    Compared to other natural disasters like hurricanes and fires, earthquakes strike without warning anywhere in the world.

    There’s no telling when they’ll happen and most of the time, they bring extensive damage.

    During an earthquake, your own home itself can become a danger to you and your family. How can you prepare your own home for an earthquake?

    Preventing Structural Damage

    The first step in quake-proofing your home is to prevent the damage where it is most likely to occur. Providing structural support to areas that are weak such as the front porch, glass doors, wooden decks, and the garage. Consulting a professional engineer is the best option in order to evaluate the structure of your home and make the necessary improvements in order to strengthen these areas. Making use of the best materials is essential in protecting your home as well. Concrete dries fast and is one of the sturdiest materials that are earthquake-resistant.

    Securing Furniture

    It’s common for furniture to get thrown around when a quake starts, especially if it’s a strong one. The danger of cabinets, light fixtures, and other furniture to fall down and injure you or your family is high when these things are unsecured. What you need to do here is bolting or fastening them safely in place. This ensures that they won’t fall down easily and pose any danger for people inside your home during an earthquake. Use the best available framing hammer to fasten nails on the feet of cabinets and fasten dressers to the walls to prevent them from toppling over and hurting anyone.

    Placing Objects Safely

    Head injury is quite an expected injury during earthquakes. This is because of heavy objects falling on people’s heads during all the shaking and this can even be serious at times. If you don’t want this to happen, be smart in storing objects in your home. To make sure safety is a priority, pack heavier things such as tin cans, bottles, and glass on the lower cabinets and cupboards as they won’t be falling from a great height. Store the lighter objects on the upper bins to prevent potential hazards. In addition, always lock your cupboards since they may jar open during a quake.

    Check Your Electronics

    Power outlets can also be damaged during an earthquake. Knowing how to apply and repair switch wiring can help prevent electrical hazards at home. Due to the intensity of the shaking, some wires and panels can be dislodged or worse, completely broken and exposed. This would then lead to electrical hazard or even a potential for fire, so securing your homes electronics is a priority for earthquake preparedness. Consult an electrician to secure the electrical wires in and around your house, making sure there are no live or exposed wires before a quake. Repositioning outlets that are near potential hazards like the sink or the gas would also make it a lot safer.

    Having a Safe Roof

    A roof made from strong materials can easily survive an earthquake. If a roof does get damaged, not only does it make repairs hard, it also poses a danger of taking the whole house with it. Using lighter materials such as aluminum or metal is a great way to reduce weight on the roof and prevent extensive damage. Applying asphalt shingles is also a good alternative because they’re lighter and more flexible than other roofing materials. If you’ve bought an already-built house, asking a contractor to replace the roof with lightweight materials can be done beforehand.

    Water Heater and Gas Appliances

    Getting clean water after an earthquake can be difficult if some services end up unavailable. Your water heater can easily be damaged during an earthquake if it’s not secured properly. Faster the water heater against the wall, making sure that it stands upright. Replacing the metal pipes with more a flexible material will also prevent damage during the quake. Gas-powered appliances also benefit with more elastic connections and prevent possible gas leaks.

    Additional Earthquake Proofing

    Taking the pre-emptive measures for earthquake-proofing your home is important. A house can become a dangerous place during a quake and ensuring the safety of your family is a must. Securing doors and packing up supplies beforehand will also help save you time when disaster does strike. Knowing what materials to use for your home will decide whether your house can survive or not.

    Conclusion

    We can’t really predict when and where an earthquake might hit.  If you know the right things to do, then setting your home right, you can save a lot of money and time in repairs

    One thing the military does better than anyone is technical training.  In the military they take a raw 17 year old and in the course of a few months teach them highly technical skills that the young soldier or sailor must do under times of great stress.

    This military based training manual on basic electricity is something every farm, homestead, or prepper library should have on the shelf.

    This is an expanded and revised U.S. Navy training course text provides thorough coverage of the basic theory of electricity and its applications. It is unquestionably the best book of its kind for either broad or more limited studies of electrical fundamentals.

    This book is divided into 21 chapters and an extensive section of appendixes. Chapters cover safety, fundamental concepts of electricity, batteries, series direct-current circuits, network analysis of direct-current circuits, electrical conductors and wiring techniques, electromagnetism and magnetic circuits, introduction to alternating-current electricity, inductance, capacitance, inductive and capacitive reactance, fundamental alternating-current circuit theory, direct-current generators, direct current motor magnetic amplifiers, and synchros and servomechanisms. Appendixes acquaint lay readers with common terms, abbreviations, component color-code, full load currents of motors, and cable types; they also supply trig functions, square and square roots, basic formulas, and laws of exponents.

    This book supplies the reader with a complete basic coverage of all important aspects of electricity. And, drawing on its ample funds, the Navy was able to fill this text with dozens of illustrations so that the book becomes almost a multimedia teaching process.

    This is an excellent text for classroom use or for home study. Students will also find it a valuable supplement to courses in which theory is emphasized while little attention is paid to application; it will also supplement a course in which this situation is reversed. In addition, Basic Electricity serves the lay reader who simply wants a knowledge of fundamental concepts of electricity or wishes to study more advanced concepts and applications. 1969 edition.

  • PRN Episode #32 Interview Andrew Morrison

    PRN Episode #32 Interview Andrew Morrison

    We have been doing a lot of podcasts dealing with alternative construction, and today we continue this trend by hosting one of the leaders in the strawbale building community.  The Shepherd School is proud to get to talk to Andrew Morrison of strawbale.com.

    Andrew Morrison has been a strawbale builder for more than a decade and has hands on experience building hundreds of homes using strawbales as the main building material.

    Strawbale is cheap, provides awesome insulation, has great sound-deadening properties, and amazing fire and insect resistant properties – I know that sounds counter-intuitive – but listen to the show and here Andrew Morrison explain why.

    You can learn more by visiting his blog and store at the links below:

    Strawbale Products

    We have also embedded a video below from Andrew Morrison talking about his workshops – it is a very good way to get manpower to build as well as help learning about the process.

    I have long been interested in strawbale construction, I am very excited to talk to Andrew.

    The show is scheduled for Monday at 10pm central time at this link.

    If you cannot listen on Monday, you can always download the podcast for listening at your own leisure.

  • Strength of Materials

    Strength of Materials was developed at MIT, to be a textbook.

    This distinguished introductory text is popular at engineering schools around the world. It also serves as a refresher and reference for professionals.

    In addition to coverage of customary elementary subjects (tension, torsion, bending, etc.), Strength of Materials features advanced material on engineering methods and applications, plus 350 problems and answers. 1949 edition.

    I keep this book to help design projects that I am working on, as well as to teach myself engeneering concepts.  But beside that normal use, I keep it so that people more trained than me may have it available in the event of a large scale disaster.

    I look at reference books like  Strength of Materials the same way I look at surgical supplies stored away.  I am not the one that will use it, but that does not mean that the person using my stored goods won’t use it to help me.

    This is not an easy book to read, but that does not mean that it is not valuable.  But, it is an introductory text, so it is not beyond the abilities of any individual that is willing to take the time to think about what they are reading.
