EARTHQUAKE / The Long Road Back : QUAKE FACTS: Damage Report

Here are some facts and figures on the aftermath of last week’s magnitude 6.6 earthquake:

* DEATHS: 57 (state estimate)

* INJURIES: More than 7,671 people have been treated and released at hospitals; about 690 were admitted for care.

* AFTERSHOCKS: A magnitude 4.5 aftershock at 9:19 a.m. Thursday was centered two miles west of Granada Hills.

* DAMAGE: More than 25,148 buildings had been inspected. Officials have declared 5,812 buildings, including 15,581 dwelling units, at least partially unsafe.

* ARRESTS: Since the quake, the Los Angeles Police Department has taken 418 people into custody. On a typical day, there are about 530 arrests in the city.

* HOMELESS: Almost 1,869 remained housed in 176 Army tents at five San Fernando Valley parks. Thirty-one tents have been removed from Lanark Recreation Center.

* NATIONAL GUARD: Officials said some of the 1,000 National Guard troops mobilized to help in disaster relief efforts will begin moving out of the city, but some will be replaced by Guard troops from other areas. About 108 bilingual Guard troops are acting as translators.

* UTILITIES: The Southern California Gas Co. said an estimated 18,000 customers remained without gas service as of Thursday, largely because personnel cannot get into houses to check for possible leaks.

Approximately 150,000 homes, apartments and businesses lost gas service after the Jan. 17 Northridge earthquake and aftershocks.
