[MOcam] Mokuʻāweoweo Caldera from South Rim

This image is from a research camera positioned on the south rim of Mokuʻāweoweo, Mauna Loa's summit caldera, in Hawaiʻi Volcanoes National Park. The camera looks north-northwest, focusing on the southern part of the caldera. The 1940 cone is just right of center; the 1949 cone is on the caldera rim at left. The high point of Mauna Loa's summit is in the background.

Endangered Hawaiian Hoary Bat

An endangered Hawaiian hoary bat, a species that is sometimes killed by wind turbines. USGS scientists from Hawaii and Colorado are devising a way to directly observe bat occurrence and behavior at wind turbines using a video system composed of high-powered illuminators and near-infrared cameras.  This new approach images the full rotor-swept areas of wind turbines for

Slope map of Mauna Loa, including lava flows erupted since 1823 (gray), showing the approximate number of hours or days it took for a flow to advance from the vent location to the ocean or maximum reach of a flow. One flow that moved down the steep slopes on west flank of Mauna Loa reached the ocean in as little as 3 hours after the vent started erupting in 1950. The bold

Starting about 1:31 Sunday morning, September 12, a swarm of small earthquakes and associated volcanic tremor began at Kīlauea Volcano.

In our efforts to refine the geologic map of Haleakalā, we recently obtained radiocarbon ages from the youngest lava flows, those at La Perouse Bay. The ages indicate these flows were emplaced sometime between A.D. 1480 and 1600.

The Hokule`a set sail from Hilo in June on an eight-month round-trip voyage to Rapa Nui (Easter Island). The crew of this double-hulled sailing canoe is using traditional Polynesian star-compass navigation to find the island, which is about 2,200 km (1,400 mi) from the nearest inhabited land mass.

The August 17, 1999, magnitude 7.4 earthquake in Turkey leveled thousands of buildings and resulted in over 10,000 deaths. This was the largest earthquake in western Turkey in this century, but it was just the latest in a series of destructive earthquakes from the North Anatolian fault.

In the wild west of the 19th century, stagecoaches often had someone aboard whose job was to warn and protect the driver from marauding gangs and wild animals. This job, termed "riding shotgun," still exists but in various forms and degrees of sophistication.

Kīlauea Volcano has been erupting nearly continuously for the past 6,068 days since activity started on January 3, 1983. Lava first entered the ocean on November 28, 1986 and except for brief pauses in eruptive activity, has been constantly flowing into the sea.

How long do explosive periods last at Kīlauea? Early researchers concluded that the Keanakako`i Ash—the rocky deposits on the ground surface around Kīlauea caldera—was formed by many ex-plosions during several centuries ending in A.D. 1790, the known date of a large explosive eruption.

All of sudden, there's an earthquake...or was it an earthquake? Where was it? How big was it? Does it signal the start of an eruption or magma shifting its position within the volcano? Is there a possibility of a tsunami produced by this earthquake?

On Friday, March 27, 1868, at 5:30 a.m., several whaling ships anchored in Kawaihae Harbor noticed a dense column of fume reflected by a bright light southwest of the summit of Mauna Loa.

The islands of the Pacific are some of the most isolated in the world and have produced distinct floras and faunas. Endemism, whereby plants and animals are restricted to a single geographic area, is frequent. Hawai`i exemplifies this process.

A highly endangered native Hawaiian bird species has taken a small but significant step back from the brink of extinction. USGS biologists monitoring 14 captive-reared puaiohi released into the wild earlier this year by The Peregrine Fund say the birds are nesting and have already fledged four young.

Visitors to the Big Island's southeast coast commonly see a steam plume, the telltale sign that Kīlauea's eruption is sending lava into the ocean.
