"Earthquake aftermath: survival, rescue, recovery in California"
- The aftermath of a major earthquake in California could lead to severe consequences, including aftershocks, structural instability of buildings, and a shortage of shelter.
- Estimates suggest that 750 people in LA could be trapped in ruined buildings, 270,000 could be homeless, and 50,000 may require emergency care that might not reach them in time.
- Search and rescue operations could last for 19 days after the quake, with potential fatalities from various causes like falling debris, lack of treatment, and contaminated water.
- Restoring normalcy post-earthquake could take up to a year, with potential economic collapse in LA and a slow recovery process for the region.
- Survival tips for earthquakes include not running outdoors, taking cover under sturdy objects, and holding on during the shaking.
- Additional survival strategies involve keeping bottled water, avoiding screaming to conserve oxygen, and using cell phones for communication as a crucial lifeline during the disaster.
