Underwater Earthquakes
Seismologists investigating
undersea earthquakes have
found that molten rock
lubricates faults. This
decreases the amount of
friction between sides of
the fault and decreases the
intensity of earthquakes.

Sun Darkens Electronics
Solar activity can wreak
havoc in communications
systems -- particularly
during coronal mass
ejections, when plumes of
electrically charged
particles hit earth's

Real-Time Quake Detection
Using ultrasound imaging,
seismologists can now
determine the epicenter and
magnitude of an earthquake
quake within 10 to 20
minutes, precisely imaging
which fault ruptured and
