Past 5 Years Monitoring Data for Mauna Loa Active
Seismic and deformation monitoring data.
Seismic Data
Earthquake Hypocenters Map and Cross Section - Past 5 Years
Above Top: Map showing locations of earthquakes during the past year. Bottom: Depth of earthquakes (circles) during the past five years. 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 earthquakeplot can be found on the HVO Earthquakes page.
Earthquake Rates and Depths - Past 5 Years
Above Top: Number of earthquakes per month during the past five years (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
Global Positioning System - Past 5 Years
Cross-caldera Distance Change
Above: Changes in distance between two GPS stations on opposite sides of MOKUAWEOAWEO, Mauna Loa's summit caldera. Extension across the caldera is often an indication of inflation of the shallow summit magma reservoir.
Summit Vertical Motion
Above: Vertical motion of a GPS station on the southeast side of Mauna Loa's summit caldera. This station is in an area that has historically shown the largest amount of uplift with inflation. An offset in early 2014 is due to an equipment change at the station and is not related to deformation of the volcano.
