	EQ Swarm at Mount Hood Volcano, Oregon
		A second focus for volcano-monitoring improvements is Mount Rainier because many communities downstream from the ice-covered volcano are at risk from future lahars (volcanic mudflows).
		Based on the geologic record, moderate-sized lahars caused by eruptions have average recurrence intervals of between 100 and 500 years; large lahars caused by massive landslides have recurrence intervals of between 500 and 1,000 years.
		The expanded seismic monitoring of Alaska's volcanoes and AVO's recently improved remote-sensing capability have increased the ability of scientists to respond quickly and effectively to eruptions of remote volcanoes that pose a threat to aircraft and remote habitations.

		This was the case at Mount St. Helens prior to 1980, El Chicho?n (Mexico) prior to 1982, and Mount Pinatubo prior to 1991, where devastating eruptions were preceded by reposes of 123 years, 600 years, and 500 years, respectively, and many residents were unaware of the hazards before their "mountain" began to rumble.
		Mount St. Helens GPS Network [54] Guided by the precepts outlined in section 3, the USGS Cascades Volcano Observatory established a 40- station GPS network at Mount St. Helens during summer 2000 (Figure 5).
		At Mount St. Helens, there is a continuing need for additional CGPS stations and continuously recording strain meters and tiltmeters, the latter preferably installed in boreholes where near-surface noise sources would be greatly attenuated.

	Mayan Majix - Articles - More Than Just Mount Spurr Ready to Rumble
		The summit dome complex of Mount Spurr is largely covered in ice; its last known eruption was approximately 5,000 years ago.
		Primary hazards from future eruptions at Mount Spurr and Crater Peak include far-traveled ash clouds, ash fall, pyroclastic flows, and lahars or mudflows that could impact drainages primarily on the south and east sides of the volcano.
		Mount Veniaminof volcano is a young stratovolcano with an ice-filled 10-km (6 mi) diameter summit caldera located on the Alaska Peninsula, 775 km (480 mi) southwest of Anchorage and 35 km (22 mi) north of Perryville.

	Volcanoes: An Amazing and Destructive Force
		Primarily, volcanoes are mountains –but unlike regular mountains, volcanoes are not formed by the folding and crumpling of the Earth’s crust, or uplift and erosion.
		Mount St. Helens is the most famous (and active) of the volcanoes in the Cascade Range, due primarily to the well-documented eruption in 1980.
		Mount St. Helens is making news again in 2004, as it lets off steam and ash with the entire world watching.

		Toward the end of 2002, focus was on the eruptions of Mount Etna in Italy, Pago Volcano in Papua New Guinea and Reventador Volcano in Ecuador.
		This ASTER image of Mount Belinda Volcano located on Montagu Island (South Sandwich Islands) was acquired on Dec. 7, 2003.
		Mount Belinda on Montagu Island in the South Sandwich Islands had no record of Holocene or historical eruptive activity until the detections by MODIS.

	Use of SAR Data to Study ActiveVolcanoes in Alaska
		Synthetic Aperture Radar (SAR) data of the Westdahl, Veniaminof, and Novarupta volcanoes in the Aleutian Arc of Alaska were analysed to investigate recent surface volcanic processes.
		At Westdahl Volcano, we examined modifications of the land resulting from the 1978 and the 1991 -92 eruptions.
		Westdahl Volcano is located on Unimak Island approximately 1000 km southwest of Anchorage, Alaska.

		The 11 x 18 km Fisher caldera on western Unimak Island NE of Westdahl volcano is one of the largest calderas in the Aleutian arc.
		The caldera, which is elongated in a NE direction, formed around 9400 years ago, accompanied by emission of large-volume, mobile pyroclastic flows that reached the Bering Sea and the Pacific Ocean.
		Low-temperature fumaroles are located at the western flank of Mount Finch, and Turquoise Lake, at the base of the cone, emits hydrogen sulfide gas.

		New networks were installed at Mount Wrangell (one three-component station and three single-component stations,) in 2000-2001 and at Veniaminof Volcano (nine single-component stations) in 2001.
		The seismic stations in the Veniaminof network were not recorded in 2001 because the telemetry network had not been completed before the end of the report period, thus was not considered to be seismically monitored.
		Hypocenters on Fisher Caldera, Isanotski Peaks, Shishaldin Volcano, and Westdahl Peak that fall within the cylindrical regions centered on Shishaldin Volcano and Westdahl Peak and are located with the Cold Bay velocity model.

		Westdahl volcano is a large basaltic shield volcano on the western end of Unimak Island Alaska in the Aleutian Island Arc.
		The volcano is frequently active with known eruptions from Westdahl Peak in 1964, 1978, and 1991-92 that produced large basaltic lava flows.
		The challenge for this and similar studies is the lack of dense station coverage in the mountainous terrain surrounding Mount Spurr.

		Westdahl has erupted huge gusts of smoke and ash higher than 35,000 feet in the past, and accurate forecasts are a high priority for the Federal Aviation Administration.
		Using InSAR images, Lu estimates that Westdahl's summit has already bulged upward by nearly eight inches over the past eight years, and deformed an 18- mile area of the summit.
		In the West Coast's Cascade range, whose long chain of ancient volcanoes extends from Lassen Peak and Shasta in California to Mount Garibaldi in British Columbia, scientists are focusing on the Three Sisters in central Oregon.

		Over the past year, formal monitoring of Okmok, Tanaga and Gareloi were announced following an extended period of monitoring to determine the background seismicity at each volcanic center.
		The seismicity at Mount Peulik was still being studied at the end of 2004 and has yet to be added to the list of monitored volcanoes in the AVO weekly update.
		Instrumentation and data acquisition highlights in 2004 were the installation of subnetworks on Mount Peulik and Korovin Volcano and the installation of broadband stations to augment the Katmai and Spurr subnetworks.
