Now check this out, a recent update at EMSC has 3 big quakes at New Britian

MAG, UTC TIME, LAT, LONG, DEPTH
7.1 Mw 2010-07-18 13:04:12.0, -6.05, 150.51, 40
7.2 Mw 2010-07-18 13:35:01.4, -6.00, 150.59, 40
6.2 mb 2010-07-18 13:35:02.0, -6.04, 150.57, 40

The Aussies are back on line , and they have the first one smaller too

MAG, UTC TIME, LAT, LONG, DEPTH
18/07/2010, 13:04:14, -6.1767, 150.6275 60, 6.9
18/07/2010, 13:35:00, -6.2878, 150.6673, 18, 7.3

www.ga.gov.au...

I think this seismograph shows both quakes quite clearly, the first one does look bigger.
Coen siesmo

This one just shows the 2nd quake
Coen siesmo 2nd quake

you can see 2 definite peaks, could that be the 6.2 that EMSC see 2 seconds after their 7.2?

I think this is more "complex" than USGS is letting on;
"complex" earthquakes are quite common, where there are multiple events within several seconds which at first look like one quake.

I have come across a few while doing the research for my blog, seems to happen a lot in Burma and Vanuatu, and I just came across these 2 today from 1997

Magnitude 7.8
Date-Time 1997 10 14 09:53:18 UTC
Location 22.10S 176.77W
Depth 167 kilometers
Region South of Fiji Islands
Felt at Wellington, New Zealand. Complex earthquake, with two events occurring about 6 and 12 seconds after the onset

Magnitude 7.8
Date-Time 1997 12 05 11:26:54 UTC
Location 54.84N 162.03E
Depth 33 kilometers
Region Near East Coast of Kamchatka
Felt (VII) in the epicentral area and (V) at Petropavlovsk-Kamchatskiy and Ust-Kamchatsk. Felt (II) at Severo-Kurilsk, Paramushir. Also felt aboard the cargo ship Stepan Krasheninnikov in the epicentral area. Tsunami generated with recorded wave heights (peak-to-trough) at the following selected tide stations: 15 cm on Adak and Unalaska, Alaska; 60 cm at Kahului, 52 cm at Haleiwa, 47 cm at Hilo, 30 cm at Hanalei, 12 cm on Midway, 10 cm at Snug Harbor and 5 cm at Honolulu, Hawaii.
Complex earthquake with at least one event occurring about 14 seconds after the onset.

I'm going with EMSC's information for now ( 2 x 7+'s)

Small quakes but I wanted to mention this because the last one are located 7 miles from the M 7.9, quake that hit Central Alaska in November 03, 2002 22:12:41 UTC and who had quite an effect on Yellowstone.

Off topic but has anyone got links to volcanic activity for the pacific?
Trying to find out which volcanos are active or have becoime active recently?

Does anyone else feel like this is something building up, rather than a series of aftershocks from the 6.7?

There are tons of volcanoes active in the Pacific. A good place to go to find out the latest news is the Eruptions blog - a good community of commenters there, too. scienceblogs.com...

Thanks for pointing out that link to Yellowstone from Alaska.. what effect did it have on Yellowstone, swarm or larger events etc?

1946 Aleutian Islands earthquake From Wikipedia, the free encyclopedia Jump to: navigation, search 1946 Aleutian Islands earthquake Residents run from an approaching tsunami in Hilo, Hawai'i Date 1 April 1946 12:28 (1946-04-01T12:28)(UTC) Magnitude 7.8 Ms Depth 25 kilometers (16 mi) Epicenter location 52°48′N 163°30′W / 52.8°N 163.5°W / 52.8; -163.5 Countries or regions affected USA, Hawaii, Alaska Tsunami Yes Casualties 165 The 1946 Aleutian Islands earthquake was an earthquake near the Aleutian Islands on April 1, 1946. It was followed by a Pacific-wide tsunami. The earthquake was a magnitude 7.8, with its epicenter at 52.8°N, 163.5°W, and focal depth of 25 km. It resulted in 165 casualties (159 people on Hawaii and six in Alaska) and over $26 million in damages. Among others, it obliterated the Scotch Cap Lighthouse on Unimak Island, Alaska and killed all five lighthouse keepers. The wave reached Kauai 4.5 hours after the quake, and Hilo 4.9 hours later. This prompted the creation of the Seismic Sea Wave Warning System, which later became the Pacific Tsunami Warning Center in 1949.[1] The tsunami was unusually powerful for the size of the earthquake; it was the last time any earthquake below magnitude 9.0 caused tsunami fatalities far from the earthquake area. Scientists think the tsunami may have been caused by an earthquake triggering an underwater landslide.

The last one (so far) is another 5.0!

There has been a lot of energy released in a short amount of time. It is a n impressive swarm, and I get the feeling it is builing too.

The Alaskan quake of November 3, 2002 triggered a swarm at Yellowstone and changed the geysers and hot springs. You can read about it Here.
