Past Month Monitoring Data for Kīlauea
Earthquake Hypocenters Map and Cross Section - Past Month
Above Top: Map showing locations of earthquakes during the past month. Bottom: Depth of earthquakes (circles) during the past month. 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 Month
Above Top: Number of earthquakes per day during the past month (blue bars). The red line is the cumulative moment (energy) release. Bottom: Depth of earthquakes during the past month 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.
