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
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”.
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.
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 ...
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.”
With the lava flowing at a rate of 800 to 1,300 gallons per second from vents on the east side zone of Kilauea, more than 500 acres of new land have been added to the island since 1938. The eruption of Kilauea still continues to flow at two places in the park. The vent within Halema'uma'u Crater and the Pu'u 'Ō'ō vent.

(Rubin) Mauna Loa erupting in the near future has to potential to cause extreme mayhem. Scientist fear that Mauna Loa erupting could send the other volcanoes sharing the same hotspot into a triple eruption, which could ultimately threaten the hundreds of thousands of locals and

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
Stories about volcanoes are captivating. Myths come in different versions, but all of them are capable of capturing yours, and everybody’s imagination.
Volcanoes are one of the most destructive forces on Earth. It is estimated that some 500 million people live near active volcanoes (Lutgens and Tarbuck, 2013). Of the Earth's known volcanoes, 70 are expected to erupt each year with at least one large eruption each decade (Lutgens & Tarbuck, 2013). As populations continue to increase and more people are attracted to the beauty surrounding these areas, the immediate threat to humans from these sometimes sleeping giants grows. Due to this, the study of volcanoes and the service that volcanologists provide to the public by way of information and predictions on activity is immeasurable.
There are a few different types of volcanoes, and each erupts a bit differently. Shield volcanoes usually produce a fountain of molten lava that reaches high into the air, anywhere from 10 to 500 meters. In some eruptions, though, there is little fountaining; in these the lava just flows slowly away from the vent. There are also more explosive volcanic eruptions in which the gas pressure builds until it is extremely high and the viscuous lava can no longer stand i...
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).
