What is the larger-sized tephra?
The larger-sized tephra is known as volcanic bombs. These are ejected as incandescent lava fragments that solidify while flying through the air and can reach several meters in diameter. Volcanic bombs are usually formed during explosive eruptions at volcanoes.
The largest pyroclasts are?
The largest pyroclasts, known as volcanic bombs, can have sizes ranging from a few centimeters to several meters in diameter. These molten rock fragments are ejected during explosive volcanic eruptions and solidify before hitting the ground. Their shapes can range from rounded to elongated, depending on their flight path and cooling processes.
Can humans able to predict volcanic?
volcanoes is the natural fenomenom most difficult to predict. That duty belong to the people at the seismic intitutions and seismic observatories. They are called geologists. Volcanologists monitor information from sensors near volcanoes to provide short-term forecasts of possible eruptions or changes in the course of existing eruptions. These sensors detect physical changes such as earthquake activity, shape of the volcano, and the release of volcanic gases.
How tall is Krakatoa now?
2,667 feet or 813 meters
How did Mt Rangitoto form?
Mt Rangitoto is a volcanic island in New Zealand's Hauraki Gulf that was formed by a series of eruptions around 600 years ago. The eruptions created a cone-shaped volcanic mountain that rises to a height of 260 meters above sea level. The lava flows from these eruptions spread out to create the distinctive landscape of the island.

What are the physical features of Krakatoa?
Krakatoa, an island in Indonesia, is characterized by its rugged volcanic terrain, steep slopes, and a caldera formed by past volcanic eruptions. The island's summit reaches approximately 813 meters (2,667 feet) above sea level, featuring a prominent volcanic cone known as Anak Krakatau, which emerged after the catastrophic eruption in 1883. The surrounding landscape includes lush vegetation, steep cliffs, and remnants of previous eruptions, showcasing the dynamic geological history of the region. Additionally, the island is situated in the Sunda Strait, surrounded by the Java Sea and the Sunda Shelf.
What are four facts about Mount Vesuvius?
Mount Vesuvius's major eruptions occurred in 79 A.D., 1631, and 1944. It lies in the most densely populated volcanic region in the world, and it stands over four thousand feet tall (more than a hundred meters).
Area of the largest volcanic crater?
The largest volcanic crater is Lake Tobi. This volcanic crater lake has an area of 1,130 km². It has a depth of up to 505 meters.
What are the crater dimensions of the mount etna volcano?
Mount Etna's summit craters vary in size and are constantly changing due to volcanic activity. The main crater, known as the "Bocca Nuova," has a diameter of approximately 300 meters, while the "Northeast Crater" has a diameter of around 600 meters. The overall dimensions of the summit craters can fluctuate significantly following eruptions, as new vents and fissures may form. Additionally, the height of the craters can alter as volcanic material is deposited or eroded.
An undersea volcanic formation that does not rise 1000 meters above the surrounding sea floor is called what?
An undersea volcanic formation that doesn't rise 1000 meters above the surrounding sea floor is called a seamount.
What is the approximate size of ash cinders and bombs?
Ash consists of very fine particles less than 2 millimeters in diameter, while cinders typically range from 2 to 64 millimeters. Volcanic bombs are larger, often exceeding 64 millimeters and can even be several meters in size. These size classifications help differentiate between the various types of volcanic materials ejected during eruptions.
What is the elevation of merapi?
Mount Merapi, an active stratovolcano located in Indonesia, has an elevation of approximately 2,930 meters (9,616 feet) above sea level. It is one of the most active volcanoes in the country and is known for its frequent eruptions. The elevation can vary slightly due to volcanic activity and changes in the landscape.
