Quake Network
In the Global Seismographic
Network, 138 networked
stations can pick up quake
movement and send instant
information to computers
around the world. The
network has passed its first
real-world test: Sensors on

Predicting Major Weather Disasters
Disaster experts including
meteorologists and
seismologists have
identified the types of
catastrophic events the
United States is most likely
to face, quantifying the

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

New Disaster Warning Standard
Several federal agencies are
beginning to implement a
common, standardized system
for disseminating disaster
alerts, called the Common
Alert Protocol. The CAP is a
digital message format that

Geophysicists Discover Slippery Secret Of Weaker 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 ... > more -
Seismologists Find Large Earthquakes Can Trigger Smaller Ones In Unlikely Locations
Seismologists found that L-waves, slow-moving seismic surface waves, from larger earthquakes can trigger smaller earthquakes as they travel through the ground. Different from aftershocks because ... > more -
Engineers Design Nails To Better Resist Natural Disasters
Geometry and mathematical calculations were used to design a next-generation nail for building homes that are twice as resistant to high winds and nearly 50 percent more resistant to earthquake ... > more -
Seismologists Devise New Technique To Measure Pollution
Seismologists have tested a new way to measure the concentration of the dangerous groundwater contaminant Trichloroethylene (TCE). Ultrasonic waves called P-waves are sent through ground containing ... > more -
U.S.G.S., Caltech Seismologists Develop Online Tool to Predict Aftershocks
With a new online map, scientists can better forecast when and where aftershocks may happen. The maps calculate information based on historical earthquake patterns and known behavior of aftershocks. ... > more -
Improving Structural Engineering with Earthquake Simulator
To develop designs that can survive extreme seismic events, and to devise retrofit solutions for older homes, civil engineers who specialize in structural design test realistic models of homes in ... > more -
The Science Behind Wave Pools
Scientists gives us a sneak peek into the world of wave pools, and explain how these huge pools make constant waves. Waves are made by a huge compressor that feeds four gigantic air blowers. Then a ... > more -
Civil Engineers Develop Inexpensive System to Assess Damage after Natural Disasters
A new wireless system assesses injury in a structure after it is hit by a natural disaster such as a hurricane. When a building shakes, sensors records the frequency of the movement. This data is ... > more -
Geologists Create Map Of Threat Of Volcanic Eruptions Throughout The United States
Geologists combined research from around the country with Google Maps to show where volcanoes could erupt in the United States. The website is constantly updated to reflect the current status of ... > more -
Soil Scientists Restore Marshes To Protect Coastal Ecology
Soil scientists spread material dredged from shipping channels over shore areas to help rebuild marsh areas. Wetlands along the shore protect the land from storm surges, create habitat for wildlife, ... > more
