Past Week Monitoring Data for Kīlauea

Active
By Kīlauea November 5, 2024

This page presents Kīlauea monitoring data collected over the past week, including summit crater floor elevation, earthquake rates, locations, and depths, and ground deformation data. 

Halemaʻumaʻu crater floor elevation

Graph showing elevation above sea level data for the past week of Halema‘uma‘u crater, at Kīlauea volcano's summit. This data is measured with a laser rangefinder instrument that was installed on January 8, 2021. The fixed instrument continuously measures the distance to a location on the western crater floor 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.

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.

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 station UWD near Uēkahuna, on the western rim of Kīlauea's summit caldera. The green line is radial tilt at station POC, located on the north rim of Pu‘u‘ō‘ō cone on the middle East Rift Zone of Kīlauea. These are recorded by continuously operating electronic tiltmeters. Positive changes often indicate inflation of the magma storage areas beneath the caldera or middle East Rift Zone region, but may also result from heavy rainfall or, occasionally, instrumental malfunctions.
