According to volcanologists, this eruption was triggered by tectonic spreading of the Kivu rift causing the ground to fracture and allow lava to flow from ground fissures out of the crater lava lake and possibly from a deeper conduit nearer Goma. At the time of writing, scientists are concerned that the continuing high level of seismic activity indi- cates that the tectonic rifting may be gradually continuing. Scientists agree that volcano monitoring and contingency planning are essential for forecasting and responding to fu- ture trends. The relatively small loss of life in the January 2002 eruption (less than 100 deaths in a population of 500,000) was remarkable, and psychological stress was reportedly the main health consequence in the aftermath of the eruption. -
Volcanic Gases and Aerosols Guidelines Introduction
IVHHN Gas Guidelines www.ivhhn.org/gas/guidelines.html Volcanic Gases and Aerosols Guidelines The following pages contain information relating to the health hazards of gases and aerosols typically emitted during volcanic activity. Each section outlines the properties of the emission; its impacts on health; international guidelines for concentrations; and examples of concentrations and effects in volcanic contexts, including casualties. Before looking at the emissions data, we recommend that you read the general introduction to volcanic gases and aerosols first. A glossary to some of the terms used in the explanations and guidelines is also provided at the end of this document. Introduction An introduction to the aims and purpose of the Gas and Aerosol Guidelines is given here, as well as further information on international guideline levels and the units used in the website. A brief review of safety procedures currently implemented by volcanologists and volcano observatories is also provided. General Introduction Gas and aerosol hazards are associated with all volcanic activity, from diffuse soil gas emissions to 2- plinian eruptions. The volcanic emissions of most concern are SO2, HF, sulphate (SO4 ), CO2, HCl and H2S, although, there are other volcanic volatile species that may have human health implications, including mercury and other metals. Since 1900, there have been at least 62 serious volcanic-gas related incidents. Of these, the gas-outburst at Lake Nyos in 1986 was the most disastrous, causing 1746 deaths, >845 injuries and the evacuation of 4430 people. Other volcanic-gas related incidents have been responsible for more than 280 deaths and 1120 injuries, and contributed to the evacuation or ill health of >53,700 people (Witham, in review). -
Information on Natural Disasters Part- I Introduction
Information on Natural Disasters Part- I Introduction Astrology is the one that gave us the word ‘disaster’. Many believe that when the stars and planets are in malevolent position in our natal charts bad events or bad things would happen. Everyone one of us loves to avoid such bad things or disasters. The disaster is the impact of both natural and man-made events that influence our life and environment that surrounds us. Now as a general concept in academic circles, the disaster is a consequence of vulnerability and risk. The time often demands for appropriate reaction to face vulnerability and risk. The vulnerability is more in densely populated areas where if, a bad event strikes leads to greater damage, loss of life and is called as disaster. In other sparely populated area the bad event may only be a risk or hazard. Developing countries suffer the greatest costs when a disaster hits – more than 95 percent of all deaths caused by disasters occur in developing countries, and losses due to natural disasters are 20 times greater as a percentage of GDP in developing countries than in industrialized countries. A disaster can leads to financial, environmental, or human losses. The resulting loss depends on the capacity of the population to support or resist the disaster. The term natural has consequently been disputed because the events simply are not hazards or disasters without human involvement. Types of disasters Any disaster can be classified either as ‘Natural’ or ‘man-made’. The most common natural disasters that are known to the man kind are hailstorms, thunderstorm, very heavy snowfall, very heavy rainfalls, squalls, gale force winds, cyclones, heat and cold waves, earthquakes, volcanic eruptions, floods, and droughts which cause loss to property and life. -

