we had an earthquake in NJ. When my china cabinet began to sway and shake the glasses inside so loudly, I knew it was an earthquake.What protective actions should we have taken during the earthquake? What have you learned in science about energy in a system that helps you to understand an earthquake? What are the parts of the system that caused my china cabinet to move? What did you do?

Based on the movie "Ashfall", what are the things that we should do before, during, and after a natural calamity such as an earthquake? Identify 3 for each and explain if these are effective ways for us to be safe.

how did the '2008 Sichuan Earthquake' destroy properties & infrastructure?

Aside from earthquake drills, describe what activities your school/community conducts to teach you what to do before, during, and after an earthquake.

Earthquake is one of the most devastating natural calamities which Blank 1 Question 2 (caused, will cause, had caused, causes) sudden shaking of the earth surface. It, not only causes damage to buildings and other structures but alsoBlank 2 Question 2 (affected, will be affected, had affected, affects) the surrounding environment and our lifestyle significantly. An earthquake can trigger many sudden changes in the environment which can Blank 3 Question 2 (would be classified, will classify, is classified, be classified) as primary and secondary. The subsidence and surface faulting Blank 4 Question 2 (is, was, were, are) the primary changes. The secondary effects are the displaced rocks, tsunami, ground cracks, liquefactions, landslides. These effects are known as earthquake environmental effects. The scales which use these effects of an earthquake as a parameter for assessment Blank 5 Question 2 (is known ,were known ,was known, are known) as Earthquake Intensity Scales. These scales Blank 6 Question 2 (quantified, quantification, quantity,quantify)  an earthquake based on the observed effects on the surroundings .The magnitude scales for earthquakes are logarithmic scales. The Richter scaleBlank 7 Question 2 (are based ,were based, had based, is based) on seismograph readings measuring Earth movement. In addition to the Richter scale, scientists also Blank 8 Question 2 (using ,will use, had used,use) a Moment Magnitude that measures the total energy of an earthquake, called the seismic moment. The seismic moment of an earthquake Blank 9 Question 2 (were determined, are determining, had determined, is determined) based on three factors. The first factor is the distance that rock slides along a fault surface after it breaks, called the fault slip. The second factor is the area of the fault surface that Blank 10 Question 2 (are, was, were, is)  actually broken by the earthquake. And the third factor is the measurement of how rigid the rocks are near the broken fault.

How can installing monitoring and warning systems help to reduce the impacts of disaster risks during the 2008 Sichuan Earthquake?
