Past 5 Years Monitoring Data for Kīlauea

Seismic Data

Earthquake Hypocenters Map and Cross Section - Past 5 Years
Kilauea Earthquakes past 5 years
Kilauea Earthquakes Cross Section past 5 years
Above Top: Map showing locations of earthquakes during the past 5 years. Bottom: Depth of earthquakes (circles) during the past year. Circle-size represents magnitude, and color indicates depth. An interactive earthquake plot can be found on the HVO Earthquakes page.

Earthquake Rates and Depths - Past 5 Years
Kilauea earthquake counts for the past 5 years
Kilauea earthquake depths for the past 5 years
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.

Deformation Data

Map of Selected Deformation Stations


For more information on how electronic tiltmeters and GPS receivers help monitor the deformation of Kīlauea Volcano, see the HVO Deformation page.
Global Positioning System - Past 5 Years

Kīlauea Summit

Kilauea Summit cross-caldera GPS deformation for the past 5 years

Pu‘u ‘Ō‘ō Cone

Puu Oo Cone cross-crater GPS deformation for the past 5 years
Above Top: 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 or Pu‘u ‘Ō‘ō magma storage chamber. Bottom: Change in distance between two station 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.
