Volcano Monitoring by Hawaiian Volcano Observatory

Kīlauea and other active Hawaiian volcanoes are ideal natural laboratories for researching how volcanoes work, because they are easy to access and have frequent eruptions and earthquakes.

Deformation Monitoring Tracks Moving Magma and Faults

Ground deformation measurements provide an important indicator about what is happening beneath a volcano. As magma accumulates in an underground reservoir before an eruption, the ground surface typically swells (named inflation).

Monitoring Volcanic Gas in Hawaii

Gas escapes from magma as it rises toward the surface, erupts, and as it cools and crystallizes below ground.

Geological Monitoring of Hawaiian Eruptions

Geological monitoring involves frequent field visits to active vents and lava flows to observe and document newly created volcanic features and to sample lava or tephra for chemical and mineral analyses.

"Felt" Earthquakes = Ones That People Feel

Residents of Hawaii are accustomed to feeling earthquake shaking. The magnitude, location, and depth of an earthquake, and overlying soil conditions determine how widely and strongly any particular event can be felt. Typically, people report feeling earthquakes larger than about magnitude 3.0.

About Earthquakes in Hawaii

Thousands of earthquakes occur every year in the State of Hawaii. They are caused by eruptive processes within the active volcanoes or by deep structural adjustments due to the weight of the islands on Earth's underlying crust.
