I will just put some things I learned from the christchurch earthquake if anyone is interested.
MY brother was actually there on the day it happened for a medical conference. So that was God's providence.
They had some warning previously when an earthquake happened at night but nobody got hurt as all were safe and sleeping in their beds. But this one that killed 185 people on 22 february 2011 at 12:51 pm was the big one. It measured 6.3 on the richter scale.
Aftershocks happened a lot after. But christchurch was devastated. Entire buildings collapsed, esp the CTV tower and the beloved christchurch cathedral. Since chch was built on old swamp land there was a lot of liquefaction..the ground bubbled up.
Most people gathered in parks where tents were set up..hagley park was the main gathering place. Flights of course could not get out. People stuck in buildings and rubble had to be rescued, some had to have limbs amputated.
Mobile phone coverage was cut off...but landlines still worked if they were analogue.
Sewerage backed up so people were using buckets.
Of course insurance claims went on for a long time and many people lost their homes and many could not move as they had nowhere else to stay or go.
Other towns in nz rallied to help and send funds for emergency services and care in chch. Thank God for the sallies, st john ambulance, student cadets, nz army...and ordinary everyday people who might have been strangers before the earthquake but helped each other to survive. Impromptu church services were held in the open air. People buried their dead.
People prayed.
