It persuaded scientists to revise their views on the dangers posed by many volcanoes hidden in the ocean. Now they are looking for the submerged mountains in these oceans to protect the land and the sea. With growing modern and sophisticated methods of detecting these things, volcanic experts hope to improve the early warning system, determine environmental impacts, reduce the risks posed by volcanic eruptions, and help restore the ecosystem. Let's know who the people are trying to find out where the next underwater volcano is hidden. And where are they looking ahead? Deep sea volcanoes are much more difficult than ground-level volcanoes. In fact, we know more about the surface of the moon than we know about the sea floor. But the outbreak of Hinga Tonga has mobilized the scientific community and the community has stressed the need for further search of the unknown circle. In April 2022, New Zealand's National Institute of Water and Atmospheric Research (NEVA) began a voyage for a dramatic bursting site in Tonga. Their ship, RV Tangarao, surveyed thousands of square kilometers of seafood and collected video images and samples, and based on them, are now being re-studied.

Mike Williams, chief scientist of the oceans in Nava, says: 'Before leaving our journey, we had only legendary information about the Tonga land.' Underwater volcanoes often fall off their own weight. When seawater is combined with magma (hot fluid emitted from the volcano), it can lead to an explosive devastation, which can result in a tsunami (and cause toxic vapors on the ground). Williams explained, "Imagine a circle cake ton that has exploded outside a ton." The researchers aboard the ship Tangarwa had a few immediate goals: mapped the location, retrieved volcanic reservoirs to help understand the chemistry of the outbreak and the geology there, and examine the impact of the Caldera on the surrounding seas. Veteran volcano and navva travel leader Kevin McKay says: 'We arrived early in the morning, and saw the sun rising between the two blurred peaks of fire torment and violence.' Once the ship reached Hunga Tonga's outer Caldera, the remote-run Deep Todd Instrument System (DTIS) traveled to the edge of the seam. From there, the unmanned boat leaned toward the sea floor like a wings torpedo, and through it the team had the opportunity to record video footage and take samples. Mackay says, 'It was a bit scary. Under our steel boat there was a risk of any kind of explosion, which meant that we could sink at any moment. ' The team's deployment of this new device facilitated them to smell the other volcanic balloons and to document the changes in the Hunga Tonga structure, and the change proved to be very dramatic. Mackay says that before the explosion, Calderra was about 120 meters (396 feet) high. Now it's a kilometer deep. In addition, we found the flow of pyroclastic (volcanic lava), which was like a tumultuous, dense, rugged river that flows along the seabed. It is spreading at least 60 km (37 miles) at all angles. ' The trip to Nava was part of the Tonga Irrigation Seed Mapping Project. The campaign was financed by a non-profit Nippon Foundation based in Japan, which has been assisting underwater research since 1962. It should be noted that the organization aims to map the world's maritime floor by 2030. Although Nava does not actively monitor the underwater volcano, the organization has an active research program ready to test the oceans, including many endangered volcanoes.

