Preparedness

• The Indiana Department of Homeland Security (IDHS) makes several earthquake preparation recommendations for southern Indiana residents. For instance, an earthquake may topple furniture and large objects, so place heavy objects on lower shelves and be sure that free-standing walls and chimneys are fastened in place. A water heater, for example, can be bolted to the studs of a wall. Finally, earthquakes may damage a home's structure, so be certain someone in the household understands how to shut off utilities like gas, electricity and water.
  
  

Inside Safety

• IDHS recommends that during an earthquake, which can last from a few seconds to to several minutes, people should crawl under a large piece of furniture. A firm grip on the furniture during the earthquake is also important, because the piece may move. If a suitable piece of furniture is unavailable, standing inside a doorway can also provide protection. Aftershocks may prove dangerous, so remain cautious immediately after an earthquake.
  
  

Outside Safety

• Outside, maintain a safe distance from tree limbs, tall buildings, power lines and similar objects, which are falling hazards. For those inside a vehicle during an earthquake, drive slowly or park and remain as far as possible from tall objects. Do not enter a building unless it appears to be structurally unaffected by the earthquake.
  
  

After an Earthquake

• Safety after a serious earthquake involves taking account of the area and taking action if possible. First, check for injuries and offer aid to others who may be hurt. Seek out a radio or television to determine whether emergency officers have broadcast general instructions. Check buildings for structural damage and do not re-enter if any is suspected. Extinguish small fires. For those in a building that uses gas, listen for a hissing or similar noise. If detected, shut off the main gas supply and exit the building.
  
  

Damage

• The 1968 magnitude 5.3 earthquake centered near Dale, Illinois, remains one of the most powerful recorded events to affect modern Indiana. Nevertheless, most damage remained limited to damaged or destroyed chimneys and spilled shelves at grocery stores.
