U.S. Geological Survey student hydrologic technician Mike Michelotti collects a water-qaulity sample from the Coeur d'Alene River at Rose Lake, Idaho. USGS streamgage 12413810 can be seen in the background. The sample was collected as part of ongoing water-quality monitoring that the USGS conducts in the Coeur d'Alene River basin on behalf of the U.S.

An in-progress piping plover nest on Parramore Island, Virginia -- females typically lay 3 to 4 eggs in a nest over the course of a week. Both the male and female will take turns incubating eggs when the final egg is laid. This nest was established in new overwash habitat created by storms during the winter of 2017-2018. 

Steam rises from fissure 9 on Moku Street in the Leilani Estates Subdivision.

 A lava flow moves on Makamae Street in Leilani Estates at 09:32 am local time, on May 6, 2018.

This map shows the locations, mapped by USGS-HVO scientists, of eruptive fissures in the order that they occurred in the Leilani Estates Subdivision as of 6:00 a.m. HST today (May 6).

This map shows the locations of eruptive fissures on Kīlauea Volcano's East Rift Zone in the order that they occurred in the Leilani Estates Subdivision as of 6:00 a.m. HST today (May 6). The blue lines are paths of steepest descent that identify likely paths of a lava flow, if and when lava moves downhill from an erupting vent.

An intrusion of magma into Kīlauea Volcano's lower East Rift Zone resulted in an eruption in Leilani Estates in the lower Puna District on the Island of Hawai‘i. The first four fissures to erupt in the subdivision are shown here on May 4, emitting copious amounts of hazardous sulfur dioxide gas.

With each large earthquake, ground shaking causes additional collapse within the Pu‘u ‘Ō‘ō crater, sending a plume of reddish-brown ash skyward. The size and vigor of a plume depends on the size of the earthquake and subsequent collapse. This roiling ash plume followed the magnitude-6.9 earthquake on May 4.

This map shows the locations, mapped by USGS-HVO scientists, of the three eruptive fissures in the order that they occurred in the Leilani Estates Subdivision as of 8:00 a.m. HST today (May 4). The fissures are jetting copious amounts of sulfur dioxide gas, which should be avoided.

Kīlauea's summit eruption within Halema‘uma‘u did not initially respond to the volcano's East Rift Zone activity (collapse of the Pu‘u ‘Ō‘ō crater floor and magmatic intrusion into the rift zone) on April 30. But on May 2, the lava lake level began to drop in concert with summit deflation, suggesting that magma was moving from the summit into the East Rift Zone.
