What does a Seismograph do?Fill in the blank:A seismograph detects and records________ _______ created by earthquakes and other volcanic activity. It can detect movement that can not be felt. Helping to predict volcanic eruptions. (2 words)

ABGICHFDEQRSTJKPONMLVXWYZUSPACEENTERSEISMIC WA - - -Rocks that were shot out of the volcano are falling all around you. Most are still glowing hot. These projected rocks are called: a) Missilesb) Grenadesc) Bombsd) Pyroclastic DebrisWhat is Going On?!Island Map

Bye-bye Usher Forestand You!

Your Duties.The assignment is strictly research. Scientists believe that there is no risk of eruption.

You are required to:Take rock samples fromthe Aboutoo Rock Mine,Take Daily Seismograph readings Keep a log of all findings from you observations ofMt. Margaritavillefrom hikes and observations from the Usher Forest observation deckCHECKMAP

Question #1Mt. Margaritaville is most likely considered:

ActiveDormantExtinct

Question #2What type of Volcano is Mt. Margaritaville?CompositeCinderConeShieldLavaDome

You are obviously a Knowledgeable Volcanologist!butYou are also bored, young, unsupervised and in a tropical paradise

Thats Metamorphic.You are finding Igneous rocks and crystals. Go Back

What Youre Actually DoingYou do often visit Aboutoo Rock Mine but instead of taking rock samples you are collecting igneous rocks and crystals for you girlfriend back home.

Which three igneous rocks or crystals might you find?

QuartzGraniteMarbleGarnet

ObsidianWhat Youre Actually DoingInstead of reading the seismograph you have turned it into a stereo.

It is not like you need one anywayright?What does a Seismograph do?Fill in the blank:A seismograph detects and records________ _______ created by earthquakes and other volcanic activity.

Rocks are falling all around you!The ground is shaking violently!You know what this meansMt. Margaritaville is Erupting!!!

Uh ohYou make it out of the Mine right before it collapses. You head straight for the research station to make sure that you are correct in your analysis. CHECKMAPBut your seismograph only plays music so it can not help you.

Is it Safe? The rumbling has quieted. Perhaps it was just a fluke earthquake. Mt. Margaritaville is showing no visible signs of eruption.You decide to head to the Usher Forest observation tower to radio back to the mainland and watch more closely.

Usher Forest Observation Tower

The View from the tower Cannot Be Beat!!!But the News you get over the radio is not as good.They can not get anyone to the Island for 3 daysSo you pray that Mt. Margaritaville stays quiet.

Usher Forest Observation TowerJust then you see somethingSomething you did not want to see

What is Going On?!The fast moving giant cloud of hot gas and rock coming at you is called: a) Volcanic Ashb) Pyroclastic Flowc) Andesitic Flowd) Debris AvalancheWhat Are You Going to Do?!The pyroclastic flow is heading right for you. However you have determined that it is a basal flow and will stay close to the ground. You are already high up in the Usher Forest observation tower. But the Maiden Hills of Iron might be close enough to get to if you leave now. What do you do?

Head for the Maiden Hillsof IronStay at the Usher ForestObservationTowerCHECKMAPOopsMaybe you need a little reminder of Volcano types.ReminderGo Back

An Active Volcano is currently erupting. Go Back

A Dormant Volcano is one that is not erupting but will erupt again. Go Back
