Edison Elementary 5801 Main St. Bow WA 98232 January, 17, 2007 The white house 1600 Pennsylvania Avenue NW WA, PC, 20500 Dear Mr. President, Thank you Mr. P. for allowing me to answer your questions, and to show you what I know about earthquakes and where they occur. In these few paragraphs I will answer your questions that you had asked me about. Your first question you had asked me was where most recent earthquakes have been occurring and if it occurs in certain places? Well they do occur in certain places such as Japan, Indonesia, Alaska, Fiji, Tonga, and California. Most earthquakes occur along plate boundaries. It is because plates are constantly moving and when the plates interact with each other they cause an earthquake. Your second question was weather or not there is any way to determine what parts of the world are prone to earthquakes. There are areas that are prone to that kind of stuff. You know the area’s that are prone to earthquakes just by looking at the map because there are so many of them in one area. Like California, and the other ones that I have mentioned. They are mostly on plate boundaries, so they know what to do if there was an earthquake. Your third question was if there was a relationship with earthquakes and volcanoes. I believe that there is, I think that they have at least two things in common. My first reason to believe this is they both destroy things. I mean earthquakes move the earth and they happen because of the earths plates colliding. Volcanoes erupt and they destroy land as well. My second reason is because they both are a part of the earths system are natural forces I guess you could call it. Your fourth and last question was what’s causing the earthquakes; well the earth is made out of plates called plate tectonics. When the plates intersect with each other they cause a vibration and then an earthquake. There are three faults that cause the earthquakes known as the reverse fault also known as convergent and compression, normal faults also known as divergent and tension, and lastly the strike slip also known as the transform fault and shearing. Now they move in directions such as the normal fault the plates move away from each other, strike-slip the plates move diagonally rubbing against each other, and lastly reverse fault where the plates collide. Once more I would like to thank you for allowing me to answer your questions, If you have any questions that involve earthquakes please feel free to contact me. Sincerely, Breanna D Leader of the USGS
