Did you know, maps can help one if they are moving near an active volcano? Mauna Loa is the biggest shield volcano in the world and the lava flow is devastating. A thermal map can let people know when to evacuate. Mauna Loa has been erupting since 1832 and an elevation map will tell when and if lava is coming to destroy.
A Shield Volcano
Mauna Loa is a shield volcano. Mauna Loa, “is a gently sloping mountain produced from a large number of generally very fluid lava flows” (Mauna Loa Volcano). Also an elevation map can show how high and wide the volcano is. According to Britannica, Mauna Loa is 64 miles (103 km) wide. As a result, this can be seen on an elevation map because, one can see how far it goes down. Mauna Loa is the largest gently sloping mountain in the world.
How Many Eruptions? Mauna Loa has erupted 39 times. “According to USGS estimates, the volcano has erupted an average of once every 6 years over the past 3,000” (Mauna Loa Volcano). As a matter of fact, a thermal map helps warn scientists if it’s about to erupt. “Mauna Loa’s most recent eruption occurred from March 24th to April 15th, 1984” (Wikipedia). A thermal map would help scientists to see if there is a change in temperature. Since 1832, eruptions from Mauna Loa have occurred 39

According to USA Today, “In 1950, the eruption of Mauna Loa sent voluminous amounts of lava downslope through small villages in upper Ho’okena, destroying homes, a gas station, lodge, church and a cemetery.” The lava would be concerning to people because in the event that their homes are destroyed, they wouldn’t have a place to live. “The village of Kapoho was entirely destroyed during the 1960 eruption in the lower east rift (fissure) zone of Kilauea” (NOAA Geologic Hazards). A population map would be helpful to have for first responders so they know how many people to evacuate in emergencies. Mauna Loa eruption cause great danger for
Many of us know Mount Shasta to be a beautiful mountain and a popular tourist location in California. However, this mountain is much more than that, this mountain is actually a volcano. Volcanoes come with a number of hazards and a volcano of this size is of no exception. Previous eruptions on Mount Shasta have given us an idea of the power this volcano has and the damage it may do. With this information scientists are able to predict what may happen should another explosion occur.
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 ...
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
In March 18, 1880 Mount St. Helens there was a catastrophic eruption that caused a huge volume of ash; the ash plume would be over central Colorado within 16 hours. After years of dedicated monitoring (knowing where to volcano is, unlike an earthquake not knowing exactly where this geological even is exactly) there was been increasing accuracy in forecasting eruptions.
Stories about volcanoes are captivating. Myths come in different versions, but all of them are capable of capturing yours, and everybody’s imagination.
Mount Bona and Mount Churchill is one of the greatest mountains in Alaska. Also it is the fifth highest independent peak in the United States. The eruption occurred around 800 AD in Wrangell-St. Elias National Park Alaska, U.S. This two volcanoes is more than 15,000 feet high, and permanently covered with ice and snow. Also 1250 years ago, Mount Churchill erupted which blew the lid off the mountain, and carried the ash into the southwest Yukon. It called White River Ash, and it covers almost 600,000 square kilometers in Alaska, the Yukon, and the Northwest Territories. If you was closer to the volcano you will be dead because the ash can be 60cm thick. This is very dangerous. Do you know that Mount Bona named by Prince Luigi Amedeo, Duke of the Abruzzi in 1897.
Maunaloa last erupted in 1938 and Kilauea has been erupting since January 3,1938. The Hawaii Volcanoes National Park was named a World Biosphere site by UNESCO in 1987. Kilauea is also called the world's only drive-in volcano.
Currently Mauna Loa is highly monitored by The USGS Hawaiian Volcano Observatory (HVO). Although scientist cannot determine the exact time and place of an approaching eruption, there is no doubt that Mauna Loa will erupt again. In an HVO press release on March 26, 2009, Frank Trusdell, an HVO geologist who has studied Mauna Loa for decades quoted “Mauna Loa will erupt again, and there’s a good chance that it will be during this lifetime.”
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.
Living in the Midwest, we don’t really think about volcanos. But, we actually live about 1000 miles from an active volcano that is overdue for a massive eruption. Scientists call this volcano a Supervolcano, “a supervolcano is any volcano capable of producing a volcanic eruption with an ejecta volume greater than 1,000 km3 (240 cu mi). This is thousands of times larger than normal volcanic eruptions.”
