How To Pronounce Tamu Massif: Tamu Massif pronunciation
Tamu Massif made news in 2013, thought to be the world’s largest volcano. New research offers a better look at the volcano’s formation and throws doubt on that claim.A New Understanding of Tamu Massif‘Certainly One of the Largest’The discovery of Tamu Massif, a gigantic volcano located about 1,000 miles east of Japan, made big news in 2013 when researchers reported it was the largest single volcano documented on earth, roughly the size of New Mexico.New findings, reported this week in Nature Geoscience, conclude that it is a different breed of volcanic mountain than earlier thought, throwing into doubt the prior claim that it is the world’s largest single volcano.The study analyzed magnetic field data over Tamu Massif, finding that magnetic anomalies — perturbations to the field caused by magnetic rocks in the Earth’s crust — resemble those formed at mid-ocean ridge plate boundaries.William Sager, a geophysicist at the University of Houston and senior author for the paper, said the discovery led researchers to conclude that Tamu Massif formed by mid-ocean ridge “spreading,” the geologists’ term for creation of ocean crust at mid-ocean ridge plate boundaries, rather than as a shield volcano, as previously thought. Shield volcanos are formed primarily as stacks of fluid lava flows and are one of the most common types of volcano.An international group of researchers — from Texas, China and Japan — sought to understand how the massive Tamu Massif volcano formed near the nexus of three spreading ridges. The key, they report, is magnetic anomalies.Mid-ocean Ridges — plate boundaries where oceanic plates move apart — are themselves large volcanoes. These ridges record distinctive linear magnetic anomalies, parallel to the ridge, as they form new crust. This is a result of lava flows and magma being concentrated near the ridge axis where the magnetic minerals in the new crust record reversals of the magnetic field polarity.A New Understanding of Tamu MassifLinear magnetic anomalies formed by the three ridges had previously been found around Tamu Massif, but it was unclear where they stopped within the volcano. A paper published in 2013 by Sager and colleagues concluded that Tamu Massif is an enormous shield volcano, formed by far-reaching lava flows emanating from its summit.The latest study compiled a magnetic anomaly map over Tamu Massif, using 4.6 million magnetic field readings collected over 54 years along 72,000 kilometers of ship tracks. The data set was anchored by a new grid of magnetic profiles, positioned with modern GPS navigation, collected by the study authors using the Schmidt Ocean Institute ship Falkor. The resulting map shows that linear magnetic anomalies around Tamu Massif blend into linear anomalies over the mountain itself — implying that the underwater volcano formed by extraordinary mid-ocean ridge crustal formation.Sager said the finding is important because it demonstrates that Tamu Massif and other oceanic plateaus are formed by a different process than previously thought. A widely-accepted model suggests a large blob of magma, known as a “mantle plume,” rises through the mantle and creates a massive volcanoTamu Massif - cdn.exploreplanet3.com
When it arrives at the surface. This eruption is thought to be analogous to massive eruptions on land, called “continental flood basalts” and it creates a vertical succession of lava flows.The ocean-ridge-spreading hypothesis suggests the age progression is instead lateral. New material is always added at the center of the ridge as older material drifts laterally away. An implication is that the gradual slopes of Tamu Massif are not caused by lava flow shape but instead by a gradual inflation and then deflation of ridge volcanism as the crust became thicker and then grew thinner.The new finding also weakens the accepted analogy between eruptions of continental flood basalts and oceanic plateaus because the formation mechanisms are shown to be different, Sager said.‘Certainly One of the Largest’With the discovery, Sager said Tamu Massif can no longer be considered the world’s largest shield volcano. That title reverts to Mauna Loa, on the island of Hawaii.“The largest volcano in the world is really the mid-ocean ridge system, which stretches about 65,000 kilometers around the world, like stitches on a baseball,” Sager said. “This is really a large volcanic system, not a single volcano.”Researchers now think Tamu Massif formed as part of that mid-ocean ridge system, he said. “Tamu Massif is certainly one of the largest volcanic mountains in the world.”The 2013 paper was based on what researchers knew at the time, Sager said. “Science is a process and is always changing.

A After 36 days of battling sharks that kept biting their equipment, scientists have returned from the remote Pacific Ocean with a new way of looking at the world’s largest – and possibly most mysterious – volcano, Tamu Massif.B The team has begun making 3-D maps that offer the clearest look yet at the underwater mountain, which covers an area the size of New Mexico. In the coming months, the maps will be refined and the data analyzed, with the ultimate goal of figuring out how the mountain was formed.C It’s possible that the western edge of Tamu Massif is actually a separate mountain that formed at a different time, says William Sager, a geologist at the University of Houston who led the expedition. That would explain some differences between the western part of the mountain and the main body.D The team also found that the massif (as such a massive mountain is known) is highly pockmarked with craters and cliffs. Magnetic analysis provides some insight into the mountain’s genesis, suggesting that part of it formed through steady releases of lava along the intersection of three mid-ocean ridges, while part of it is harder to explain. A working theory is that a large plume of hot mantle rock may have contributed additional heat and material, a fairly novel idea.E Tamu Massif lies about 1,000 miles (1,600 kilometers) east of Japan. It is a rounded dome, or shield volcano, measuring 280 by 400 miles (450 by 650 kilometers). Its top lies A new cruise and went back to collect the new magnetic data set that led to this new result.“In science, we always have to question what we think we know and to check and double check our assumptions. In the end, it is about getting as close to the truth as possible — no matter where that leads.”In addition to Sager, corresponding author and professor of geophysics in the UH College of Natural Sciences and Mathematics, other authors on the paper include: co-corresponding author Yanming Huang, Yangtze University; Masako Tominaga and John A.

