Letter Re: Earthquake Resistant Residential Architecture

Hello James: Attached is an e-mail I sent to my daughter.  Her boyfriend is from Honduras and she dreams of doing missionary work there.  I thought it may be of interest to some of your readership.  I left out a great deal of information on building site selection (her boyfriend already owns five acres) and foundations.  There seems to be differences in opinion regarding firmly anchored and sand-bed isolation between footings and walls.  Most of my information was gleaned from the book Technical Principles of Building for Safety (Building for Safety Series) by Coburn. Dear X.: I did a little …


Your Earthquake Audit, by M.B.S.

We are survivalists who live on a hobby farm within The American Redoubt. In the 23 years we have lived in this region I have yet to feel the ground shake beneath my feet. That’s welcome news speaking as a former Californian who has been through two “big ones”. Yet, for whatever reason (the Holy Spirit, possibly) I began thinking about earthquakes two months ago. Because of this mind set, when three earthquakes, southeast of us, occurred in Utah around the 13th of February and the next day a magnitude 6.0 quake hit off the coast of Oregon. That got …


Letter Re: Earthquake Retrofit an Old House

Hi Jim, Living in an area that’s earthquake prone and overdue for a large one, I’ve spent a fair amount of time researching ways to limit any damage that we might experience in our home.  In 1994 the Northridge earthquake and the resulting fires were the cause for the creation of a device that, I feel, is instrumental to possibly saving any home with a gas-line.  It’s commonly referred to as a Northridge valve.    Simply, it’s a seismic device that stops the flow of gas at the house meter should there be any seismic event over 5.2 on the …


Earthquake Retrofit an Old House, by Greg E.

2011 was a year of deadly and devastating tornados, and an earthquake that shook the east coast.  One of the largest tornados hit a suburb in my county in the Birmingham Alabama area. We are also only one state over from the New Madrid earthquake zone that starts in the Memphis area.  After taking several closer looks at the foundation and basement of our 50 year old house, I realized we were living with a false sense of security. After researching online, I learned that in certain large events, mainly earthquake, but also from high winds, if the house gets …


Letter Re: Vignette of an Eastern U.S. Earthquake

Hi Mr. Rawles: I want to share with you today’s events in Washington DC. I came home early from school and decided to go to the gym to burn off some of those summer pounds. As I was walking to the gym (two blocks away), listening to my iPod. All of the sudden I heard some crashing and screaming. Since this is DC, everything happens so I kept on walking. I finally realized that something was definitely wrong when I saw people pouring out from every building including a rather overweight man wearing only a bath towel  that was way …


Three Related Disasters (Part 3), by Joe Refugee From Tokyo

After the first few days, it was possible to get some idea of what had happened. The initial numbers of fatalities had been fairly low, and it was hard to know how many had survived in the coastal towns. As the phone systems and many roads there were devastated, a big effort was going to be required just to scope out the damage. Sadly, it became clear that well over 10,000 lives were lost. In terms of life in Tokyo, though, it was electricity and basic supplies useful during disasters that became somewhat hard to come by. The other major …


Fully Ready But Not Fully Prepared, by Expat D. in Japan

Where We Were In Kogoshima, in the southern part of Japan, residents know that when the active Sakurajima volcano finally erupts with its full force, they will most likely be killed. Some of them even know that it will be the quaking and the toxic pyroclastic flows that kill them rather than flowing lava. Similarly, living just 15 miles from the heart of Tokyo, we have always been aware that Tokyo is past due for a major earthquake. When it hits, it will cause suffering on a scale that will make Kobe and Mexico City seem as if they got …


Three Related Disasters (Part 2), by Joe Refugee From Tokyo

Days Two and Three I slept well the night of 11-3-11, which was good, because I hadn’t the two previous nights. A premonition, perhaps? Like the day after September 11th, there was an eerie feeling everywhere. The weather was nice, at least in Tokyo, but a cold front was coming in from the North, so the folks near the Tohoku coast were going to be suffering even more. It was obvious that the damage was off the charts, but the television downplayed the likely deaths, and a big question was whether the government had learned from its poor performance during …


