Hurricanes, tropical storms, typhoons, and cyclones are all terms that describe a closed circulation system in the atmosphere consisting of strong winds and low pressure that rotate clockwise in the southern hemisphere and counter-clockwise in the northern hemisphere. Earthquakes are the result of a sudden break within the upper crust of the Earth that may also break the surface and cause the ground to vibrate. Tsunamis, usually caused by earthquakes, underwater explosions, landslides or volcanic eruptions under the ocean floor, are one of the deadliest natural disasters and can affect millions of people with waves that get bigger as they approach the coast. Floods occur when a body of water exceeds its capacity and overflows its channel or boundaries
A natural disaster occurs when a natural hazard affects a vulnerable population, leading to losses. The effects depend on a population's resilience to resist the hazard. Disasters only occur when hazards interact with vulnerability. While hazards exist naturally, it is human involvement that transforms them into disasters. For example, the 1906 San Francisco earthquake was a disaster due to its effects on the city, while unpopulated areas experience only hazards. Natural disasters disrupt communities and economies through damage and health impacts. Common natural disasters include earthquakes, floods, landslides, volcanic eruptions, wildfires and storms.
This ppt explained what is disaster and what are the common types of disaster. Then it explains the natural disasters like Flood, earthquake, tsunami, drought, landslides, heat & cold waves, thunderstorm etc....
The document discusses various types of natural disasters including earthquakes, tsunamis, floods, droughts, avalanches, landslides, cyclones, heat waves, and snowstorms. It explains that disaster management plans help communities reduce vulnerabilities and cope with disasters by focusing on prevention, mitigation, preparedness, response and recovery. Failure to have an adequate plan could result in damage, loss of life and revenue. The National Disaster Management Authority in India is responsible for disaster relief planning and capacity building.
A disaster is defined as a sudden event that severely disrupts a community's ability to function. Disasters can be caused by natural hazards like earthquakes, floods, hurricanes or drought. Natural disasters are classified as geophysical, hydrological, climatological, meteorological or biological based on their cause. Some key natural hazards covered are earthquakes, landslides, tsunamis, volcanic eruptions, avalanches, floods, extreme temperatures, drought, tropical storms and wildfires. Each hazard is described in terms of its causes, impacts and warning times. Mitigating and preparing for these various natural disasters poses challenges for emergency response.
Natural disasters include earthquakes, volcanic eruptions, cyclones, floods, droughts, tornadoes, and tsunamis. They are caused by shifts in the Earth's crust or severe weather events and can seriously disrupt communities. While often natural in origin, human activities may exacerbate some disasters by increasing their frequency or severity. Understanding the causes of different disasters may help mitigate their harmful impacts.
This document defines and provides brief descriptions of major natural disasters:
- Tsunami, flood, drought, storm, and earthquake are listed as major natural disasters.
- A flood is defined as an overflow of water that submerges land, usually caused by river, lake, or ocean overflow.
- An earthquake is defined as the shaking of the Earth's surface from a sudden release of energy, creating seismic waves that can destroy cities.
- A tsunami is defined as a series of waves caused by large volumes of water displacement, often from earthquakes or volcanic eruptions.
Natural disasters include earthquakes, volcanic eruptions, cyclones, floods, droughts, tornadoes, and tsunamis. Earthquakes result from the sudden movement of tectonic plates, causing shock waves that damage buildings and infrastructure. Volcanic eruptions eject lava and ash, destroying structures and harming health. Cyclones are rotating low-pressure systems that include hurricanes and typhoons, consisting of an eye, eye wall, and rain bands. Floods occur when bodies of water overflow their boundaries, submerging land. Droughts are prolonged periods of unusually dry weather that harm crops and reduce water supply. Tornadoes are violently rotating columns of air that extend from thunderstorms
Natural disasters are events caused by natural hazards like floods, earthquakes, volcanoes, etc. that lead to damage and losses. The impact of a natural hazard depends on the vulnerability of the affected population - their ability to resist the hazard. While hazards exist naturally, it is human settlement and involvement that transforms them into disasters. Several types of natural hazards are described in detail, including earthquakes, landslides, tsunamis, volcanoes, floods, and thunderstorms. Common causes and effects of each hazard are summarized.
This document discusses different types of natural disasters including hurricanes, floods, tornadoes, earthquakes, and tsunamis. It explains that hurricanes, tropical cyclones, and typhoons are different names for the same cyclonic storm system formed over oceans by evaporated water. Floods occur when a body of water exceeds its capacity and overflow. Tornadoes are rotating columns of air that can reach speeds over 300 mph. Earthquakes are caused by a sudden release of energy in the Earth's crust creating seismic waves. Tsunamis are a series of waves created by the rapid displacement of a large body of water.
Natural disasters are major adverse events caused by natural processes like earthquakes, floods, volcanic eruptions, and hurricanes. They often result in loss of life, property damage, and economic losses depending on a population's resilience. Common natural disasters include tsunamis caused by earthquakes under the sea, tornadoes which are violent rotating columns of air, volcanic eruptions which produce lava and ash, earthquakes caused by faults in the earth's crust, and floods from overflowing water. Forest fires, landslides, avalanches, and cyclones are also types of natural disasters, while epidemics can spread disease among human populations on a large scale.
