This is a substantial quake! Prayers going out...

1. It was almost 400 miles down

and 75 miles from a population center. I doubt there is any damage, although it was strong enough at that depth to rattle nerves.

2. Plus 2 more at about the same magnitude.... Wow.

3. “Some of our Muslim neighbors fired their weapons to drive away bad spirits,” she said.

This from another article. I thought noise-making to ward off bad spirits was a Chinese thing. At least that's what I think the purpose of the firecrackers is. But Muslims?

4. Oh, that whole area is so interconnected...

They sold silk and horses and spices, gold and copper and tin...they all knew each other.

10. Insular SE Asia is about as syncretic as it gets

Just about everyone got some population represented there after awhile, and each group started influencing all the others.

5. Earthquakes strike waters south of Philippines

A series of four strong earthquakes spanning just over an hour struck the Philippines' Moro Gulf on Saturday morning, according to the U.S. Geological Survey.

Three of the four earthquakes had magnitudes between 7.3 and 7.6; the other came in at a 5.4 magnitude. The first quake struck at 6:08 a.m. (6:08 p.m. ET Friday) and the fourth hit at 7:15 a.m. The last quake ran the deepest at 616 (382 miles) kilometers.

The epicenters of the quakes were about 100 kilometers (62 miles) off the coastal city of Cotabato and roughly 950 kilometers (590 miles) southeast of Manila.

No tsunami warning was immediately issued for any of the quakes.

There were no reports of damage, said Rona Faeldin of the Philippines Coast Guard.

that is all

6. They were also nearly 400 miles deep

Depth is as important as magnitude.

While such deep quakes might eventually be echoed on the surface, they don't do damage in and of themselves.

7. 400 miles deep? Is that possible? Wow !

[Warpy]

8. It's actually in the mesosphere

the mid portion of the liquid mantle, so who the hell knows what's going on in there? Fluids get really strange at that depth.

9. There was also a smaller quake off the coast of California

near San Francisco. The radio said it was a 3.4...or something. It occured at almost the same time...around 3pm PST.
