2024 Wayanad Landslides
The 2024 Wayanad landslides were a series of landslides that occurred in Punjirimattom, Mundakkai, Wayanad, Mundakkai, Chooralmala, and Vellarimala villages in Meppadi panchayat, Vythiri taluk in Wayanad district, Kerala, India in the early hours of 30 August 2024. The landslides were caused by heavy rains that caused hillsides to collapse, destroying the areas below. The disaster was one of the deadliest in Kerala's history, with reports of over 336 fatalities, 397 injuries, and 78 people missing. Deforestation, seismic sensitivity, poor building construction, and global warming have been identified as possible causes for the landslides and fatalities. Many government agencies such as the armed forces, the National Disaster Response Force (NDRF), fire and rescue services, and forest and wildlife authorities, as well as volunteers, launched a large-scale rescue mission to search for survivors. Background Wayanad is at risk of landslides during monsoon seasons. Located in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Time In India
The Republic of India uses only one time zone (even though it spans across two geographical time zones) across the whole nation and all its territories, called Indian Standard Time (IST), which equates to UTC+05:30, i.e. five and a half hours ahead of Coordinated Universal Time (UTC). India does not currently observe daylight saving time (DST or summer time). The official time signal is given by the Time and Frequency Standards Laboratory. The IANA time zone database contains only one zone pertaining to India, namely ''Asia/Kolkata''. The date and time notation in India shows some peculiarities. Background History Ancient India The 4th century CE astronomical treatise Surya Siddhanta postulated a spherical earth. The book described the thousands years old customs of the prime meridian, or zero longitude, as passing through '' Avanti'', the ancient name for the historic city of Ujjain, and ''Rohitaka'', the ancient name for Rohtak (), a city near the Kurukshetra.

Rescue Workers Pass Through Mundakai And Churalmala Landslide Area In Wayanad
Rescue comprises responsive operations that usually involve the saving of life, or the urgent treatment of injuries after an accident or a dangerous situation. Tools used might include search and rescue dogs, mounted search and rescue horses, helicopters, the "jaws of life", and other hydraulic cutting and spreading tools used to extricate individuals from wrecked vehicles. Rescue operations are sometimes supported by rescue vehicles operated by rescue squads. Rescue is a potent theme in human psychology, both from mortal perils and moral perils, and is often treated in fiction, with the rescue of a damsel in distress being a notable trope. Psychoanalyst Sigmund Freud introduced the concept of "rescue fantasies" by men pursuing "fallen women" in his 1910 work "A Special Type of Choice of Object Made by Men"; Freud's insight into this aspect of male psychology might retain merit, though his proposed Oedipus complex used to frame this concept is no longer in ...

Monsoon
A monsoon () is traditionally a seasonal reversing wind accompanied by corresponding changes in precipitation but is now used to describe seasonal changes in atmospheric circulation and precipitation associated with annual latitudinal oscillation of the Intertropical Convergence Zone (ITCZ) between its limits to the north and south of the equator. Usually, the term monsoon is used to refer to the rainy phase of a seasonally changing pattern, although technically there is also a dry phase. The term is also sometimes used to describe locally heavy but short-term rains. The major monsoon systems of the world consist of the West African, Asia–Australian, the North American, and South American monsoons. The term was first used in English in British India and neighboring countries to refer to the big seasonal winds blowing from the Bay of Bengal and Arabian Sea in the southwest bringing heavy rainfall to the area.

Iruvanjippuzha
Iruvazhanjippuzha, or Iruvanjipuzha, is a major tributary of River Chaliyar and joining to Chaliyar at Koolimadu near Cheruvadi. Its major tributary is Chalippuzha, which joins with it about 3 km north of Thiruvambady town. Other tributaries are Muthappanpuzha (joining at Anakkampoyil), ulingappuzha (joining at Thiruvambadi) and Karamoola river (join at Mukkam). The famous Thusharagiri waterfall is in the Chalippuzha river. Every year thMalabar River Festivalhappens in this river, which is recognized as the biggest Kayak event in Asia.

Early Cretaceous
The Early Cretaceous ( geochronological name) or the Lower Cretaceous (chronostratigraphic name), is the earlier or lower of the two major divisions of the Cretaceous. It is usually considered to stretch from 145 Ma to 100.5 Ma. Geology Proposals for the exact age of the Barremian-Aptian boundary ranged from 126 to 117 Ma until recently (as of 2019), but based on drillholes in Svalbard the defining early Aptian Oceanic Anoxic Event 1a (OAE1a) was carbon isotope dated to 123.1±0.3 Ma, limiting the possible range for the boundary to c. 122–121 Ma. There is a possible link between this anoxic event and a series of Early Cretaceous large igneous provinces (LIP). The Ontong Java-Manihiki-Hikurangi large igneous province, emplaced in the South Pacific at c. 120 Ma, is by far the largest LIP in Earth's history. The Ontong Java Plateau today covers an area of 1,860,000 km2. In the Indian Ocean another LIP began to form at c. 120 Ma, the Kerguelen P ...

