Odds increasing for another large quake off the coast of Japan?

We believe we may be on the verge of seeing another degree of intensity in the Japanese aftershocks occurring off the east coast of Honshu, Japan. The depth of the quakes and tremors is increasing which could indicate more subduction pressures along the Pacific plate and may suggest the likelihood of a tension snap-effect could be building. From 9:56 to 13:14 hours, the average depth of seven quakes was 29 km, but from 13:14 to 23.00 hours, the average depth of the last seven quakes is now 58 km- the depth of rattling has nearly doubled. Tension is still also recoiled on the Eurasian plate, particularily around China and the Philippines. Stay tuned…

    What does that mean when the depth has doubled? Mean the tension between the 2 plates is quite large and could mean a large slip = bigger quake?

    Thanks

    • I think you got the idea. It could mean the dynamics are coming into play again for another possible mega-thrust quake. These are the most powerful types of quakes and they occur when one plate becomes obstructed under the other and the tension builds until the plate is violently jerked or thrusted forward in a rupture.

  3. Depends on the type of quake but eventually there is a ripple effect with seismic waves which can perturb magmatic cavitities some distance away.

    There was a 4.7 quake in the mountains of chile in Tarapaca region on the 19th in the morning hours, 3 near puerto rico and a 4.5 off the west coast of el salvador.

    Hi Alvin…what’s the difference between quakes, aftershocks & tremors?

    Thanx!

    • Hi Maiden P. An aftershock is a quake of lesser magnitude, usually one of a series, following a large earthquake in the same area- a foreshock is a smaller magnitude quake that comes before an earthquake. A tremor is a movement of the earth and an earthquake is a series of tremors of significant magnitude.

    Is this not considered ‘normal’ aftershock activity?

    • Denise, I’m afraid I disagree with many traditional theories in geology. Consigning everything to the ‘aftershock’ concept being one of them. Why does an earthquake happen to begin with? A fault ruptures to alleviate stress? Free Dictionary.com defines an earthquake as: “A sudden movement of the earth’s crust caused by the release of stress accumulated along geologic faults or by volcanic activity.” Dictionary.com says an earthquake is: “A series of vibrations induced in the earth’s crust by the abrupt rupture and rebound of rocks in which elastic strain has been slowly accumulating.”

      If the earthquake alleviates stress, why do aftershocks happen? And why do they keep happening up to a year after the quake? If the tire on your car has a blow-out, can it have a second blow-out and a third? I believe we have to look at other causes for occurrences. This region may be at an increased risk of greater instability but people can be lulled into a false security by believing its normal activity. And one example of that is the Mount Vesuvius eruption in 79 A.D., Tremors were reported around the summit for up to 2 years before the eruption but the people in Pompeii grew accustomed to them. Four days before the eruption, the writer Pliny the Younger even wrote about the tremors saying that they “were not particularly alarming because they are frequent in Campania.”

    Thanks for your comments. Here in NZ we have many questions about quakes and aftershocks that I feel haven’t been answered by scientists. They tell us we are experiencing normal aftershock activity from both the September and February quakes in Christchurch. But how can they consider this normal aftershock activity. What similar event can they compare this to? We are also told the February quake is an aftershock from the September quake.

    • Well, many scientists are stuck in the mole of traditonal views, uniformtarianism and see things as occurring in predictable cycles—- when the Earth is dynamic, can be violent and very unpredictable. People dismissed the idea of Noah’s flood as pure fantasy and said 40 days of rain could not cause such a global deluge until Colombia, Pakistan and Australia (2010-2011) were all buried by only a few days of rainfall. As easily as the Earth creates; she can also destroy—–it’s the arrogance of this doomed generation to think they are immune that will be their eventual undoing.

    Also hot springs have appeared in an area since the February quake that didn’t have them previously. This area is considered a dormant volcano. We are told the appearance of these hot springs is not connected to volcanic activity.

    It is my own personal belief that aftershocks are actually more fault lines being formed around the area of the original quake. Scientists have said that in Auckland there was a fault line there they did not know about. With all the 6.0M quakes still happening in Japan I hate to think what is happening there. I hope for the sake of the Japanese people that the Pacific Plate is not now trying to subduct under the Philippine plate. If the recent quake moved Japan to the degree it did, would not all sorts of things be happening around the edges of the Pacific plate? I am 100km north of Sydney Australia and really worry about a 9.0M megathrust quake happening in the middle of the Pacific Ocean. I think we are high enough and far enough away but most people think I have a very vivid imagination. Enjoy your site Alvin. Gen.

    Sorry, in my earlier statement I meant Christchurch not Auckland. Hope that is not an omen.

    Food for thought – within the timeframe of one hour before to one hour after the Japan quake – unfortunately I was in the middle of cooking and did not look at the clock – 8 Indian Ringneck parrots on our back deck began flying frantically in their cages and chirping madly. I couldnt see anything that would have caused the commotion. Sunny afternoon no wind. We also have close to a hundred Indian Ringnecks in our aviaries behind the house and they also were carrying on a treat. I dont know if they were flying around like the others.

    I live a Wyee, New South Wales, Australia Latitude 33.1684S Longitude 151.4753.

    The epicenter of the Japan quake was Lat. 38.322N Long. 142.369. Very close to a mirror image of each other.

    I recently read an article on the net mentioning something goes longitudinally but I dont remember what I was reading or what exactly it was about. I have only been reading about earthquakes, volcanoes and tectonic plates expanding my knowledge.

    Like I said food for thought.

    Did anyone else notice on USGS
    24 March no quakes south of the equator
    25 March 2 south – 1 NZ and 1 Indonesia
    26 March 5 south all Fiji
    27 March 2 south 1 Fiji and 1 Peru
    28 March 3 south 1 Tonga and 2 Chile
    30 March 1 south in Fiji up until 13.2o.10

    Before the Japan quake were there some signals we missed?

    On 11 March before the Japan quake there were 16 M2.5+ quakes in Hawaii region. I think that was at the time the fissures began opening and the lava started flowing. We all expected maybe an eruption but was it telling us that the Pacific Plate was “pulling” over the Hawaiian hotspot because something else was happening. Numerous quakes had already happened off Honshu. Looking back at the data the whole of the 11 March pre M9.0 was virtually Honshu and Hawaii.

    Also on 10 March M4.7 Mid Atlantic Ridge and first up on 11 March a M5.3 Southern East Pacific Rise.

    Alvin, re the reference I made to “something going longitudinally”. It was an article on P-wave shadow zones saying “polarization of P-wave being longitudinal”. I don’t quite comprehend that as I understood that P-waves travel through the earth to the opposite place on the earth.

    Can you enlighten me and others on the following. It looks to me like the P-shadow zone of Greece/Turkey area appears to be somewhere between the South East Pacific Rise and Tonga but further north; that of the Mid Indian Ridge region somewhere near the South East Pacific Rise; and that of the Arkansas region also appears to be in the Indian Ocean.

    Are these relevant to each other so far as all the quakes in Arkansas, Greece area and volatility of Tonga area are concerned. Also the Baja California Mexico and Chile quakes.

    Thanks Gen.
