BIGQUAKE
Sends a message whenever an earthquake is reviewed by the duty geophysicist that has a magnitude of 5.5 or greater anywhere in the world or a magnitude of 4.5 or greater within the 50 US states, excluding the Aleutian Islands of Alaska. The speed of review is somewhat variable, but in most cases a magnitude 6.5 or greater event anywhere in the world or a magnitude 4.5 or greater event within the contiguous US is reviewed within a few hours of its occurrence. Other events meeting the bigquake criteria are reviewed within one or two days.
The subject line of each bigquake message contains key earthquake parameters so that pagers and cell phones may be used to receive these messages.
