Earthquake

   
            An earthquake is a sudden release of energy in the earth’s crust that creates seismic waves. The seismicity of an area refers to the frequency, type and size of earthquakes experienced over a period of time. In its most general sense, the word earthquake is used to describe any seismic event that generates seismic waves. Earthquakes are caused monthly by rupture of geological faults, but also by other events such as volcanic activity, landslides, mine blasts, and nuclear tests. An earthquake’s point of initial rupture is called its focus or hypocenter. The epicenter is the point at ground level directly above the hypocenter.

      I think that you can discuss through comments. I think that this is the only way that keeps us in touch and exchange ideas.

    I agree with Mari that this is a great video, especially with the earthquake that we just had a few weeks ago. I have lived in Boston for many years and have never felt an earthquake. I thought that earthquakes only happened in California. This is information that everyone needs to know.

    I love the topic! I searched for some earthquake info. on the net after we had the earthquake here in New England. I found a much more basic video that reviews some earthquake vocabulary: http://teachertube.com/viewVideo.php?video_id=83831

    This is a very intersting topic. I have been in a few cities in the past and have felt a earthquake , it was no fun. As an adult , i found the earthquakes to one of the most scariest things to be involved in with no control. I can only a imagine how kids would react.Excellent topic !!! I hope you braved your experience with the earthquake better than I did. I look forward to other information and insight you can share on this or others subjects.

    Karima, your blog is getting more lively with all the additions. I especially like the voki character that you used, I think that it will be very beneficial for ELLs to understand the content. your animoto movie is well done as well and a good reminder of what ELLs need.
