Magnitude 7.0 earthquake gently rocks Wellington, NZ

May 28, 2015 – NEW ZEALAND - The
equivalent of a magnitude 7 quake is quietly rocking the capital,
though until now you’d have only noticed it if you were a geophysicist.
The huge underground movement called the Kapiti Slip is responsible, and
it’s not over yet. “This is what we call a silent earthquake,” Geonet
scientist Caroline Little said on Firstline this morning. “Instead of
this movement happening in seconds, this will take around a year to
move.” Normal earthquakes release all their energy when one side of a
fault suddenly slips past the other, and can be incredibly destructive –
as the people of Christchurch know all too well. But in a silent
earthquake the energy is released slowly, and in some cases can be
predicted in advance. “We started recording with the GPS network in
2002, and since then this is the third Kapiti event we’ve seen,” says
Ms. Little. “Both of the previous two have lasted around the year mark.
Interestingly it’s occurred every five years – 2003, 2008 and then this
one in 2013.” Slow-slip quakes are relatively recent discovery, and
their effect on conventional quakes is still being researched. “It does
change the stress around the area, and these types of events have been
known to interact with conventional earthquakes,” says Ms Little.
