7.3 quake hits Philippines (upgrade from 6.9) VERY deep

I have friends and family in the Philippines. Hopefully all is well. 7.3 is huge though, isn't it?

Actually, the largest of the five has been a 7.6. Yes, it is considered a 'large' quake. At this depth, however, there most likely won't be too much local damage or a tsunami. More likely to be felt over a broader area, and P waves going around the world several times over.

Source: New York BNO NEws "The USGS estimated that around 21 million people likely perceived weak shaking as a result of the three large earthquakes, but said they were too deep to cause any damage. The Pacific Tsunami Warning Center said no tsunami had been generated as a result of the earthquakes, mostly due to the depth of the earthquakes. “A destructive tsunami was not generated based on earthquake and historical tsunami data,” the agency said in a bulletin.

I believe there are 1.69 km/mile...are those numbers right...?

I believe there are 2.2 km/mile...

to convert km to miles 1 miles = 9/5 km

IF I remember my conversion factors....it's been a while

EDIT: Never mind....that is for Fahrenheit to Celsius

1 miles = 1.609344 kilometers

Does ANYONE know of any damage anywhere???
a friend of mine is in that area.

These are 'some' of the deepest recorded quakes in answer to your question! I think the deepest is about 600 miles but I would need to check that.

Unbelievable, I have never seem anything like this.

I am sure it probably has happened before. The only good thing is that they are in between 3,300 an 4,800 metres of water.

Very unlikely to be any damage from these. Way too deep and steep.

120km = 75 miles
100km = 60 miles
80km = 50miles *exact
50km = 30 miles

All approximate. We have kilometres here bur all the car speedos are in miles (older ones)

hey guys, i am in Davao City right now and that's in Southern Mindanao. We felt the earthquake here and we're happy to inform you that we're all fine. I know nothing about earthquakes but relatives and friends all over the world are in panic to know that we were just struck by that strong of an earthquake.
We're all fine and no damages happened.

Glad to hear all is OK with you there.

Did you feel all the quakes? What did they feel like?
Rolling or a big jolt?

Found it.

Deepest recorded quake 720 km

The deepest-ever recorded earthquake began over 720 km down.

720 kilometer = 447.387 258 41 mile Convert here
(I was wrong about 600m, must have been thinking metres - gets very confusing these days)

Thanks for the info Puterman! I thought so....it'll be interesting to see what happens over the next few days!

From Google Earth the deepest of those was

Depth: 616.70 km (383.20 mi)

Don't forget there was a 6.1 there on the 21st about 400 miles SE which may seem a long way away but is on the subduction zone/fault.

Edit: The larger green one

I think the 6.1 is a very good point to bring up! It was 102km deep, while not near as deep as these ones, that is still considered a 'deep' quake.

Here is a list of recent quakes for that area:

So are you thinking precursers? I imagine we will either see a bit more in the philippines or else something opposite it in the ring of fire.

i could only speak of the first aftershock -- the initial earthquake happened i was still asleep and didn't feel anything --- the aftershock lasted about 2 minutes -- no big jolt or rolling effect --- just a little sway of maybe an inch back and forth (do you know what i mean?) -- almost possible not to feel anything (most of my friends didn't feel it).
2nd aftershock was a little stronger than the first one -- maybe swayed 2 inches back and forth but lasted only about 30 seconds.

btw, i am approximately 152 kms / 108 miles from Cotabato.

Thank you for the personal account! Please let us know of anything else that happens.

Also, FYI incase you didn't already know, the third quake was actually the largest, at 7.6 mag. Given the way these are playing out, I'm not so sure we are looking at aftershocks yet.

Just had another one:

3 x 7?

It's Roald playing Blackjack!

Edit: Haven't got that 5.4 yet. eQuake is showing 4.9 for 01:50, which I have as 00:50. Very odd.

You're right. It seems that all the dots do not connect with these quakes. Do you think because they are so deep, there are some discrepencies? IDK...these are just very unusuall, as well as the reporting.

still waiting to see what pans out