I. Introduction Volcano: defined is a mountain or hill formed by the accumulation of materials erupted through one or more openings (called volcanic vents) in the earth's surface. The term volcano can also refer to the vents themselves. Most volcanoes have steep sides, but some can be gently sloping mountains or even flat tablelands, plateaus, or plains. The volcanoes above sea level are the best known, but the vast majority of the world's volcanoes lie beneath the sea, formed along the global oceanic ridge systems that crisscross the deep ocean floor. According to the Smithsonian Institution, 1511 above-sea volcanoes have been active during the past 10,000 years, 539 of them erupting one or more times during written history. On average, 50 to 60 above-sea volcanoes worldwide are active in any given year; about half of these are continuations of eruptions from previous years, and the rest are new. Mount St. Helen Volcanic eruptions in populated regions are a significant threat to people, property, and agriculture. The danger is mostly from fast-moving, hot flows of explosively erupted materials, falling ash, and highly destructive lava flows and volcanic debris flows. In addition, explosive eruptions, even from volcanoes in unpopulated regions, can eject ash high into the atmosphere, creating drifting volcanic ash clouds that pose a serious hazard to airplanes. II. Volcano Formation All volcanoes are formed by the accumulation of magma which is molten rock that forms below the earth's surface. Magma can erupt through one or more volcanic vents, which can be a single opening, a cluster of openings, or a long crack, called a fissure vent. It forms deep within the earth, generally within the upper part of the mantle which is one of the layers of the earth's crust, or less commonly, within the base of the earth's crust. High temperatures and pressures are needed to form magma. The solid mantle or crustal rock must be melted under conditions typically reached at depths of 50 to 60 mi. (80 to 100 km) below the earth's surface. Once tiny droplets of magma are formed, they begin to rise because the magma is less dense than the solid rock surrounding it. The processes that cause the magma to rise are poorly understood, but it generally moves upward toward lower pressure regions, squeezing into spaces between minerals within the soli...
All of these evidences are still being compiled and scrutinized in order to verify the true relation between volcanic eruptions and climate change. Works Cited: Angell, James.

The volcano that poses the greatest threat to humanity today is Mount Rainier because of its proximity to highly dense populations, its potential to erupt, and how it can spread disaster. Mount Rainier is categorized as a composite volcano, and it is also one of sixteen Decade Volcanoes in the world. Decade Volcanoes are under close watch by committees and disaster services because of their great potential to cause catastrophic disasters in the area in which they lie (National Park Service [NPS]). Mount Rainier sits next to the large cities of Tacoma, Seattle, and their suburbs, and they are all in distance of the potential danger of the volcano (Driedger and Scott, 2008). The volcano also relies on its drainage system, the Columbia River, to spread disaster, so parts of Oregon and southwestern Washington are also unsafe from the danger of a Mount Rainer eruption (NPS). Mount Rainier’s eruption potential is also what makes it such a dangerous volcano. Geothermal activity of the volcano indicated that it is still active, and it is in between its eruption cycle (NPS, Driedger and Scott, 2008). Scientists think a Mount Rainier eruption will be less explosive than in past events, but because of the
Findings: When the volcano erupts the prefectures of Shizuoka, Yamanashi and Kanagawa will be affected. These prefectural governments created evacuation plans that call for 750,000 people to leave their homes in Shizuoka and Yamanashi. In addition another 470,000 people will need to evacuate in Kanagawa because of volcanic ash in the air. There is still 8.85 million people who live in the areas of the three prefectures where 2 cm or more of volcanic ash is expected. These peoples health will be affected due to the ash. There will be massive destruction after the er...
Japan offers a wide variety of volcanoes. “The islands of the Japanese archipelago occupy one of the most concentrated areas of seismic and volcanic activity in the world” (Gates and Ritchie, p. 127). Though the volcanoes of Japan can be very deadly, many are tourist attractions. Mount Fuji, for example, and the numerous hot springs that occur due to volcanic activity are often visited. However, the calderas and volcanoes of this region still cause problems to the people and places of Japan (Gates and Ritchie, p. 127-128).
