I hope this doesn't cause another horrible Tsunami. As if those poor people haven't been through enough.

It's a 7.7 quake say Sky News.

USGS has it as a 7,7. A big one


Magnitude 7.7 - BANDA SEA
2006 January 27 16:58:48 UTC

very deep...

Depth 341.5 km (212.2 miles)

it's a big one, but it seems deep

I still can't figure out or remember which was it, if deeper quakes caused tsunamis or if shallow ones do?

guess it all has to do with location too... so far no word on tsunami warning yet

The shallower the quake, the more damage Usually and the tsunami depends on a horizontal or vertical shift of the plates.

The tsunami quake was shalllow (30Km's) and the plates suffered a long vertical shift which thrust the sea floor upward.

en.wikipedia.org...
The earthquake was unusually large, in geographical extent. An estimated 1200 km (750 mi) of faultline slipped about 15 m (50 ft) along the subduction zone where the India Plate dives under the Burma Plate. The slip did not happen instantaneously but took place in two phases over a period of several minutes. Seismographic and acoustic data indicate that the first phase involved the formation of a rupture about 400 km (250 mi) long and 100 km (60 mi) wide, located 30 km (19 mi) beneath the sea bed - the longest rupture ever known to have been caused by an earthquake. The rupture proceeded at a speed of about 2.8 km/s (1.7 mi/s) or 10,000 km/h (6,300 mph), beginning off the coast of Aceh and proceeding north-westerly over a period of about 100 seconds.

EMSC has it as a 7.7 as well (at least at the moment they do).

Here´s the location of this quake:

Depth 341.5 km (212.2 miles)

Magnitude 7.5

This is in fact a strong one, again affecting the same already affected area.

According to the USGS it has been located 195 km (120 miles) S of Ambon, Moluccas, Indonesia and 440 km (275 miles) NE of DILI, East Timor. Even DARWIN (Northern Territory of Australia is at 825 km (520 miles) from the quake.

Though there is no Tsunami warning yet, this event can provoke a Tsunami.
Let´s wait and see.

As well as, keep a close eye on the other part of the planet... Sometimes, when a strong one affects one part of the Earth, the other part shakes too, not long after.

In relation with the 7.7 eathquake
Located in BANDA SEA.

NOAA

The evalution based on the magnitude and historic tsunami information was not sufficient to generate a tsunami damaging CALIFORNIA, OREGON, WASHINGTON, BRITISH COLUMBIA OR ALASKA.
Some of these areas may experience a small sea level increase.

The Pacific tsunami warning center will issue tsunami bulletins for Hawaii and other areas of the Pacific.
---- End of summary of the bulletin.

We´ll wait for the Indonesia area...

PACIFIC Tsunami Center

According to the previous mentioned Source, there is no tsunami threat in the Pacific or elsewhere based on historical earthquake and tsunami data.


I am not sure if we should feel relieved...
What was the probability for another strong quake taking place close to the same spot as the strong earthquake that took place in Indonesia, that caused a strong tsunami so soon after it?

IS this showing us the possibility of another one taking place there on the same location?

The Fault in Indonesia is still affected by the strong earthquake that took place and the Tsunami. I do not think we should be surprised if another strong (stronger than today) happens...

What do you think?

I am sure I am not the only one who thinks some areas are becoming very active these days, say for instance, Indonesia, Fiji, Japan and Tonga.

Tectonic Plates or volcanoes?
One or the other, something is shaking and increases the possibilities for another major quake or volcano eruption.

I actually "think" I felt this one just now.
And I am 3 hours inland from Vancouver.
