All Hawaii volcanoes have their own distinct features. While the entire chain of Hawaiian volcanoes extends more than 3000 miles (nearly 5000 km) across the Pacific Ocean, most have been quiet for hundreds of thousands, even millions of years.
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.
Hawaii volcanoes are known as shield volcanoes due to the characteristic shape they take on as the lava flows outward. This type of volcanic eruption is called a "Hawaiian eruption." The story of how Hawaii Island volcanoes are formed and the creation of the entire Hawaiian Emperor Chain of islands is a fascinating one. Continue reading to learn more...
Mauna Kea Volcano is one of the most interesting Hawaii Island volcanoes. Considered dormant (a sleeping giant), Mauna Kea last erupted about 3,500 years ago. Mauna Kea is the tallest mountain in the world when measured from its base on the sea floor. The Mauna Kea Observatory, the world's largest astronomical research facility, is located at the summit.

Mauna Loa is the largest active volcano in the world. With an elevation of 13,677 feet (4169 meters) above sea level, Mauna Loa stands an impressive 30,077 feet (9167 meters) tall from its base on the ocean floor. It is roughly 3400 feet (1036 meters) shorter than Mauna Kea and second only to Kilauea as the most active volcano on the Big Island, erupting at least 33 times since 1843, most recently in 1984.

Hualalai Volcano is the third most active volcano on the Big Island. Hualalai typically erupts 2-3 times every 1000 years. It's most recent eruption was in 1801. Many homes and resorts have been built on the flanks of this volcano above Kailua-Kona. In 1929, intense earthquake activity beneath the surface, lasting for several weeks, was likely caused by rising magma. Because of this and the fact that it has been over 200 years since its last eruption, Hualalai Volcano is considered a potentially dangerous Hawaii Island volcano that is overdue for an eruption. However, subsurface activity is continuously monitored, and there has been no recent unusual seismicity.
Just northwest of Mauna Kea Volcano, diminutive (relatively) Kohala Volcano is considered extinct, having last erupted 60,000 years ago. Many of the premier Big Island Resorts are built along what is often referred to as the Kohala Coast, although the true coast of the Kohala Volcano is farther to the north.
Of all the Hawaiian volcanoes, only Kilauea Volcano is currently erupting, as it has been doing continuously since January 1983. Most of the flows from the Kilauea eruption have been in a southerly direction from the Pu'u 'Ō'ō spatter cone on Kilauea's summit. But in June, 2014 a new flow began spewing down the northeast flank of Kilauea, and by late October it was threatening the village of Pahoa. That flow has since stopped.
Can you walk out to see lava flow? Can you watch lava flow into the ocean? Your opportunity to view Kilauea's lava flow is inconsistent at best. For years you could almost always count on being able to watch molten lava ooze straight into the ocean. Then it all stopped abruptly in March 2011 when the floor of the Pu‘u ‘O‘o crater collapsed and redirected the flow. Since that time lava flow has been unpredictable.
Of course, things can change at a moment's notice with an active volcano in Hawaii, depending on the whims of Pele, goddess of fire and Hawaiian volcanoes. This Big Island volcano can be very temperamental! Continue reading about Kilauea...
Today's most current information on the Kilauea eruption can be found on the National Park Service website for current conditions. If you are hoping to see actual lava flow during your Hawaii vacation, be sure to check here for updates.
Mahukona Volcano is submerged off the northwest shore, having sunk beneath the ocean and become extinct more than 400,000 years ago. Lava flows from Hualalai Volcano and Kohala volcanoes (along with coral deposits) have buried most of Mahukona Volcano.
Fun for the entire family, Hawaii Volcanoes National Park is a great place to explore and learn more about Kilauea and all the Hawaii Island volcanoes. You can see steam vents and the stunning Kilauea caldera (summit crater), visit the Jaggar Museum on volcanology, and walk through the amazing Thurston Lava Tube. Tons of great hiking too, from easy to strenuous.
Hawaii Volcanoes National Park is located about 50 minutes from Hilo, and about 2-hours from Kailua-Kona.
