Two shapefiles are associated with each mapping date: a polyline shapefile for the lava flow contacts with their attributes, and a polygon shapefile for the full extent of the lava flow on that date.In total, this dataset contains 28 shapefiles with associated metadata for 14 separate mapping dates. Episode 61g began with a breakout from the east flank of Pu‘u ‘Ō‘ō on May 24, 2016. G., 2017, GIS shapefiles for Kīlauea's episode 61g lava flow, Pu‘u ‘Ō‘ō eruption: May 2016 to May 2017: U. Geological Survey data release, https://doi.org/10.5066/F7DN43XR. This dataset contains shapefiles and associated metadata for Kīlauea volcano's Pu‘u ‘Ō‘ō episode 61g lava flow from May 24, 2016 through May 31, 2017. One of the most active is fissure 22, which has shed enough lava to create a channel that extends all the way to Hawaii’s southeastern coast.The Operational Land Imager (OLI) on Landsat 8 acquired the data for this false-color view of the lava flow as it appeared on the night of May 23, 2018.In the coming weeks, magma may continue to emerge from new fissures or slip back and forth between existing fissures.

Lava reached the Pacific Ocean at Kamokuna on July 26, 2017, and began building a lava delta that extended seaward from the original coastline.

Recall that atoms are the basic building blocks of matter.

Atoms are made up of much smaller particles called protons, neutrons, and electrons.

Scientists use a technique called radiometric dating to estimate the ages of rocks, fossils, and the earth.

Many people have been led to believe that radiometric dating methods have proved the earth to be billions of years old.
