Less than 1/10 of a mile southwest from Hilina Pali road is a small patch of bare ground, the parking spot for the unmarked Devils Throat collapse crater. Devils Throat is an excitingly vertically-sided pit crater that is worth the visit just for the okole squeezing peering down the throat will give you. An approximately 50 meter trail leads south east from the road along a prominent earth fracture to the 30 meter wide by 55 meter deep pit. Keep your eyes on the trail in front of you at all times as you approach. Do not allow children or exuberant adults run ahead, especially in the dark, fog or vog, as there are NO safety rails and absolutely NO warning the crater is coming up; one simply arrives, teetering, at the brink. Be extremely careful approaching the crater rim, as the edge is very unstable and prone to collapse. Viewing and photography are best done here when the sun is high in the sky and the walls and bottom of the crater are not in shadow.Produced by Donald B.

Lōihi Seamount is an active volcano built on the seafloor south of Kilauea about 30 km from shore. The seamount rises to 969 m below sea level and is marked by a caldera-like depression 2.8 km wide and 3.7 km long. Three collapse pits or craters occupy the southern part of the caldera; the most recent pit formed during an intense earthquake swarm in July-August 1996. Named Pele's Pit, the new crater is about 600 m in diameter and its bottom is 300 m below the previous surface! Like the volcanoes on the Island of Hawaii, Lōihi has grown from eruptions along its 31-km-long rift zone that extends northwest and southeast of the caldera. During July and early August, 1996, the largest swarm of earthquakes ever observed at any Hawaiian volcano occurred at Lōihi Seamount. In response to this event, an initial cruise was dispatched to Lōihi in early August, and two previously planned cruises sailed in September and October on the R/V Kaimikai-O-Kanaloa (KOK). Calm weather and a newly refurbished ship combined to provide excellent conditions for documenting the volcanic, plume, vent, and biological activity associated with this swarm. These cruises conducted a total of 15 PISCES V submersible dives, 41 water sampling operations, and 455 km of SeaBeam surveys, and deployed 40 sonobuoys and one ocean bottom seismometer (OBS). The most obvious result of the activity was the formation of a large summit pit crater similar to those observed at Kilauea. Greatly expanded hydrothermal <b>...</b>

EN: Friday January 07, 2011 some small explosions, followed by weak ash emissions, occurred at the Pit-Crater on the eastern side of the SouthEast Crater cone. The sound of the explosions was loud enough to such an extent to be heard from several km. The activity at the summit of Mt Etna in this moment is unpredictable, you shouldn't get too close because a possible strong explosion could be very dangerous. ------------------------------------------------------------------------------------------- IT: Venerdì 7 gennaio 2011 alcune piccole esplosioni, seguite da deboli emissioni di cenere, sono avvenute presso il Pit Crater sul lato orientale del cono del Cratere di Sud-est. Il suono delle esplosioni era abbastanza forte al punto tale da essere udito a diversi km di distanza. L'attività presso la zona sommitale del monte Etna in questo momento è imprevedibile, è sconsigliabile avvicinarsi troppo, perché una eventuale esplosione più forte delle altre potrebbe verificarsi improvvisamente ed essere molto pericolosa. ------------------------------------------------------------------------------------------------ Shooting & Video Editing by Marco Di Marco.

Hiking to Maka'ophui Crater on the Big Island of Hawaii on June 23rd, 2010. The trail winds through a ravaged landscape from past volcanic flows, passing a small pit crater, a shield volcano (Mauna Ulu), and steam vents. Maka'opuhi Crater is the largest pit crater on Kilauea. It is ~360 ft. deep and 1.6 km by 1 km. The distance of the hike was 8 miles round trip. Island Trails KaleoLancaster.blogspot.com

