Mount St. Helens
A mountain in the Cascade Range in Washington state, Mount St. Helens, erupted on May 18, 1980, causing an enormous volcanic eruption and devastating the nearby area. Approximately 57 people died, and 210 square miles of forest and wilderness were destroyed. The massive eruption caused a half-mile-wide crater, one to two miles wide and up to 0.5 miles deep.
In the aftermath of the eruption, small explosions continued to occur daily, but people familiar with the mountain noticed changes in the north face. It was later revealed that a bulge one-half mile wide was moving upwards at six feet per day, which had been caused by the intrusion of magma from beneath. Authorities began evacuating all the locals, which amounted to hundreds of people from the area, though some were stubborn and refused to leave their homes.
Before the 1980 eruption, Mount St. Helens was Washington's fifth-highest peak. It was also nicknamed the Fuji-san of America and the "Baron St. Helens." The name was given to the mountain in honor of Alleyne Fitzherbert, an 18th-century British diplomat. The Mount St. Helens National Volcanic Monument was officially established by President Ronald Reagan in 1982 and is a popular hiking destination today.
The first eruption is measured scientifically to have started around 37,600 years ago. Smaller-volume eruptions characterized this stage with dense pyroclastic flows. The eruptive activity was over, and it took another 17,000 years to return to normal. The lava from this eruption filled the Lewis River valley.
Mount Etna may be the most beautiful one of the most potent volcanoes on Earth. Its eruptions follow a pattern that varies from smaller craters to large craters. However, its recent activity was relatively mild compared to its past. The volcanic activity at Etna began around 1500 BCE, and the most recent eruption resulted in over 15,000 deaths.
The eruption of Etna caused considerable damage to the surrounding area, but it was relatively insignificant and did not threaten any buildings or infrastructure. The eruption did, however, severely damage the cable car station and Etna Sud, which are popular tourist destinations.
A volcano's activity is an integral part of the geological process, and Mount Etna is one of the five most active volcanoes in Europe. Extensive lava flows accompany its eruptions, but they rarely threaten inhabited areas. The historical records of eruptions on Etna are the most comprehensive range of any volcano in the world. Its eruptions have a variety of forms, including effusive lava flows, summit eruptions, and flank eruptions.
Mount Etna is a fascinating volcano to visit. It has erupted for thousands of years, but the most recent collapse occurred in February 2021. In 396 BCE, Etna erupted and halted the Carthaginian attack on Syracuse. In the twentieth century, several notable eruptions have occurred on Etna. Its located in Sicily, an Italian island in the Mediterranean Sea. It is the tallest active volcano in Europe, rising over 3,300 meters and covering an area of more than 100 square miles. Visitors flock to Etna's caldera to see its volcanic soil, which is beneficial for farming.
Japan is home to Mount Fuji, one of the world's most famous volcanoes. Located about 150 km from the capital of Tokyo, Fuji is often visited by tourists and locals alike. Despite its remote location, Fuji is prone to seismic activity. Scientists have been monitoring the volcano for years, but it wasn't until recent years that they discovered an increase in the number of earthquakes below the summit.
The name of Mount Fuji is a blend of Chinese and Japanese words. The former means "mountain of fire," and the latter is derived from a Japanese word for "mountain." However, both names are still widely used, with foreign visitors referring to the mountain as Mount Fujiyama, which translates to "Mount Fuji mountain." This tells you that they are exactly just tourists.
While the first eruption of Mount Fuji was around 700,000 years ago, its activity was relatively low until about seven thousand years ago. Following the Great Sendai Earthquake in 2011, a magnitude-6.4 aftershock struck Mount Fuji's southern flank.
Visiting Mount Fuji is a spectacular experience, but stay alert! The Japan Meteorological Agency constantly monitors volcanic activity. There are five levels of warning, ranging from level one, meaning it's in a "normal" state. At level two, a no-entry zone is in place around the crater. Level three prohibits hiking up the mountain. At level four, visitors are warned to avoid the mountain, while level five alerts residents to evacuate immediately.
According to Japanese tradition, climbing Mount Fuji is considered a religious activity. A shrine in the crater area is dedicated to the Buddhist god Konohana Sakuya Hime. Buddhists believe Fuji to be the abode of the Buddha of All-Illuminating Wisdom. And as a result, Mount Fuji is a famous symbol of Japan. The World Heritage List added the volcano to its Cultural Site in June 2013.
The Mount Misti volcano is located in Arequipa, Peru, and is considered a city symbol. Its ash-mantled terminations are typical of young lava flows. In addition, the upper flanks are covered in dark deposits that may have accompanied the formation of the inner crater scoria rim. Its tephra is also covered on much of the flat northeastern plain, and prevailing south-westerly winds probably transported it. This has resulted in an impressive parabolic dune field of volcanic ash that stretches for a reasonable distance.
The Misti volcano was last active in the 15th century and is inactive today. However, it was an essential part of the Inca people's activities. Near the crater are traces of Inca ritual sacrifices. It is now one of the most popular tourist destinations in Arequipa, Peru. Different agencies arrange tours of Mount Misti volcano. While the trek is strenuous, it gives visitors an unparalleled view of the city.
The Rio Chili canyon is a vital artery incising the west flank of El Misti. A series of valley-confined PC deposits form 5-8 m thick fans on the SW slopes. Several of these PC deposits are preserved in valley-confined conditions, including the Rio Chili and the San Lazaro canyons, which are 13 km away from the vent. It is also possible to spot several hydrothermal vents at Mount Misti, which are present in both craters.
Mount Misti is the most visited volcano in the country, located 16 km southwest of Arequipa. Among the five famous volcanoes in Peru, it has a tumultuous history and is considered a very active volcanic area. There are two concentric summit craters, the outer one measuring 830 m in diameter and the inner crater measuring 450 m in diameter.
Vesuvius is a volcano that erupted over 40 times in the past 2000 years, devastating the city of Pompeii and the surrounding area. It is one of the most dangerous volcanoes in the world and among the most active in Europe. This active volcano is expected to erupt again, and a future eruption could endanger up to six million people.
Vesuvius formed as a result of a collision between two tectonic plates. The African plate was pushed under the Eurasian plate, causing the upper plate to detach from the lower plate. This resulted in the melting of different rock types in the crust, which favors violent eruptions. The volcanic rock, called andesite, is made of silica, which creates a sticky magma that can cause explosive eruptions.
The Vesuvius eruption was a devastating event that occurred without warning. Massive amounts of debris were ejected into the air. Some of this debris fell near Pompeii and Herculaneum. And is one of five famous active volcanoes in the world and is the only one on mainland Europe, located on the west coast of Italy, near Naples. Mount Somma, a semicircular ridge that rises to 3,714 feet (1132 meters), sits just north and is the second highest. Valle del Gigante and Mount Vesuvius surround it.
Mount Vesuvius is one of Italy's most famous active volcanoes. It violently erupted in AD 79 and buried Pompeii, leaving behind a trail of volcanic ash and pyroclastic material. Visitors can even feel the fumes and vapors from the crater today.
