Transcript of Yellowstone Power Point

Yellowstone Power Point
Yellowstone National Park
What types of volcanic eruptions are associated with Yellowstone?
How often are these volcanic eruptions dangerous?
Where are the areas most prone to hazardous eruptions?
How often does a Yellowstone hot spot create a caldera?
At least 5 large calderas have been identified
eruptions of basalt and rhyolite lava flows
3 extemly large explosive eruptions have occured in the past 2 million years
How do we monitor volcanoes
Hydrothermal Activity Data:
In what way is hydrothermal activity dangerous?
water and rock thousands of feet and cretae new landscapes of hills and
In your professional opinion, is there an immediate (next 100 years or so) danger related to hydrothermal activity at Yellowstone?
In my opinion the hydrothermal activity can cause pressure and damage.
the largest hydrothermal-explosion in the world is located on the northern edge of Yellowstone lake
There are more than a dozen large hydrothermal-explosions craters in Norris geyser Basin and Mammoth Hot Springs

Where would hydrothermal activity keep you from building a research station?
Volcanic gases data:
What gases are monitored at Yellowstone?
Sulfurous and visible steam, carbon dioxide, sulfur dioxide, SO2, CO2
In what way are these gases dangerous?
Sulfurous gas produces paricles called aerosols, which can cool the climate by blocking sunlight. Drastically change global climate
Where are the areas that are most dangerous?
In places where these are high levels of rhyolite magma present
In your professional opinion, is there an immediate next 100 years or so) danger related to release of volcanic gases at Yellowstone?
in my opinion their would be danger rel;ated to released gases at Yellowstone because almost every year 2,000 earthquakes occur and release gases.
Earthquake Activity data:
How are earthquakes dangerous?
How many modern day large (greater than magnitude 5) earthquakes have occured at Yellowstone?
What is the most common magnitude of earthquakes recorded at Yellowstone?
Does the pattern of earthquakes at Yellowstone suggest movement of magma?
Earthquakes are dangerous because earthquakes can cause a lot of damage to buildings and streets and cause danger to peoples houses.
2,000 earthquakes occur every year
the most common magnitude of earthquakes recorded at Yellowstone is 7.5.
In what way could ground deformation be dangerous?
many Yellowstone hotspot has been dated but only few have large caldera-forming
it could alter global weather patterns and have enormous effects on human activity, especially agriculture production
What pattern do you observe in the historic data?
Does uplift or subsidence affect some areas more than others? Would this affect where you might put your research station
In your professional opinion is there an immediate danger related to ground deformation at Yellowstone?
in my opinion their is an immediate danger related to ground deformation at Yellowstone because hydrothermal explosion.
Ground Deformation data:
Some caldera complexes erupted more than 15 to 20 occured along the hotspot
Some caldera complexes erupted more than 15 to 20 occured along the hotspot
the most likely type of eruption would not be volcanic but hydrothermal really small but explosive
hydrothermal explosions
lava flows
ash/tephra fall
pyroclastic flows
earthquakes
climate change
