4/29/2012 — 5.9M earthquake off the coast of Honshu Japan — 50 miles from Tokyo

Full website post with the links and statistics.. plus links you can use to monitor earthquakes globally: The past 24 hours .. we saw a 6.7M in the southwest Pacific (Tonga) north of New Zealand…. and now a 5.9M in Japan. Be aware of this ongoing rollercoaster of large earthquake swarms. We see them occur in clusters.. so be aware we may be seeing another uptick in seismic activity. Website post here with the statistics and the links you can use to monitor earthquakes globally : Always have your earthquake plans, (and severe weather plans) ready to go… make sure yourself, and your loved ones / friends / or coworkers know the plan and can enact it at a moments notice.

Full website post with all the stats and screenshot proof.. plus links you can use to monitor earthquake — stay current on these developments — also to see if they ever add this one back to the list ! 4.0 magnitude earthquake in SW Wyoming is rather sizable for the area .. surprised they deleted this one quite frankly… even for the USGS .. this one will get noticed by even the skeptics as a “WTH” moment.

Can a Tsunami Strike the Atlantic Coast?

by Zoriah

Can a Tsunami Strike the Atlantic Coast?

Can a tsunami strike the coast of New Jersey, North Carolina, or Florida? The question crossed my mind as I was doing research for my action/adventure novel TSUNAMI, even though the book is set in the Pacific.

The answer is yes, a tsunami hitting the Atlantic Coast is possible, but much less likely than one striking Alaska, Hawaii, or the Pacific Northwest. When it comes to the kinds of natural events that start tsunamis — undersea earthquakes, submarine landslides, and volcano eruptions — the Atlantic is a much tamer ocean than the Pacific. The Pacific basin is encircled by the notorious Ring of Fire with its hundreds of active volcanoes and dozens of dangerous, earthquake-prone subduction zones. The Atlantic has far fewer geological areas capable of posing a genuine tsunami threat. But there are some, and they should be taken seriously.

The one most talked about is the Cumbre Vieja volcano in the Canary Islands, 3000 miles from Boston and 3700 miles from Miami. In 1949, a flank of the volcano split off, creating a 3-ft. rift, the flank sliding down 3 feet toward the ocean before it stabilized. Earthquakes and a buildup of pressure inside the volcano were associated with the event. The concern is that another earthquake or eruption could dislodge the entire flank and send as much as 300 cubic miles of debris plunging into the ocean. One school of thought suggests that such a monster landslide would start a tsunami capable of reaching the eastern seaboard of the United States 5 or 6 hours later.

Even if such an event were to happen, many geologists dispute the notion that it would send a killer tsunami smashing into the East Coast of the U.S. The height of the initial wave would be enormous, but the length between waves would be relatively short, meaning its ability to maintain its energy while travelling long distances would be minimized. Undersea earthquake-generated tsunamis typically have long wavelengths, or distance between waves in the train, and can travel long distances without significant loss of energy. In contrast, landslide-initiated tsunamis tend to have short wavelengths and are usually confined to local areas where they can be highly destructive. In 1883, the Krakatau eruption dumped millions of tons of debris into the ocean and started a 135-ft. tsunami that did incredible damage to Sumatra and neighboring islands but did not affect other areas.

To sum it up, there are two points of view. One maintains the collapse of a chunk of Cumbre Vieja into the ocean could endanger the Atlantic Coast of the U.S. with a major tsunami, while the other view holds that the dynamics of wave formation make such a result unlikely.

The only true subduction zone close to the East Coast is the Puerto Rico Trench, which runs for 1000 miles from Puerto Rico eastward past the Lesser Antilles and out into the Atlantic Ocean. The deepest point in the Atlantic at 28,200 feet lies in The Puerto Rico Trench. Along this trench, the Caribbean tectonic plate is subducting, or sliding under, the North American Plate. This is not as large or active a subduction zone as most of those in the Pacific, but undersea earthquakes have occurred there, resulting in tsunamis that affected the islands in the Caribbean. The last tsunami in the area happened in 1918 when 32 people died in Puerto Rico and the Virgin Islands.

Mt. Pelee on Martinique is one of several active volcanoes in the Lesser Antilles arc. The 1902 eruption of Mt. Pelee is one of the largest on record. It is possible that volcanic debris from future eruptions could crash into the ocean and start a localized tsunami.

