Waveforms from the HVO Seismic Network What's New The latest version of Volcweb was launched December 20, 2013. Based on feedback from our users (you), we have made the following adjustments: Auto-refresh: The webpage now automatically refreshes when the page has been inactive for 10 minutes. If you move your mouse on the webpage, the timer restarts. Earthquake list: The earthquake list has been moved to a tab behind the control panel on the left. The dots presented in this map represent earthquake location calculated by the Hawaiian Volcano Observatory and its partners. Earthquakes are routinely reviewed by a seismic data analyst and updates posted to this web site. When an earthquake occurs, seismic waves are created, which propagate away from the focus or hypocenter. The magnitude of an event is determined from the strength of the seismic waves detected at each station.
Bloodsuckers Spreading a New Deadly Virus in the U.S. Photo credit: bigstock.com Springtime is here friends and you know what that means: sunshine, walks outdoors, camping trips, field trips for the kids and those ugly, bloodsucking, disease infested ticks. As if ticks on their own are not disgusting enough, the fact that they harbor and spread disease only makes them more repugnant. Named after the county in Kansas where it was first discovered, the Bourbon virus was isolated for the first time by the CDC (Centers for Disease Control and Prevention) after the death of a 50 year old man in spring of 2014. The infected male was working on his property and was the victim of multiple tick bites. While the victim was hospitalized, doctors there tested him for known infectious diseases, but all tests returned negative. This information was published in the CDC’s own journal “Infectious Diseases.” Continue to Page 2 Now there are several types of thogotoviruses that are known from around the globe, however, this particular strain is new.

The Volcanism Blog The Extinction Protocol | Geologic and Earthchange News events The Global Earthquake Explorer General Info GEE is an education and outreach tool for seismology that aims to make it easy for non-seismologists to retrieve, display and analyze seismic data. It is intended for use in a classroom setting as a supplement to textbook material, which often lacks real world connections. Novices . . . can use GEE to explore earthquakes they've seen in the headlines. GEE is comprised of configurable learning "modules" that can be used to convey specific seismological concepts such as wave properties, the structure of the earth, and the differences between P and S waves. Technical Info GEE makes use of the Fissures/DHI for data delivery.
Chemicals In Our Waters Are Affecting Humans And Aquatic Life In Unanticipated Ways -- ScienceDaily American and Canadian scientists are finding that out of sight, out of mind can no longer be the approach we take to the chemicals in our waters. Substances that we use everyday are turning up in our lakes, rivers and ocean, where they can impact aquatic life and possibly ourselves. Now these contaminants are affecting aquatic environments and may be coming back to haunt us in unanticipated ways. Derek Muir of Environment Canada and colleagues have determined that of the 30,000 or so chemicals used commercially in the United States and Canada, about 400 resist breaking down in the environment and can accumulate in fish and wildlife. John Incardona and Nathaniel Scholz at National Oceanic and Atmospheric Administration's Northwest Fisheries Science Center and the West Coast Center for Oceans and Human Health found that polycyclic aromatic hydrocarbons (PAHs) left in Pacific waters after the Exxon Valdez oil spill caused heart defects in herring and pink salmon embryos.

More Evidence that the Moon Contributes to Earthquakes An almost-full, half-pie, waxing moon hanging lopsided in the night sky has long been a symbol of things to come. Now scientists have a new symbolism for the lunar phase we call first quarter: a looming risk of earthquakes. The moon is (mostly) responsible for Earth’s tides, which are strongest when the sun and moon are aligned, during a full moon or a new moon. Still, scientists have wondered for years whether the moon might play a role in earthquakes, which are essentially movements of the Earth’s crust atop its mantle. Studying data from the past two decades, Satoshi Ide and colleagues from the University of Tokyo measured the timing of high tides and reconstructed the amplitude of the moon’s pull at those times, focusing on the two weeks prior to large earthquakes. Ide and colleagues noticed the Dec. 26, 2004 Sumatran earthquake, most notable for its horrendous, deadly tsunami, occurred near the time of full moon and spring tide.
