LATIMES.COM WST THURSDAY, MARCH 5, 2020A


has been working on the re-
port for five years. “We have
a seismic source here, run-
ning through downtown.”
Particularly troubling is
that for many decades the
San Diego area was built to
lower seismic standards
than the ones applied to L.A.
or San Francisco, based on
the belief that San Diego had
a lower seismic risk.
It was only after the dis-
covery of the Rose Canyon
fault’s activity that the min-
imum building codes for this
region were raised to Seis-
mic Zone 4, the highest level
and the same as that of Los
Angeles and San Francisco,
said Heidi Tremayne, execu-
tive director of the Earth-
quake Engineering Re-
search Institute, a nonprofit
based in Oakland.
“Many older, more seis-
mically vulnerable buildings
constructed before modern
seismic design provisions
were in place, including sev-
eral key City of San Diego fa-
cilities, may be severely
damaged with multiple old-
er buildings potentially suf-
fering partial to total col-
lapse,” the report said. It did
not specify which buildings.
There could be many
deaths, as the San Diego re-
gion has relatively weak lo-
cal laws requiring retrofits of
vulnerable buildings com-
pared with cities like Los An-
geles and Santa Monica. The
San Diego region is esti-
mated to have thousands of
apartment buildings with
flimsy ground floors, hun-
dreds of potentially brittle
concrete buildings that can
be particularly deadly if they
collapse, and scores of pos-
sibly vulnerable steel-frame
office and hotel buildings.
None of the buildings de-
scribed above are required
to be retrofitted in the city.
And for another particularly
deadly class of buildings, old
brick buildings, San Diego
required only limited partial
retrofits, the report says.
The authors expressed
great concern that the col-
lapse or damage of these old
brick buildings — which
have been ordered retrofit-
ted or demolished in other
cities like L.A. — would dra-
matically worsen emergency


response. Several hundred
of them are believed to re-
main in places like down-
town San Diego, National
City, Chula Vista, El Cajon,
Solana Beach, Encinitas,
Oceanside and unincorpo-
rated areas of the county.
Many of San Diego’s civic
institutions may end up be-
ing crippled, including po-
lice and fire stations and city
offices, as first responders
are called to perhaps hun-
dreds of fires. The research-
ers estimate that nearly half
of county schools and hospi-
tals could be running at par-
tial capacity for days.
Military facilities around
San Diego Bay would suffer
from severe ground shaking
and liquefaction. And more
than 100,000 residential
structures could be dam-
aged — many of them apart-
ments — worsening the af-
fordable housing crisis.
And with land on the
western side of the fault
lurching to the northwest
relative to the eastern side,
many pipelines, cables,
bridges and railroads could
be severed or otherwise dis-

rupted. Water, wastewater
and gas lines serving areas
west of the fault, from La
Jolla through Coronado,
could be cut off for months
after the quake. Coronado
firefighters could find them-
selves without functioning
water pumps to fight fires.
San Diego International
Airport could find itself
hamstrung as land under-
neath it acts like quicksand
when shaken, damaging the
runway, taxiways and build-
ings. A western section of the
fault passes directly under
the runway, and a quake
would render it temporarily
inoperative.
Gas line breaks and a loss
of water pressure would
make firefighting even more
difficult.
And although the Co-
ronado Bridge has been
retrofitted to withstand col-
lapse, experts said they ex-
pect land on one side of the
fault to lurch two to three
feet from the other side.
Damage could render the
bridge unusable for weeks,
months or possibly years.
For decades, there had

been no scientific work done
demonstrating the Rose
Canyon fault was active.
Then, in 1985, the first hint
appeared during an excava-
tion at Broadway and 14th
Street, where a section of the
active fault was discovered,
said Tom Rockwell, profes-
sor of geology at San Diego
State.
The big discovery came
in 1990, when trenches were
dug across the fault in Rose
Canyon. It showed the land
on the western side of the
fault had lurched to the
northwest 30 feet over vari-
ous earthquakes in the last
8,000 years, convincing evi-
dence that the fault was
alive, Rockwell said.
Today, it’s believed the
Rose Canyon fault ruptures
in a big earthquake of some-
thing approaching a magni-
tude 7 about every 700 years
— give or take 400 years or
so. The last such major
quake is believed to have
happened between 1700 and
1750, Rockwell said, before
the Spanish founded their
first California mission in
San Diego in 1769.

Between those big
quakes, quakes in the range
of magnitude 6 can strike.
Such a quake ruptured on
the fault right through Old
Town in 1862, causing what
the Los Angeles Star de-
clared the “Day of Terror” in
San Diego, Rockwell said.
Today, it’s known that
the Rose Canyon fault is ac-
tually the southern contin-
uation of the Newport-Ingle-
wood fault, which caused
Southern California’s dead-
liest earthquake on record,
the magnitude 6.4 Long
Beach earthquake of 1933
that killed 120 people.
Without a major change
in San Diego’s psyche about
earthquakes, the city could
end up facing the fate of the
city of Christchurch, New
Zealand.
Many people in
Christchurch also thought
of themselves as relatively
safe from earthquakes, so
when a magnitude 6.3 quake
ruptured under the city in
2011, the damage was cata-
strophic: The central busi-
ness district downtown was
left in ruins and 185 people

