2021 Eruption Of La Soufrière
La Soufrière, a stratovolcano on the Caribbean island of Saint Vincent in Saint Vincent and the Grenadines, began an effusive eruption on 27 December 2020. On 9 April 2021 there was an explosive eruption, and the volcano "continued to erupt explosively" over the following days, with pyroclastic flows. The activity pattern of the eruption was comparable to that of the event that occurred in 1902, which had a Volcanic Explosivity Index (VEI) of 4. The volcano is known to have erupted 23 times in the last 4,000 years, and had been dormant since 1979. Evacuation of the inhabitants of the island began when the explosive eruptions started. Many countries, including islands in the region, and organisations provided relief and support. Services such as electricity and water were severely affected. Emitted ash and sulfur dioxide gas affected the population. The COVID-19 pandemic made evacuation more difficult, requiring usual COVID-19 precautions to avoid outbreaks. Effusive ph ...

La Soufrière (volcano)
La Soufrière or Soufrière Saint Vincent () is an active stratovolcano on the Caribbean island of Saint Vincent in Saint Vincent and the Grenadines. It is the highest peak in Saint Vincent, and has had five recorded explosive eruptions since 1718. The latest eruptive activity began on 27 December 2020 with the slow extrusion of a dome of lava, and culminated in a series of explosive events between 9 and 22 April 2021.

Volcanologist
A volcanologist, or volcano scientist, is a geologist who focuses on understanding the formation and eruptive activity of volcanoes. Volcanologists frequently visit volcanoes, sometimes active ones, to observe and monitor volcanic eruptions, collect eruptive products including tephra (such as ash or pumice), rock and lava samples. One major focus of inquiry in recent times is the prediction of eruptions to alleviate the impact on surrounding populations and monitor natural hazards associated with volcanic activity. Geologists who research volcanic materials that make up the solid Earth are referred to as igneous petrologists. Etymology The word ''volcanologist'' (or ''vulcanologist'') is derived from the English volcanology (volcano + -logy), which was derived from the French volcanologie (or vulcanologie), which was further derived from the French word volcan (volcano), which was even further derived from Vulcanus, the Latin name of the Roman god of fire and metalworking.

Coordinated Universal Time
Coordinated Universal Time or UTC is the primary time standard by which the world regulates clocks and time. It is within about one second of mean solar time (such as UT1) at 0° longitude (at the IERS Reference Meridian as the currently used prime meridian) and is not adjusted for daylight saving time. It is effectively a successor to Greenwich Mean Time (GMT). The coordination of time and frequency transmissions around the world began on 1 January 1960. UTC was first officially adopted as CCIR Recommendation 374, ''Standard-Frequency and Time-Signal Emissions'', in 1963, but the official abbreviation of UTC and the official English name of Coordinated Universal Time (along with the French equivalent) were not adopted until 1967. The system has been adjusted several times, including a brief period during which the time-coordination radio signals broadcast both UTC and "Stepped Atomic Time (SAT)" before a new UTC was adopted in 1970 and implemented in 1972. This change also a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atlantic Time Zone
The Atlantic Time Zone is a geographical region that keeps standard time—called Atlantic Standard Time (AST)—by subtracting four hours from Coordinated Universal Time ( UTC), resulting in UTC−04:00. AST is observed in parts of North America and some Caribbean islands. During part of the year, some portions of the zone observe daylight saving time, referred to as Atlantic Daylight Time (ADT), by moving their clocks forward one hour to result in UTC−03:00. The clock time in this zone is based on the mean solar time of the 60th meridian west of the Greenwich Observatory. In Canada, the provinces of New Brunswick, Nova Scotia, and Prince Edward Island are in this zone, though legally they calculate time specifically as an offset of four hours from Greenwich Mean Time (GMT–4) rather than from UTC. Small portions of Quebec (eastern Côte-Nord and the Magdalen Islands) also observe Atlantic Time. Officially, the entirety of Newfoundland and Labrador observes Newfoundland Stand ...

Chateaubelair
Chateaubelair is a large fishing village on the Leeward (west) coast of the Caribbean island of Saint Vincent, the main island of Saint Vincent and the Grenadines. It is located just south of the volcano of Soufrière. Commonly referred to as just " Chateau''", it is the focus and the largest community in the North Leeward constituency of St. Vincent, and the fourth largest town in the country. Local attractions include Trinity Falls, Dark View Falls, and rock carvings which are an archaeological find and are believed to have been left by Kalinago. Many activities are available year-round, spearfishing is now illegal in all of the Grenadines, more common to the Caribbean as a whole, dominoes, basketball, soccer and cricket. The local economy is mainly supported by farming. Chateaubelair is not a developed area, and though it has much appeal for tourists, it does not have much support. However, anyone looking to experience true Caribbean culture instead of a manufactured offe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Volcano Tectonic Earthquake
A volcano tectonic earthquake is caused by the movement of magma beneath the surface of the Earth. The movement results in pressure changes where the rock around the magma has experienced stress. At some point, this stress can cause the rock to break or move. This seismic activity is used by scientists to monitor volcanoes. The earthquakes may also be related to dike intrusion or occur as earthquake swarms. Cause of volcano tectonic earthquakes One possible scenario resulting in a possible volcano tectonic earthquake is tectonic subduction zones. The compression of plates at these subduction zones forces the magma beneath them to move. Magma can not move through the newly compressed crust in as easily a manner. This means it tends to pool in magma chambers beneath the surface and between the converging tectonic plates. Many of the famous and most well known volcanoes fall on this line, including the Ring of Fire. As the plates move, magma underground may be forced in and out ...

Low Frequency Earthquake
A slow earthquake is a discontinuous, earthquake-like event that releases energy over a period of hours to months, rather than the seconds to minutes characteristic of a typical earthquake. First detected using long term strain measurements, most slow earthquakes now appear to be accompanied by fluid flow and related tremor, which can be detected and approximately located using seismometer data filtered appropriately (typically in the 1–5 Hz band). That is, they are quiet compared to a regular earthquake, but not "silent" as described in the past. Slow earthquakes should not be confused with tsunami earthquakes, in which relatively slow rupture velocity produces tsunami out of proportion to the triggering earthquake. In a tsunami earthquake, the rupture propagates along the fault more slowly than usual, but the energy release occurs on a similar timescale to other earthquakes. __TOC__ Causes Earthquakes occur as a consequence of gradual stress increases in a region, an ...

Hydrogen Sulfide
Hydrogen sulfide is a chemical compound with the formula . It is a colorless chalcogen-hydride gas, and is poisonous, corrosive, and flammable, with trace amounts in ambient atmosphere having a characteristic foul odor of rotten eggs. The underground mine gas term for foul-smelling hydrogen sulfide-rich gas mixtures is ''stinkdamp''. Swedish chemist Carl Wilhelm Scheele is credited with having discovered the chemical composition of purified hydrogen sulfide in 1777. The British English spelling of this compound is hydrogen sulphide, a spelling no longer recommended by the Royal Society of Chemistry or the International Union of Pure and Applied Chemistry. Hydrogen sulfide is toxic to humans and most other animals by inhibiting cellular respiration in a manner similar to hydrogen cyanide. When it is inhaled or it or its salts are ingested in high amounts, damage to organs occurs rapidly with symptoms ranging from breathing difficulties to convulsions and death. Despite this, the ...
