Phivolcs: No tsunami threat to PHL

Filipino seismologists on Friday allayed fears that a magnitude-7.3 quake that hit Japan could generate a tsunami reaching the Philippines.

I have strong emotional connections with Japan.

Yes, a highly fragile part of the globe.

I hesitate to say 'Climate Change', but the warnings have been stronger and stronger in recent years.
Some 'experts' suggest natural cycles.

But like you Steve, I do wonder what is going on with our planet.

When you consider that England and Scotland were geographically separated by an ocean and both in the southern hemisphere and that the antarctic enjoyed a tropical rainforest type climate once, then what we are seeing these days is quite normal.

The world is constantly changing. The activity in the Pacific ring of fire, that include the Philippines and Japan, is just part of that "evolution".

Hmmm.

Hmmm.

Typical engineer. :biggrin:

Anybody got a better theory?

A map depicting all the worlds eartquakes since 1898. Notice how the Pacific "Ring" is most prominent. This demonstrates how active the Pacific region is tectonically.

It is generally accepted that the activity is down to the surface plates in the region moving. And the northern and western perimeter of the "Ring" is where one plate or plates are subducted under another. The Philippines is in there somewhere, covered in neon green.