died, mostly from the col-
lapse of unretrofitted brick
buildings and two brittle
concrete buildings.
“Having spent a decade
working down there and
knowing how people felt
about the risk before and
now, this is still such a shock
to them,” said Laurie John-
son, president of the re-
search institute and an ur-
ban planner.
San Diego can avoid this
future if there’s a concerted
regional effort to retrofit vul-
nerable buildings and infra-
structure before such a
quake hits. The authors rec-
ommend a committee of gov-
ernment officials, earth-
quake experts, utilities and
others to identify county
seismic hazards and suggest
actions.
“Without that advanced
mitigation work, we are wor-
ried it could jeopardize the
economic vibrancy of the re-
gion,” Tremayne said.
Strengthening the region
against quakes is part of
the bargain of living in San
Diego.
“We owe a lot of the
beauty of San Diego to the
Rose Canyon fault,” from
the fault pushing up Mt. Sol-
edad by La Jolla to the cre-
ation of the bays of San Di-
ego, Rockwell said, enabling
it to be the principal home
port of the Navy’s Pacific
Fleet.
“If we did not have the
Rose Canyon fault, then we
would look like Oceanside.
It’d be a long, linear coast-
line with not much going
on,” Rockwell said. “Because
the fault line comes on shore
in San Diego, it produces the
topography that makes San
Diego unique.”
At a panel discussion af-
ter the release of the report,
Ali Fattah, senior research
engineer for the city of San
Diego, said there would be
challenges in strengthening
vulnerable buildings.
“It’s easy to get rules out
there,” Fattah said, but the
city doesn’t have the re-
sources right now to create
an inventory of vulnerable
buildings. He also suspects
residents will be opposed to
the city imposing strength-
ening requirements on old
buildings.

San Diego faces major quake threat


SAN DIEGOcould see 120,000 buildings damaged and over $40 billion in losses from a quake, a study says.

WASHINGTON — The
Supreme Court heard its
first abortion case with
President Trump’s two new
conservative appointees on
Wednesday, but the conser-
vative justices sounded as
though they might move
cautiously rather than issue
a broad ruling on the issue.
The justices focused
their questions on how spe-
cifically a Louisiana law re-
quiring doctors who per-
form abortions to have hos-
pital admitting privileges
would affect women and
clinics that perform the pro-
cedure.
Four years ago, the court
by a 5-3 vote struck down a
nearly identical law in Texas.
“This case is about this
court’s respect for prece-
dent,” Julie Rikelman, a law-
yer for the Center for Repro-
ductive Rights, told the jus-
tices. If the state’s law took
effect, “it would leave Louisi-
ana with just one clinic and
one doctor providing abor-
tions,” she said. And it
“would do nothing for wom-
en’s health.”
But Chief Justice John G.
Roberts Jr. and Justice
Brett M. Kavanaugh, who
likely hold the deciding
votes, suggested that prece-
dent alone would not deter-
mine the outcome.
Roberts said the facts of
each case may differ, and
therefore “the results would
be different in different
states.”
Even though the high
court had struck down the
similar Texas law as uncon-
stitutional, the U.S. 5th Cir-
cuit Court of Appeals in New
Orleans upheld the Louisi-
ana law on the grounds
that the admitting-privi-
leges rule would have less ef-
fect in Louisiana.
Kavanaugh agreed with
Roberts, saying the issue
was not simply whether ad-
mitting privileges by them-
selves are improper, but
whether they impose an un-
due burden.
If, for example, all doc-
tors in a state obtained ad-
mitting privileges, would a
requirement on abortion


providers still be unconsti-
tutional, he asked. “Could
you say that the law still im-
poses an undue burden,
even if there is no effect?”
Rikelman conceded that
would be a harder case to
win. She stressed, however,
the admitting-privileges
rule “has no medical ben-
efits whatsoever.”
It extends to doctors who
do no surgery but simply dis-
pense pills that induce an
abortion, she said. And its
impact in Louisiana “would
be severe. It would leave only
one physician to serve 10,
people per year in the entire
state.”
Roberts also pressed
Elizabeth Murrill, Louisi-
ana’s solicitor general, on
the rule’s supposed benefits.
In 2016, the court decided
that the admitting-privi-
leges rule in Texas provided
no or minimal benefit to
women. Roberts suggested
that health benefits of ad-
mitting privileges would be
the same for Louisiana.
“The impact might be dif-
ferent in different places,”
Roberts said, “but as far as
the benefits of the law, that’s
going to be the same in each
state, isn’t it?”
Murrill disagreed and
tried to argue the benefits of
the law, but she ran into
skeptical questions from the
court’s liberals, led by Jus-
tices Sonia Sotomayor and
Ruth Bader Ginsburg.
They pointed to the diffi-
culties abortions providers
have encountered in obtain-
ing privileges in many cases.
They noted, for example,
that some doctors had ob-
tained privileges at a hospi-
tal in New Orleans or a medi-
cal center in Baton Rouge,
but could not do the same in
the Shreveport area, where
the Hope Medical Group is
the only provider of abor-
tions.
In his comments, Rob-
erts suggested the court
must weigh the benefits and
burdens of the Louisiana law
and decide then whether it
would put an undue burden
on abortion rights.
This could lead to a rela-
tively narrow ruling in the
case of June Medical Serv-
ices vs. Russo.
