Volcanic Activity and Geology of Hawaii

Hawaii Volcanoes National Park on the Island of Hawaii offers a unique opportunity to observe active volcanoes, including Kilauea and Mauna Loa. Kilauea is one of the world's most active volcanoes, with continuous eruptions since 1983. The park provides access to volcanic landscapes, allowing visitors to witness geological changes and lava flows. Scientists study these processes to understand volcanic activity. A new island, Loihi, is forming southeast of Hawaii, highlighting the ongoing volcanic activity that shapes the Earth.

What recent event at the Kilauea volcano serves as a reminder of its ongoing activity?

• A new hiking trail opening

• The first explosive eruption in over 80 years

• The construction of a visitor center

• A new species discovery

What makes Mauna Loa unique compared to other volcanoes?

• It is the world's most massive volcano when measured from the ocean floor

• It is the oldest volcano on Earth

• It is the tallest mountain in the world

• It is the most active volcano

How has Kilauea's activity since 1983 affected the Big Island?

• It has reduced the island's size

• It has added over 550 acres to the island

• It has caused the island to sink

• It has had no impact on the island's size

Why is Kilauea considered a unique opportunity for geologists?

• It is the only volcano in the world

• Its eruptions are predictable

• It is located in a remote area

• Its ongoing eruptions and accessibility allow for close observation

What is the role of lava tubes in Kilauea's volcanic activity?

• They are used for tourist attractions

• They transport lava to the ocean

• They prevent eruptions

• They store water

What do volcanologists monitor to understand Kilauea's activity?

• Weather patterns

• Animal behavior

• Chemical changes in lava samples

• Tourist numbers

What unique experience does the South flank of Kilauea offer to visitors?

• A chance to see extinct volcanoes

• A view of the oldest land on Earth

• Unprecedented access to drive around the summit and caldera

• A chance to swim in lava

What is Loihi, and what is its significance?

• A tourist attraction

• A potential new island forming southeast of Hawaii

• A dormant volcano

• A type of lava flow

How long is it predicted to take for Loihi to surface?

• 500,000 years

• 50,000 years

• 100,000 years

• 250,000 years

What percentage of the Earth was created by volcanic processes?

• 80%

• 70%

• 60%

• 50%