The effects of volcanic gases on life 12 13 6 may be direct, such as asphyxiation, respiratory diseases and skin burns; or indirect, e.g. regional 14 7 famine caused by the cooling that results from the presence of sulfate aerosols injected into the 15 16 8 stratosphere during explosive eruptions. Although accounting for fewer fatalities overall than some 17 18 9 other forms of volcanic hazards, history has shown that volcanic gases are implicated frequently in 1910 small-scale fatal events in diverse volcanic and geothermal regions. In order to mitigate risks due 20 2111 to volcanic gases, we must identify the challenges. The first relates to the difficulty of monitoring 22 2312 and hazard communication: gas concentrations may be elevated over large areas and may change 2413 rapidly with time. Developing alert and early warning systems that will be communicated in a timely 25 2614 fashion to the population is logistically difficult. The second challenge focuses on education and 27 2815 understanding risk. An effective response to warnings requires an educated population and a 2916 balanced weighing of conflicting cultural beliefs or economic interests with risk. -

Tech I semester (JNTU-R13) smartworlD.asia Smartzworld.com 1 jntuworldupdates.org Smartworld.asia Specworld.in UNIT-1 Environmental hazard' is the state of events which has the potential to threaten the surrounding natural environment and adversely affect people's health. This term incorporates topics like pollution and natural disasters such as storms and earthquakes. Hazards can be categorized in five types: 1. Chemical 2. Physical 3. Mechanical 4. Biological 5. Psychosocial What are chemical hazards and toxic substances? Chemical hazards and toxic substances pose a wide range of health hazards (such as irritation, sensitization, and carcinogenicity) and physical hazards (such as flammability, corrosion, and reactivity). This page provides basic information about chemical hazards and toxic substances in the workplace. While not all hazards associated with every chemical and toxic substance are addressed here, we do provide relevant links to other pages with additional information about hazards and methods to control exposure in the workplace. A natural disaster is a major adverse event resulting from natural processes of the Earth; examples includesmartworlD.asia floods, volcanic eruptions, earthquakes, tsunamis, and other geologic processes. A natural disaster can cause loss of life or property damage, and typically leaves some economic damage in its wake, the severity of which depends on the affected population's resilience, or ability to recover.[1] An adverse event will not rise to the level of a disaster if it occurs in an area without vulnerable population.[2][3][4] In a vulnerable area, however, such as San Francisco, an earthquake can have disastrous consequences and leave lasting damage, requiring years to repair. -
Artifacts and Natural Disasters in Nigeria: the Riverine Experiences
International Journal of Social Sciences and Management Research Vol. 4 No. 8 2018 ISSN: 2545-5303 www.iiardpub.org Artifacts and Natural Disasters in Nigeria: The Riverine Experiences Eluozo Collins Department of curriculum and Instructional Technology (Science Education Option) Faculty of Education Ignatius Ajuru University of Education, Port Harcourt, Nigeria [email protected], [email protected] Abstract Nigeria is a country endowed with enormous natural resources located in the Western Sub- Sahara of Africa. The country is conceived to have existed before 1100 years before Christ. The country Nigeria and its environs is characterized by multiethnic diversity and diverse history of religious beliefs. The country was cohered by the British missionaries and it was granted independence in 1960 and a republic in 1963. Nigeria’s land mass is featured by dry, costal and swampy ecosystem. According to the holy bible, God used disasters to punish and cleanse the planet earth due to man’s disobedience and till date mankind has not found solutions to various types of artifact and natural disasters that have besieged the planet. How these disasters erupts, unlash mayhems and devastate the earth was the focal point of the study. The paper discussed lithosphere disasters, artifacts, atmospheric and hydrosphere disasters, there various impacts on the riverine communities and disasters benefits as well losses. The paper concluded with recommendations that could foster purposive solutions that can help in containing these catastrophes against mankind. Keywords: Nigeria, Disasters, Bible.

