Mauna Loa is an active shield volcano located on the island of Hawaii. Known and recognized for its incredible size and massive eruptions, Mauna Loa is one of five major volcanoes that form the island of Hawaii. Mauna Loa has been historically considered the largest volcano on Earth, and it seems that it will stay that way for a while! With a volume estimated at a whopping 75,028 kilometers, a peak of about 37 meters, and a height of 13,678 kilometers, Mauna Loa is one big bad volcano!
Mauna Loa was discovered in 1779, and with eruptions going back from 700,000-1,000,000 years ago, Mauna Loa is the 4th oldest out of the 5 subaerial volcanoes located in Hawaii. It is also the third youngest volcano in the Hawaiian-Emperor seamount chain, which

With an area of 151.26 kilometers squared, it dramatically decreased the animal and plant populations surrounding the area. One of the main causes for this dramatic decrease is vog. Vog is a smog or haze that contains volcanic dust and gasses, which can destroy vegetation and severely injure or even kill animals. Many scientists are searching and researching a way to prevent this deadly pollution from occurring, but they are having no such luck.
Mauna Loa poses many hazards to population, and so it is part of the Decades Volcanoes program. The Decades Volcanoes program encourages scientific studies of the world’s most hazardous volcanoes, and Mauna Loa is classified as one. As a result of this, Mauna Loa is being closely monitored by the Hawaiian Volcano Observatory, and has been since 1912.
The United States Geological Survey has created a hazard zone mapping of Hawaii. The mapping is on a scale of one to nine, with the most hazardous areas corresponding to the smaller numbers. Based on this classification, Mauna Loa’s continuously active summit caldera and rift zones have been given a level one designation. Much of the area surrounding the rift zones is considered a level two, and most of the remaining volcano is considered a level three. However, two sections of the volcano in the southeastern part of the volcano have been designated level

The cause of this strange interval is not yet known, and no similar pause has been discovered at any other Hawaiian volcanoes except for those currently in the post-shield stage. Between 8,000-11,000 years ago, Mauna Loa’s activity was dramatically more intense than it is today. On the other hand, Mauna Loa’s overall growth has began to slow over the last 100,000 years, and many scientists predict that Mauna Loa may be nearing the end of it’s tholeiitic basalt shield-building phase.
Overall, Mauna Loa has caused many problems economically. For instance, Mauna Loa has caused a huge loss in federal and state money. The volcano’s pyroclastic flows destroy bridges and homes, which leads to the need for major repairs. Also, the ash ruins crops and water and causes many people to become ill. This causes needs for replanting and a larger hospital staff. Finally, lava flows overrun communities which is yet again very costly.
On the other hand, Mauna Loa has caused many more tourists to visit which brings in more money. While the people are losing money due to the need to repair and clean up, in a way they are also gaining money. However, statistically they are losing more money than they are actually gaining which poses a

Crater Lake is a result of a volcanic explosion that happened about 7,000 years ago. A long time ago, the pacific oceanic plate was gradually moving under the pacific continental plate in the process of plate tectonics. The pressure shaped the land to move upward and create a line of mountains that are currently located on the Cascade Range. These lavas piled and cooled on top of each other resulting in mountains like Mazama and Hood. Mount Mazama was built by successive flows of both andesite and dacite lavas. Mount Mazama was a stratovolcano, which was about 12,000 feet high after series of ash, cinders, and pumice explosions built it upward. During it?s final eruption the magma chamber was emptying and the underlying support for the mountain was lost and the walls of the volcano began to collapse. In just a matter of days the top of the mountain was destroyed and left a caldera. A caldera is a word used by geologists to describe large basin-shaped volcanic depressions. The destruction Mount Mazama was what marked the beginning of the formation of Crater Lake. The caldera was about 3,000 feet deep and over time, snow and rai...
The Big Island is a vital part of Hawaiian history and culture. In fact, people still believe that there is a Hawaiian god that still resides there and is among the living. Supposedly, there is a volcano goddess names Pele who lives in the Kilauea Volcano. Since 1983, she has provoked eruptions at the Kilauea Volcano.
Volcanoes have always been a mysterious wonder of the world. Volcanoes have shaped the landscape and the very ground that we all live on. People have written stories of their disastrous eruptions, and painted their marvelous shapes on canvas. The essay will outline some of the more famous volcanoes and how they have impacted are history. Mount Vesuvius that destroy the great city of Pompeii, Krakatoa they spewed deadly ash on small village town, and Mount St. Helen, the only volcano in my own country to every erupt during my own time period.
Mauna Loa is Earth’s largest volcano and most massive mountain as it takes up nearly half of the flourishing landscape of the island of Hawai’i. This island is actually made up of five volcanoes, Kohala, Mauna Kea, Hualalai, Mauna Loa, and Kilauea, all in such close proximity that they fused together to form one whole island. Mauna Loa is located in the south central area of Hawai’i, in the Hawai’i Volcanoes National Park and its coordinates are 19°5' N, 155°6' W. It is 13,680 ft above sea level, but if one measures from its true base on the ocean floor, it is estimated to be 30,080 feet tall. Its name is quite fitting as it means “Tall Mountain”.
Although volcanoes are difficult to predict, geologists have made many efforts in order to caution the people of Orting and other surrounding towns of possible lahar slides. Residents have been made aware of emergency response plans and they know the proper precautions to take in the case of a volcanic activity emergency. Sirens have been put into place by the fire department and governing bodies of surrounding communities that detect volcanic activity and warn the community of ...
The eruption of Kilauea continues to flow at two places in the park. The vent within Halema'uma'u Crater and the Pu'u'' vent. In conclusion, the trip to the Hawaii Volcanoes National Park should be an experience to remember. On this trip you will experience a cultural, creative, inspirational, and memorable theme. The Park has many visitors each year, to my knowledge the experience is unimaginable.

