Mapping areas at risk from liquefaction

A team of researchers has joined forces to investigate and find solutions to tackle one of the most devastating forms of seismic phenomena - liquefaction. Liquefaction occurs in loosely-compacted sandy soils which are fully saturated with water. Seismic vibrations...

Earth’s vibrational "hum" - frequencies at which our planet naturally vibrates measured

Scientists have long known earthquakes can cause the Earth to vibrate for extended periods of time. However, in 1998 a research team found the Earth also constantly generates a low-frequency vibrational signal in the absence of earthquakes. Since then, seismologists...

Unearthing the underground effects of earthquakes and volcanoes

Japanese researchers find predictive potential in underground changes associated with 2016 Kumamoto earthquake and subsequent volcanic eruptions. Most of what we know about earthquakes and volcanoes is based on what we can observe at the Earth's surface....

Parkfield segment of San Andreas fault can host large earthquakes

Although magnitude 6 earthquakes occur about every 25 years along the Parkfield Segment of the San Andreas Fault, geophysical data suggest that the seismic slip induced by those magnitude 6 earthquakes alone does not match the long-term slip rates on this part of...
