Past Week Monitoring Data for Kīlauea

Seismic Data

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

Earthquake Rates and Depths
Kilauea earthquake counts for the past week
Kilauea earthquake depths for the past week
Above Top: Number of earthquakes per day during the past week (blue bars). The red line is the cumulative moment (energy) release. Bottom: Depth of earthquakes during the past week 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.
Electronic Tilt at Kīlauea Summit and East Rift Zone - Past Week
Kilauea Summit and East Rift Zone Tilt for the past week
Above: The blue line shows the radial tilt at Uwēkahuna (UWE), on the northwest rim of Kīlauea's caldera. The green line is radial tilt at Pu‘u ‘Ō‘ō (POC), on the north flank of Pu‘u ‘Ō‘ō cone. These are recorded by continuously operating electronic tiltmeters. Positive changes often indicate inflation of the magma storage areas beneath the caldera or Pu‘u ‘Ō‘ō, but may also result from heavy rainfall or, occasionally, instrumental malfunctions.
