  Mount Pavlof - Wikipedia, the free encyclopedia
Steam and volcanic gas rising from the summit crater of Pavlof Volcano
Pavlof Volcano is a stratovolcano of the Aleutian Range on the Alaska Peninsula.
The mountain shares a name with the nearby Pavlof Sister, which last erupted in 1786.

Syneruptive caldera collapse at Mount Katmai, 10 km east of the eruption site, and displacements elsewhere in the magmatic plumbing system generated 14 earthquakes in the magnitude range Ms 6 to 7 (extraordinarily energetic for volcanic seismicity) and as many as 100 greater than Ms 5.
The caldera-forming or climactic eruption of Mount Mazama drastically changed the landscape all around the volcano and spread a blanket of volcanic ash at least as far away as southern Canada.
Lahars at Mount Rainier can be classed in 3 groups according to their genesis: (1) flank collapse of hydrothermally altered, water-saturated rock; (2) eruption-related release of water and loose debris; and (3) hydrologic release of water and debris (Scott et al., 1985).

 SEASON OF FIRE   (Site not responding. Last check: 2007-10-31)
Still, Pavlof is one of the most-studied volcanoes in the world because its restless rumblings offer a good laboratory to help geologists understand how to predict when other volcanoes are likely to kill.
In 1902 Mount Pelee poured superheated gas and volcanic ash onto the city of St. Pierre on Martinique, burying the town and killing nearly 30,000 people in a matter of minutes.
Mount St. Helens blew its top on May 18, 1980; Mount Pinatubo belched an enormous ash cloud over the Philippines on June 15, 1991; and Krakatau in Indonesia erupted on August 26, 1883, triggering tsunamis that killed more than 36,000 people.

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.

The volcano is 7km in diameter and has two active vents, one located on the northern side and the other on the eastern side (Miller et al, 1998) and the overall outline of the volcano appears cone shaped.
The type of eruptions normally seen from Pavlof consist of Strombolian and Vulcanian eruptions where the main components are bombs and ash that normally reach heights of around 200 to 300m (Miller et al, 1998).
The largest eruption in Pavlof's history occurred in 1911 when a fissure opened expelling large lava flows, together with these flows large blocks were expelled from the volcano.

 Global Volcanism Program | Emmons Lake | Summary
The massive Emmons Lake stratovolcano, located north of Volcano Bay and SW of Pavlof volcano, is truncated by one of the largest calderas of the Aleutian arc.
Mount Emmons, Mount Hague, and Double Crater are post-caldera cones of dominantly basaltic composition that were constructed along the SW-NE trend of the elongated caldera, which is up to 1150 m deep.
A large fumarolic area is located on the south side of Mount Hague, and the only reported historical activity from Emmons Lake volcano was the emission of steam plumes from Hague in 1990 and 1991.

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.

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.

 Frequently Asked Questions About Volcanoes and Volcanologists
For example, USGS scientists who studied Mount St. Helens during the 1970's recognized that, for thousands of years, it had been the most active and explosive volcano in the entire Cascade Range.
The risk of mudflows formed this way is especially high along rivers downstream from Mount Rainier, because of the large population on floodplains, the huge weakened edifice of the volcano, and a long history of large flows that occurred when the volcano was otherwise dormant.
During the huge eruption of Mount Pinatubo in the Philippines in 1991, dozens of light to moderate earthquakes (magnitude 3 to 5) were felt by several hundred thousand people.

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.

Between 1994 and 1999, the AVO seismic monitoring program underwent significant changes with networks added at new volcanoes during each summer from 1995 through 1999.
The existing network at Katmai –Valley of Ten Thousand Smokes (VTTS) was repaired in 1995, and new networks were installed at Makushin (1996), Akutan (1996), Pavlof (1996), Katmai - south (1996), Aniakchak (1997), Shishaldin (1997), Katmai - north (1998), Westdahl, (1998), Great Sitkin (1999) and Kanaga (1999).
These networks added to AVO's existing seismograph networks in the Cook Inlet area and increased the number of AVO seismograph stations from 46 sites and 57 components in 1994 to 121 sites and 155 components in 1999.
