Unfortunate mind earthquakes are catastrophic events that nobody on the face of the Earth is safe and to which we are exposed at any time. But thanks to the internet and computer access, detect an earthquake in time possible from our home. The Quake-Catcher Network is a project that is currently working the universities of Stanford and California to detect earthquakes in time, making use of the computer, internet and software, developed by the same entities. In the laptops this is made possible thanks to the accelerometers that have the newer laptops and they usually come to protect the hard drive, and on board computers, since it does not have this type of device, this is feasible by means of a sensor connected to a USB cable and which can be obtained at a cost of US$ 49. The software comes to operating systems like Mac and Windows and you can download it free from the official site, where you can also get a manual for the use of this program and also sign up as a volunteer in the project. In loqueNecesita.com you will find the link to sign up and download the software. With respect to this issue you will also find another post, showing a video that will teach you how to make a homemade seismograph with the Wiimote. Original author and source of the article.
