Past 5 Years Monitoring Data for Kīlauea

By Kīlauea

This page presents Kīlauea monitoring data collected over the past five years, including earthquake rates, locations, and depths and ground deformation data.

Seismic Data

Earthquake Hypocenters Map and 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. Depth is reported relative to sea level, which is equal to a depth of zero on the above plot. 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

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. Depth is reported relative to sea level, which is equal to a depth of zero on the above plot. 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. Data plots from additional stations are available from our interactive map. Use the right-side menu to view different types of data.

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

Plot of ground deformation — 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.
