Earthquake's trampoline effect
During earthquakes the ground not only shakes from side to side, but also bounces up and down; this has important implications for designing quake-proof structures

Using laptops to detect earthquakes
Laptops have a small accelerometer chip built into them in order to protect the delicate moving parts of the hard disk from sudden jolts; same chip is a pretty good earthquake sensor, too

Hurricane proofing Houston's power
In the aftermath of Hurricane Ike, residents, politicians, and utility officials say it is time to consider burying electric lines underground in order to hurricane-proof Houston

Invisibility cloak as a protection against tsunamis
Rather than fortifying sea platforms and coastal towns to withstand tsunamis, it may be possible to use invisibility cloaks to make off-shore platforms, islands, and even cities “invisible” to waves

New Orleans coped well with Gustav
The planning and execution of hurricane emergency measure was far superior to what happened during Katrina, even if the challenge was not as demanding; analysts worry that with Gustav failing to live up to expectations of devastation, we may witness “evacuation fatigue” next time

Major flooding risk could span decades after Chinese earthquake
Earthquake-induced landslides cause rocks and sediment to be dumped in the river valleys, and this material then moves downstream to settle on river beds; this means that river and lakes become shallower, pausing much greater risks of flooding for decades to come
