Latest Earthquake Stories
A previously unknown channel of slow-moving seismic waves in the Earth’s mantle has been discovered by a team of scientists from the University of California, Berkeley and the University of Maryland.
As National Preparedness Month begins, it may be a good time to reflect on the threats we face around us, including damaging hurricanes, devastating wildfires, extreme heat waves and severe drought, among others.
While the waves from a tsunami can be extremely destructive, acoustic waves could help warn of the impending danger.
Real time observation of shear waves on the Earth's surface, first direct observation of subducting continental crust during the collision of two continents
WorkSafe Technologies of Northern California understands Cal State's recent decision to demolish Warren Hall after being declared the most seismically unsafe structure in the university system.
Since records began in 1776, the people of Youngstown, Ohio had never experienced an earthquake.
In 2006 the island of Java, Indonesia was struck by a devastating earthquake followed by the onset of a mud eruption to the east, flooding villages over several square kilometers and that continues to erupt today.
Scientists often detect a series of small earthquakes just before a volcanic eruption and a new study published in the Journal of Volcanology and Geothermal Research has shown that these tremors can happen in such a rapid succession – that they create sound vibrations that rise in pitch until the volcano erupts.
Two studies published in the journal Science have both found human geologic activities could be causing nearby seismic activity.
The Pacific Ring of Fire, or Ring of Fire for short, is an area where a large number of earthquakes and volcanic eruptions occur in the basin of the Pacific Ocean. In a 25,000 mile horseshoe shape, it’s associated with an almost continuous series of oceanic trenches, volcanic belts, volcanic arcs and/or plate movement. The Ring of Fire contains 452 volcanoes and is home to over 75 percent of the world’s active and dormant volcanoes. It’s sometimes called the circum-Pacific belt or the...
The Richter scale assigns a single number to quantify the amount of seismic energy released by an earthquake. The scale uses a base-10 logarithm by calculating the logarithm of the combined horizontal amplitude of the largest displacement from zero on a particular type of seismometer. A earthquake measuring 5.0 on the Richter scale has a shaking amplitude 10 times larger than one that measures 4.0. The moment magnitude, calibrated to give generally similar value for medium-sized...
