Quake Watch 2010

Puterman... is this a fake with the Megaquakes??????

Wasn't sure whether to post this on Volcano Watch 2010 (which is a small Topic with few readers) or here, so I did both

22 quake swarm at Mt. Tarawera/Okataina Volcano, North Island, New Zealand last night.

Don't know if this has any relationsip to the Philippines/Fiji Deep quakes lately, but it has been pretty quiet under this volcano for a long while.
Definitely volcanic (not tectonic) in origin, just check the depths.

Seems to have tapered off, not much in the last 8 hours according to the seismograph.

Sorry Folk - There is Nothing to Worry About - - Just keep telling yourself that

I wonder how long "South of Java" has been "NW of Australia"
Both are geographically correct, but the quake is closer to java.

Must be political, the geologists feeling sorry for the Aussies being left out of the Global Shake Down

Perhaps this is another stupid question, but does anyone know why this graph: earthquake.usgs.gov... show two M8 - 9.9 quakes this year? I thought it only were one this year (Chile, M8.8) or has there been another one that I have missed? The second M8 - 9.9 must have come up quite recently, so where did it happen?

Only 1 8+ listed on USGS significant quakes:

earthquake.usgs.gov...

Well spotted...

I don't know how to read a seismograph, so I wanted to see if one of you could go look at this and tell me what it is.....on the ANSS section at USGS....EVERY seismograph looks like it is showing something happening at aprox the same spot here in the states.....Like I said, I don't know what it is, but I am curious to know what could cause them to all have this from Michigan to Texas...... www.liss.org...

I wonder if that's a global reaction to the deep-quakes at Moro Gulf that occurred earlier today - about the time of that global signal - although they weren't very big at just 4.9 and a 4.8... but the depth might be the reason.

reply to post by StealthyKat


These are all reacting to the 6.0 in Tonga

Data from station AFI (Afiamalu, Samoa)

It rattled round the world and even showed in Greenland and Finland which are the seismos I first spotted it on.

earthquake.usgs.gov...

there were 1 Magnitude 8 Quake in the United States in 2010???

reply to post by MoorfNZ

Thank You for responding! It sure looked like they were all related because the signature was pretty much in the same spot on every seismograph...

reply to post by PuterMan

WOW.....that is amazing! Thanks for the answer....I was really curious about that...

"04/02/10 - Errant email reporting a magnitude 8.0 earthquake near the Dominican Republic
2010 April 2

U.S. Geological Survey Earthquake Hazards Program Latest Earthquakes Users of the USGS Earthquake Notification System received a message reporting a magnitude 8.0 earthquake near the Dominican Republic. This was a mistake. In an effort to increase our ability to detect smaller earthquakes in the Caribbean region following the January 12th earthquake in Haiti, the USGS began accepting earthquake locations and magnitudes from additional sources in the region. The message reporting a magnitude 8.0 earthquake near the Dominican Republic was incorrect and resulted in the distribution of the errant e-mail. We acknowledge this was a serious mistake and have issued a correction."

They may have counted the earthquake?

reply to post by rasalhague

There has only been one, the next closest to an 8 were 2 x 7.7s, one off Simeulue, Sumatra on 6th April and one off Nicobar is. on 12th June.

USGS do some great work, but they do make a lot of mistakes.

They use various types of magnitudes for quakes as well, which messes with the data when you are trying to formulate the overall picture.
Those graphs are way off target, it looks to me like they are trying to prove that things aren't getting worse, when in fact they are.
For example in 2007 they show 18 quakes Mag7+, when in fact there were 30 of them.

I am doing a spare time project (with some help from Puterman) tabulating all the data from all the Global Networks that have web sites, and from Historical data from China and Japan.
The actual numbers are way bigger than what USGS show.
for example the only year they got right in the period 2000-2009 was 2002.

Puterman sent me a Chinese link the other day, I'm having to do a crash course in Manadarin , their data lifts the numbers I already have (which are already higher than USGS) by another 30-40% becasue they use Ms (Surface Wave Magnitude) as a magnitude type for their lists.

The Earthquake Numbers Project (doesn't include the 3 Philippines quakes yet)

Its something we were taught in school, never rely on just one source, cross check your information if you can.
Too bad the media didn't get taught that too

Hey thats a good signature line

I wonder how high the actual number was 1995, when there was about 20+ M7.0-7.9 registered by the USGS (or perhaps I saw it somewhere else)? Do you have any way to check that?

Do you know what could account for the increase in earthquakes? Isostasy? How far back do your research go?

reply to post by rasalhague


I found 24 for 1995, and thats using usgs own data !! (the best source of usgs data is noaa or anss which are sub-divisions or associated with usgs).
The source of each event is on the popup tag off the maps.

I've gone back to 1930 so far, if you scroll down the right hand column you'll see "categories", selecting from the drop down list will jump you to the decade.
Its a big project, especially trying to find background information to put on the popup tags on the maps.
All the graphs at the start relate to the graphs under each decade, then hense to each graph for each year.

Holy Cow check out all the aftershocks of that Quebec quake, I hadn't followed that one

Looking at the USGS world quake map I suddenly had the urge to thumb my nose and shout "ner ner nah ner ner - our quakes are bigger than yours" across the Pacific to the USA .. then realized I might be tempting fate
