I guess I don't have to worry about it........but then there was a fissure flow volcano about 10 miles away from me at one time from where I am in Southern New England.

When they say something about changing how we think about how continents behave I tend to doubt it as they don't say anything but that.

I'd very much like to know what they mean by this......they don't have any details here.

Mean by what?...Some details are in the write-up...

...

The 5th paragraph down.......I tried to copy it but it came up with numbers.

I didn't really see many details except for it taking millions of years. I do agree that in 50 million years there will likely be a volcanic arc along the east coast of North America as there was 180 million years ago.

Do some research if there isn't enough details for your liking...Post your findings here...

I've been studying and researching the geology of New England for 40 years.....I was wondering what details they had.

As I said before......it wouldn't surprise me and I live near a former fissure flow volcanic vent.

Europe's tallest volcano Mt. Etna erupts.
Mount Etna volcano roars into action with ash and lava
ROME (AP) — Mount Etna in Sicily has roared back into spectacular volcanic action, sending up plumes of ash and spewing lava.

Italy’s National Institute of Geophysics and Vulcanology (INGV) says that the volcano, which initially “re-awoke” in late July, sprang into fuller action Thursday evening by shooting up chunks of flaming lava as high as 150 meters (500 feet) almost constantly.

On Friday, INGV said the action was continuing, feeding ash plumes several hundred meters (yards) into the air above the crater.

No evacuations of towns on Etna’s slopes were reported.

Sicilians farm on the fertile soils of the slopes of Etna. The volcano is also a popular destination for hikers on the Mediterranean island.

I guess the ski season might be delayed this year.
Unless they can come up with lavaboarding.

Manam volcano in Papua New Guinea erupted.
Unusually strong eruption at Manam volcano sends an ash column 15 km (50,000 feet) above sea level and forces 2,000 people to flee in PNG
An island volcano on the north coast of Papua New Guinea erupted early on Saturday, forcing 2,000 villagers to flee from lava flows. The eruption began at 6 a.m. local time (2000 GMT Friday), sending an ash column 15 km (50,000 feet) above sea level. The ash falls were so heavy that trees broke under the weight. The RVO’s Steve Saunders said it was an unusually large eruption.

Threat of Yellowstone Volcano Eruption Increases to 'High,' Says USGS
October 25, 2018 Updated: October 25, 2018
The U.S. Geological Survey said that it is classifying 18 volcanoes in the United States as having a “very high threat,” and it classified the Yellowstone volcano in Wyoming as “high.”

The USGS updated its volcano threat assessments list for the first time since 2006.

It said that “11 of the 18 volcanoes are located in Washington, Oregon, or California, where explosive and often snow- and ice-covered edifices can project hazards long distances to densely populated and highly developed areas.”

The danger list is topped by Kilauea in Hawaii, which has been erupting continuously in 2018.

Mount St. Helens as well as Mount Rainier in Washington, Alaska’s Redoubt Volcano, and California’s Mount Shasta are also the top five, the USGS said.

Alaska’s Mount Okmok, Akutan Island, and Mount Spurr also saw higher threat scores than in 2006, the USGS said.

The USGS has threat assessment levels of very low, low, moderate, high, and very high.

“Five of the 18 very high threat volcanoes are in Alaska near important population centers, economic infrastructure, or below busy air traffic corridors. The remaining two very high threat volcanoes are on the Island of Hawaii, where densely populated and highly developed areas now exist on the flanks of highly active volcanoes,” the agency said.

It added: “The high- and moderate-threat categories are dominated by Alaskan volcanoes. In these categories, the generally more active and more explosive volcanoes in Alaska can have a substantial effect on national and international aviation, and large eruptions from any of the moderate- to very-high-threat volcanoes could cause regional or national-scale disasters”

Threat scores rose for Oregon’s Newberry Volcano as well as Wyoming’s Yellowstone. The Yellowstone caldera is listed as “high” by the USGS.

There are 161 active volcanoes in the U.S.
