What is the difference between Mauna Loa and Mauna Kea?

Mauna Loa, the biggest volcano on Earth — and one of the most active — covers half the Island of Hawaii.

“The amount of lava actually coming out per unit is actually life threatening.” Trusdell has dozens of graphs showing past lava flows that reached the Ka’u and Kona coastlines within hours. If the next eruption is explosive, ash could drift into the airspace near the Hilo and Kona airports, cutting off flights.

Where is the biggest volcano on Earth?

What is so special about Mauna Kea?

At 13,796 feet above sea level and over 33,000 feet from the bottom of the ocean floor, Mauna Kea is the tallest sea mountain in the world. Mauna Kea’s summit is home to the world’s largest observatory for optical, infrared and submillimeter astronomy.

Is Yellowstone ready to erupt?

Although another catastrophic eruption at Yellowstone is possible, scientists are not convinced that one will ever happen. The rhyolite magma chamber beneath Yellowstone is only 5-15% molten (the rest is solidified but still hot), so it is unclear if there is even enough magma beneath the caldera to feed an eruption.

Is Yellowstone volcano overdue?

The supervolcano under Yellowstone produced three massive eruptions over the past few million years. Each eruption covered much of what is now the western United States in an ash layer several feet deep. The last eruption was 640,000 years ago, but that doesn’t mean the next eruption is overdue.