Six Hawaii Island volcanoes coalesced, or joined, to form the Big Island: Mahukona Volcano, Kohala Volcano, Mauna Kea Volcano, Mauna Loa Volcano, Hualalai Volcano and Kilauea. While Kilauea may be the most famous of the Hawaii Island volcanoes, Mauna Loa and Hualalai are also active volcanoes. To be considered active, a volcano will have erupted at least once in the last 10,000 years, and there continues to be sufficient seismic activity below the surface to suggest that another eruption may occur in the next 1000 years or less. Kohala was devastated by a massive landslide between 250,000 and 300,000 years ago. The Hawaiian

The Mauna Loa volcano is located in Hawaii and means "Long Mountain" in Hawaiian. It is a giant, basaltic shield volcano. It is one of the largest volcanoes and mountains in the world and has been called the "monarch of mountains". It has an estimated volume of 9,600 cubic miles and takes up half the land of Hawaii. It extends about 120 km starting from the southern tip of the island to the northern region. It is 97 km (60 miles) long, 48 km (30 miles) wide, and is 8,742 km (28,680 miles) high from the base on the sea floor to the top. The slopes are steeper than 12 degrees and about 4 degrees at the top of the volcano. Mauna Loa formed about half a million years ago and in the middle stages of forming into a shield volcano where lava flows to form a sloped and broad flat domed volcanic cone. Along with Mauna Kea, the Mauna Loa volcano is responsible for the creation of the Hawaiian Islands. Mauna Loa has erupted thirty-three times since 1843 and is known as one of the most active volcanoes in the world today. The last eruption was 1984 and lava flowed within 4 miles of the city of Hilo. This shows that it is dangerous to live anywhere near Mauna Loa and that it poses as a threat to anyone living near it because it has a very high possibility of erupting within a very short span of time. Below is a picture of Mauna Loa taken from a bird's eye view.
There are many more attractions unique to Hawaii in a different more exciting rather than historical tone. Hawaii is known for their beautiful scenery. A well known and frequently visited location is Hawaii Volcanoes National Park. The park consists of active volcanoes and has viewing areas of lava running down the side of the mountains forming more and more area on the island (“9 Top-Rated Tourist Attractions in
When a volcano erupts, the focus is particularly on the consequences that take place near the volcano, such as weather conditions, the impact on nature, and the people who are affected. The noticeable changes that take place after a volcanic eruption includes the decrease in the temperature, natural disasters, such as tsunamis, droughts, and hurricanes, and the air pollution, which can be harmful to plants, animals, and people.
The earliest outcropping volcanic deposits date back to about 25,000 years ago. The lavas observed at a -1125 m bore-hole are about 0,3-0,5 million years old. It is known for the first eruption of which an eyewitness account is preserved, in 79 AD. Geologically, Vesuvio is unique for its unusual versatility. Its activity ranging from Hawaiian-style release of liquid lava, fountaining and lava lakes, over Strombolian and Vulcanian activity to violently explosive, plinian events that produce pyroclastic flows and surges.
