Earthquake Depths - Past 5 Years - Kīlauea

Above Top: Number of earthquakes per month during the past 5 years (blue bars). The red line is the cumulative moment (energy) release. Bottom: Depth of earthquakes during the past 5 years in the area shown on the map above. On both figures, circle-size represents magnitude, and color indicates depth. An interactive earthquake plot can be found on the HVO Earthquakes page.

Global Positioning System - Past 5 Years

Kīlauea Summit

Global Positioning System - Past 5 Years - Kīlauea Summit

Change in distance between two Global Positioning System (GPS) stations located on opposite sides of Kīlauea's caldera. A rapid increase in distance can be interpreted as inflation of the summit magma reservoir. 

Pu‘u ‘Ō‘ō Cone

Global Positioning System - Past 5 Years - Pu‘u ‘Ō‘ō Cone

Change in distance between two stations near Pu‘u ‘Ō‘ō. A rapid increase in distance can be interpreted as inflation of the summit magma reservoir or Pu‘u ‘Ō‘ō magma storage chamber.
