A warning system for tsunamis

Seismologists have created a new algorithm that could one day help give coastal cities early warning of incoming tsunamis. Right now, tsunami warning systems rely...

Giant tsunamis washed over ancient Mars

Some 3.4 billion years ago, giant meteoroids slammed into a frigid ocean covering Mars's northern hemisphere. The impacts kicked up enormous waves that raced...

Ancient tsunami evidence on Mars reveals life potential

‘Slow’ NZ seabed quake sheds light on tsunami-earthquake mechanism

Slow earthquakes such as slow slips are drawing the attention of researchers due to their potential connection to tsunami earthquakes. An international team of seismologists...

Preparations for a US west coast tsunami look to the past...

After the 2011 Tohoku earthquake and devastating tsunami in Japan, states such as California, Oregon, Washington and Alaska are looking to both the past...

New theory of deep-ocean sound waves may aid tsunami detection

Acoustic-gravity waves are very long sound waves that cut through the deep ocean at the speed of sound. These lightning-quick currents can sweep up...

Better, faster tsunami warnings possible with GPS

Existing GPS instruments at monitoring stations worldwide could be used to increase the speed and accuracy of tsunami warnings, according to new study accepted...
