When I was a child we lived for a short in Oregon don't remember where but we would go to craters of the moon thats what my mom called it old volcanoes filled with water it was stunning. Question are these volcanoes that they say are dead able to become active again???
Yes they are very able to erupt. I place my forecasting about 80% earthquakes and 20% volcanoes.
It was about 7-8 months ago the USGS reclassified the Long Valley Super Volcano from dormant to Active. There is an estimated 1000 square miles of magma in the magm chamber.
Because I spend majority of my time with Indonesia and South America volcanoes I'm weak to recall the names of Volcanoes but Colli Albania outside of Rome was dormant and came to life, Sinabung in northern Sumatra, a possible eruption in the Congo and another Sumatran volcano called Seulawah Agam that are waking up. I wish I could recall the names but within the last 6 months 2 "Extinct volcanoes erupted. The difference in classifying dormant and extinct. Dormant is in nearly every case a volcano that scientists believe is sleeping a" Probably" won't erupt. Extinct is what scientists believe will never erupt and usually they classify its activity during the Mesozoic Era which I strongly disagree with.
Our halls of higher learning (University's) are teaching false information about both earthquakes and Volcanoes.
Scientist say strongly (USGS) that earthquakes do not have paths they follow, that earthquakes are random.
Using the states as an example...
Over a decade of "Observation" earthquakes follow a path beginning on the Juan D Fuca fault. There are lines that earthquakes follow (consistently following a path (s)) from the Juan D Fuca fault East to Washington state, Idaho, Montana then down to New Mexico, Colorado and accross to Oklahoma heading east across several states and then north through more states and on to Maine.
If you look at a map of the Craton, then plot the time an earthquake hits and where, you will find a distinct path..... Every time earthquake energy hits the states. But the USGS refuses to acknowledge this FACT.
If scientists (USGS) told you one thing and over a decade you observed something completely different happening 100 % of the time, it would be fair to say that they are wrong.
Scientists (USGS) state "Through extended studies" almost every single earthquake strikes at fault lines. Again I observe less than 10% strike at faults, over 90% strike at weak points in the earth's crust, thinner points or where man has drilled for oil&gas or GeoThermal power causing perforations in the crust (weak points)
I again observed by taking the coordinates of an earthquake that the USGS includes when they report an earthquake. Then I would (Still do) cut and paste the coordinates into Google Earth and look to see what's next to the earthquake. Drilling for oil and gas or Geo Thermo, they drill thousands of feet, several miles and not only vertical but Horizontal. If you took a brick and drilled holes with a tiny drill bit every quarter of an inch, the "Perforations" would cause weak points. Mother nature (Earthquake energy) seeks out weak points. What do I see when I look around the earthquake on Google Earth? Volcanoes, volcanic fields, volcanic deformations in the earth's crust like laccoliths which are bulges in the earth's crust where magna pushed up but didn't break through and they have volcanoes circling the outer edge or volcanoes within a mile or two or volcanic fields very nearby. Often I see these laccoliths that have collapsed forming a giant crator and they can be several miles across in size. When you look at a Volcano, it's where mother nature (magma) had sought out a weak point in the earth's crust and punched it's way through it hundreds or thousands of years ago.
The earth is an engine with unthinkable massive explosions deep within the earth as a result magma is under tremendous pressure that seeks out weak points in the earth's crust. An extinct volcano is evidence of a weak point in the earth's crust just waiting for an explosion and if the energy is directed towards the extinct volcano. An active volcano is even weaker than extinct Volcanoes because they don't have the hardened cap to push through, the reason a nearby extinct volcano near an active one remains silent but given a strong enough explosion from deep inside the earth will cause the extinct volcano to wake up...... If that makes sense.
Over the last decade their have been dozens of both dormant and extinct volcanoes erupt.
Long answer, but I wanted both you and the other readers to better understand in depth the how's, why's, where's also.
Good question
