EES 0836
Hawaii Volcano Observatory (HVO)
Disasters: Geology vs. Hollywood
Introduction
Steven Chemtob, PhD, watched a clip from Disaster Zone: Volcano in New York (2006) and addressed the difficulties of forecasting eruptions. Obviously, in the clip Steven watched, tectonically speaking, there would be no way to predict that a volcano would erupt beneath that man’s house. Note, however, that there are events that can precede eruptions that can aid volcanologists in making predictions. In this activity, you will be using the United States Geological Survey’s Hawaiian Volcano Observatory website and making predictions as to future eruptions. Learning Objectives
●
Compare how the depiction of an eruption of a volcano from the movie Disaster Zone: Volcano in New York relates to real-world phenomena. (3, 4, a, b)
●
Outline how the eruption of volcanoes in Hawaii would affect people and the environment. (3, 2, a, c)
●
Assess the possibility of a future eruption through current observations. (1, 3, c)
Part 1: YVO at bird eye view
If you visit Hawaii Volcano Observatory
you can see they observe several volcanoes, including the subaquatic volcano Loihi. Loihi is expected to become the next Hawaiian island in 10,000 to 100,000 years. Using the included website, answer the following questions. 1.
How many volcanoes are monitored at this observatory?
- There are 6 volcanoes monitored at this observatory.
2.
How many volcano(es), if any, are considered:
a.
Very high threat:
- Kilauea and Mauna Loa
b.
High threat: -Hualapai
c.
Moderate threat:
- Haleakala and Manua Kea
3.
Are all of these the same type of volcano? -Yes these are all shield volcanoes
4.
Do any volcanoes have an advisory above green/normal? If so, which volcanoes, what color is the
advisory, and why?
- Kilauea currently has an orange watch advisory, that’s erupting. The current is stable for now at
EES 0836
the summit and rift zones. There have been high levels of volcanic gas which is hazardous.
5.
Are volcanologists predicting it will erupt? -
Kilauea erupted on January 5
th,
2023. Since then all the recent eruptive has been confined to the volcanic crater. The east and central cents are not erupting. The western lake of Kilauea remains active but has very weak lava flows.
Part 2
: HVO with more focus
As you can see in Part 1, HVO is monitoring more than just volcanoes. But we are here to look specifically at Kilauea. Is it leading up to something, or is it just doing what it always does? Either click on the link to Kilauea under threat potential or click here
. 1.
What type of volcano is Kilauea?
-Kilauea is a shield volcano
2.
What is the composition of the lava?
- Kilauea has a Basalt composition
3.
What is the “Threat Potential”?
- The threat level is very high
4.
Look at “Current Alerts”
a.
What is the current Volcano Alert Level: - The alert level is Watch
b.
What is the current Aviation Color Code: - The current aviation color code is orange
5.
Summarize the “Activity Summary”
a.
Is Kilauea erupting?
- Yes but has diminished greatly in the past 24 hours
b.
What is the rate of seismicity?
-The rate of the seismicity and ground deformation is undisclosed however, steady rates of both ground deformation and seismicity continue along both the east rift zone and the southwest rift zone.
c.
What is the rate of ground deformation?
- The rate of the seismicity and ground deformation is undisclosed however, steady rates of both ground deformation and seismicity continue along both the east rift zone and the
