Pre- and post-fire images acquired with shortwave infrared (SWIR), near infrared (NIR), and red bands on Landsat 8’s Operational Land Imager sensor reveal a significant, 14,442-acre burn scar within the park’s high country. The burn scar appears red in the June 23 image.

Though difficult to photograph, aerial views showed that this open vent was but a small window into a large, hot cavity beneath Puʻu ʻŌʻō's northeast flank in Hawaii Inside, streams of lava from an unseen source (or sources) closer to the crater rim (visible at lower right) were cascading toward the upper left into unknown depths.

The red-footed booby is a seabird that ranges across tropical oceans of the world, including Hawaiʻi. And yes, these boobies do have startlingly bright red feet set off by their awesome blue bills. This bird is nesting at Kīlauea Point National Wildlife Refuge, an important seabird breeding site on Kauaʻi.

Nearly 60 years after a magnitude 7.7 earthquake struck Lituya Bay, Alaska — leading to a tsunami that devastated the area — six U.S. Geological Survey geologists revisited the isolated region of Alaska, to pick up where their scientific predecessors left off.