Detecting Gas-Rich Hydrothermal Vents in Ngozi Crater Lake Using
www.nature.com/scientificreports OPEN Detecting gas-rich hydrothermal vents in Ngozi Crater Lake using integrated exploration tools Received: 16 May 2019 Egbert Jolie1,2,3 Accepted: 7 August 2019 Gas-rich hydrothermal vents in crater lakes might pose an acute danger to people living nearby due Published: xx xx xxxx to the risk of limnic eruptions as a result of gas accumulation in the water column. This phenomenon has been reported from several incidents, e.g., the catastrophic Lake Nyos limnic eruption. CO2 accumulation has been determined from a variety of lakes worldwide, which does not always evolve in the same way as in Lake Nyos and consequently requires a site-specifc hazard assessment. This paper discusses the current state of Lake Ngozi in Tanzania and presents an efcient approach how major gas-rich hydrothermal feed zones can be identifed based on a multi-disciplinary concept. The concept combines bathymetry, thermal mapping of the lake foor and gas emission studies on the water surface. The approach is fully transferable to other volcanic lakes, and results will help to identify high-risk areas and develop suitable monitoring and risk mitigation measures. Due to the absence of a chemical and thermal stratifcation of Lake Ngozi the risk of limnic eruptions is rather unlikely at present, but an adapted monitoring concept is strongly advised as sudden CO2 input into the lake could occur as a result of changes in the magmatic system. Intense gas emissions at the geosphere-atmosphere interface is a common process in volcanically and tectoni- 1 cally active regions. -
Lake Nyos, a Multirisk and Vulnerability Appraisal
geosciences Article Lake Nyos, a Multirisk and Vulnerability Appraisal Mesmin Tchindjang ID Department of Geography, Faculty of Arts Letters and Social Sciences, Campus of Ngoa Ekellé, The University of Yaoundé 1, PO BOX 755 Yaoundé, Cameroon; [email protected] or [email protected]; Tel.: +237-699-85-59-26 or +237-679-30-88-15 Received: 13 July 2018; Accepted: 20 August 2018; Published: 21 August 2018 Abstract: Situated at the northern flank of the Oku Massif, Lake Nyos crater epitomizes landscape features originating from volcanic explosions during the Quaternary. The Cameroon Volcanic Line (CVL), to which it belongs, constitutes the most active volcanic region in Cameroon. In 1986, an outgas explosion occurred from beneath the lake and killed 1746 people in several neighbouring villages. The event influenced a radial area of 25 to 40 km wide, particularly in eastern and western direction. This was mainly due to: (1) the rugged nature of the landscape (fault fields), which enabled the heavier gas to follow valleys framed by faults corridors without affecting elevated areas; and (2) the seasonal dominating western wind direction, which channeled the gas along tectonic corridors and valleys. This paper assesses the geological risk and vulnerability in the Lake Nyos before and after several proposal to mitigate future outgas events. Remotely sensed data, together with GIS tools (topographic maps, aerial photographs), helped to determine and assess lineaments and associated risks. A critical grid combining severity and frequency analysis was used to assess the vulnerability of the local population. There is evidence that along the main fault directions (SW–NE), anthropogenic activities are most intensive and they may play an aggravating role for disasters. -
Carbon Dioxide - Wikipedia
5/20/2020 Carbon dioxide - Wikipedia Carbon dioxide Carbon dioxide (chemical formula CO2) is a colorless gas with Carbon dioxide a density about 60% higher than that of dry air. Carbon dioxide consists of a carbon atom covalently double bonded to two oxygen atoms. It occurs naturally in Earth's atmosphere as a trace gas. The current concentration is about 0.04% (412 ppm) by volume, having risen from pre-industrial levels of 280 ppm.[8] Natural sources include volcanoes, hot springs and geysers, and it is freed from carbonate rocks by dissolution in water and acids. Because carbon dioxide is soluble in water, it occurs naturally in groundwater, rivers and lakes, ice caps, glaciers and seawater. It is present in deposits of petroleum and natural gas. Carbon dioxide is odorless at normally encountered concentrations, but at high concentrations, it has a sharp and acidic odor.[1] At such Names concentrations it generates the taste of soda water in the Other names [9] mouth. Carbonic acid gas As the source of available carbon in the carbon cycle, atmospheric Carbonic anhydride carbon dioxide is the primary carbon source for life on Earth and Carbonic oxide its concentration in Earth's pre-industrial atmosphere since late Carbon oxide in the Precambrian has been regulated by photosynthetic organisms and geological phenomena.