However, what scientists have observed can give us hints about future disasters. For example, in 2018, an underwater volcano erupted in France's Mayote island, causing a new hurricane, which revealed a high level of earthquake in the region. Maybe is now constantly monitored and its activity is regularly updated by a group of scientists on the Revosima. Revosema is an integrated platform that monitors the dangers of volcano such as magma flow, water temperature and acidity as well as earthquakes. Efforts such as rivosima are especially important for monitoring the ongoing volcanic activity, but they are extraordinarily expensive. The crew can spend up to 50,000 euros a day on time and operations. Protecting the cable near the volcano location (which allows local data collection) can cost millions. It takes years to raise and build funding for infrastructure. But this research is very important. Not only because we can detect the dangers posed by active volcanoes, but it is also important that we can better understand the environmental impacts of the volcano. 'The more dangerous are those that are near the sea' The way these natural phenomena occur can tell us how the ecosystem is restored, because the eruption of the volcano destroys the same kind of destruction as human mining, sea travel, fishing and other excavations. For example, underwater volcanoes can mostly be caused by seawater or the accumulation of seaweed. "People are interested in the volcano because there is a danger," says Gavier Skarten, a researcher working in the Libertovir the Geological field in Paris's Ekl Normal Superior. 'Generally, depth volcanoes are not very risky. The more dangerous are those who are near the sea level or who are raised above it. ' There are probably about 1,500 active volcanoes spread around the world (of which about 500 have exploded in recorded time), but they do not include those who are in constant strip of volcanoes on the sea floor, which are said to be numerous in hundreds. Getty Images, Photo Caption, photo caption RV Tangarova recently surveyed thousands of kilometers of sea floors near New Zealand, many of which are located in the Pacific, along the Pacific, along the Pacific. The most dangerous are the volcanic islands where humans live. Escorton says: 'Imagine the level of death and destruction at the Mediterranean or Hawaii, as well as the damage to the economy and the transportation system. But of course we can't study the volcano unless they know where they are. ' How do they find underwater volcanoes? How do volcanic knowledge experts find underwater volcanoes, especially when metric data is relatively low? One of the answers is hydroxystic surveillance. When a volcano explodes underwater, it produces sound energy: As hot as 1200-grade when it is almost frozen seawater, it becomes vapor, causing a loud explosion, faster cracks and thunderbolts into seizures. At a depth of about 1,000 meters (3,300 feet), pressure, temperature and salts combine to reduce the movement of sound in water and facilitate its delivery. This zone is known as the sound-fixing and ranging channel (whales use the same sound channel to communicate with each other underwater). Hydrophones or underwater microphones can detect sound signals from earthquake sound waves along the sofer channel. This sound indicates the flow of lava, which is a possible warning of incoming or ongoing and active explosion. Researchers consider the collapse of volcanic islands as part of their geological history, while some expect the shores to fall into the sea, resulting in land sliding, earthquakes and major tsunamis. "Although no such incident has happened in our recorded history, the consequences can be disastrous," says Scartan. Meanwhile, geologists and volcanic experts begin to work underwater spying with the available 'crime scene'. Take the Axel Sea Mount on the northwestern Pacific coast of the United States, which, according to knowledge, is the most active underwater volcano. It exploded in 1998, 2011 and 2015 and is also the world's most surveyed underwater volcano. Bottom pressure recorders show that Excel is slowly gaining ground, while remote-driven vehicles have discovered a new lava flow, which suggests that it may explode again in the near future.

Many governments have similar teams. The USG volcano who wished to detect volcanoes can get help with the volcanic films, as well as many questions in volcanic films (it has been revealed that scientists cannot walk with boiling lava in real life), but are still born in the water. Mackay says that the eruption of Hunga Tonga was different and that he confused us, the style of the volcano was not what the books tell us how he should be. There was more devastation than the super volcano in Tonga, but instead of scattering it, it remained in its place, forcing experts to re-evaluate their views on which mechanism would have caused so much destruction. There is still more ambiguity about the fact that the energy emitted from Hunga Tonga is mostly vertical rather than spread on the sea floor. Mackay says the explosion in the direction of the sky was unusual. Hunga Tonga's major blasts not only produce waves on the sea, but they also create sound waves and waves in the environment. These waves move out of their center with a certain interval. They go into the atmosphere at speeds of more than 100 km. The speed is about two times higher than the speed of a jet. Even more unusual is that the waves do not end in the traditional way, Williams says. `` Looks like they have more energy and they create a wave that was better recorded, as far as the ice shelf in Antarctica. 'Experts are still trying to collect records of such events. The Hunga Tonga blast emitted an estimated 10 million tons of TNT energy. Ashes and sea water had virtually destroyed the island. This not only caused the local infrastructure to be strained but also the water supply lines were contaminated and roads were broken. It has a worldwide impact. There are infinite number of underground brought in, any of which can come out at any time without notice. By studying Hinga Tonga, we can find out what security measures should be taken when it comes to these other underwater time bombs.