Submarine landslides at the edge of the continental shelf along the Atlantic Seaboard might also start tsunamis that could impact coastal cities. In 1929, a 7.2 magnitude earthquake off Newfoundland started an undersea landslide down the continental shelf. The resulting tsunami swept ashore and killed 8 people.

The Atlantic Tsunami Warning System was installed in 2006, comprising five Deep Ocean Assessment and Reporting of Tsunami (acronym DART) buoy stations. Single stations are located off Charleston, Miami, and New Orleans. Two are positioned off Puerto Rico near the Puerto Rico Trench. All provide real time detection of undersea disturbances capable of starting tsunamis that could impact the Atlantic, Caribbean, and Gulf Coasts. Plans call for the addition of at least two more DART stations.

If you live in a low-lying area on the Atlantic Coast, be aware that a tsunami is always a possibility, and be prepared to evacuate on a moment’s notice as directed by local authorities.

Tips for a Surfing Vacation on the Gold Coast of Costa Rica

Tips for a Surfing Vacation on the Gold Coast of Costa Rica

Surfers from all over the world love the convenience of a surfing trip to Costa Rica.  Read on to find out how to surf diverse breaks all within one hour of the international airport in Liberia, with direct flights to major cities in North America.

For beginners, the recommended spot is to go directly to Tamarindo.  Tamarindo is a sheltered beach hidden behind Isla Capitan, and thus receives less swell than most other beaches in the area.  Waves break on the beach at a size perfect for beginners.  There are many surf shops with tons of instructors and boards to rent, so stop in a get yourself a lesson.  You’ll practice standing up on a large and stable board with soft foam cover.

For more advanced surfers, I recommend you stay at Playa Grande.  The beach break in front of Las Tortugas is one of the most consistent in the country.  There are maybe 30 unsurfable days a year at Playa Grande.  The main peak throws lefts and rights and occassionally barrels.  There are also smaller peaks to the left and right including the rock, Pochotes, and further down, Casitas.

You might also like to try out Playa Langosta, on the southern end of Tamarindo.  You drive through Tamarindo following the signs to the Barcelo Hotel.  The break here is heavy and with a moving peak, so not ideal for novices.  It can be surfed on a mid tide, which is nice when most other beaches are best before and after high tide.

Avellanas is another great location. The rivermouth consistently breaks left and right.  Be careful if surfing on a low tide as there is a submerged rock.  Little Hawaii is the most famous break at Avellanas.  It breaks on the reef west of the Hacienda Pinilla beach club.  For an easier swim, walk well south before swimming out and you won’t have to duck dive nearly as much.  Little Hawaii is mostly a right that can get double overhead with a large swell.  Going left will drop you in a rock area, so generally not recommended.

Playa Negra is a great beach for advanced surfers.  There is a large barreling left when the swell is good.  Be careful as there are rocks on both sides of the main break.  Watch the locals to get an idea of how to surf this break.

You might consider surfing Little Hawaii on a mid tide and then making your way to Playa Negra for the rest of the day if the tide is working your way.

The great part of this area of Costa Rica is that it is slow close to the airport and has consistent swell throughout the year.  Search Playa Grande Surf Report on google to get an idea of how the waves are breaking.

Visitors love the fact that the water is so warm too!  You never need a wetsuit, only occassionaly needing a rash guard.

If a tsunami hit the east coast of Canada could it travel down the St Lawrence and become far worse ?

Question by Bobby Dee: If a tsunami hit the east coast of Canada could it travel down the St Lawrence and become far worse ?
I know that tsunamis don’t normally hit Canada, I’m doing some quick research for a short sci-fi story I want to write. Mainly I want to know how badly Quebec City and Montreal would be if the tsunami got funneled down the St Lawrence. A tsunami of roughly 200 feet high by the time it hits the shore.

Best answer:

Answer by linlyons
probably not.
certainly not Montreal — it’s too far up the river.
there is a funnel before Quebec, which would tend to amplify such.

maybe you should look at tides.
they will have the same effect.
most certainly i would not want to be sitting anywhere near the narrow end of the Bay of Fundy.
