Japan is where the word tsunami originated – because they get more than their fair share. Just over 2 years ago the Tōhoku tsunami killed more than 15,000 people and triggered a nuclear disaster. You could be forgiven for thinking that is as bad as it can get – but the reality is much worse tsunamis can and will occur. A new report suggests that a 9.0 earthquake in the Nankai Trench, off the coast of Japan, could kill 300,000+ people and cause damage in the billions. It could also displace 10 million people, or 8% of the population. Many of those people would be away from home for months or years, and cause a significant strain on the economy…
Major quakes in the Nankai Trench happen every 100-150 years, and thankfully the last one (1330 deaths) was as recent as 1946, meaning Japan isn’t overdue for another, and has time …
Considering all the attention paid to Dec 21, 2012, it is almost ironic the lack of natural disasters. There hasn’t been a major earthquake in many weeks, and looks like the solar cycle has had an early and very weak peak.
Or, is now the time to start fearing the worst?
Tsunami warning after 7.5 quake strikes off Alaska
CHANCE OF FLARES: Sunspot AR1640 has developed a ‘beta-gamma-delta’ magnetic field that harbors energy for X-class solar flares.
The biggest tsunami threats to the USA are on the West Coast. But that doesn’t mean the East Coast is immune. And to make things worse, because they aren’t expecting a tsunami, they won’t be prepared when one arrives.
To be fair, most of the threats are negligible:
Puerto Rico Trench – it is a subduction zone, but it is the Caribbean that is at risk, not the USA
Azores-Gibraltar Transform Fault, off the coast of Portugal – it destroyed Lisbon in 1755, but the USA wasn’t affected
Cumbre Vieja (Canary Islands) – a 2001 study suggested this series of events could send a 70-foot (21 m) wave crashing into the East Coast, but other studies since have decided it would only reach a height of a couple of feet
The biggest risk is from a submarine landslide near the U.S. coast. The resultant tsunami would dissipate quite quickly, so the landslide would need to …
Normally there are just two types of survivalists – those who get off their butt and prepare, and those that might talk about it, but never really get anything done.
If only someone could make it easier for them…
The U.S. city of Cannon Beach, Oregon will suffer a tsunami one day, and nobody knows when. While many people will have a go bag and safe spot worked out, most people will be less proactive. They’ll trust the authorities to hold their hand when the tsunami arrives, will panic when they realize they are on their own, and will quite likely not survive.
Fortunately the local government has decided to make things easier for them. On an allocated plot of high-ground land they will place several shipping containers. For a small fee you get to store a drum, barrel or bucket within the containers. It might be a cheap and dirty survival plan, but it …
And it was only 2000 years ago!
In dispute is the cause, with possibilities including a landslide, an asteroid or a volcano. The evidence comes from sediment in the Hudson River:
“Our models suggest the tsunamis were up to 20 meters (66 feet) high when they entered the Hudson River,” said researcher Dallas Abbott, a geologist at Columbia University’s Lamont-Doherty Earth Observatory in New York.
New York City lies at the mouth of the Hudson. When the scientists drilled out tubes of sediment from the New York and New Jersey area, they discovered layers of unusual debris that, they suggest, were laid down by tsunamis.
“We have layers up to maybe 30 centimeters (11.8 inches) thick,” Abbott said. “They get thinner upriver, where they’re more like 6 centimeters (2.3 inches) thick.”
The 2010 Mentawai Island tsunami in Indonesia provides some useful information for 2012ers who live near the coast. Nine Australian surfers survived the tsunami with just minor injuries. The first step was to recognize that an earthquake could mean a tsunami. The surfers immediately climbed aboard their vessel, “and then he felt a stronger quake. And then they headed to deeper water.”
They would have been completely OK if they had not anchored alongside another boat, which caused a collision when the tsunami hit, and a resulting fire…
So, if you are already out at sea and you reckon there has been an earthquake or tsunami – head for deeper water and ride it out.
I’ve only really investigated the tsunamis of places I recommend to be for maximum safety. For everywhere else, I suggest being at least one hour’s drive inland and 500m above sea level. That is for protection from tsunamis generated by the sea impact of an asteroid or comet.
Of course tsunamis happen all the time, usually due to earthquakes and landslides. A reader pointed out to me that Great Britain has had tsunamis in the past, and people there are not immune. I wonder how many Brits know that they are on an island due to a tsunami?
What had been a cold, dry tundra on the north-western edge of Europe grew warmer and wetter as the ice caps melted. The Irish Sea, North Sea and the Channel were all dry land, albeit land slowly being submerged as sea levels rose.
But it wasn’t until 6,100BC that Britain broke free of mainland Europe …
A particular section of the fault near the Semidi Islands has not ruptured since at least 1788, and measurements on this area – which lies four to five kilometres under water – reveal the pressure is accumulating rapidly. If the Pacific Ocean plate slips, as happened in the geographically-similar Tohoku subduction zone off the coast of Japan, a tsunami could occur – and the deaths could happen as far away as Hawaii and California.
