T - Labs also provided phones that Kong tested on shake tables at UC Berkeley, which realistically simulate the vibrations
from large quakes such as the 1989 Loma Prieta earthquake south of San Francisco.
For locations far
from a large quake's origin, waiting for clear signs of risk before sending an alert may mean waiting too long for people to be able to take protective action.
Not exact matches
So far they have mapped the natural geologic stresses throughout Oklahoma and Texas — the states with the
largest populations at risk
from human - induced
quakes — and have discovered that only a fraction of faults hold the potential to slip in the presence of moderate pressure increases.
But the release of stress
from this latest
quake does not relieve the risk of an even
larger earthquake expected further north.
The mapped surface rupture was unusually
large for a moderate
quake, extending nearly eight miles
from Cuttings Wharf in the south to just west of Alston Park in the north.
In a recent paper in Bulletin of the Seismological Society of America, geologist Colin Amos of Western Washington University and colleagues found that an 1872
quake hundreds of miles
from the SAF was among the
largest in California history, reaching 7.7 to 7.9 on the Richter scale.
Science answers:
From past
quakes, an estimate of the likely
largest aftershock can be made.
The Japanese system, which began operation on October 1, has already provided warnings
from two
large quakes.
The
largest quake detected occurred on April 16 in Ecuador: a 7.8 magnitude
quake that triggered two phones, 170 and 200 kilometers
from the epicenter.
The changes raised the estimated likelihood of a magnitude - 8 or
larger quake in California over the next 30 years
from 4.7 % to 7 %.

Images
from the European Space Agency show that icebergs, some
larger than Manhattan island, broke away
from Antarctica just a few days after the
quake.
