The capital rippled with aftershocks Wednesday, and President Hosni Mubarak was back from a shortened China trip to deal with the damage wrought by a deadly earthquake and provide for its victims.
Friendly countries immediately pledged more than $110 million in aid.More than 400 people were killed and 10 times that number injured in Monday's quake, which was reported to have destroyed or damaged 536 buildings.
A security official told Cairo Television that rescue workers stopped searching for survivors Tuesday everywhere but at a 14-story apartment building in the affluent suburb of Heliopolis. Dozens of people were believed to be buried under rubble there.
The search resumed Wednesday just after a dawn aftershock. Ezzeddin M. Ibrahim, a government earthquake expert, said seismographs south of Cairo registered the aftershock at 3.7 on the Richter scale. Ibrahim said another one, shortly before noon, measured 3.6.
"Aftershocks can go on for up to four weeks, gradually decreasing in intensity," he said.
On Tuesday, Mubarak told reporters the cost of repairs could run higher than $121 million and initial compensation payments for victims or families $3 million.
Arab and other countries pledged more that $110 million in aid.
