From EARTH Magazine, 09/17/2015 -- Americans are reminded in September to be prepared for natural hazards during "National Preparedness Month." A major goal of preparedness is to provide early warnings for earthquakes. Earthquake early warning (EEW) is exactly what it says: It is an early warning that shaking is coming and it can typically give a few seconds to a few minutes, at most, of warning. The warnings can be sent off just after an earthquake occurs on a fault, but before the damaging secondary waves are felt. It is not earthquake prediction.

From EARTH Magazine, 08/03/2015 -- It now appears that, of the many moons of Jupiter and Saturn, two of them may have oceans beneath their icy exteriors. Scientists studying Jupiter's moon Ganymede - the largest moon in the solar system and the only one with its own magnetic field, which frequently sparks aurorae - used the Hubble space telescope to detect ultraviolet light emitted by the aurorae, which were less active than expected, given the moon's magnetic field.
From EARTH Magazine, 07/28/2015 -- The United States' Icebreaker Fleet - operated by the U.S. Coast Guard - consists of just two ships that are used for everything from search and rescue to national security operations to scientific research. In our August cover story, EARTH Magazine examines the various roles icebreakers play, especially in Arctic research, and how insufficient funding is affecting the icebreakers' roles.
From EARTH Magazine, 06/29/2015 -- Analyzing thousands of records, researchers have reinforced the claim that for marine life, bigger has been better for the last 542 million years. The study examined Cope's rule - the idea, named for paleontologist Edward Drinker Cope, that species evolve to larger sizes over time.
From EARTH Magazine, 06/24/2015 -- Humans depend on copper for everything from electrical wiring to water pipes. To meet demand, the metal has been largely mined from Porphyry Copper Deposits (PCDs). For decades, scientists generally agreed upon the geological processes behind PCD formation; now EARTH Magazine examines two new studies that suggest alternatives to these long-held understandings.
From EARTH Magazine, 06/16/2015 -- From the tiny microcosms of atomic theory and futuristic colonies on Mars to dinosaurs walking the Earth, science illustrators translate scientific findings and theories into something lifelike, accurate and aesthetically pleasing. The July cover story from EARTH Magazine, "Science Illustrators: Making the Invisible Visible," takes readers on a behind-the-scenes of how illustrators transform a scientific concept into an informed work of art.
From EARTH magazine, 05/27/15 -- As this summer's blockbuster movie season gets underway, EARTH Magazine asks an important question: In movies, "are geologists portrayed as heroes or villains?" The topic of how geologists are portrayed in film has been oft-debated around a campfire, or over a frosty beverage at the end of a day of fieldwork, but now four scientists bring some serious analysis to the subject in the June issue feature, "Rock Stars - Geologists on the Silver Screen."
From EARTH Magazine, 05/20/15 -- In the years following the 1986 Chernobyl nuclear disaster, forest fires billowed plumes of contaminated smoke, carrying radioactive particles throughout Europe on the wind. Now, researchers fear that a shift to a hotter, drier climate in Eastern Europe could increase the frequency of these fires.
