Discussion Overview

The discussion revolves around the relationship between recent earthquakes and the tsunami caused by the Indonesian quake, exploring the geological processes involved and potential future seismic activity in the Indian Ocean region.

Discussion Character

  • Debate/contested
  • Technical explanation
  • Exploratory

Main Points Raised

  • Some participants argue that the recent earthquake in Pakistan is not an aftereffect of the tsunami earthquake, as the locations are not geographically close.
  • Others suggest that both events are related through the movement of tectonic plates, specifically the Indian Ocean Plate and its interactions with surrounding plates.
  • One participant notes that the Indian sub-continent is advancing and that this motion leads to the uplift of the Himalayas and associated seismic activity.
  • Concerns are raised about the potential for more earthquakes in the Indian Ocean region, with some suggesting that fault systems may become more or less active over time.
  • Another participant mentions the historical context of seismic activity in mountain regions and predicts that earthquakes will continue for millions of years due to ongoing tectonic pressures.
  • There is a discussion about the risk of tsunamis in countries bordering the Indian and Pacific Oceans, particularly in light of recent seismic events.
  • One participant shares observations of increased volcanic activity in the Ring of Fire and its possible correlation with seismic events in the Indian Ocean.
  • Concerns about property insurance in relation to seismic risk are expressed, with suggestions to consult seismic risk maps for specific areas.

Areas of Agreement / Disagreement

Participants exhibit disagreement regarding the connection between the tsunami earthquake and other seismic events, with some asserting a lack of direct correlation while others propose a broader geological relationship. The discussion remains unresolved on the extent and implications of future seismic activity.

Contextual Notes

Participants mention various geological processes and historical seismic activity without reaching a consensus on the implications for future earthquakes or the specific risks associated with different regions.

Who May Find This Useful

Individuals interested in geology, seismology, disaster preparedness, and the effects of tectonic activity on regional safety may find this discussion relevant.

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.
