrounding Hubei failed to contain the outbreak, and it quickly spread to other parts of mainland China and around the world. The World Health Organization (WHO) declared a Public Health Emergency of International Concern on 30 January 2020, and a pandemic on 11 March 2020. Multiple variants of the virus have emerged and become dominant in many countries since 2021, with the Alpha, Beta, Gamma, Delta and Omicron variants being the most virulent. As of 1 December 2021, more than 262 million cases and 5.21 million deaths have been confirmed, making the pandemic one of the deadliest in history. COVID-19 symptoms range from none to life-threatening. Severe illness is more likely in elderly patients and those with certain underlying medical conditions. Transmission of COVID-19 occurs when people breathe in air contaminated by droplets and small airborne particles. The risk of breathing these in is highest when people are in close proximity, but the virus can transmit over longer distances, particularly indoors and in poorly ventilated areas. Transmission can also occur, rarely, via contaminated surfaces or fluids. People remain contagious for up to 20 days, and can spread the virus even if they do not develop symptoms. Several vaccines have been approved and distributed in various countries, which have initiated mass vaccination campaigns since December 2020. Other recommended preventive measures include social distancing, wearing face masks in public, ventilation and air-filtering, covering one's mouth when sneezing or coughing, hand washing, disinfecting surfaces, and quarantining people who have been exposed or are symptomatic. Treatments focus on addressing symptoms, but work is underway to develop medications that inhibit the virus. Authorities worldwide have responded by implementing travel restrictions, lockdowns, business closures, workplace hazard controls, testing protocols, and systems for tracing contacts of the infected. The pandemic has resulted in severe social and economic disruption around the world, including the largest global recession since the Great Depression in the 1930s. It has led to widespread supply shortages exacerbated by panic buying, agricultural disruption, and food shortages. The resultant near-global sustained quarantine saw an unprecedented decrease in the emission of pollutants. Numerous educational institutions and public areas have been partially or fully closed, and many events have been cancelled or postponed. Misinformation has circulated through social media and mass media, and political tensions have been exacerbated. The pandemic has raised issues of racial and geographic discrimination, health equity, and the balance between public health imperatives and individual rights.
