Is Galeras on a plate boundary?
Galeras Volcano: Plate Tectonic Setting
The Galeras volcanic complex is located in the Colombian segment of the South American Andes mountains.
The Andes in Colombia are the result of a collision between the Panamanian tectonic block with South America, which detached part of the South America plate from the continent
.
Is the Galeras volcano dormant?
Galeras is one of Colombia's most active volcanoes
, with at least 20 eruptions since the 1500s. Approximately 400,000 people live within the volcano's zone of influence. This image was acquired by the Landsat 5 satellite's Thematic Mapper (TM) instrument on August 7, 1989.
What causes Galeras to erupt?
Galeras had become active in 1988 after 10 years of dormancy. In 1993, the volcano erupted
when several volcanologists were inside the crater taking measurements
. The scientists had been visiting Pasto for a conference related to the volcano's designation as a Decade Volcano.

What is the tectonic setting of Mount Fuji?
Geological Setting
Fuji (or Fujisan) is a classical stratovolcano, but its plate tectonic setting is quite complicated.
It lies on the Eurasian tectonic plate, with the Philippines Sea Plate subducting to the south, and the Pacific Plate subducting to the north
.
Can scientists predict a volcanic eruption?
Volcanologists can predict eruptions
—if they have a thorough understanding of a volcano's eruptive history, if they can install the proper instrumentation on a volcano well in advance of an eruption, and if they can continuously monitor and adequately interpret data coming from that equipment.
What type of volcanic eruption occurs at Kilauea in Hawaii?
Kilauea is a basaltic shield volcano, erupting
a type of basalt known as tholeiite
. This type of lava is the dominant extrusive during the shield building (the main stage) of hawaiian volcanism and is the dominant basalt type erupted on Earth.

There were no immediate precursors in the hours before the eruption.
The seismic signal associated with the eruption lasted for 15 minutes, and saturated one nearby station for 2 minutes
(Crater 2). The 16 July eruption lasted 10 minutes and saturated the same station for 1 minute.
What was significant about the 1963 eruption of Surtsey off the coast of Iceland?
Surtsey is a new island formed by volcanic eruptions in 1963-67. It has been legally protected from its birth and
provides the world with a pristine natural laboratory
. Free from human interference, Surtsey has produced long-term information on the colonisation process of new land by plant and animal life.
How old is the Galeras volcano?
Galeras volcano is located in southern Colombia close to the border with Ecuador. The volcanic complex consists of several small calderas, cinder cones and a stratovolcano. Two caldera forming events have occurred at the volcano.
