Research mission discovers five new hydrothermal vents in highly volcanic region of eastern Pacific Ocean
Researchers have learned that the site responsible for more than 75 percent of the world’s volcanic activity is more active than previously thought as they recently discovered five new hydrothermal vents, each spewing fluids hotter than 570°F.
Oceanographers have explored the area around the Nazca Ridge in the Pacific Ocean and discovered a huge underwater mountain
Oceanographers led by the Schmidt Ocean Institute exploring the depths of the Pacific Ocean discovered a huge seamount in September 2024. The 3,109-meter-high seamount is a major find. It is one of many discoveries made during a 28-day survey in late summer by oceanographers on the research vessel Falkor. But satellites are no less important in exploring the ocean depths — satellites are mapping the Earth’s ocean floor in unprecedented detail.
Indonesian volcano eruption leaves people dead and forces large-scale evacuations
The eruption of Indonesia’s Lewotobi Laki Laki stratovolcano has killed at least 10 people on the island of Flores after volcanic debris and hot ash fell and burned homes. In eastern Indonesia, the Lewotobi Laki Laki volcano erupted again on Saturday, sending a giant plume of ash reaching nine kilometres into the sky. The eruption was the latest in a series of events that began days ago, killing nine people and forcing thousands of residents to evacuate.
The eruption of one small volcano can affect the climate of the Earth’s hemisphere for a couple of years
Antarctica is dotted with volcanoes, waiting to erupt. And a volcano in Tanzania and volcanoes in Iceland are close to erupting. The Tonga eruption, which released 150 megatons of water vapor into the stratosphere, affected the atmosphere for years. Satellite data suggests that a volcano in Tanzania, which spews extremely fluid lava, may be close to erupting. Iceland is threatened by uncontrolled volcanic eruptions due to climate change.
Kamchatka’s Shiveluch Volcano Is Active Again
To date, the Shiveluch volcano is known to have erupted in 1790, 1854, 1879-1883, 1896-1898, 1905, 1927-1929, 1944-1950, 1964, 1980-1981, 1993-1995, 2001-2003, 2008-2016. As a result of the 2004-2005 eruption, the height of the volcano decreased by 115 meters. Scientists called the eruption of the Shiveluch volcano in Kamchatka, which began on November 7, “uncharacteristic” and warned that the giant has become even more dangerous. Since the beginning of 2024, seismic and volcanic activity has been growing in Kamchatka.
Features of the landscape on Mars – new discoveries
Olympus Mons is one of a dozen large volcanoes, many of which are ten to a hundred times taller than their Earthly counterparts. If Martian space tourism takes off in the coming decades, Olympus Mons could become a prime destination for adventure enthusiasts. Olympus may once have been a volcanic island surrounded by an ocean nearly 4 miles (6 km) deep, according to geological evidence found in the high cliffs. Another new study found that the rover discovered polygonal wedges 35 kilometers underground – the first time they have been discovered beneath the planet’s surface. Evidence suggests that the wedges formed between 3.7 and 2.9 billion years ago due to major climate changes in Mars’ past. The Mars Express orbiter has discovered enough water ice buried beneath the Red Planet’s equator to cover the entire planet in a shallow ocean if it melted.
Climate control technologies and critical points of no return are on the agenda
Experts examined the problem of so-called critical points, in which the behavior of natural systems changes in an unpredictable way. According to one hypothesis, if the atmosphere overheats, the collapse of the Gulf Stream and the death of the Amazon forests, an important carbon dioxide sink, are possible. The threshold is unknown, but as noted in the report, the likelihood of crossing it increases.
Increased volcanic activity has been recorded in Japan and Iceland
Volcanoes in seismically troubled island states have shown increased activity. A state of emergency has been declared in the south of Iceland due to the eruption of the Fagradalsfjall volcano. Before the awakening of the giant, an earthquake occurred in the country. A volcano erupted on Suwanose Island in Japan’s southwestern Kagoshima Prefecture.
One of the most active volcanoes in the world in Kamchatka threw out two columns of ash to a height of up to 10 thousand meters
According to seismic data, on April 20, ash emissions occurred at the Karymsky volcano to a height of 6 thousand meters. and about 10 thousand m. above sea level, respectively. As noted by the Kamchatka Volcanic Eruption Response Team, the ash plume spread to the southwest of the volcano.
Bezymyanny volcano in Kamchatka continues active volcanic activity
On March 16, a powerful eruption occurred with the release of lava and ash from the Bezymianny volcano. The resulting huge cloud of ash flies to Chukotka, reports the Kam 24 news agency. Bezymyanny’s aviation hazard code is orange. This means that ash emissions from the volcano’s crater could pose a threat to local airlines.
South Pole Ice Sheet Contains Major Volcanic Activity
The scan showed that in Antarctica, 138 volcanoes rest under 3-4 km of ice, 91 of which are geologically hazardous objects.
The modern landscape on Mars was formed by major floods, and there is still oxygen in the atmosphere
The composition of the rock on Mars indicates volcanic activity, the presence of bodies of water, primitive organisms and a stable environment for the origin of life in the past.
The Cumbre Vieja volcano on the Spanish island of La Palma has covered the surrounding residential area with a thick layer of lava and ash for the second month
Experts from the National Geographic Institute of Spain cannot yet predict when the volcanic eruption on the island of Palma will stop. Cumbre-Vieja woke up on September 19 and remains highly active.
Volcanic activity on Mars prevents water from completely evaporating
Seismic activity on Mars indicates tectonic activity that is similar to that on Earth. The NASA InSight probe detected earthquakes on Mars with an amplitude of up to 4 points.