Mauna Loa is one of the biggest volcanoes in the world. Keep reading to discover more Mauna Loa facts with this handy Homework Help Geography guide. Mauna Loa is the largest active volcano in the world. Keep reading to learn more amazing facts about Mauna Loa and how it was formed.Where is Mauna Loa?Mauna Loa is one of five volcanoes that forms Hawaii. Hawaii is an island state which is part of the United States. These five volcanoes are called Kilauea, Mauna Loa, Mauna Kea, Hualalai, and Kohala. The oldest volcano is Kohala at over 1 million years old and the youngest is Kilauea at 210,000 to 280,000 years old. What type of volcano is Mauna Loa?Mauna Loa is a shield volcano. This type of volcano has gently sloping sides and a broad dome. Lava from a shield volcano eruption travels further in thinner flows than lava from a stratovolcano. Mauna Loa has three craters at its summit which overlap. These three craters make up the summit caldera called Moku‘āweoweo. A caldera is a cauldron-like crater at the top of a volcano that is left after an eruption.How tall is Mauna Loa?The summit of Mauna Loa is 4170 metres above sea level. However, the sides of Mauna Loa continue another 5000 metres below sea level. If all of Mauna Loa was above sea level it would be taller than Mount Everest (8849 metres). How old is Mauna Loa?Mauna Loa is the second youngest of the five volcanoes of Hawaii. It’s thought that it’s at least 700,000 years old. It first emerged from the sea around 400,000 years ago.How was Mauna Loa formed?Mauna Loa was created by tectonic plate activity. The Pacific plate moved over the Hawaii hotspot. The Hawaiian hotspot is where the Pacific plate created the 6 islands of Hawaii one after the other. The Pacific plate slid over a plume of magma (molten rock). This is the hotspot. Volcanoes, like Mauna Loa, are created when lava erupts from the Earth’s crust. As the lava cools, it hardens to form new land. This process took a long time and began around 70 million years ago.Hawaii still has a lot of volcanic activity. Mauna Loa and Hualalai are the only volcanoes that are currently active on the Big Island of Hawaii. Mauna Loa would have begun as an underwater volcano before being gradually built up to rise above sea level. When did Mauna Loa last erupt?Mauna Loa last erupted on 27th November 2022. This eruption lasted until 13th December 2022. It was the volcano’s first eruption since 1984. As of 2024, no recent eruptions of Mauna Loa have caused any deaths but eruptions in 1926 and 1950 destroyed houses.10 Fun Facts about Mauna Loa?Here are some more fun facts about Mauna Loa:1. Mauna Loa is the world’s third-largest volcano after Pūhāhonu and the Tamu Massif. Pūhāhonu is the remnants of an ancient volcano and the Tamu Massif is an extinct underwater volcano.2. Mauna Loa’s name means “long mountain” in Hawaiian.Tamu Massif – Animals Lyrics - Genius

More than a mile (about 2,000 meters) below the ocean surface and is 50 times larger than the biggest active volcano on Earth, Hawaii’s Mauna Loa. Sager published a paper in 2013 that said the main rise of Tamu Massif is most likely a single volcano, instead of a complex of multiple volcanoes that smashed together. But he couldn’t explain how something so big formed.F The team used sonar and magnetometers (which measure magnetic fields) to map more than a million square kilometers of the ocean floor in great detail. Sager and students teamed up with Masao Nakanishi of Japan’s Chiba University, with Sager receiving funding support from the National Geographic Society and the Schmidt Ocean Institute.G Since sharks are attracted to magnetic fields, the toothy fish “were all over our magnetometer, and it got pretty chomped up,” says Sager. When the team replaced the device with a spare, that unit was nearly ripped off by more sharks. The magnetic field research suggests the mountain formed relatively quickly, sometime around 145 million years ago. Part of the volcano sports magnetic “stripes,” or bands with different magnetic properties, suggesting that lava flowed out evenly from the mid-ocean ridges over time and changed in polarity each time Earth’s magnetic field reversed direction. The central part of the peak is more jumbled, so it may have formed more quickly or through a different process.H Sager isn’t sure what caused the magnetic anomalies yet, but suspects more complex forces were at work than simplyComments
