In this photo, USGS scientists Megan Haserodt (Hydrologist) and Jenelle Wempner (Student Intern) install a double ring infiltrometer along a recreated floodplain of Underwood Creek, a tributary to the Milwaukee River and Lake Michigan in Milwaukee, Wisconsin. The work is part of a larger study of how overbank flows and shallow groundwater in floodplains are connected for

Summit Vertical Motion - Past 5 Years Mauna Loa. 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.

Cross-caldera Distance Change - Past 5 Years Mauna Loa. Changes in distance between two GPS stations on opposite sides of Moku'āweoweo, Mauna Loa's summit caldera. Extension across the caldera is often an indication of inflation of the shallow summit magma reservoir.

Earthquake Depths - Past 5 Years Mauna Loa. 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.

Earthquake Rates - Past 5 Years Mauna Loa. Number of earthquakes per month during the past five years (blue bars). The red line is the cumulative moment (energy) release.

Earthquake Hypocenters Cross Section - Past 5 Years Mauna Loa. Depth of earthquakes (circles) during the past five years. Circle-size represents magnitude, and color indicates depth.

Change in distance between two stations near Pu‘u ‘Ō‘ō. A rapid increase in distance can be interpreted as inflation of the summit magma reservoir or Pu‘u ‘Ō‘ō magma storage chamber.

Change in distance between two Global Positioning System (GPS) stations located on opposite sides of Kīlauea's caldera. A rapid increase in distance can be interpreted as inflation of the summit magma reservoir.

Sulfur dioxide (SO₂) emission rates measured using an upward-looking ultraviolet spectrometer. These data are collected by traversing the gas plume in a vehicle, downwind of Halema‘uma‘u, generally within and south of Kīlauea Caldera. Results from multiple traverses during a day are averaged to yield the emission rates shown here. Successful measurements depend
