Space Forum / Shuttle / December 2004Orbital sensing?
It occurred to me, after the appalling loss of life two days ago around the Indian Ocean, that if some sort of early warning system could be built, this could to some extent have been avoided, at least for the areas several hours away. Now I know the Pacific has seismic sensors, and pressure wave detectors and these seem to work well, but is there any technology which could detect these waves from space? After all, the area viewed could be vast and help to point at the general areas of potential trouble when earth borne equipment may have been trashed by the event itself.

Such an early warning system exists, but was of little help in this instance because the quake was near the shore, and most of the areas hit were near the quake. D. SignatureTouch-twice life. Eat.

Umm, Derek, you may want to look again at those maps. Somalia for example is pretty far from the quake itself. As are any of the parts India, the Maldives, etc. > D. "Greg D.

At any rate, an early warning system does exist (at least in the Pacific). D. SignatureTouch-twice life. Eat. Drink. Laugh. -Resolved: To be more temperate in my postings. Oct 5th, 2004 JDL >"Greg D.

There was a line on one of the teletext news items here saying that there's no warning system in the Indian Ocean because there aren't many quakes, or words to that effect. It probably didn't help that Somalia is too disorganised to do anything, and Indonesia is too close. I still haven't seen much from Bangladesh. > "Greg D.

Yes, in the Pacific. Unfortunately, this was in the Indian Ocean. And in fact US geologists did pick up the quake and tried to warn the various countries, but with no real infrastructure in place, the warning did no real good. > D. 'Areas several hours away' would practically eliminated every area that were hit the hardest by this event. India, Maldives, and Sri Langka while are quite far away, they are still too close to epicenter. The only ones that might benefit are coastal area at the African continent. It should be noted that there are many coastal communities, and even IF you warn all (or most or some or few) of them, that doesn't necessary mean that they will obey the warnings. |
