'Never ever in my lifetime'! Rotorua resident left stunned by first eruption he's ever seen on lake  

Another hydrothermal eruption in Rotorua is likely a "secondary event" of earlier activity, a volcanologist says.

GeoNet on Wednesday afternoon reported the hydrothermal eruption in Rotorua.

"We've had reports of another hydrothermal eruption at Rotorua. Our trusty volcanologist @Eruptn is heading out to take a look," the geological hazard monitoring agency said on Twitter.

Eyewitness Shane Aromoana said the rumble could be heard before the eruption could be seen.

"It was just black sand going up in the air.

"It was awesome."

GNS Science volcanologist Brad Scott said the eruption was "small to very small."

"If I came here without the knowledge [it happened] I wouldn't see any evidence of it."

He said the eruption was about two metres high.

"It's what geothermal systems do. Eruptions like this are not uncommon.

"The unusual thing is it hadn't happened before."

In regards to a possible earthquake linkage, Scott isn't sure.

"How do you join those dots? I wouldn't discount it though."

There's also a lot of activity in Kuirau park at present, he said.

Mud volcano erupts in Azerbaijan

Mud volcanoes in Azerbaijan become more active

14.03.2011 17:09

 

The Dashgil and Ayrantoken mud volcanoes in the Azerbaijani settlement of Alat in the Gobustan region have become more active, due to aftershocks,the Ecology and Natural Resources Ministry told Trend.

Geology Institute Mud Volcanoes Department Director Adilyev stated, "The institute is researching Shikhzeyirli and other mud volcanoes,"  He added that tremors were systematically recorded in the area .  Source: http://en.trend.az/news/society/1844925.html

The ministry is closely studying the Shikhzeyirli mud volcano eruptions that began on March 13 in the Gobustan region, the ministry said.

During their studies, the ministry has recorded large clefts on the volcano's 

surface as a result of the explosion.

During the eruption, the flame reached 60-70 meters.

Residential homes are located approximately 600-700 meters from the volcano.

At present, gas is being discharged in various places on the volcano. The volcano last erupted in 2005. However, this eruption was accompanied by a much louder explosion.

The Shikhzeyirli mud volcano outside the Shikhzeyirli village in the Gobustan region erupted on March 13. A large mud-bath occurred on the surrounding area as a result of the explosion.

Underground Volcano Near Cape Hatteras, NC?

 

By Wendy Anderson, eHow Contributor

There are no underground volcanoes in Cape Hatteras, North Carolina. 

The New England seaboard is free of igneous volcanic activity. 

However, there may be mud volcanoes in the Cape Hatteras area.

Types of Volcanoes

1. The igneous volcano--what most people think of when they hear the word "volcano"--is a vent in the earth's crust from which magma, ash, and gases explode. The "mud volcano" is different: methane gas forms a slurry of water and mud, and its eruption is generally much less violent and at a much lower temperature than that of an igneous volcano.

Geography

1. The majority of North American igneous volcanoes are located along the Pacific coast, in the Pacific Ring of Fire. The Ring of Fire traces the western edge of the North American tectonic plate. North Carolina is located well away from the edge of this plate, and has no igneous volcanoes.
2. 
   

Speculation

1. Mud volcanoes can develop wherever there there is sediment containing gas hydrates, especially methane. As the eastern coast of North America has many areas of such sediment, it is possible that mud volcanoes may appear in the vicinity of Cape Hatteras.
