Past Week Monitoring Data for Kīlauea

Depth of Lava Lake

graph showing the depth of the lava lake for the past week

Graph showing the depth of the Halema‘uma‘u crater lava lake at Kīlauea Volcano's summit for the past week. On January 8, 2021, a novel laser rangefinder was stationed at Kīlauea Volcano's summit. The fixed instrument continuously measures the distance to a location on the western lava lake surface, and telemeters data to HVO in real time. The raw data has been edited for this graph, with a running mean average filter of 3600 seconds. Variations in plotted depth can occur due to laser rangefinder returns on gas rather than the lava surface.

Locations and depths of earthquakes during the past week

Earthquake Depths - Past Week Kilauea

Above Top: Map showing locations of earthquakes during the past week. Bottom: Depth of earthquakes (circles) during the past week. 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 Depths - Past Week Kilauea

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. 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

Electronic Tilt at Kīlauea Summit and East Rift Zone - Past Week

Electronic Tilt at Kīlauea Summit and East Rift Zone - Past Week

The blue line shows the radial tilt at Uwekahuna station (UWE), on the western rim of Kīlauea's caldera. The green line is radial tilt at Pu‘u ‘Ō‘ō (POO), north 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.