Late Jurassic
The Late Jurassic is the third epoch of the Jurassic Period, and it spans the geologic time from 163.5 ± 1.0 to 145.0 ± 0.8 million years ago (Ma), which is preserved in Upper Jurassic strata.Owen 1987. In European lithostratigraphy, the name "Malm" indicates rocks of Late Jurassic age. In the past, ''Malm'' was also used to indicate the unit of geological time, but this usage is now discouraged to make a clear distinction between lithostratigraphic and geochronologic/chronostratigraphic units. Subdivisions The Late Jurassic is divided into three ages, which correspond with the three (faunal) stages of Upper Jurassic rock: Paleogeography During the Late Jurassic Epoch, Pangaea broke up into two supercontinents, Laurasia to the north, and Gondwana to the south. The result of this break-up was the spawning of the Atlantic Ocean. However, at this time, the Atlantic Ocean was relatively narrow.

Geophysics
Geophysics () is a subject of natural science concerned with the physical processes and physical properties of the Earth and its surrounding space environment, and the use of quantitative methods for their analysis. The term ''geophysics'' sometimes refers only to solid earth applications: Earth's shape; its gravitational and magnetic fields; its internal structure and composition; its dynamics and their surface expression in plate tectonics, the generation of magmas, volcanism and rock formation. However, modern geophysics organizations and pure scientists use a broader definition that includes the water cycle including snow and ice; fluid dynamics of the oceans and the atmosphere; electricity and magnetism in the ionosphere and magnetosphere and solar-terrestrial physics; and analogous problems associated with the Moon and other planets.

Basalt
Basalt (; ) is an aphanite, aphanitic (fine-grained) extrusive igneous rock formed from the rapid cooling of low-viscosity lava rich in magnesium and iron (mafic lava) exposed at or very near the planetary surface, surface of a terrestrial planet, rocky planet or natural satellite, moon. More than 90% of all volcanic rock on Earth is basalt. Rapid-cooling, fine-grained basalt is chemically equivalent to slow-cooling, coarse-grained gabbro. The eruption of basalt lava is observed by geologists at about 20 volcanoes per year. Basalt is also an important rock type on other planetary bodies in the Solar System. For example, the bulk of the plains of volcanism on Venus, Venus, which cover ~80% of the surface, are basaltic; the lunar mare, lunar maria are plains of flood-basaltic lava flows; and basalt is a common rock on the surface of Mars. Molten basalt lava has a low viscosity due to its relatively low silica content (between 45% and 52%), resulting in rapidly moving lava flo ...

Gondwana
Gondwana () was a large landmass, often referred to as a supercontinent, that formed during the late Neoproterozoic (about 550 million years ago) and began to break up during the Jurassic period (about 180 million years ago). The final stages of break-up, involving the separation of Antarctica from South America (forming the Drake Passage) and Australia, occurred during the Paleogene. Gondwana was not considered a supercontinent by the earliest definition, since the landmasses of Baltica, Laurentia, and Siberia were separated from it. To differentiate it from the Indian region of the same name (see ), it is also commonly called Gondwanaland. Gondwana was formed by the accretion of several cratons. Eventually, Gondwana became the largest piece of continental crust of the Palaeozoic Era, covering an area of about , about one-fifth of the Earth's surface. During the Carboniferous Period, it merged with Laurasia to form a larger supercontinent called Pangaea. Gondwana (and Pan ...

Deccan Plateau
The large Deccan Plateau in southern India is located between the Western Ghats and the Eastern Ghats, and is loosely defined as the peninsular region between these ranges that is south of the Narmada river. To the north, it is bounded by the Satpura and Vindhya Ranges. A rocky terrain marked by boulders, its elevation ranges between , with an average of about .Editors of Encyclopedia Britannica (2014), ''Deccan plateau India''Encyclopaedia Britannica/ref> It is sloping generally eastward. Thus, its principal rivers—the Godavari, Krishna, and Kaveri (Cauvery)—flow eastward from the Western Ghats to the Bay of Bengal. The plateau is drier than the coastal region of southern India and is arid in places. It produced some of the major dynasties in Indian history, including the Pallavas, Satavahana, Vakataka, Chalukya, and Rashtrakuta dynasties, also the Western Chalukya Empire, the Kadambas, the Yadava dynasty, the Kakatiya Empire, the Musunuri Nayakas regime, the Vijayana ...
