Monitoring Volcanic Craters with Infrasound “Music”
Volcanic craters act as giant horns that emit intense low-frequency sounds. Changes in this infrasound may be used to track rising lava lakes and identify signals of future eruptions.
Ordinary Security Cameras Could Keep an Eye on Rainfall
A new opportunistic sensing strategy could use existing closed-circuit television networks to accurately capture rainfall intensity, despite low-cost equipment and visually complex scenes.
Gauging in the Rain
Measuring how much water falls from the sky is more complicated than it seems. To improve measurements, researchers are looking at umbrellas, hydrophones, and gamma ray detectors.
Underground Robots: How Robotics Is Changing the Mining Industry
From exploring flooded sites to providing alerts, use of robotics aims to “increase the arsenal of tools that can help miners work more safely and efficiently.”
X-Ray Computed Tomography Detects Resolution Scale Gold Grains
A method combining partial-volume and blurring effects can be used to measure small features in computed tomography data volumes.
First Possible Marsquake Detected
First earthquakes, then moonquakes, now marsquakes: a robotic lander comes through with the first detection of seismic activity on Mars.
A New Way of Visualizing Iceland’s Crustal Deformation
A novel method of calculating strain rates from GPS data shows the South Iceland Seismic Zone is experiencing rapid deformation, including inflation near the island’s most active volcano.
Measuring Explosive Events on Earth from the Ionosphere
Natural and manmade explosive events occurring on or below the Earth’s surface can be measured remotely in different ways and different places from the ionosphere.
The Accidental Particle Accelerator Orbiting Mars
The radar aboard the Mars Express spacecraft can generate ion beams arcing through space above the planet, which could lead to a new way of studying the plasma surrounding it.
