When and where do we have volcanoes in the United States?Geology
Most of these are located in Alaska, where eruptions occur virtually every year. Others are located throughout the west and in Hawaii (see our Volcano Activity Map for their locations). Kilauea volcano in Hawaii is one of the most active volcanoes on Earth. It has been erupting almost continuously since 1983.”
Where are the volcanoes located in the US?

Are there any volcanoes in NY?
No. The geologic forces that generated volcanoes in the eastern United States millions of years ago no longer exist. Through plate tectonics, the eastern U.S. has been isolated from the global tectonic features (tectonic plate boundaries and hot spots in the mantle), that cause volcanic activity.

Geologists estimate that the trap rock ridges in Connecticut formed from volcanic eruptions more than 170 million years ago.
Are there volcanoes in Pennsylvania?
Today, Pennsylvania has no volcanoes.

No. There are no volcanoes in Tennessee.
Was Appalachian Mountains a volcano?
The Appalachians, a heavily forested mountain range stretching more than 1500 kilometers from Georgia to Maine, were not always so tranquil. In fact, about 460 million years ago during the Ordovician period, they were the site of one of the most violent volcanic events in Earth’s history.
Are there volcanoes in Virginia?
Virginia has two extinct volcanoes, Mole Hill and Trimble Knob. What are the odds of us Virginians dying in a pyroclastic flow? Rest assured that Virginia’s two best-known volcanoes — Mole Hill in Rockingham County and Trimble Knob in Highland County — are in no danger of blowing their tops.
Is Mole Hill an active volcano?
Mole Hill is one of the youngest volcanoes in the Eastern United States, and is probably the last active volcano on the Eastern seaboard. It was last active 47 million years ago. It is one of two volcanoes in the Commonwealth of Virginia.
Are there any volcanoes in WV?
Mole Hill wasn’t the only volcanic activity in the area: Trimble Knob in Highland County and Ugly Mountain in West Virginia’s Pendleton County are also fragments of ancient volcanoes. Volcanic rock has also been found near dairy farms and inside caves in neighboring areas.

Can diamonds be found in West Virginia?
Diamonds don’t exist naturally in West Virginia, yet one of the largest ever found was discovered accidentally in a horseshoe pit in Monroe County in 1928. Geologists are still at a loss to explain how it got there, though speculation has never died down.
Where is the closest volcano to WV?
The closest to Virginia is the Valles Caldera near Santa Fe, New Mexico, about 1,200 miles away. It is closer to the southwestern tip of Virginia than the Saba volcano in the Netherlands West Indies, east of Puerto Rico and the Durango volcanic field on the eastern edge of the Sierra Madre Occidental in Mexico.
What type of volcano is Mole Hill?
About 48 million years ago, Mole Hill was an erupting cinder cone that added a bit of basalt to the limestone landscape. After millions of years of erosion chipping away at the feature, what remains is the cone-shaped magma conduit that served as the volcano’s plumbing.
Are there any extinct volcanoes in the US?
Capulin Volcano National Monument’s namesake erupted between 56,000 and 62,000 years ago and is now considered extinct. The eruption spewed fire, ash, and lava across the land and materials left behind from eruptions piled up to form the conical mountain as it stands today.
What is the most active volcano in the US?
1: Kilauea volcano, Hawaii. Threat Score: 263. Aviation Threat: 48. This active volcano is continuously erupting and was given the highest threat score by the US Geological Survey.
Are there any extinct volcanoes in North Carolina?
There are no known active volcanoes in North Carolina today despite some geologic instability on the coast. References: Fred Beyer, North Carolina, the Years before Man: A Geologic History (1991).
