	Soufriere Hills, Montserrat, West Indies (Site not responding. Last check: 2007-10-19)
		The lava dome was visible on the 23rd and scientists recorded several observations of the volcano's small lava dome and pit crater.
		Volcanic and seismic activity remained at low levels and small rockfalls and sporadic pyroclastic flows traveled down the E and N flanks of the lava dome into the Tar River Valley, White's Ghaut, and the top of Tuitt's Ghaut.
		Volcanic activity decreased slightly this week and most activity was focused on the lava dome's center and ENE flank, producing rockfalls and numerous pyroclastic flows.

		Volcanic domes are characterized by magma with high a silica content (70%) and that is extremely viscous (Keller 209).
		The viscosity of the magma affects the steepness of the sides of the dome and the ratio between diameter and height (Williams 190).
		One type of dome is the upheaved plug, which is formed as a steep-sided column from extremely viscous lava and is present in the Panum Plug of the Mono Craters in California (Williams 189).

		The volume of the lava dome measured August 18, 2006, was 85.0 million cubic meters (111 million cubic yards) and was growing at an average rate of less than 1 cubic meter per second (1.3 cubic yards per second).
		Previously we had estimated that the new dome probably surpassed the volume of the 1980-1986 lava dome (77 million cubic meters or 100 million cubic yards) by the end of 2005.
		The high point of the lava dome (the actively growing spine) on June 15 was 2,335 meters (7,660 feet), but it is currently lower than that owing to the recent large rockfalls from the spine.

	USGS Photo Glossary: Lava dome
		Volcanic domes are rounded, steep-sided mounds built by very viscous magma, usually either dacite or rhyolite.
		The longest historical dome-building eruption is still occurring at Santiaguito Dome, which is erupting on the southeast flank of Santa Maria volcano in Guatemala; the dome began erupting in 1922.
		The volcanic dome in the Cascades is Lassen Peak in northern California.

	Lava dome - Wikipedia, the free encyclopedia
		In volcanology, a lava dome is mound-shaped growth resulting from the eruption of high-silica lava (usually rhyolite and/or dacite) from a volcano.
		Domes may reach heights of several hundred metres, and can grow slowly and steadily for months or years.
		Ultimately, many volcanic domes are destroyed by large explosive eruptions.

	Volcanic Dome Hazards
		Most volcanologic remote sensing studies to date have focused on basaltic shields because of ease of access, frequency of eruptions, and relevance to ancillary planetary geologic studies.
		However, many more people have been killed or are at risk from the typical hazards of silicic volcanoes: pyroclastic flows and surges generated by lava dome collapse; silicic fissure eruptions fed by dikes; debris avalanches, lahars, and other mass movements; and catastrophic magma chamber evacuation and caldera collapse.
		The framework for these studies will be a theoretical model, previously developed by the P.I., that relates the velocities and kinetic energies of pyroclastic flows generated by dome collapse to five properties of the dome and its setting: volatile content, temperature, chemical composition, thickness of cooled carapace, eruption rate, and underlying topography.
