Why do some Hawaii earthquakes occur so far offshore?
Why do some Hawaii earthquakes occur so far offshore?Many of the earthquakes in Hawaii that extend offshore and up the island chain are due to plate bending, or flexure. The upper panel shows magnitude-5 and greater earthquakes since 1861, with some notable events labeled.

Kīlauea Volcano's Lower East Rift Zone
An Unmanned Aircraft Systems overflight of fissure 8 on August 21, 2018, showed no incandescence within the cinder cone. Minor amounts of gases, primarily steam, rose from the north wall of the cinder cone and from areas along the lower East Rift Zone.

7 months of no lava at Pu‘u ‘Ō‘ō heralds end of an e
7 months of no lava at Pu‘u ‘Ō‘ō heralds end of an ePu‘u ‘Ō‘ō on May 3, 2018, as viewed from the helicopter overflight. The crater floor is collapsed, and a thin plume escapes from the gaping crater. The west flank cracked on April 30th around 2:30 pm HST, and minor amounts of lava oozed out of the crack (line of steaming features) just before the plumbing system catastrophically failed.

Changes Over Time at Kīlauea (April - August 2018)
Changes Over Time at Kīlauea (April - August 2018)Changes at the summit of Kīlauea between April 14 and August 20, 2018, were captured by a USGS–Hawaiian Volcano Observatory camera. This time-lapse series includes roughly one image per day. The lava lake within Halema‘uma‘u is visible in April, with overflows onto the caldera floor on April 23.

Checking out the Gobies While Sampling
The camera glances at the bottom of the boat above and then pans down to the lake bottom. The lake bottom is covered in tons of round gobies swimming around in and out of the cladophora. Again the camera pans up to show a diver and the dive camera completing a transect in the distance.

InSAR image of Yellowstone spanning 2004-2006
Color bands in this radar interferogram depict the pattern of surface deformation at the Yellowstone caldera from September 22, 2004, to August 23, 2006. The southwest and northeast parts of the caldera floor rose about 11 cm (4.3 inches) and 15 cm (5.9 inches), respectively, while the north caldera rim near Norris Geyser Basin subsided about 7 cm (2.8 inches).
