The massive extinct volcano that is home to the cloud is Arsia Mons, a 20 km high (12.4 miles) landmark on Mars’ surface. Today’s VIS image is located on the lower flank of Arsia Mons. The volcano is 435 kilometres (270 mi) in diameter, and almost 20 kilometres (12 mi) high. As I said in my last post in February showing recent pit discoveries on Mars, I could almost make this a monthly series.In the March image download from the high resolution camera of Mars Reconnaissance Orbiter (MRO) were three (maybe four) more pits, all likely skylights above lava tubes and all located near the giant volcano Arsia Mons in the region dubbed the Tharsis Bulge. It’s made up of water ice, and while it may look like a smoke plume linked to volcanic activity, its airflow is directly influenced by the volcano’s ‘leeward’ slope, or the non wind-facing side. Mons, Pavonis Mons and Arsia Mons. A strange, long, thin cloud cloud has again appeared over the 20-km high Arsia Mons volcano on Mars. As a result of this rather strange encounter it became known as the Arsia Mons Elongated Cloud and it was listed off as unexplained and unknown by the team of … Hecates Tholus is 180 km across and 4.8 km high. It was found that the latest flow dated almost 50 million years back. A curious elongated cloud, extending west of the Arsia Mons volcano on Mars, seen in a Mars Express image taken October 10, 2018.

When the Martian volcano Arsia Mons exploded long ago, it sent lava spewing out everywhere. Coincidentally Olympus Mons is relatively close to the Tharsis Trio (right). This VIS image is located on the SE flank of Arsia Mons volcano where it meets the plains. Arsia Mons is the southernmost of the Tharsis volcanoes. Arsia Mons is one of the youngest volcanoes on Mars. Since it is also made up of water ice, this completely checks out the volcano as the possible culprit behind this cloud. Arsia Mons is located just south of the planet Mars’ equator and is part of the Tharsis Montes group together with Pavonis Mons and Ascraeus Mons. The lava flows originating from Arsia Mons are among the youngest on the surface … Continue reading → Olympus Mons, the largest volcano in the Solar System is located on Mars. The volcano was mainly active over a period ranging from 2.5 to 0.5 Gyr It is 270 miles (450 km) in diameter, almost 12 miles (20 km) high, and the summit caldera is 72 miles (120 km) wide. These collapse features likely occur over lava tubes that served as conduits for flows from within the volcano. Its name formally became Pavonis Mons in 1973. The cloud is a recurrent feature on Mars, appearing annually above Arsia Mons, a 12.4-mile-high (20-kilometer) volcano located near the Martian equator. For comparison, the largest volcano on Earth is Mauna Loa. Photo credit: ESA/GCP/UPV/EHU Bilbao A bizarre thin elongated cloud has recently appeared over the 12.4-mile high Arsia Mons volcano on Mars. Collapse features are present at the margin of the volcano. The linear features are tectonic faults. While Arsia Mons may be larger than any volcano on Earth, it pales in comparison to the largest volcano yet discovered in the solar system, Olympus Mons, which measures 22km (16mi) high. Dykes arrange in typical patterns within a given stress-field as e.g. It is 270 miles (450km) in diameter, almost 12 miles (20km) high, and the summit caldera is 72 miles (120km) wide. Pavonis Mons is a large shield volcano located in the Tharsis region of the planet Mars. The Visual Monitoring Camera (VMC) attached to Mars Express captured a mysteriously long, thin cloud over the 20 km (12 miles) high Arsia Mons volcano on July 17 and 19, 2020. With the removal of this molten material, the volcano then collapsed at its opening (the top of its cone) to form a sunken volcanic crater known as a caldera. In the search for lost water on this planet the areas of most recent volcanic activity are probably most likely to reveal the still existing sources of water ice. The slopes of the volcano are heavily dissected with channels, suggesting that the volcano is composed of easily erodible material such as volcanic ash. Mars is too cold for liquid water, so the cloud is made of water ice. Click here for an annotated version of this image, which is via ESA. Scientists say the curious plume is not linked to volcanic activity, but forms as airflow is influenced by the side of the volcano that does not face the wind. Arsia Mons, Pavonis Mons and Ascraeus Mons, are gigantic volcano triplets of a youthful age with evidence of recent volcanism (Hartmann et al., 1999). Arsia Mons is 12 miles high and 270 miles wide, dwarfing Mauna Loa, Earth’s largest volcano, which is only 6.3 miles high and 75 miles wide, and mostly underwater. From its