According to Discovery.com, scientists are now investigating the underwater fault-line in the hope of estimating the likelihood of danger to the U.S. and to the Hawaiian islands.
The last time a slip between the Alaskan plates occurred led to the Good Friday Earthquake, on March 27, 1964, which was the powerful earthquake in U.S. history – a 9.2 magnitude earthquake which led to 145 deaths.
Tsunamis also occurred in this area in 1947 and 1957, while a magnitude 7.4 …
In 2003 the Japan government’s expert panel on tsunamis predicted the maximum height of any tsunami created by an earthquake to be 20 meters. In wake of last year’s disaster they have changed their evaluation, and the new worst-case scenario is a 35-meter wave. Tokyo could be hit by 20-meter+ waves, and the Hamaoka nuclear plant could face 21-meter waves – which means they should look into extending the height of their 18-meter high breakwater currently under construction.
The panel noted that the projection was for “the worst possible tsunami” and the “chance of its occurrence is extremely low”.
In my opinion, it went something like this:
A few authors suggest a global cataclysm could occur in 2012
Patrick Geryl says a good way of surviving would be unsinkable yachts
Roland Emmerich makes the movie 2012, using many of Geryl’s ideas. He replaces yachts with massive steel arks
Hardened Structures starts making steel arks for clients
One of those real arks is pictured above. For $20 million you get a 900 ton steel ship that can hold 180 people and has supplies that will last for five years. this isn’t someone’s daydream, this is a genuine survival ark that (hopefully) will be used if a massive tsunami strikes where it is situated.

Speaking of Xmas wish lists…
Here’s an interesting idea – it’s a regular RV that you can leave parked in your driveway. But if a tsunami comes, and the floating tubes are attached, in becomes a boat. It’s tough (kevlar) and self-contained.
Made in Taiwan. Their website is blueeyenoah.com
Check out these features:
diesel generator, plus optional solar panel and wind-power generator
optional positive pressure air filter and water filter
bullet-proof – built with Kevlar
water-proof – it’s a boat when you add the floating tubes
17, 19, 21 and 23 feet models
It’s quite affordable, with prices starting at US$40,000. Available in the USA in the northern spring, just in time for the end of the world.
The name is interesting, here’s what they say:
…a natural disaster about 8,000 years ago wiped out other Homo sapiens races in the Black Sea area, and only one blue-eyed person (family) survived, resulting in a gene explosion by their …
Thailand is now 1/3 under water due to the worsening floods. This map shows the affected area (might take a little while to load).
Up to 20 million tons of debris from the Japanese tsunami in March will eventually be washed ashore on the west coast of the USA, and will start arriving in three years. The debris includes TVs, fridges and shipping boats. Expect beachcombing to become a boom hobby!
Half of the USA got to see the northern lights last Monday, thanks to a coronal mass ejection (CME) from the Sun. The pic below is from Norway, more recent pics are at SpaceWeather.com

…a tsunami escape capsule that could protect up to six people for as little as $1,000….The idea is simple: a 7-foot diameter ball, probably made out of aluminum, outfitted with internal seats and safety harnesses. In general it would have to protect people only for an hour or two, until tsunami waters receded.
This isn’t a bad idea, but personally my preference would be to not live on the coast, or just make sure you are alerted by tsunami warnings and flee inland. So while I certainly wouldn’t rely on one of these, I think they would be well suited to being your plan B for if normal escape is hindered.
Over the years I’ve had a similar idea percolating, but because I am not an engineer it won’t become reality (unless this post inspires someone). I think if you made a capsule but gave it …
The best solution may be the one used routinely to treat water at the Savannah River Site. The process combines activated carbon, reverse osmosis, and ion exchange. If one doesn’t get the iodine-131, two others have a chance to capture the radiation through other means.
And that may be the best solution for the average drinker of tap water as well.
Easy! But if you are thinking that running your drinking water through activated carbon, reverse osmosis, and an ion exchange isn’t easy, perhaps consider moving away from nuclear threats.
The 37 meter tsunami isn’t historical, nor specifically predicted for the future. It was this year’s Japanese tsunami. Deduced from high-water marks.
That’s tall enough to engulf a 10-story building. But “we think we will see [evidence of] bigger waves in other areas,” says Satoko Oki, a seismologist at the University of Tokyo’s Earthquake Research Institute.
The Japanese are #1 experts on tsunamis, and they …
I’m one of the interviewees for an Australian documentary, 100 Days of Disaster, screening tomorrow (Monday) on Channel 10 at 10pm. Patrick Geryl was also interviewed, plus I believe a few orthodox scientists, some religion experts and I think an astrologer. All being asked if we should expect the rise in natural disasters to continue.
To promote the show I am doing 11 (!) radio interviews during Monday – here are the times.
