There is a very interesting Graph here:

Horizon Project Increase in Large Earthquakes Historical


Which seems to show a massive increase in large earthquakes recently, and is quite a striking Page (flash required)

Some have attempted to debunk this but the Data source has been confirmed as the USGS here:

USGS Historic Worldwide Earthquakes of Interest

So I can only assume they (usgs) have only included the data sets that involve quakes that are unusual, significant and or caused major damage or destruction to life or property.

If you look at a data set f all large earthquakes on this time frame the bar graph is not soo extreme, but still rises recently, however as human beings obviously the data interpretated is important as it shows that quakes seem to be happening more and more in areas of human habitation.

I initially thought about population increases however when you look at the graph you will see that the rise is much more recent for that to be statistically significant and a driving factor.

Huh...Syria, Dead Sea Region, Gibraltar & Yemen...I don't remember these being popular EQ regions...anyone know the Seismic History of these areas?

I am a bit surprised I haven't found a mention of the latest seattle quake.

No tsunami warning yet.

Okay very very strange!!!!!

The 6.0 in my above post in Japan, happened at EXACTLY the same time, to the second, could be a major slip happening is deep 35km, time as another 6.0 a little further away and different depth!!!

First 6.0 as this link and posted above: 1

and this below at the same time exactly:

Very strange indeed exactly same depth and time and very close to the coast of Japan, no sign of tsunami warning.

Elf.

Ignore the below and above they have been resolved into one quake and one event,

Strange how USGS and Seismic International showed two very very different locations though, quite some distance apart, japan is very close to the Korean situation building at the moment....

Harp?

.............................................................................................

Here is the provisional telemetry for the 6.0 quakes in japan.

1

Why no P waves for either?

Why are they both not showing as even if in synch due to the same time start they would register different as from different locations.

Strange indeed.

As I was looking around for NW US Fault lines Ect, I came across one that kind of looked familiar...take a look at this link...

www.abovetopsecret.com...

Think there's anything to my reasoning?

Ok now...that's 6 in Randsburg, CA area in last 10 Hrs (21:09-07:14 UTC)...right at the Garlock & Owens Valley Fault intersection...wonder if this will transfer stress west to San Andreas being as Garlock is a left handed slip fault?


I see 2 M7+'s of past, off Garlock/San Andrea...Bakersfield & San Bernardino areas.

Small Earthquake Rattles New Jersey

Published: February 3, 2009

The earthquake, with a preliminary magnitude of 3.0, struck just after 10:30 p.m.; the epicenter was reported at Victory Gardens, although it could be felt in Rockaway, Dover and Morris Plains, according to Won-Young Kim, a seismologist for the Lamont-Doherty Earth Observatory, in Palisades, N.Y.

I have an important piece of information to share with you today.

recently I took out a full spectrum homeowners insurance policy and after debating with my carrier, Capstone insurer's about the necessity of having EQ insurance, they told me that they would attempt to find anyone that would grant me the coverage I requested. They also told me that there was currently a moratorium on EQ insurance until further notice.

Today I received a letter from Capstone informing me of the following, (I Would have simply snapped off a photo, but camera is at school with my son for a project).

If you doubt me, just say the word and I will gladly post the letter later tonight.

J.
I wanted to let you know that we contacted the company your home is insured with, and they are currently not offering EQ coverage. We checked with several companies and they all have a hold on offering EQ insurance coverage. Next year when your policy renews you may want us to look into it for you again.
Thank you for your business!

Well, what is up with this and how many of you currently have EQ insurance in your policies? Furthermore if you do not mind, I ask that you take a minute and call your insurance company and ask if it available. Is this just in the Midwest or everywhere? Is New Madras going to go?

Does this mean that they know something? And one other odd thing which appreared on my coverage this time was civil unrest and rioting. I live way way out in the boonies, and it would be a huge stretch to think of civil unrest out here...

Tsunami Alert has been issued for Jakarta after the7.5 quake,

The U.S. Geological Survey said the 7.0-magnitude quake was centered 195 miles (315 kilometers) from Manado, the northernmost city on Sulawesi island. It said it had a depth of about 20 miles (30 kilometers) beneath the ocean floor.

Kinda deep, so hopefully not to much damage,