Written and Produce by Donald B MacGowan Narrated by Frank Burgess Video and still photography by Donnie MacGowan and Frank Burgess Following along Kilauea's East Rift Zone, Chain of Craters Road passes through an amazing array of rift volcanoes, pit craters, lava trenches and flow fields. Leaving Crater RIM Drive at the Devastation Trail parking lot, Chain of Craters Road traverses and opens-up some of the most wild and beautiful landscapes seen anywhere, terminating near the active lava flows from Kilauea Volcano. Perhaps nowhere else on earth are the elements high mountains, wild seascapes and active volcanoes and their lava flows more dramatically displayed. Crazily switching-back repeatedly down the Holei Pali, Chain of Craters Road finally reaches the untamed and scenically wild coastline, where giant waves spray and spume over sea cliffs dozens of feet high. Towering steam plumes in the distance at the end of the road mark where unimaginably hot liquid rock pours into the wild, wild sea. A place of mystery, a place of power, a place of wonder. Altogether, Chain of Craters Road is a singular and essential addition to any visit to the Island of Hawai'i. Once connecting Volcano Village through the Park to Puna and State Routes 130 and 137 at Kalapana, Chain of Craters Road has repeatedly been badly damaged by earthquake, buried in lava, re-routed and re-built and broken up and buried again. The current eruption, which began in 1983, has buried a significant portion of <b>...</b>

December 2009. Music by: François De Roubaix. The centerpiece of Hawaii Volcanoes National Park is the 11-mile Crater Rim Drive that circles Kilauea's summit caldera. If you only have a few hours in the park, this is a good way to hit the main attractions. While circling the Kilauea cladera, this road passes through rainforest and desert, while providing access to numerous well-marked scenic stops and short walks. On the drive around the summit caldera, you will encounter sulphur banks, steam vents, pit craters, lava flows from eruptions in 1974 and 1982, areas recovering from the cinder fallout of the 1959 eruption, a walk through an underground lava tube, the Jaggar Museum, Halema'uma'u Crater, Devastation Trail, Kilauea Iki Crater, and the Thurston Lava Tube.

In the broadest sense, the term impact crater can be applied to any depression, natural or manmade, resulting from the high velocity impact of a projectile with larger body. In most common usage, the term is used for the approximately circular depression in the surface of a planet, moon or other solid body in the Solar System, formed by the hyper-velocity impact of a smaller body with the surface. This is in contrast to the pit crater which results from an internal collapse. Impact craters typically have raised rims, and they range from small, simple, bowl-shaped depressions to large, complex, multi-ringed impact basins. Meteor Crater is perhaps the best-known example of a small impact crater on the Earth. Impact craters provide the dominant landforms on many solid Solar System objects including the Moon, Mercury, Callisto, Ganymede and most small moons and asteroids. On other planets and moons that experience more-active surface geological processes, such as Earth, Venus, Mars, Europa, Io and Titan, visible impact craters are less common because they become eroded, buried or transformed by tectonics over time. Where such processes have destroyed most of the original crater topography, the terms impact structure or astrobleme are more commonly used. In early literature, before the significance of impact cratering was widely recognised, the terms cryptoexplosion or cryptovolcanic structure were often used to describe what are now recognised as impact-related features on <b>...</b>

Video view 1 of 6 Total overview of the crater. The Darvaza area is rich in natural gas. While drilling in 1971 geologists accidentally found an underground cavern filled with natural gas. The ground beneath the drilling rig collapsed, leaving a large hole with a diameter of about 50-100 meters. To avoid poisonous gas discharge, it was decided to burn the gas. Geologists had hoped the fire would go out in a few days but it has been burning ever since. Locals have named the cavern The Door to Hell. Next to capturing the gas, flaring is safer and friendlier to the environment than releasing the methane into the atmosphere as methane is a relatively potent greenhouse gas with a high global warming potential of 72 (averaged over 20 years) or 25 (averaged over 100 years).

