I mentioned the first swarm of 11/12/13 July UTC here
I counted 31 quakes in the 19/20 July UTC swarm.

probably too cold and covered in snow anyway, but not a good time to do the Tongariro Crossing walk
Where these are happening on the north flank there are already steam vents.


I think you are getting your volcano's mixed up though

Tongariro last erupted on June 10. 1886. Approximately 1 and 2 cubic km of basaltic lava erupted from its fissure, destroying its pre-existing dome complex over a length of 8km and extended a further 9km to the SW. The eruption sadly destroyed the famous pink and white terraces, at Rotomahana. The eruption also killed about 120 people and spread ash over an area of over 10000 square kilometers.

Thats about Tarawera, 130km to the north.

Tongariro is a Volcanic Complex, not just a single volcano.
Ngarahoe is the youngest part of Tongariro, last eruption 1977. (I remember that, driving the Desert Rd Auckland to Wellington and seeing the cone smoking)
The last activity on Tongariro north flank (Ketetahi) itself was 1927 VE1, Red Crater 1926 VE2

Best interactive map I have at the moment is the 30 Day NZ
here it is set on Tongariro

I'll do a page on it at eqarchives when I get some time, split the timelines etc

Bit of a disturbance down east of Cape Farewell too at the same time

Geonet Rapid not doing such a good job on this Tongariro swarm
only showing 23 of the 31 that the main preliminary database have.
Geonet Rapid mapped

I've done some cross matching over the last few weeks, confirmed results are poor.
They may show in a month or so.
I'll keep archiving the data anyway, Geonet Rapid is pretty easy, the time is already set out yyyy/mm/dd hh/mm/ss format so that saves time on Excel.

Another 7 quakes in the swarm since I posted the last map.
Just popped home for lunch, be back in a couple of hours and do the update.

here ya go Mt. Tongariro Swarm
7 maps and the list
pretty colours, lots of numbers, mostly aqua and green

My thoughts are that this will fizzle away, although the magnitudes have gone up to the low 2's they have spread away NW towards Lake Roto-aira (a location well known for its own swarms of micro quakes)
If the mags go up to the 3's and 4's then something might blow.
Will update again in the morning.

Over 50 aftershocks detected after E China quake
Updated: 2012-07-21 13:16:00

NANJING, July 21 (Xinhua) -- A total of 53 aftershocks have been detected as of 7:30 a.m. Saturday after a 4.9-magnitude earthquake jolted east China's city of Yangzhou Friday night, local officials said.

Most of the aftershocks were of a lower scale, with only four measuring between 3- to 4-magnitude, said Zhang Zhenya, deputy director and spokesman for the Jiangsu provincial earthquake bureau.

Seismic experts predict that a devastating earthquake is unlikely to occur, according to Zhang.

Friday's earthquake hit Yangzhou at 8:11 p.m., according to the China Earthquake Networks Center.

The quake left one person dead and another slightly injured as of Saturday noon, Zhang said.

Calafornia doing some "rockin" and "rollin" in the last few hours....has anyone felt anything.

dont worry...just saw the thread thats been started.

It it kind of crazy how the sequence of quakes creates a teeter totter effect.

Does anyone have an idea as to what would cause this back and forth tug of war??

What I mean is #1 is west, 2 is east, 3 is west, and so on.

reply to post by radpetey


yeah I noticed that too
being located beneath the overlaying edge of the Plate and looking at the various depths (33 ,60, 40km) you would think maybe the left hand ones would be the 60km and the right hand ones 30km, (like the Pacific Plate bends down left to right) but thats not the case.

still on the see-saw effect subject at Onekotan Island
not exactly what I was after, but RAS don't have a historical search thingy so i had to use ANSS for this, and their locations and depths are different from RAS for the quakes on the 20th July, the deepest being 22km.
however. from this you can see the majority of the quakes in the cross section are within the overlaying plate.
yellow circles in the map and yellow triangles on the graph are the 20th quakes ( ANSS source, data covers the period 28/01/2002 to 20/07/2012, Mag 4+, 115 events, the largest being a 6.1Mw on 28/01/2002)

School funded by Republic of Congo completed in quake-hit Chinese county
English.news.cn 2012-07-22 22:41:13

news.xinhuanet.com/english/china/2012-07/22/c_131731457.htm

YUSHU, Qinghai, July 22 (Xinhua) -- Construction on an elementary school funded by the Republic of Congo was completed on Sunday in Yushu, a quake-hit Tibetan prefecture in west China.

