Earthquake

Earthquake Recently, when an earthquake with a magnitude of 6.6 rocked Nepal, killing a few people and destroying many homes, India experienced strong vibrations. Why did these tremors occur? The India and Eurasia Plate collisions, the primary cause of seismicity in the Himalayas, are cited by the United States Geological Survey (USGS) as the cause of the earthquakes. At a relative pace of 40–50 millimetres each year, these plates are convergent. This region is one of t

Mauna Loa Volcano

Mauna Loa Volcano The world's biggest active volcano, Mauna Loa, might explode at any moment. Where is Mauna Loa? Mauna Loa is one of five volcanoes that make up Hawaii's Big Island. It is the most southern of the Hawaiian islands. It is not the tallest (that honor belongs to Mauna Kea), but it is the largest and accounts for roughly half of the island's land mass. It is located directly north of the Kilauea volcano, which is currently erupting from its sum

Climate Change and the Rainbow

Climate Change and the Rainbow According to a recent study, the changes in cloud cover and liquid precipitation brought on by higher greenhouse gas emissions are expected to result in a net increase in the mean number of rainbow days worldwide each year. By 2100, the average number of rainbow days is anticipated to increase globally by 4.0–4.9% per year. What about Rainbows has the study revealed? Locations with Fewer Rainbows Rainbow days will disappear from abou

Cyclone Sitrang

Cyclone Sitrang Cyclone Sitrang impacted Bangladesh by slamming into low-lying, highly inhabited areas. The first tropical cyclone of the 2022 post-monsoon season, Sitrang, was given its name by Thailand. The last storm to hit the Bay of Bengal in October in 2018 was Titli. What are the Tropical Cyclones? A tropical cyclone is a powerful circular storm with low air pressure, strong winds, and heavy rain that develops over warm tropical waters. The eye, a center region with

Storm Sitrang in the Bay of Bengal

Storm Sitrang in the Bay of Bengal The first Tropical Cyclone of the 2022 post-monsoon season, Sitrang, is expected to form in the Bay of Bengal on October 24. Titli was the last October cyclone in the Bay of Bengal in 2018. About Storms of severe severity emerge in the North Indian Ocean — comprised of the Bay of Bengal and the Arabian Sea — in the months of October-November and May-June, with an average of five developing per calendar year. October has

Ocean Currents and Global Warming

Ocean Currents and Global Warming A recent study claims that the Galápagos Islands have been protected from global warming by cold ocean currents. Key Study Findings Combating Global Warming: The islands are shielded from the warming Pacific Ocean by a chilly, eastward equatorial ocean current, which has been strengthening for decades. Since the early 1990s, the temperature of the water off the west coast of the Galápagos Islands has decreased by 0.5

Desertification and Land Degradation

Desertification and Land Degradation To rehabilitate degraded land and stop the spread of desert in India, the government intends to combine the Pradhan Mantri Krishi Sinchayee Yojana (PMKSY) and the Mahatma Gandhi National Rural Employment Guarantee Scheme (MGNREGS). Major Points: Rising Degraded Land: At least 30% of India's total geographic area falls under the category of "degraded land," according to the Desertification and Land Degradation Atlas 2021.

Melting of Arctic Ice & Ocean acidification

Melting of Arctic Ice & Ocean acidification The western Arctic Ocean's altering chemistry has just been brought to light by a research team. Information about the study Research findings: Three to four times quicker than other ocean waters, the acidity levels in Arctic seas are rising, according to the study. Seawater typically has a pH of 8.1, making it alkaline. The team also discovered a significant link between the rate of ocean acidification and the accelerated r

World’s largest iceberg breaks off from Antarctica

World’s largest iceberg breaks off from Antarctica A huge ice block has broken off from western Antarctica into the Weddell Sea, becoming the largest iceberg in the world and earning the name A-76. It is the latest in a series of large ice blocks to dislodge in a region acutely vulnerable to climate change, although scientists said in this case it appeared to be part of a natural polar cycle. Slightly larger than the Spanish island of Majorca, A-76 had been monitored by scientist

STEVE Phenomenon

STEVE Phenomenon After a severe solar storm struck Earth, the astronomical phenomena known as "Strong Thermal Emission Velocity Enhancement (STEVE)" made an unexpected appearance About STEVE phenomenon STEVE first emerged in the skies in 2017, and since then, he has returned frequently. The assertion that the phenomena have been visible in the sky since 1705 is supported by evidence. It is an extremely uncommon, enigmatic, luminous purple arc that appears nearer to
