Mount Sinabung erupted again on Saturday, just a day after authorities
allowed thousands of villagers who had been evacuated to return to its
slopes, saying volcanic activity was decreasing. Rescuers found 14 bodies
and rescued three people with burn wounds. Two other people have
subsequently died. - Picture: Chaideer Mahyuddin/AFP Telegraph
Sudden eruptions have occurred in Japan, Chile, Costa Rica, Indonesia, and Galapagos (in the
past 1-2 months or less).

A rare M2.7 earthquake struck in North Arizona at the long dormant Uinkaret volcanic field. The last eruption of this volcano occurred nearly 1,000 years ago (1100 A.D.).
Speaking of rare earthquakes at 1,000 year dormant volcanoes, just a few days ago (May 31st), a different earthquake struck in South Utah at the Markagunt Volcanic Plateau (just before the Oregon Earthquake swarm struck off the West coast this week).
The Markagunt volcanic plateau also has been dormant for approximately 1,000 years.
The earthquake swarm off the coast of Oregon is occurring directly on the flanks of a large undersea unnamed dormant volcano , thus these dormant volcanoes showing movement on the West coast are a sign of building stresses below the plate. Read
A noteworthy earthquake swarm developed off the coast of Oregon over the past day.
As it turns out, this swarm of earthquakes is occurring very close to a large undersea volcano off the West coast of the United States.
Multiple large events struck about 250 miles West of the Oregon coast very close to ( 30 miles from ) from the Cleft Segment undersea Volcanoes.
The Cleft Segment volcano(es) are located along the South Juan De Fuca fault zone, just 100 miles South of the currently erupting Axial Seamount Volcano.
The earthquakes started with a 5.8M, and topped out with a magnitude 5.9 (6.0 revised). Clearly this earthquake swarm is happening in close proximity to undersea volcanoes. Could possibly be a new eruption of a different undersea volcano in the area… or the signs of a coming possible eruption at this location.
At the top of the world
A very rare, and most likely volcanic related earthquake has struck near the exact NORTH POLE of the planet. Upon inspection using Google Earth, the earthquake epicenter is located near an undersea volcano which was discovered in 1999.. currently called “UNNAMED” by the USGS. This earthquake is listed on the USGS as “North of Svalbard”. Read Dutchsinse

Active Volcanoes
A volcano will be classified as an active volcano if at the present time it is expected to erupt or is erupting already. One of the best examples of this classification of volcanoes would be Kilauea which has been erupting since 1983. There are a total of close to 1,500 of such volcanoes on the planet.Dormant Volcanoes
The classification of volcanoes which is called dormant would be a volcano that is not erupting or predicted to erupt in the near future. However, it has done so in recordable history. A dormant volcano is also expected to have an eruption sometime in the future. Sometimes the difference between a dormant volcano and an active volcano can be pretty small. That is because even though a volcano can be dormant for hundreds of years it is still expected to have an eruption in the future.A dormant volcano could be very dangerous because people in the surrounding areas are usually not prepared and complacent leaving close to the mountain. Before its eruption in 1980, Mount St. Helens was dormant. Read more on Basic Planet
