Check out the depth!!!! This will be 'felt' on siesmos around the world.

Edit to add: I don't usually start threads on earthquakes, but just add info to the quake thread. However, the depth on this moderately large quake is VERY deep, and therefore (IMHO) deserves a little extra attention.

wow

I was just at USGS not ten minutes ago.

Good catch WC

mega deep Depth
603.8 km (375.2 miles)

reply to post by berkeleygal


I know, that's why I started the thread. (I just added a comment to the OP)

I wanted to curtail any threads similar to what happened last time we had a large, very deep quake. Remember? It showed up on seismos around the world so several people thought it was world-wide quake.

reply to post by westcoast


I do remember..

silly peeples

thanks for the pointing to the depth. I would have overlooked that. Not being versed in seismic science, can you tell me what it the import of the deeper quakes as opposed to shallower? Thanks. And thanks for posting this thread

The Moro Gulf just had two really big ones, a 6.9 and a 7.2 which was just removed, lol, at about 5:32 p.m. Central Standard Time, United States.

Silly USGS, tricks are for kids...

Poor Philippines, do you think that undersea volcano is getting ready to blow?

I picked up a 7.1 first.
With a 6.9 aftershock not even 10 minutes later.

Hmmm firefox isn't showing it anymore. Only the 6.9.
It was enough to make me stop what I was doing.
Anyone else see the 7.1 go off?

reply to post by Copperflower


Thank you I know I'm not crazy, I saw 2 big ones go off.

Does the USGS usually jump so quickly to hide data?

At least the depth means no chance of Tsunami, and much less destruction that one closer to the surface would cause. Still something to monitor without a doubt.

Good find.

Plenty of Twitter reports of a 7.1. The suggestion is there will be little damage due to the depth.

reply to post by ThirdJohnAdams


I saw the 7.1 on my firefox alert. Then another alert was issued, this time, was downgraded to 6.9. Same quake tho, I believe

Okay, so yeah, there appears to still be some deabte as to the size of the quake. here is the current list of quakes on USGS

While it isn't unusuall for them to change it after review, I don't think I have seen it differ between the list and the info. Interesting!



As to why it is important for depth: Some think it can have a bigger impact on other existing faults (me included) and that you typically can see it on seismos all around the world from it (picking up the P waves)


For more info on quakes, I would recommend browsing the USGS site. They have some GREAT stuff!!

Okay....oficially upgraded to 7.3!!!

Just a note of interest: It is starting to show up on the live seismos around the world. Check them out HERE


This is a BIG quake to have at that depth. It will be very interesting to see what(if any) impact it could have on other vulnerable or unstable spots.

I am in Manila at the moment ,didnt feel anything here but Mindanao is not that close to Luzon.I have been a little uneasy about going into shopping centers or buildings ever since i arrived mainly because of a dream i had a couple of months ago regarding an earthquake .

Now listed twice!

This second 7.4 is indeed a second event and not the same one as listed above. They are getting rocked hard there right now.

There was also just a 5.4 aftershock in there too.
