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
... > full story
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

Volcano Warning!
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 individual volcanoes, and

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 -
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 -
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 -
Computer Technology Gets The Word Out Faster During A Disaster
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 can be ... > 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 -
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 -
Geographers Map Likeliest Places For Big Fires
Foresters and geographers have mapped the locations in the Santa Monica mountains where the most destructive fires are likely to start. To make their map, they combined data about where fires were ... > 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 -
Geoscientists Investigate Rare Carbon Formation
Carbonados, black carbon formations that resemble diamonds, have been show to have a chemical spectrum that indicates they originated before the formation of the Earth; their high hydrogen content ... > more -
Using Radar, Meteorologists See Increase in Hurricane-Made Tornadoes
Tornadoes can form when hurricanes make landfall, as their winds at ground level slow down, while the winds near the top keep their momentum. Data from 2004 show this tendency seems to have ... > more
