Earthquakes In Diverse Places
New Zealand: Another large Earthquake rocks Canterbury
Last updated 12:15 06/06/2011
Cantabrians have been shaken by two aftershocks this morning,
forcing some stores near the epicentre to close.
The first earthquake struck near Rolleston at 9.09am at a depth of
15 kilometres and measured magnitude 5.5.
People who have damage as a result of the tremor will need to
lodge a new claim with the Earthquake Commission by September 6 as
it is considered a 'new event' for insurance purposes.
The Canterbury Quake Live website reported the shake was the sixth
largest since September 4's magnitude-7.1 quake.
It was followed by a magnitude 3.8 tremor at 11.41am. This
10km-deep shake was centred in Weedons, about 4 km away from
Rolleston.
GNS Science duty seismologist Brian Ferris said the 5.5 tremor was
"within the forecast we expected".
It was not a sign of "anything big" to come, but it was likely
that small aftershocks would follow today's quake.
"It's possible there'll be an increase in activity in the area,
but it's unlikely anything as big will occur," he said.
RED ZONE MOVEMENT
A Christchurch Earthquake Recovery Authority (Cera) spokesman said
indicator buildings in Christchurch's red zone experienced a
"small amount of movement".
The eight indicator buildings, of differing construction types,
are located throughout the CBD. Any faults in the buildings are
monitored for changes after each significant aftershock.
The spokesman said today's aftershock had not caused "any great
concerns" and CERA had not restricted access to the red zone.
"There's no immediate danger, but we are keeping an eye on it," he
said.
Regular inspections of the indicator buildings and work in the red
zone would continue as normal, he said.
MESSY BUSINESS
Fay Burson, manager of bottle store Henry's in Rolleston, said she
probably lost more stock during today's shake than in February's
magnitude-6.3.
"It was a very severe initial jolt after a bit of a lull."
The shop was still open.
Burson said September's earthquake was much worse.
"We had minor damage, nothing compared to our first one of
course."
The Warehouse in Rolleston has closed for a few hours after stock
fell off shelves during the shake.
Stockroom worker Jo Edmond said she was feeling "a little bit
nervous".
The store still had power but would be closed for a few hours
while staff cleaned up, she said.
"The store's a bit of a mess. There's a lot of glass, but nothing
too bad."
She said there were not many customers in the store at the time,
and off-duty staff had come in to help with the cleanup.
Damaged and fallen stock saw New World Rolleston close immediately
after the tremor, owner Roy Bridgman said.
However, the store was ready to reopen shortly before 11am.
"Our staff are all fine. We just cleaned the shop straight away."
Bridgman said he was at home getting ready for work when the
aftershock hit.
"You never get used to it, but it's a fact of life and you just
have to carry on."
Ad Feedback
Westfield Riccarton public relations manager Deb McGhie said most
of the mall was still closed at the time of the aftershock because
of the public holiday.
The Pak 'n Save supermarket was open and "lost only about half a
dozen shampoo bottles".
McGhie said engineers were monitoring the building, but there were
no concerns about damage.
Retailers were told they could close or evacuate, but everyone had
opened as normal, she said.
FEW KNOWN PROBLEMS
A Christchurch City Council spokeswoman said no "matters of
concern" had been reported after this morning's aftershock.
A water outage in Cashmere last night was unrelated to today's
quake, and water had been restored to the area this morning, she
said.
A Fire Service shift manager said two alarms were activated after
the shake, but both were false alarms.
"We had no calls from the public. I think people are now going and
checking everything before they call, whereas before they'd just
call us straight away," he said.
Police said there had been no reports of damage.
Meanwhile, an unrelated power outage cut electricity in parts of
Fendalton and Ilam for just over an hour this morning.
A cable fault cut power at 8.23am, but repair crews had it
restored by 9.36am.
ROLLING RUGBY
Spectators and players at a rugby tournament for four to 16
year-olds in Rolleston saw the ground "roll" during this morning's
aftershock.
The tournament, involving 42 teams, kicked off just before the
tremor struck, but it did not stop the players for long, Rolleston
Rugby Club president David Egan said.
"Everyone stopped and looked, then carried on. Everyone's come to
expect them now."
Some people reported seeing the jolt hit the ground, he said.
"They could see it rolling, heading towards the clubhouse. It hit
the car park first and lifted some vehicles off the ground, then
hit the clubhouse."
Egan said a "few cans and bottles" fell over inside the clubhouse,
but there was no other damage.
FELT AROUND SOUTH ISLAND
Twitter users across Christchurch reported feeling the quake, with
some saying it had knocked items off shelves.
People reported feeling the quake in Hawarden, Akaroa and as far
away as Dunedin and Nelson.
Colleen Simpson, in St Albans, said: "Our cupboards all opened and
water sloshed out of the sink and fish tank."
Ellen Martin, 20, of Dunedin, said the aftershock was "scary".
She was visiting family in Rolleston and said several ornaments
were broken in the house during the quake.
She felt the February 22 quake in Dunedin but said she was "not
used" to feeling tremors like thi