E' stato il ventesimo evento parossistico dal 12 gennaio 2011, quando ancora quell'enorme cono nato durante queste eruzioni lampo lo chiamavamo "Pit-Crater". Come ogni evento ha mostrato un attività unica e particolare, in questo caso ad evidenziare il fattore unicità è stata la fase anticipatoria, durata ben 12 giorni e la durata dell'evento: complessivamente 12 ore. Ma a prescindere dalle caratteristiche vulcaniche di questo parossismo, la sua esclusività in questo caso è stata dovuta alle condizioni metereologiche. In questi giorni in cui il gelo è diventato quasi un emergenza in tutta Italia, sull'Etna la neve è caduta abbondante fino ai fianchi più distanti dalla vetta. In molti casi le strade sono state bloccate ed è una difficoltà salire. Ma il candido vestito bianco che ha indossato, è servito a riflettere la luce della Luna, che ha fatto brillare il suo manto bianco che ha preso a brillare nel buio. Ben visibile la forma dei crateri sommitali, il cono del Cratere di Sud-Est completamente gelato, la colonna di gas sempre più enorme man mano che il ventre del vulcano emetteva il suo calore. Le pendenze marcate che accoglievano il rovente flusso di lava, d'apprima quasi immobile, poi veloce e diretto verso il fondo della Valle del Bove. I boati, quando non erano soffocati dal vento, riuscivano ad arrivare a Zafferana con garbo, senza troppo disturbare chi anzichè assistere alla caldana del vulcano ha preferito sentire la carezza del piumone.

Il dodici Gennaio è, per certi versi, l'inizio di quella che potremmo chiamare, una serie di particolari eventi. Parossismi su parossismi che in cadenza prima mensile ma successivamente più ravvicinati, svettano la sù, dove il monte tocca il cielo. Protagonista indiscusso è la voragine orientale del cratere di Sud-Est; precedentemente chiamata Pit-Crater (cratere a pozzo) oggi, man mano che gli eventi si sono succeduti, ha acquisito a tutti gli effetti la forma classica di un cono di scorie.

A shallow pit crater (168m) of Giggenbach Volcano had extensive hot water vents. This was the first time we had ever seen boiling water this deep. Dense beds of mussels ringed the crater and we saw a school of curious groupers. Under ambient light, with the submersible lights turned off, the white sulfur deposits shown like a snow covered slop on a full moon night. Streams of thousands of bubbles reflecting light gave the impression of sittin gin a champagne glass.

This is a view into the the throat of a volcanic vent located on the floor of the Halema'uma'u pit crater. Halema'uma'u is located on the south end of the floor of the Kilauea Caldera on the island of Hawai'i. The lava lake in the video is about 400 feet across and 200-300 feet below the floor of Halema'uma'u. The camera is on the Kilauea Caldera floor at the rim of Halema'uma'u and the viewpoint is about 500 feet above the lava. Use headphones or a good sound system and listen for the surges and splashes of lava and also for the sounds of broken glass as parts of the vent's walls fall into the abyss.

www.youfocus.tv - L'Etna ha dato spettacolo. Alle ore 22.48 di mercoledì 12 gennaio si è aperta una profonda depressione nel pit crater e diverse violente esplosioni hanno dato il via ad una colata lavica che si è riversata nella Valle del Bove. Per precauzione dalla mezzanotte è stato chiuso lo spazio aereo circostante l'aeroporto di Catania a causa dell'improvviso incremento delle attività del vulcano.

For much of the day of 12 January 2011, mild Strombolian activity (that is, single, separate bursts of incandescent lava fragments) had been going on at gradually increasing intensity a the pit crater on the east flank of the Southeast Crater cone, at the summit of Mount Etna. At nightfall, I drove up to a place known as Piano del Vescovo, at about 1375 m elevation, which offers a direct view onto the Southeast Crater, and took this video. The activity was quite weak at this time, but certainly gaining strength. A few hours later, it would be an entirely different thing.

The dark spot turned out to be a "skylight," an opening to an underground cavern, that is 35 meters (115 feet) across. Caves often form in volcanic regions like this when lava flows solidify on top, but keep flowing underneath their solid crust. These, now underground, rivers of lava can then drain away leaving the tube they flowed through empty. We can use the shadow cast on the floor of the pit to calculate that it is about 20 meters (65 feet) deep. The origin of the larger hole that this pit is within is still obscure. You can see areas where material on the walls has slid into the pit. How much of the missing material has disappeared via the pit into the underground cavern? hirise.lpl.arizona.edu www.youtube.com BE LOVE - PEACE
