Living with Earthquakes in Hawaii
Tens of thousands of earthquakes occur each year in Hawaii, making it one of the most seismically active places in the United States. Brian Shiro, USGS Hawaiian Volcano Observatory seismologist, talks about the different types of earthquakes in Hawaii and how they are monitored to help forecast volcanic eruptions and recounts the dramatic seismicity that happened during Kīlauea Volcano’s 2018 eruption. Learn about historic damaging earthquakes and seismic hazards in Hawaii, and how you can prepare for the next “big one,” as Brian addresses these topics and more, including how you can participate in the process of earthquake monitoring. This talk was presented as part of the Island of Hawai‘i's 11th annual Volcano Awareness Month. Volcano Awareness Month is spearheaded by the USGS–Hawaiian Volcano Observatory, in cooperation with Hawai‘i Volcanoes National Park, the University of Hawai‘i at Hilo, and Hawai‘i County Civil Defense, and provides informative and engaging public programs about the science and hazards of Hawaiian volcanoes.

Hawaii Volcanoes National Park - Kealakomo (2018)
Hawaiʻi Volcanoes National Park, established on August 1, 1916, is an American national park located in the U.S. state of Hawaii on the island of Hawaii. The park encompasses two active volcanoes: Kīlauea, one of the world's most active volcanoes, and Mauna Loa, the world's most massive shield volcano. The park provides scientists with insight into the birth and development of the Hawaiian Islands, and ongoing studies into the processes of volcanism. For visitors, the park offers dramatic volcanic landscapes, as well as glimpses of rare flora and fauna.
In recognition of its outstanding natural values, Hawaiʻi Volcanoes National Park was designated as an International Biosphere Reserve in 1980 and a World Heritage Site in 1987. In 2012, Hawai'i Volcanoes National Park was depicted on the 14th quarter of the America the Beautiful Quarters series.
On May 10, 2018 the park was closed to the public in the Kīlauea volcano summit area, including the visitor center and park headquarters, due to explosions and toxic ash clouds from Halemaʻumaʻu crater, as well as earthquakes and road damage. However, portions of the park, including the visitor center, reopened to the public on September 22, 2018.
Eruptive activity, ground collapses and explosions in the park ceased in early August. As of late September, the lull in eruptive activity at Kīlauea Volcano continues. At the summit, seismicity and deformation are negligible. Sulfur dioxide emission rates at both the summit and the Lower East Rift Zone are drastically reduced; the combined rate is lower than at any time since late 2007. Earthquake and deformation data show no net accumulation, withdrawal, or significant movement of subsurface magma or pressurization as would be expected if the system was building toward a resumption of activity.
USA - HAWAII - Mauna Loa Volcano
The word “Volcano” comes from the Roman name “Vulcan” – the Roman god of fire.
Volcanic eruption is like a pressure cooker.
The eruption begins with the hot enough temperature to melt the rocks deep inside the earth,
After that, by gas pressure under the surface of the earth, the magma (molten rock) rises toward the surface,
When the magma reaches earth's surface, it is called “Lava”.
Then, Lava flows slow down slope and thicken as they harden on the earth surface.
After the eruptions, volcanoes destroy the miles away on the earth, but then they also create mountains, islands, and, incredibly fertile land.

Hawaii Volcano Air Tour: Mauna Loa and Mauna Kea volcanoes of the Big Island
Cessna Caravan CE-208 cockpit Hawaii volcano air tour view of Mauna Loa and Mauna Kea volcanoes on the Big Island of Hawaii. These are the two largest volcanoes on the island at nearly 14,000 feet above sea level or aprox. 32,000 feet above sea floor rivaling Everest. The entire Volume of Mauna Loa is about 100 X Everest AND is on a 10 year eruption cycle that last went off in 1984 to threaten Hilo town of 35,000!
My name is Buster and I am a Hawaii air tour, interisland charter flight, and flight instructor pilot based at the Kona International Airport PHKO/KOA in Kilua Kona, Hawaii on the Big Island of Hawaii.

Mauna Loa Volcano, Hawaii, 1942
This is from some old footage that belonged to my dad. It is possible that his father took this video, but I tend to think it was a short film that you could probably buy at the time.
Either way, very interesting footage of a powerful volcano - and a nice color view of a world from 70+ years ago.

Hawaii's Kilauea Volcano - Behind the News
There have been some pretty amazing pictures from the island of Hawaii. A volcano there, named Kilauea, has been erupting and spewing out rivers of lava which have destroyed homes and cars. It's pretty scary stuff from a distance, so imagine what it's like for the people who live there. We caught up with some Hawaiian locals and found out more about their fiery mountain.

