These formations became exposed when the ocean floor was raised by a major volcanic activity in the Devonian forming much of the east coast of Australia.

These outcroppings are the result of volcanic activity.

These " sister and brother " volcanic mountains are approximately from Mount Rainier, the highest of Cascade volcanoes.

These volcanic rocks are the youngest in the canyon.

These peaks are formed of volcanic rock and covered with loose surface rubble.

These mantle-derived magmas ( which are basaltic in composition ) can continue to rise, ultimately to the Earth's surface, resulting in a volcanic eruption.

These rest on older volcanic rocks 15-25 million years old with some older granites and fossil-bearing sedimentary rocks from around 100 million years ago.

These effects are believed to be small in comparison to GHG forcing in the long term, but large volcanic eruptions, for example, are known to exert a temporary cooling effect.

These sequences of fluid volcanic rock cover about of the Interior Plateau and have a volume of about, forming a large volcanic plateau constructed atop of the Interior Plateau.

These volcanic islands, known as the Insular Islands by geoscientists, were formed on a pre-existing tectonic plate called the Insular Plate by subduction of the former Farallon Plate to the west during the early Paleozoic era.

These games were originally scheduled to be held in Rome, but were re-located due to volcanic eruption.

These tubes probably were the magma feeding tubes for volcanic flow that would have once overlain the existing rock, but have since been eroded.

These sulfur and halogen gases and metals are removed from the atmosphere by processes of chemical reaction, dry and wet deposition, and by adsorption onto the surface of volcanic ash.

These techniques date metamorphic, igneous and volcanic rocks.

These consist of a large Carboniferous mountain eroded just before the Permian era with gneiss, granites, porphyritic masses or other volcanic intrusions.

These also include the large lake, the Laacher See, a volcanic caldera formed 12000 years ago.

These calderas and associated volcanic structures lie within the Jemez Volcanic Field.

These volcanic islands are located 646 kilometres ( Suva to Ahau ) north of Fiji.

These dark-halo craters are cinder cone-shaped and are believed by some to be volcanic in origin, although others think they were caused by impacts that excavated darker mare material from underneath the lighter lunar regolith.

These paths show a variety of volcanic activity such as conic depressions, lava tubes and fields, as well as a spatter cone at the northern end of Spatter Cone Loop Trail.

These were once volcanic islands, much like Mauritius and Réunion, which have now sunk or eroded to below sea level or, in the case of the Cargados Carajos, to low coral islands.

These mountains, which are at the extreme southeast end of the East Hesse Highlands ( Osthessisches Bergland ), are partly a result of ancient volcanic activity.

These Kuppen are the remnants of former volcanos or volcanic activity.

These massive stars produce supernova explosions, resulting in expanding remnants that interact powerfully with the surrounding gas.

These explosions later attributed to two barrels of gunpowder that had been placed in the small room under Darnley's sleeping quarters.

These experiments concerned the physics of thermonuclear weapons design and to the effects of high altitude nuclear explosions conceivably to be used for ballistic missile defense.

: These contradictions lead to explosions, cataclysms, crises, in which [...] momentaneous suspension of labour and annihilation of a great portion of capital [...] violently lead it back to the point where it is enabled go on fully employing its productive powers without committing suicide.

These are operated by the Air Force Space Command, and they detect missile or spacecraft launches and nuclear explosions using sensors that detect the infrared emissions from these intense sources of heat.

These explosions occurred in 1970 and 1971, after the Mandrel series and before Grommet.

These harsh critiques were especially fierce once accidental explosions occurred at some plants.

These explosions were made by ' detonators ', a form of large percussion cap placed on the track and activated by the wheels of trains.

These high altitude nuclear explosions can generate an electromagnetic pulse ( EMP ), and charged particles resulting from the blast can cross hemispheres to create an auroral display.

These peaceful nuclear explosions were used to evaluate whether nuclear explosions could be used for non-military purposes such as digging canals and artificial harbors, or to stimulate oil and gas fields.

These explosions would go on to form three new active craters.

These explosions of steam, water, gases and ash reached altitudes of up to 5 kilometers where winds again carried the material across the Arenal reservoir ( Lake Arenal ) and over the town of Tilarán.

These structures were subsequently destroyed by either collapse or steam explosions ( see phreatic eruption ).

These mines, ( together with others which were unfinished ), were filled with around of explosives, the resulting explosions ripped the heart out of the hill over a period of some 10 seconds.

These did not smoulder after the cannon had fired, which had been the cause of constant accidental explosions in the artillery.

These changes remove some, but not all, of the supernova problem, and strengthen the idea of convection being an important factor in supernova explosions.

These may be driven by bursts of star formation activity, resulting in supernovae explosions.

These explosions are generally more extreme than those during normal basaltic eruptions.

These supernovae, the explosions of massive stars, are a type of standard candle ; this means that the processes governing their intrinsic brightness are well understood so that a measure of apparent brightness when seen from Earth can be used to derive accurate distance measures for them ( the apparent brightness decreasing in proportion to the square of the distance-see luminosity distance ).

These Strombolian eruptions generated convective ash columns that reached heights of 200 – 1000 meters, and these explosions lasted for a period of 79 days.

These phreatic explosions generated ballistic volcanic bombs that fell near the summit craters and fine volcanic ash that fell up to 25 km away.

These have occurred before about four-fifths of the explosions at Galeras, and the number of tornillo events recorded before an eruption is also correlated with the size of the ensuing eruption.

These Batarangs come with a range of auxiliary functions, such as producing electric shocks or explosions.
