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.

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 (GPS)

The plots below show the change in baseline distance between two Global Positioning System (GPS) stations.

UWEV station is located on the northwest edge of Kīlauea's summit caldera. CRIM station is located directly opposite on the southern edge of Kilauea’s summit caldera.

NPOC station is located just north of Pu‘u‘ō‘ō cone on the middle East Rift Zone of Kīlauea. MP3R station is located south of Pu‘u‘ō‘ō cone along the South Flank of Kilauea.

Positive trends in baseline length are associated with an increase in distance between the two station positions, which can typically be interpreted as inflation of the summit magma reservoir or accumulation of magma in the rift zone. .
