The month of November 2016 was meant to be remembered for the super moon – a beautiful big bright full moon at its perigree – the closest point to earth since 1948.
Instead, at NZ Daylight time on Monday, 14th November, 2016, at 2.56 minutes after midnight, an earthquake struck. Universal Time, it was 13th November, 2016, 11:02:56.
The earthquake was a 7.8 magnitude earthquake, located 15 km north east of Culverden, and we felt it here in Glenside.
The following day, Tuesday, 15th November, the rains fell. There was flooding, winds, erosion, falling trees and high tides across the Wellington Region. In Glenside, we had already experienced heavy rainfall over the weekend, which had caused small slips along Middleton Road and a few trees to fall into the Porirua Stream. This new dump of rain was a bit of a worry.
Tucked away in the Glenside Valley, we texted, emailed, and contacted each other to make sure everyone was safe.
We kept a watchful eye on the ever rising height of the stream which flows through our valley down to Tawa and the Porirua Harbour. We reported back to our local City Councillor's and our Regional flood management team.
Our Glenside Progressive Assn. network got active.
- The Community Patrollers, Jaqs and Hayden patrolled the roads, putting out warning cones and directing traffic and keeping police informed.
- Our President, Claire, took photographs of the debris arrestor emailed them to Regional Council staff and Councillors.
- Barry, our Revegetation project lead, took photographs of the Stebbings Stream erosion and emailed them to WCC Council staff.
- Andrea, our Facebook manager, worked hard to get our shared information online and available for residents to be kept informed.
Here's some photographs of the 'quake, and rain impact in Glenside and at Willowbank.

Bridge on intersection of Middleton and Rowell's Road in Glenside. Tuesday, 15th November 2016, 6:34am. Our Facebook page advised that the stream was running at slightly higher than usual conditions but nothing untoward, and there was some surface flooding on Middleton Road northbound through the Glenside gorge area due to blocked drains.
The debris arrestor, Tuesday, 15th November 2016, 6:37am. Ten hours later it was packed with logs and branches and fallen trees. There were also household items, most likely dumped down the streambanks illegally, and picked up by rising flood waters.
