Yesterday's thread - different earthquake, same neck of the woods...

Magnitude 6.3 - SULAWESI, INDONESIA

Also not full moon related...

[RayChuang88]

That map of yours--despite the jesting remarks on the map--show why that part of the world is not only extremely vulnerable to earthquakes but also volcanic activity. It's similiar to the geology of the Pacific Northwest in many ways.

[NotJustAnotherPrettyFace]

LOL - some like-minded thinker obviously came up with that one! (Was it you? :-)

[ForGod'sSake]

'Spect so. Japan also?

Are they remaining aftershocks of a settling plate

-OR-

The ramp up to new activity?

[Bean Counter]

I wonder if this is another aftershock from the Dec 26 quake. The rupture on the tectonic plate under Indonesia was so huge, there are bound to be more large aftershocks as things settle down.

[Explorer89]

Prayers for the earth to settle down.

It can't. That corner of the earth has been grinding itself against itself for eons. Good book: "Krakatoa" about the 1883 volcano obliteration and ensuing tsunami, which was swept people off of hillsides over 100 feet above sea level. Krakatoa is between Sumatra and Java...right in the neighborhood of these last quakes.

[Zavien Doombringer]

Well, it has been prophesied..."Like a woman who trevails at birth.."

Signs of the times...

[RayChuang88]

'Spect so. Japan also?

Given the number of active volcanoes on Hokkaido and Kyushu, so very true. And northeast of Japan is Russia's Kamkatchka (sp?) Peninsula, which is on the fault that is part of the Ring of Fire and home to several quite active volcanoes, too.

[NotJustAnotherPrettyFace]

Excellent! Are you a graphic artist? Photoshopper? (just curious)

[ForGod'sSake]

"Krakatoa" about the 1883 volcano obliteration and ensuing tsunami, which was swept people off of hillsides over 100 feet above sea level.

Lest we forget, TOBA, that would make Krakatoa look like a firecracker. The initial quake was just offshore from this very old caldera.

Toba, Indonesia

75,000 years ago

Landsat Multi-Spectral Scanner (MSS) image taken Oct 3, 1973.

Why is there a giant lake - 100km long and 30 km wide - in the middle of the Indonesia island of Sumatra? Lakes often form in depressions caused by glacial erosion (Great Lakes of USA) or by down-dropping of large blocks of the crust (the lakes of East Africa), but such gentle processes didn't cause Lake Toba in Sumatra.

In 1949 the Dutch geologist van Bemmelen reported that Lake Toba was surrounded by a vast layer of ignimbrite rocks. Toba was apparently a huge volcano! Later researchers found rhyolite ash similar to that in the ignimbrite around Toba in Malaysia and even 3000 km away in India. And oceanographers discovered a vast dusting of Toba ash on the floor of the eastern Indian Ocean and the Bay of Bengal. These scientists quickly realized that the Toba eruption, dated at 75,000 years ago, was the most recent truely large eruption on Earth. Bill Rose and Craig Chesner of Michigan Technological University combined all the information on the extent of the Toba volcanic material to deduce that the total amount of erupted material was about 2,800 km3. About 800 km3 was ignimbrite that travelled swiftly over the ground away from the volcano destroying everything in its path, and the remaining 2,000 km3 fell as ash, with the wind blowing most of it to the west. Such a huge eruption probably lasted nearly two weeks. Very few plants, animals or humans around this part of Indonesia would have survived.

The eruption of such a huge amount of volcanic rock, which was previously beneath the earth's surface, naturally caused a great collapse to occur. The collapse formed a caldera, which filled with water creating Lake Toba. Later, the floor of the caldera was uplifted to form Samosir, the large island in the lake. Such uplifts are common in very large calderas, apparently due to the upward pressure of unerupted magma. Toba is probably the largest resurgent caldera on Earth.

There have been no historic eruptions of Toba, but large earthquakes have occurred, the most recent in 1987 along the southern shore of the lake.

Thanks for the kudos. I dabble. You can find one of my doodles HERE.

This shouldn't affect Cindy. Frankly, all us left-coasters are in the "ring of fire" ourselves and the next big one here could happen any time.

[TheBrotherhood]

You got it all wrong!

This was, and continues to be, Bush's fault.

[JudyinCanada]

Silly me, but of course it's Bush's fault. How could I have been so blind? I should have know when I saw all of those satanic salutes the other day!

[carumba]

I see Krakatoa on the map. I read many stories about that cataclysm when I was a kid.
