California’s new earthquake early warning
cellphone app issued its first public alert when a
modest tremor occurred this week in a rural area
of the state, a newspaper reported.
MyShake app project manager Jennifer Strauss
said more than 40 people received the warning
when a 4.3 magnitude quake struck Tuesday
morning in mountains between the central
coast and the San Joaquin Valley, the Los
Angeles Times said.
The MyShake app was developed by the
University of California, Berkeley, and released
in October.
It is designed to quickly take data from seismic
sensors and send warnings to potentially
affected areas if a quake of magnitude 4.5 or
greater occurs and if the projected shaking at a
particular location is at a certain level of intensity.
