What does an earthquake of a given size feel like, and how much damage does it cause? How do we express the size of an earthquake? (Two ways) • We must
What would it look like through the window if an earthquake hit now Introduce your pupils to what an earthquake might be like – then take them to a
Higher earth- quake stress drops, coupled with lower attenuation of shaking with distance, result in stronger overall shaking over a wider area and thus more
Warning systems can mitigate the damage caused by tsunamis and other natural events, and prevent the loss of human life and properties
Plan how you will communicate with family members 2 DURING: SURVIVE As soon as you feel the shaking, • DROP down onto your hands and knees so
2 Life After a Big Quake These earthquakes will disrupt services like (see Step 5) Store a fire extinguisher where you can easily get to it
using the the U S Geological Survey's “Did You Feel It?” website Scientists evaluate these Student Copy- Mapping Earthquake Intensity 2 of 5 2
After reading this guide, keep it in a handy spot, such as in your emergency kit Page 6 2 What to expect during an earthquake Small or
Plan how you will communicate with family members 2 DURING: SURVIVE As soon as you feel the shaking, • DROP down onto your hands and knees so
This lesson is about earthquakes and whether human activities can trigger That can change the balance between the two sides of a fault line and cause 10 times larger 30 times larger 10,000 5 100 times larger 900 times larger The Richter Scale does not tell you what each magnitude of earthquake would feel like
Those occurring before the big one are called Foreshocks can be zero or even negative An increase Strong 6 – 6 9 120 Moderate 5 – 5 9 800 Light 4 – 4 9 6,200 (estimated) Minor IITK-BMTPC Earthquake Tip 3 What are Magnitude and Intensity? page 2 of a certain magnitude, different locations experience
Warning systems can mitigate the damage caused by tsunamis and other natural events information and disseminating it in a timely manner are community- based organizations (CBOs) trained in disaster management (see KN 2-1)—
Even if you do not feel shaking, leave coastal areas immediately and evacuate to a 2 3 4 5 6 7 8 9 Data and information flow of earthquakes and tsunamis
Earthquake Hazard and Emergency Management 5-2 Readings: Required student See table below that describes the Modified Mercalli Intensity scale seismometer mass relative to the earth, but it can be mathematically converted to
II, Weak, Felt only by a few persons at rest, especially on upper floors of buildings III, Weak, Felt Many people do not recognize it as an earthquake i e a magnitude 5 earthquake is ten times as intense as a magnitude 4 earthquake Observers feel a strong shaking or rocking of the whole building, room or furniture
How a destroyed city can redesign and rebuild itself is often in part a function of how history of high earthquake frequency, Agadir will one day experience more moderate to Beitreage zur Regionalen Geologie der Erde 22(Part 2): 5- 12
So an earthquake has just one magnitude but the intensity will differ from location to To see this, consider an earthquake that measures 5 on the Richter scale
