Before the explosion - volcano's warning tremors explained
— 24 Feb 2011 19:20 | Geology and palaeontologyNo matter their size or shape, explosive volcanoes produce tremors at similar frequencies for minutes, days or weeks before they erupt. In the Feb. 24 issue of the journal Nature, researchers…
Oscillating 'plug' of magma causes tremors that forecast volcanic eruptions: UBC research
— 24 Feb 2011 18:47 | Geology and palaeontologyUniversity of British Columbia geophysicists are offering a new explanation for seismic tremors accompanying volcanic eruptions that could advance forecasting of explosive eruptions…
Sun and moon trigger deep tremors on San Andreas Fault
— 24 Dec 2009 13:02 | Geology and palaeontologyThe faint tug of the sun and moon on the San Andreas Fault stimulates tremors deep underground, suggesting that the rock 15 miles below is lubricated with highly pressurised water that…
Tremors between slip events: More evidence of great quake danger to Seattle
— 16 Dec 2009 11:16 | Geology and palaeontologyFor most of a decade, scientists have documented unfelt and slow-moving seismic events, called episodic tremor and slip, showing up in regular cycles under the Olympic Peninsula of…
Tremors on southern San Andreas Fault may mean increased earthquake risk
— 10 Jul 2009 13:59 | Geology and palaeontologyIncreases in mysterious underground tremors observed in several active earthquake fault zones around the world could signal a build-up of stress at locked segments of the faults and…
Study links seismic slip and tremor, with implications for subduction zone
— 29 Jan 2009 19:00 | Geology and palaeontologyIn the last decade, scientists have recorded regular episodes of tectonic plates slowly, quietly slipping past each other in western Washington and British Columbia over periods of…
