Power was mostly restored to New Zealand's quake-damaged city of Christchurch on Tuesday after strong aftershocks brought down more buildings and killed a nursing home resident.
The latest quakes _ the strongest of which was 6.0 in magnitude _ left tens of thousands without electricity on a winter night when temperatures approached freezing. By afternoon, around 7,000 households were still without power. The power company Orion said it was providing generators to fill some of the gap.
Water supplies were also compromised, and Mayor Bob Parker was encouraging people to boil their water.
More than 40 people suffered mostly minor injuries in Monday's earthquakes. But the Canterbury District Health Board confirmed the death of an elderly resident of a nursing home who reportedly fell and hit his head.
Thousands of aftershocks have followed the February 6.3-magnitude quake that killed 181 people. That tremor and its aftershocks have been very shallow and near the city, making them very destructive.
Monday's quakes sent bricks crashing down in the cordoned-off city center, where only workers have tread since it was devastated in February. About 50 buildings were destroyed and more masonry fell from the city's already badly damaged Christchurch Cathedral.
On Tuesday, Parker warned residents not to enter houses that have been condemned.
"We can avoid calamities for our people even if we can't our buildings," he said.
