Lockdown
A lockdown () is a restriction policy for people, community or a country to stay where they are, usually due to specific risks that could possibly harm the people if they move and interact freely. The term is used for a prison protocol that usually prevents people, information or objects from leaving an area. The protocol can usually only be initiated by someone in a position of authority. A lockdown can also be used to protect people inside a facility or, for example, a computing system, from a threat or other external event. In buildings doors leading outside are usually locked so that no person may enter or exit. Types Lockdowns may be adopted as a preventative measure or in response to a crisis as an emergency measure. Preventive lockdown A preventive lockdown is a preemptive action plan implemented to address an unusual scenario or a weakness in system to preempt any danger to ensure the safety and security of people, organisation and system.

2020 Coronavirus Lockdown In India
On the evening of 24 March 2020, the Government of India ordered a nationwide lockdown for 21days, limiting the movement of the entire 1.38billion (138 crores) population of India as a preventive measure against the COVID-19 pandemic in India. It was ordered after a 14-hour voluntary public curfew on 22March, followed by enforcement of a series of regulations in COVID-19 affected countries. The lockdown was placed when the number of confirmed positive coronavirus cases in India was approximately 500. Upon its announcement, a mass movement of people across the country was described as the largest since the partition of India in 1947. Observers stated that the lockdown had slowed the growth rate of the pandemic by 6April to a rate of doubling every six days, and by 18April, to a rate of doubling every eight days. As the end of the first lockdown period approached, state governments and other advisory committees recommended extending the lockdown. The governments of Odisha and Pun ...

COVID-19 Community Quarantines In The Philippines
COVID-19 community quarantines in the Philippines were a series of stay-at-home orders and '' cordon sanitaire'' measures that were implemented by the government of the Philippines through its Inter-Agency Task Force for the Management of Emerging Infectious Diseases (IATF-EID). As of November 2021, under the original classification system that was enacted in 2020, there were four main quarantine tiers. In Metro Manila there is now an alert level system (ALS) which has been introduced in September 2021 and it is already in place. As of November 2021, all regions of the country have been covered by the ALS system, which has become the national standard. In the original classification system, the strictest community quarantines is the "enhanced community quarantine" (ECQ), which effectively is a total lockdown. According to the ALS, there are five tiers of alert level, with alert level 1 being the most lenient and alert level 5 being the most strict. Background As a result o ...

COVID-19 Pandemic
The COVID-19 pandemic (also known as the coronavirus pandemic and COVID pandemic), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), began with an disease outbreak, outbreak of COVID-19 in Wuhan, China, in December 2019. Soon after, it spread to other areas of Asia, and COVID-19 pandemic by country and territory, then worldwide in early 2020. The World Health Organization (WHO) declared the outbreak a public health emergency of international concern (PHEIC) on 30 January 2020, and assessed the outbreak as having become a pandemic on 11 March. COVID-19 symptoms range from asymptomatic to deadly, but most commonly include fever, sore throat, nocturnal cough, and fatigue. Transmission of COVID-19, Transmission of the virus is often airborne transmission, through airborne particles. Mutations have variants of SARS-CoV-2, produced many strains (variants) with varying degrees of infectivity and virulence. COVID-19 vaccines were developed rapidly and deplo ...

Quarantine
A quarantine is a restriction on the movement of people, animals, and goods which is intended to prevent the spread of disease or pests. It is often used in connection to disease and illness, preventing the movement of those who may have been exposed to a communicable disease, yet do not have a confirmed medical diagnosis. It is distinct from medical isolation, in which those confirmed to be infected with a communicable disease are isolated from the healthy population. The concept of quarantine has been known since biblical times, and is known to have been practised through history in various places. Notable quarantines in modern history include the village of Eyam in 1665 during the bubonic plague outbreak in England; East Samoa during the 1918 flu pandemic; the Diphtheria outbreak during the 1925 serum run to Nome, the 1972 Yugoslav smallpox outbreak, the SARS pandemic, the Ebola pandemic and extensive quarantines applied throughout the world during the COVID-19 pande ...

Prison Riots
A prison riot is an act of concerted defiance or disorder by a group of prisoners against the prison administrators, prison officers, or other groups of prisoners. Academic studies of prison riots emphasize a connection between prison conditions (such as prison overcrowding) and riots, or discuss the dynamics of the modern prison riot. In addition, a large proportion of academic studies concentrate on specific cases of prison riots. Other recent research analyzes and examines prison strikes and reports of contention with inmate workers. Prison conditions In the late 20th century, the analyses and conclusions presented to account for prison disturbances and riots began to shift and change based upon new studies and research. Initially, prison riots were considered irrational actions on the behalf of the prisoners. Nevertheless, there has been a shift in the form of explanation as external conditions like overcrowding are promoted by authorities as possible sources of causation.E ...