Natural disasters are events that result from forces of nature such as hurricanes, floods, earthquakes, wildfires, and tornadoes. They occur in almost every part of the world and each region is prone to certain types of natural disasters. It is important to understand the natural disasters that affect your region so you can learn how to prepare for them. Common natural disasters include hurricanes, floods, tornadoes, earthquakes, and wildfires. Proper preparation like storing water, food, batteries, and first aid supplies can help keep people safe during a natural disaster.
Natural disasters are events caused by nature that result in widespread damage and loss of life. Examples include earthquakes, hurricanes, droughts and flooding. Asia experiences many natural disasters including hailstorms, hurricanes, landslides, thunderstorms, tornadoes, volcanic eruptions, droughts, earthquakes, wildfires, heat waves, floods, and tsunamis. Proper preparation and disaster response teams are important to help communities impacted by natural disasters.
Natural disasters such as earthquakes, tsunamis, hurricanes, floods and droughts can occur when natural hazards like seismic activity or extreme weather events negatively impact human lives and property. Earthquakes in particular generate seismic waves that are measured on the Richter scale and can trigger secondary events like tsunamis or landslides. Major historical earthquakes include the 2004 Indian Ocean earthquake and tsunami that killed over 200,000 people. Other natural hazards like hurricanes, tornadoes, volcanoes and floods can also lead to loss of life and damage when they interact with vulnerable human systems. Droughts cause problems like hunger, wildfires and disease through lack of water over an extended period.
This document provides a summary of different types of natural disasters that occur in India:
1. Floods are the most common natural disaster, with heavy monsoon rains causing rivers like the Brahmaputra to flood surrounding areas, killing thousands and displacing millions.
2. Other natural disasters include earthquakes, volcanoes, tsunamis, and hurricanes, which can cause massive damage through shaking, volcanic eruptions, huge waves, and strong winds respectively.
3. Disaster management plans aim to address a wide range of possible catastrophes by evacuating people, arranging housing and supplies, and containing the root causes of disasters when possible.
This document defines and describes different types of natural disasters. It discusses earthquakes, landslides, volcanic eruptions, floods, limnic eruptions, tsunamis, blizzards, hurricanes, droughts, hailstorms, heat waves, wildfires, health disasters, space disasters, avalanches, sinkholes, tornadoes, waterspouts, dusty devils and maelstorms.

Blind Spots in AI and Formulation Science Knowledge Pyramid (Updated Perspect...Ajaz Hussain
Ìý
This presentation delves into the systemic blind spots within pharmaceutical science and regulatory systems, emphasizing the significance of "inactive ingredients" and their influence on therapeutic equivalence. These blind spots, indicative of normalized systemic failures, go beyond mere chance occurrences and are ingrained deeply enough to compromise decision-making processes and erode trust.
Historical instances like the 1938 FD&C Act and the Generic Drug Scandals underscore how crisis-triggered reforms often fail to address the fundamental issues, perpetuating inefficiencies and hazards.
The narrative advocates a shift from reactive crisis management to proactive, adaptable systems prioritizing continuous enhancement. Key hurdles involve challenging outdated assumptions regarding bioavailability, inadequately funded research ventures, and the impact of vague language in regulatory frameworks.
The rise of large language models (LLMs) presents promising solutions, albeit with accompanying risks necessitating thorough validation and seamless integration.
Tackling these blind spots demands a holistic approach, embracing adaptive learning and a steadfast commitment to self-improvement. By nurturing curiosity, refining regulatory terminology, and judiciously harnessing new technologies, the pharmaceutical sector can progress towards better public health service delivery and ensure the safety, efficacy, and real-world impact of drug products.

2. WHAT ARE NATURAL DISASTERS ?
 It is an abnormal intensity of a natural agent .
 Its results include flood , earthquake , tsunami , drought etc. .
 A natural disaster can cause lose of life and damage property .
 It also disbalance the economics stability of a place .
 It also damages animal habitats .
4. Earthquake
ï‚´ An earthquake is what happens when two blocks of the earth suddenly slip
past one another .
ï‚´ The location below the earth's surface where the earthquake starts is
called the hypocenter.
ï‚´ The location directly above it on the surface of the earth is called the
epicenter.
ï‚´ Sometimes an earthquake has foreshocks.
5. Drought
ï‚´ A drought is a period of time when an area or region experiences below-
normal precipitation.
ï‚´ The lack of adequate precipitation, either rain or snow, can cause reduced
soil moisture or groundwater, diminished stream flow, crop damage, and a
general water shortage.
6. Flood
ï‚´ A flood is an overflow of water that submerges land that is usually dry.
ï‚´ Floods are an area of study in the discipline of hydrology.
ï‚´ They are the most common and widespread natural severe weather event.
ï‚´ Floods can look very different because flooding covers anything from a few
inches of water to several feet.
7. Tsunami
ï‚´ Tsunami are waves caused by sudden movement of the ocean surface due to
earthquakes, landslides on the sea floor, land slumping into the ocean, large
volcanic eruptions or meteorite impact in the ocean.
ï‚´
A tsunami is a very large and powerful wave.
ï‚´ There are two types of tsunami generation: Local tsunami and Far Field or
distant tsunami.
8. Cyclone
ï‚´ A cyclone is a system of winds rotating counterclockwise in the Northern
Hemisphere around a low pressure center.
ï‚´ The swirling air rises and cools, creating clouds and precipitation.
ï‚´ There are two types of cyclones: middle latitude (mid-latitude) cyclones and
tropical cyclones.
