Laser tech is set to measure earthquake damage to buildings

A diagram illustrating how the Discrete Diode Position Sensor works

How safe would you feel, going back into a multi-story building that had just been through an earthquake? A new sensor system could allay your fears, as it optically measures how much a building has swayed, and thus how damaged it may be.

Alphabet’s balloons broadcast LTE two days after Peruvian quake

When a magnitude 8.0 earthquake hit Peru Sunday, the Alphabet spinoff Loon was quick to respond. Within 48 hours, Loon delivered its internet-relaying balloons and began providing LTE coverage to users below. While more balloons are on the way, Loon...

Massive mountain range found in the Earth’s mantle

A diagram of the Earth's layers, including the transition zone – the bottom boundary of which ...

The surface of the Earth is a bumpy place, with terrain made up of smooth ocean floors to jagged mountain peaks and everything in between. But according to a new study, that's nothing compared to the landscapes found deep within the planet. Using data from one of the biggest earthquakes on record, geophysicists have now found massive mountain ranges hundreds of kilometers beneath our feet.

Undersea seismographs pop to the surface to transmit data

One of the MERMAID seismic floats reaches the surface

Although traditional seismographs are essential for warning of earthquakes, they can be difficult to access when placed on the sea floor. Well, that's where the MERMAID underwater seismic floats are designed to come in, and they've recently been successfully tested in the Galápagos.

Earthquake vibrations suggest Earth’s inner core is solid but squishy

By measuring seismic waves passing through the center of the Earth, researchers have concluded that the ...

With more than 5,000 km (3,000 mi) of rock between us and the Earth's core, it's hard to get a clear look at what's going on down there. It's long been thought that the inner core is a solid ball of iron, but direct evidence is hard to come by. Now, researchers from the Australian National University (ANU) have detected a type of seismic wave passing through the core that only propagates through solid objects.

The ancient earthquake detector that puzzled modern historians

Modern seismographs are extremely sensitive pieces of equipment. By recording the slightest movements of laser light or magnets, these devices can detect the smallest of rumbles even when we can't sense them. There are networks of thousands upon thou...
