SUMMARY

The discussion clarifies that the recent earthquake in Pakistan is not a direct aftereffect of the 2004 tsunami but is related to the same tectonic activity involving the Indian Ocean Plate and the Eurasian Plate. The Indian subcontinent is advancing at approximately 1.6 inches per year, leading to significant seismic activity along pre-existing fault lines, particularly in the Himalayas. The conversation emphasizes that regions around the Indian and Pacific Oceans, including Indonesia and the Philippines, will continue to experience earthquakes and potential tsunamis due to ongoing tectonic movements.

PREREQUISITES
  • Understanding of tectonic plate movements, specifically the Indian Ocean Plate and the Eurasian Plate.
  • Knowledge of seismic activity and earthquake mechanics, including fault lines and thrust faults.
  • Familiarity with seismic risk assessment and mapping techniques.
  • Awareness of volcanic activity and its relationship with tectonic movements.
NEXT STEPS
  • Research the Indian Ocean Plate's tectonic dynamics and its impact on regional earthquakes.
  • Study seismic risk assessment methodologies and tools for specific geographic areas.
  • Explore the relationship between volcanic activity and tectonic movements, focusing on the Ring of Fire.
  • Investigate recent seismic activity trends in the Himalayas and surrounding regions.
USEFUL FOR

This discussion is beneficial for geologists, seismologists, disaster management professionals, and anyone involved in earthquake preparedness and risk assessment in regions bordering the Indian Ocean.

In a word- no. The two locations are nowhere near each other.

So will we be seeing more earthquakes in the indian ocean plate?
I have to get my houses insured!
 
The Himalaya mountains were formed by upthrust of the Earth's crust as the Arabian, Indian and Australian plates are pushing against the Eurasion plate.

See - http://en.wikipedia.org/wiki/India_Plate

The regions (and adjacent areas) containing mountains: Balkans in SE Europe; Causaus in Turkey, Iran, Georgia, Armenia, Azerbaijan; and Himalayas/Pamirs/TienShan in Afghanistan, Pakistan, India, China, Nepal, Bhutan, Burma, will see earthquakes for many millenia (probably millions of years) to come.

Also, Indonesia and Philippines, will see more earthquakes and perhaps very strong ones. The countries around the Indian and Pacific Oceans are at risk of tsunami.
 
like Astronuc says, yes there will be more. If you meant "will there be more compared to normal", areas of fault systems can become more and less active over time, but over the plate boundary in general, I wouldn't expect there to be more earthquakes than normal.

If you are concerned about insuring properties, you should look into the seismic risk of the specific area. Not all areas of India are at high risk from earthquakes, as the fault zone lies mainly in the north near the himalayas where the Indian plate collides with the Eurasian plate.. Some information and seismic risk maps can be found here: http://asc-india.org/info/seisindia.htm

Besides monitoring earthquakes and seismic activity in my spare time, I also watch on-going and new volcanic activity. This started when an associated photographed a volcano, Asayama, which had abruptly erupted near his home.

Since 2003, there seems to be a slight increase in seismic activity in the Ring-of-Fire on the western side of the Pacific Ocean, and the Sumatran extension.

Interestingly, there are two volcanos in the Andaman Islands - one on Barren Island and the other on Narcondum Island. The current eruption of Barren Island began on 28 May 2005, but it seems to be low level. This is the northern end of the fault zone that ruptured causing the tsunamis of Dec 26, 2004.

There may very well be a surge in volcanic and seismic activity in association with the Indian plate. There is also recent activity of a volcano in Ethiopia.

So, all people in all countries bordering the Indian Ocean should be aware that there are risks of earthquakes, volcanoes and tsunamis - perhaps for a while. Northern Sumatra is still getting earthequakes regularly with mag 5+, particularly along the Sunda trench.
