The Richter scale is a logarithmic scale, meaning that the numbers on the scale measure factors of 10.

Describe how the Mercalli Scale works. jasminenottage15 https://padlet.com/jorja_davies_28/709il6vd4vw9/wish/116676783 The Mercalli Scale measures the effects of an earthquake and is distinct from the moment magnitude which is a measure of the energy released.]]> 2016-07-20 05:08:06 UTC https://padlet.com/jorja_davies_28/709il6vd4vw9/wish/116676783 4 What are the main differences between the 2 scales? jorja_davies_28 https://padlet.com/jorja_davies_28/709il6vd4vw9/wish/116676863 the Mercalli scale measures the intensity of an earth quake the Richter scale describes measures the magnitude by measuring the seismic waves ]]> 2016-07-20 05:09:55 UTC https://padlet.com/jorja_davies_28/709il6vd4vw9/wish/116676863 3. Describe which scale is more commonly used today and why ? jayden_windle https://padlet.com/jorja_davies_28/709il6vd4vw9/wish/116677041 There are a number of ways to measure the magnitude of an earthquake. The first widely-used method, the Richter scale, was developed by Charles F. Richter in 1934. It used a formula based on amplitude of the largest wave recorded on a specific type of seismometer and the distance between the earthquake and the seismometer.]]> 2016-07-20 05:13:12 UTC https://padlet.com/jorja_davies_28/709il6vd4vw9/wish/116677041 7. For areas that are earthquake prone, engineers need to design buildings that are safe and can withstand earthquakes. What are some things that architects and engineers ensure in builds in earthquake areas. jayden_windle https://padlet.com/jorja_davies_28/709il6vd4vw9/wish/116677142 Buildings are basically designed to support a vertical load in order to support the walls, roof and all the stuff inside to keep them standing. Earthquakes present a lateral, or sideways, load to the building structure that is a bit more complicated to account for.]]> 2016-07-20 05:14:52 UTC https://padlet.com/jorja_davies_28/709il6vd4vw9/wish/116677142 6.List some ways that Scientists can predict an earthquake occuring and evaluate the effectiveness of these methods. jorja_davies_28 https://padlet.com/jorja_davies_28/709il6vd4vw9/wish/116677178 Scientists can predict where major earthquakes are likely to occur, however, based on the movement of the plates in the Earth and the location of fault zones. They also can make general guesses about when earthquakes might occur in a certain area, by looking at the history of earthquakes in the region and detecting where pressure is building along fault lines. For example, if a region has experienced four magnitude 7 or larger quakes during the past 200 years, scientists would calculate the probability of another magnitude 7 quake occurring in the next 50 years at 50 percent. But these predictions may not turn out to be reliable because, when strain is released along one part of a fault system, it may actually increase strain on another part]]> 2016-07-20 05:15:22 UTC https://padlet.com/jorja_davies_28/709il6vd4vw9/wish/116677178 5What is the name of a scientist who studies earthquakes? jorja_davies_28 https://padlet.com/jorja_davies_28/709il6vd4vw9/wish/116720311 Seismologist]]> 2016-07-20 23:17:44 UTC https://padlet.com/jorja_davies_28/709il6vd4vw9/wish/116720311  8.Describe the importance of Early warning systems. jorja_davies_28 https://padlet.com/jorja_davies_28/709il6vd4vw9/wish/116720359 Early warning is a major element of disaster risk reduction. Early action can often prevent a hazard turning into a human disaster by preventing loss of life and reducing the economic and material impacts. To be effective and sustainable they must actively involve the communities at risk.]]> 2016-07-20 23:18:57 UTC https://padlet.com/jorja_davies_28/709il6vd4vw9/wish/116720359 9. List some early warning systems, describe how they work and evaluate their effectiveness with the amount of warning they can provide. jayden_windle https://padlet.com/jorja_davies_28/709il6vd4vw9/wish/116720499 Television, internet, radio calls, internet etc. When an earthquake is sensed it immediately sends out a message by what ever source is being used, and because now days nearly everyone has their TV's or phones on its easier for people to find out ]]> 2016-07-20 23:22:10 UTC https://padlet.com/jorja_davies_28/709il6vd4vw9/wish/116720499 jorja_davies_28 https://padlet.com/jorja_davies_28/709il6vd4vw9/wish/116721929 2016-07-20 23:50:33 UTC https://padlet.com/jorja_davies_28/709il6vd4vw9/wish/116721929