Three Related Disasters (Part 1), by Joe Refugee From Tokyo

Day One Just another day for an American ex-pat in an office in a skyscraper in Tokyo, or so it seemed. There was a nice view in several directions, offering a chance to see a real panorama of the city. In just a few minutes, that view would include large fires and streets packed with cars and people walking. The reason, of course, is it was 11-3-11.   The first inkling of trouble was a minor feeling of movement, and this lasted for perhaps a minute, and then things got worse. The shaking got to where it was time to …


Letter Re: Nuclear Incidents in Japan – The Truth and the Rumors

Hello James, It is with a heavy heart that I watch the nuclear incident unfold in Japan. I am watching my nightmare come true, and I pray for the safety of the people in Japan. As you know, my article that was published in your blog last September was primarily written to alert the public about the possible EMP effects on nuclear power plants. While the initiating event may have been different, the results of the loss of all AC power at the site results in virtually identical consequences. Events are playing out very similarly to those that I had …


Three Letters Re: The Earthquake in Japan and its Aftermath

Dear James,   I just wanted to alert you to the possible impact of what is actually happening at Japan’s Fukushima nuclear power plant.  The grid has gone down, and it appears that the emergency diesel generators have failed.  There is apparently no off-site or on-site AC power.  This is very similar to the scenario that I outlined in my article posted last September in SurvivalBlog (except for the precipitating event for my article described an EMP event).  We have a potential disaster worse than Chernobyl in the making.   In fact, even the mainstream media is now taking note.  Here is …


Lessons From Christchurch: Urban Earthquake Preparedness and Survival by Alex F.

Let’s be honest. Thinking about the end of the world is kind of fun. If it weren’t, there wouldn’t be so many post-apocalyptic novels, movies and television shows. Preparing for a relatively slow-moving Armageddon like a civil war or pandemic demands a lot of shopping which is an enjoyable pastime. However, as the grieving citizens of Christchurch, New Zealand attest, the most likely threats are also the most sudden, the least glamorous, and not fun at all. TEOTWAWKI may or may not happen in our lifetimes, but almost everyone has to deal with a natural disaster at one time or …


Looking For the Wave: Our Experience with Hawaii’s 2010 Tsunami Alert, by An Oregonian

Here on the Oregon coast we have included precautions for a Tsunami in our emergency preparations.  This last spring while on vacation on the north shore of Oahu we experienced some valuable lessons when the Tsunami alert was raised after the earthquake in Chile.  This experience has helped us and hopefully will provide food for thought for others. We have family living on the north shore of Oahu, in Laie that we were staying with during our trip.  About 4am in the morning as I was sleeping on the porch, a woman knocked on the door to inform the family …


Letter Re: Strapping Hot Water Heaters for Earthquakes

Hi James, Regarding River’s advice about strapping a water heater: He is correct about the value of doing this, but I would advise anyone considering this task to do more than just nail a strip of plumbers tape around the water heater. As a 40 year native of Southern California (yes, I am looking to escape) I am better acquainted than I would care to be with earthquakes and what they do. I am also a general contractor. California’s requirements for bracing water heaters can be annoying, but they do exist for good reason. Anyone looking at bracing their water …


Letter Re: Earthquake Hazard, Risk, and Mitigation

James: Thank you for your interesting and informative web site and mission.  Just a few short thoughts on earthquake hazard, risk, and mitigation, since it’s a pet interest of mine for some time and I come at it from a slightly different background than some.  I’m a southeastern US resident in an area about 300 miles give or take from the New Madrid fault zone.  My community is actually located in the second most seismically active area east of the Rockies, so I do have some personal investment in the topic.  Additionally, I have more than 20 years’ experience in …
