Radar Images, May 5-June 18

Thanks to the Italian Space Agency for taking a radar satellite image of Kilauea about once a week:

USGS: “May 5 and June 18 at about 6:00 a.m.[…]The last five images in the sequence, from May 29-June 18, show the development of several cracks outside Halema‘uma‘u (also seen in recent UAS footage of the crater) and inward slumping of a large portion of the western, southwestern, and northern crater rim. Much of this motion appears to be coincident with the small explosions from the summit that have taken place on a near daily basis over the past 3 weeks.” (Full-sized)
Yes, HVO and the Jaggar Museum have evacuated, and artwork has been moved to safety.
