CU/ANWB Willy Bob, Antigua and Barbuda CU/BBGH Gun Hill, Barbados Earthquakes make gold veins in an instant : Nature News & Comment Shutterstock Veins of gold, such as this one trapped in quartz and granite, may deposit when the high-pressure water in which they were dissolved suddenly vaporises during an earthquake. Scientists have long known that veins of gold are formed by mineral deposition from hot fluids flowing through cracks deep in Earth’s crust. But a study published today in Nature Geoscience1 has found that the process can occur almost instantaneously — possibly within a few tenths of a second. The process takes place along 'fault jogs' — sideways zigzag cracks that connect the main fault lines in rock, says first author Dion Weatherley, a seismologist at the University of Queensland in Brisbane, Australia.
Space Weather Prediction with Cosmic Rays Introduction This Website is a gateway for space weather displays based upon cosmic ray data returned by the Spaceship Earth network of neutron monitors and from the worldwide muon detector network. The top of the site contains reduced versions of the plots that we consider most relevant for space weather prediction. Click any plot to obtain an enlarged version. As our space weather products are improved and optimized, these plots will change from time to time.
Pacific Northwest Seismic Network Seismicity at Mount Rainier is characterized by swarms of micro-earthquakes at shallow depth under the summit, larger and deeper events in the West Rainier Seismic Zone (WRSZ) just out side of the Park to the west (only partially shown on figures below) and very shallow seismic events due to glacier motion (not shown on figures below). Most earthquakes directly under the volcano occur at depths of 1-5 km below the surface; however, because of the difficulty of determining an accurate depth for very shallow events some of them have a fixed depth at the surface. Some of these shallow earthquakes occured in swarms lasting from a few hours to a few of days. The largest event in a swarm sometimes occurs in the middle of the swarm though many follow a standard main shock-after shock pattern. The largest events in the past 20 years were M=3.2 events in 2002 and 2004, although there was a M=4.5 earthquake in 2006 located about 10 km east of the summit.

Tiltmeter - Wikipedia A tiltmeter on Mauna Loa, used to predict eruptions by measuring very small changes in the profile of the mountain. A tiltmeter is a sensitive inclinometer designed to measure very small changes from the vertical level, either on the ground or in structures.[1] Tiltmeters are used extensively for monitoring volcanoes, the response of dams to filling, the small movements of potential landslides, the orientation and volume of hydraulic fractures, and the response of structures to various influences such as loading and foundation settlement. Tiltmeters may be purely mechanical or incorporate vibrating-wire or electrolytic sensors for electronic measurement. A sensitive instrument can detect changes of as little as one arc second.
Image: Black hole outburst in spiral galaxy M83 (Phys.org) -- NASA's Chandra X-ray Observatory has discovered an extraordinary outburst by a black hole in the spiral galaxy M83 (Messier 83), located about 15 million light years from Earth. Using Chandra, astronomers found a new ultraluminous X-ray source, or ULX. These objects give off more X-rays than most normal binary systems in which a companion star is in orbit around a neutron star or black hole.
