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.
