EARTH Magazine: Vital Seconds - The Journey Toward Earthquake Early Warning for All

EARTH Magazine

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.

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.