Power Failure
A power outage, also called a blackout, a power failure, a power blackout, a power loss, a power cut, or a power out is the complete loss of the electrical power network supply to an end user. There are many causes of power failures in an electricity network. Examples of these causes include faults at power stations, damage to electric transmission lines, substations or other parts of the distribution system, a short circuit, cascading failure, fuse or circuit breaker operation. Power failures are particularly critical at sites where the environment and public safety are at risk. Institutions such as hospitals, sewage treatment plants, and mines will usually have backup power sources such as standby generators, which will automatically start up when electrical power is lost. Other critical systems, such as telecommunication, are also required to have emergency power. The battery room of a telephone exchange usually has arrays of lead–acid batteries for backup and ...

Earthquake
An earthquakealso called a quake, tremor, or tembloris the shaking of the Earth's surface resulting from a sudden release of energy in the lithosphere that creates seismic waves. Earthquakes can range in intensity, from those so weak they cannot be felt, to those violent enough to propel objects and people into the air, damage critical infrastructure, and wreak destruction across entire cities. The seismic activity of an area is the frequency, type, and size of earthquakes experienced over a particular time. The seismicity at a particular location in the Earth is the average rate of seismic energy release per unit volume. In its most general sense, the word ''earthquake'' is used to describe any seismic event that generates seismic waves. Earthquakes can occur naturally or be induced by human activities, such as mining, fracking, and nuclear weapons testing. The initial point of rupture is called the hypocenter or focus, while the ground level directly above it is the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flooding
A flood is an overflow of water ( or rarely other fluids) that submerges land that is usually dry. In the sense of "flowing water", the word may also be applied to the inflow of the tide. Floods are of significant concern in agriculture, civil engineering and public health. Human changes to the environment often increase the intensity and frequency of flooding. Examples for human changes are land use changes such as deforestation and removal of wetlands, changes in waterway course or flood controls such as with levees. Global environmental issues also influence causes of floods, namely climate change which causes an intensification of the water cycle and sea level rise. For example, climate change makes extreme weather events more frequent and stronger. This leads to more intense floods and increased flood risk. Natural types of floods include river flooding, groundwater flooding coastal flooding and urban flooding sometimes known as flash flooding. Tidal flooding may inclu ...

Columbine High School Massacre
A school shooting and attempted bombing occurred on April 20, 1999, at Columbine High School in Columbine, Colorado, United States. The perpetrators, twelfth-grade students Eric Harris and Dylan Klebold, murdered 13 students and one teacher; ten were killed in the school library, where Harris and Klebold subsequently died by suicide. Twenty additional people were injured by gunshots and gunfire was exchanged several times with law enforcement with neither side being struck. Another three people were injured trying to escape. The Columbine massacre was the deadliest mass shooting at a K-12 school in US history until December 2012. It is still considered one of the most infamous massacres in the US for inspiring many other school shootings and bombings; the word "Columbine" has since become a byword for modern school shootings. , Columbine is still both the deadliest mass shooting and school shooting in Colorado, and one of the deadliest mass shootings in the United States. ...

Fire
Fire is the rapid oxidation of a fuel in the exothermic chemical process of combustion, releasing heat, light, and various reaction Product (chemistry), products. Flames, the most visible portion of the fire, are produced in the combustion reaction when the fuel reaches its ignition point temperature. Flames from hydrocarbon fuels consist primarily of carbon dioxide, water vapor, oxygen, and nitrogen. If hot enough, the gases may become ionized to produce Plasma (physics), plasma. The color and Intensity (heat transfer), intensity of the flame depend on the type of fuel and composition of the surrounding gases. Fire, in its most common form, has the potential to result in conflagration, which can lead to permanent physical damage. It directly impacts land-based ecological systems worldwide. The positive effects of fire include stimulating plant growth and maintaining ecological balance. Its negative effects include hazards to life and property, atmospheric pollution, and water ...

Bomb Threat
A bomb threat or bomb scare is a threat, usually verbal or written, to detonate an explosive or incendiary device to cause property damage, death, injuries, and/or incite fear, whether or not such a device actually exists. History Bomb threats were used to incite fear and violence during the American Civil Rights Movement, during which leader of the movement Martin Luther King Jr. received multiple bomb threats during public addresses, and schools forced to integrate faced strong opposition, resulting in 43 bomb threats against Central High School in Arkansas being broadcast on TV and the radio. Motivations Supposed motives for bomb threats include: "humor, self assertion, anger, manipulation, aggression, hate and devaluation, omnipotence, fantasy, and psychotic distortion, ideology, retaliation," and creating chaos. Many of the motives based on personal emotion are speculative. Bomb threats that aren’t intended to be pranks are often made as parts of other crimes, such as ...