Hawaii volcano eruption: Volcano Mauna Loa on YELLOW ALERT - What does it mean?
KILAUEA volcano in Hawaii is still erupting more than a month later, and another volcano in the region, Mauna Loa remains under yellow alert. What does the yellow alert on Mauna Loa mean?
Hawaii’s Kilauea is spewing ash and lava, with speeds of the latter reaching up to 17mph.
The volcano remains a danger to life, as citizens are evacuated and any areas of land remain categorised as ‘uninhabitable’.
Kilauea is not the only volcano in the area and the United States Geographical Survey (USGS) has put an alert on another nearby volcano.
Named Mauna Loa, it is the largest active volcano on the planet, and it is on yellow alert.
Hawaii Island Volcanoes
The island of Hawaii is built from five separate shield volcanoes that erupted somewhat sequentially, one overlapping the other. These volcanoes are: Kīlauea, Mauna Loa, Hualālai, Mauna Kea and Kohala.

Mauna Loa
Mauna Loa (/ˌmɔːnə ˈloʊ.ə/ or /ˌmaʊnə ˈloʊ.ə/; Hawaiian: [ˈmɔunə ˈlowə]) is one of five volcanoes that form the Island of Hawaii in the U.S. state of Hawaiʻi in the Pacific Ocean. Mauna Loa is the largest subaerial volcano in both mass and volume, and has historically been considered the largest volcano on Earth. It is an active shield volcano, with a volume estimated at approximately 18,000 cubic miles (75,000 km3), although its peak is about 120 feet (37 m) lower than that of its neighbor, Mauna Kea. The Hawaiian name Mauna Loa means Long Mountain. Lava eruptions from Mauna Loa are silica-poor, and very fluid; eruptions tend to be non-explosive and the volcano has relatively shallow slopes.
Mauna Loa has probably been erupting for at least 700,000 years, and may have emerged above sea level about 400,000 years ago. The oldest-known dated rocks are not older than 200,000 years. The volcano's magma comes from the Hawaii hotspot, which has been responsible for the creation of the Hawaiian island chain over tens of millions of years. The slow drift of the Pacific Plate will eventually carry Mauna Loa away from the hotspot within 500,000 to one million years from now, at which point it will become extinct.

Quakes on Mauna Loa and Kīlauea in 2019
Geophysicist Brian Shiro of the USGS-Hawaiian Volcano Observatory joins us to discuss earthquakes on the most active Hawaiian volcanoes during 2019. Topics include:
- Status and historical context of Mauna Loa's seismicity before prior eruptions (and non-eruptions)
- Deep earthquakes and tremor under Pāhala
- Continued motion under Kīlauea's south flank
- Mechanics of big earthquakes and theoretical limits
- Earthquake preparedness and what to do during the shaking
- The Great Hawai‘i ShakeOut event in October, including a PSA by The Rock

Mauna Loa is one of five volcanoes that form the Island of Hawaii in the U.S. state of Hawai‘i in the Pacific Ocean. The largest subaerial volcano in both mass and volume, Mauna Loa has historically been considered the largest volcano on Earth. It is an active shield volcano with relatively gentle slopes, with a volume estimated at approximately 18,000 cubic miles (75,000 km3), although its peak is about 120 feet (37 m) lower than that of its neighbor, Mauna Kea. Lava eruptions from Mauna Loa are silica-poor and very fluid, and they tend to be non-explosive.
Mauna Loa has probably been erupting for at least 700,000 years, and may have emerged above sea level about 400,000 years ago. The oldest-known dated rocks are not older than 200,000 years. The volcano's magma comes from the Hawaii hotspot, which has been responsible for the creation of the Hawaiian island chain over tens of millions of years. The slow drift of the Pacific Plate will eventually carry Mauna Loa away from the hotspot within 500,000 to one million years from now, at which point it will become extinct.
Mauna Loa's most recent eruption occurred from March 24 to April 15, 1984. No recent eruptions of the volcano have caused fatalities, but eruptions in 1926 and 1950 destroyed villages, and the city of Hilo is partly built on lava flows from the late 19th century. Because of the potential hazards it poses to population centers, Mauna Loa is part of the Decade Volcanoes program, which encourages studies of the world's most dangerous volcanoes. Mauna Loa has been monitored intensively by the Hawaiian Volcano Observatory since 1912. Observations of the atmosphere are undertaken at the Mauna Loa Observatory, and of the Sun at the Mauna Loa Solar Observatory, both located near the mountain's summit. Hawaii Volcanoes National Park covers the summit and the southeastern flank of the volcano, and also incorporates Kilauea, a separate volcano.
