       Why tsunami tides were not formed?

Question: Why tsunami tides were not formed in spite of the massive underwater earthquake of 8.6 magnitude in Indonesia on 11 April 2012?

Answer: I think when the tectonic / seismic plates generate a VERTICAL knock, after the earthquake; massive tides will be generated out of the same. If the knock acts in OTHER-THAN-VERTICAL directions, the resultant tsunami tides would be shorter and weaker.


Devastating Tsunami Tides in Japan... Indonesia and other countries
in Indian ocean were spared from this deadly havoc on 11 April 2012 

 
Comparison between Indonesian and Japanese earthquakes / Tsunamis:

  1. April 2012: Indonesian:  8.6-magnitude: Distance 269 miles / 434 kilometers
  2. March 2011: Japanese:  8.9 magnitude: Distance 80 miles / 130 kilometers
In addition to the assumed difference in the direction of the knocks generated at the tectonic plates, there is a difference of 0.3 between the magnitudes of the two earthquakes. The Epicenter location, 434 km, in case of the Indonesian earthquake is 304km farther than that occurred in Japan at a distance of 130 km. As a result of the above a weaker tsunami has occurred in Indonesia in April 2012.