The school, located in Yushu's Chengduo county, was built with the help of 16 million yuan (about 2.51 million U.S. dollars) donated by the Republic of Congo.

Although our economic capacity is limited, we should extend the help, said Foreign Minister of the Republic of Congo Basile Ikouebe at a ceremony held to commemorate the completion.

Denis Sassou Nguesso, president of the Republic of Congo, expressed his country's willingness to donate while attending the 2010 Shanghai World Expo.

A 7.1-magnitude earthquake struck Yushu and killed 2,698 people in April 2010.

China initially suggested that the Republic of Congo make a less expensive donation for fear of burdening the African country. However, China finally decided to accept the assistance because of the insistence of the Republic of Congo.

The friendship is mutual, as China has also offered us much assistance, said Basile Ikouebe, noting that China helped the Republic of Congo to repair roads after an explosion impaired one of the country's military factories.

Proccessed some data I downloaded on July 6th
could be too many interactive maps on one page, takes forever to load.
Canterbury Series, NZ 2010 to 2012
not sure if its Google, Wordpress or my ISP thats at fault for the slowload up.
heres a couple of screenshots anyway. If they won't load I may have to revert to a static map and link each one to single GMaps pages. Its the last 3 that won't come on 100%.
therer are only 33,000+/- icons on the page

this is the mag 5+ quakes colour coded and numbered


this is a screenshot centred on Rolleston, off the main 11.000 quake map

US pledge to rebuild Haiti not being met
By MARTHA MENDOZA and TRENTON DANIEL | Associated Press – Sat, Jul 21, 2012

news.yahoo.com/us-pledge-rebuild-haiti-not-being-met-170346036.html

(...)

Until now, comprehensive details about who is receiving U.S. funds and how they are spending them have not been released. Contracts, budgets and a 300-item spreadsheet obtained by The Associated Press under a Freedom of Information Act request show:

— Of the $988 million spent so far, a quarter went toward debt relief to unburden the hemisphere's poorest nation of repayments. But after Haiti's loans were paid off, the government began borrowing again: $657 million so far, largely for oil imports rather than development projects.

— Less than 12 percent of the reconstruction money sent to Haiti after the earthquake has gone toward energy, shelter, ports or other infrastructure. At least a third, $329 million, went to projects that were awarded before the 2010 catastrophe and had little to do with the recovery — such as HIV/AIDS programs.

— Half of the $1.8 billion the U.S. promised for rebuilding is still in the Treasury, its disbursement stymied by an understaffed U.S. Embassy in Port-au-Prince in the months after the quake and by a Haitian government that was barely functional for more than a year.

— Despite State Department promises to keep spending public, some members of Congress and watchdogs say they aren't getting detailed information about how the millions are being spent, as dozens of contractors working for the U.S. government in Haiti leave a complex money trail.

After the earthquake in Haiti, over 600,000 people left the capital Port-au-Prince, and over a million people were left homeless. With the help of mobile data provided by Digicel, the largest mobile operator in Haiti, the researchers looked for patterns in the movements of two million anonymous mobile users.

Abstract

Most severe disasters cause large population movements. These movements make it difficult for relief organizations to efficiently reach people in need. Understanding and predicting the locations of affected people during disasters is key to effective humanitarian relief operations and to long-term societal reconstruction. We collaborated with the largest mobile phone operator in Haiti (Digicel) and analyzed the movements of 1.9 million mobile phone users during the period from 42 d before, to 341 d after the devastating Haiti earthquake of January 12, 2010. Nineteen days after the earthquake, population movements had caused the population of the capital Port-au-Prince to decrease by an estimated 23%. Both the travel distances and size of people’s movement trajectories grew after the earthquake. These findings, in combination with the disorder that was present after the disaster, suggest that people’s movements would have become less predictable. Instead, the predictability of people’s trajectories remained high and even increased slightly during the three-month period after the earthquake. Moreover, the destinations of people who left the capital during the first three weeks after the earthquake was highly correlated with their mobility patterns during normal times, and specifically with the locations in which people had significant social bonds. For the people who left Port-au-Prince, the duration of their stay outside the city, as well as the time for their return, all followed a skewed, fat-tailed distribution. The findings suggest that population movements during disasters may be significantly more predictable than previously thought.