base on the sea floor, Mauna Loa measures only 6.3 miles high and 75 miles in diameter. Two distinct levels (‘‘a’’ and ‘‘b’’) can be seen within this 1.0 km-high cliff section (top of cliff is towards It’s a shield volcano, so named for its shape due to a very fluid lava that gets deposited farther than in other types of volcanoes that have a much denser lava. The last volcanic activity there ceased about 50 million years ago -- around the time of Earth's Cretaceous-Paleogene extinction, when large numbers of our planet's plant and animal species (including dinosaurs) went extinct. The cloud made an appearance over the volcano before, in 2018. THEMIS Image of the Day, July 1, 2019. This image of the Arsia Mons shield volcano was taken by the High Resolution Stereo Camera (HRSC) on board ESA's Mars Express. Thursday 30 July 2020 13:19. The volcano Arsia Mons, located in the Tharsis region of Mars, was chosen as study region (Figure 1). Arsia Mons is 12 miles high and 270 miles wide, dwarfing Mauna Loa, Earth’s largest volcano, which is only 6.3 miles high and 75 miles wide, and mostly underwater. Arsia Mons (ar -see-ă) A 14-km-high 400-km-wide volcano at the southern edge of the Tharsis Ridge of Mars.It is located just south of the Martian equator at the aerographic coordinates 8.4° S latitude, 121.1° longitude (see areography).It appears to be older than the other Tharsis volcanoes and has the largest summit caldera, 140 km across. Adam Smith @adamndsmith. The volcano was discovered by the Mariner 9 spacecraft in 1971, and was originally called Middle Spot. Arsia Mons is the southernmost of the Tharsis volcanoes. 0 comments. Reykjavik - June 5, 2001 - The Tharsis Montes on Mars (Figure 1), i.e. regional dykes, It culminates at 17.7 km for a diameter of 400 km and flank slopes are 5 . Mysterious Martian cloud reappears above Arsia Mons volcano. The hypothesis is that pit crater chains are related to magmatic sheet intrusions (dykes). You can see it more fully in the context image to the right. Arsia Mons volcano in black and white The total height difference in the land surfaces in these scenes is about 7 kilometres, and some individual collapse pits have a depth of 2 kilometres. This image taken by the High Resolution Stereo Camera (HRSC), shows a zone of collapse features on the southern flank of the giant shield volcano Arsia Mons located at 239° E longitude and 10° S latitude. The many pits of Arsia Mons May 7, 2019 1:57 pm Robert Zimmerman When it comes to Mars, it appears that if you want to find a pit that might be the entrance to an underground system, the place to look is on the slopes of Arsia Mons, the southernmost volcano in the chain of three giant volcanoes between Olympus Mons to the west and the vast canyon Marineris Valles to the east. Please see the THEMIS Data Citation Note for details on crediting THEMIS images. The modeling also revealed the fact that the Arsia Mons volcano produced around 1 … Prodigious ash deposits near the summit of Arsia Mons volcano, Mars Peter J. Mouginis-Mark ... Mons, where a 12 km-wide graben is located at an elevation of 6.2 km. The item Geologic map of Arsia Mons Volcano, Mars, U.S. Department of the Interior, U.S. Geological Survey ; by David H. Scott and James R. Zimbelman ; prepared for the National Aeronautics and Space Administration represents a specific, individual, material embodiment of a distinct intellectual or artistic creation found in Indiana State Library. This image from NASA's 2001 Mars Odyssey spacecraft shows part of the southeastern flank of Arsia Mons, including the flat lying flows around the base of the volcano. Image Credit: ESA/DLR/FU Berlin, CC BY-SA 3.0 IGO In 2018, when the news of the “oddly-shaped cloud” went viral, Dr. Tanya Harrison from NASA explained that the odd feature was not a plume of smoke, but rather water ice clouds condensing out over the summit of the Arsia Mons volcano. For comparison, the largest volcano on Earth is Mauna Loa. It is the middle member of a chain of three volcanic mountains that straddle the Martian equator between longitudes 235°E and 259°E. Arsia Mons volcano in 3D This image of the Arsia Mons shield volcano was taken by the High Resolution Stereo Camera (HRSC) on board ESA’s Mars Express. These flows are located at … New NASA research reveals that the giant Martian volcano Arsia Mons produced one new lava flow at its summit every 1 to 3 million years during the final peak of activity. The plume above the Arsia Mons volcano on Mars. Elysium Mons is only about one-fifth the volume of Arsia Mons. They form a chain trending from northeast to southwest where Ascraeus Mons is northernmost and Arsia Mons is located at the south end of this chain (5 S–230 E).
