Scientists Identify Millions 
of Hidden Earthquakes

Mountain Lion Naps in 
Pasadena Backyard

 Caltech seismologists 
announced Thursday they have 
identified nearly two million 
previously unidentified tiny 
earthquakes across Southern 
California occurring between 
2008 and 2017.

 The efforts, published online 
by the journal Science on April 
18, expand the earthquake 
catalog for that region and 
period of time by a factor of 
10—growing it from about 
180,000 recorded earthquakes 
to more than 1.81 million. 
The new data reveal that there 
are about 495 earthquakes 
daily occurring at an average 
of roughly three minutes 
apart. Previous earthquake 
cataloging had suggested that 
approximately 30 minutes 
would elapse between seismic 

 This 10-fold increase in 
the number of recorded 
earthquakes represents the 
cataloging of tiny temblors, 
between negative magnitude 
2.0 (-2.0) and 1.7, made possible 
by the broad application of a 
labor-intensive identification 
technique that is typically only 
employed on small scales. 
These quakes are so small that 
they can be difficult to spot 
amid the background noise that 
appears in seismic data, such as 
shaking from automobile traffic 
or building construction.

 “It’s not that we didn’t know 
these small earthquakes were 
occurring. The problem is 
that they can be very difficult 
to spot amid all of the noise,” 
says Zachary Ross, lead author 
of the study and postdoctoral 
scholar in geophysics, who 
will join the Caltech faculty in 
June as an assistant professor of 
geophysics. Ross collaborated 
with Egill Hauksson, research 
professor of geophysics at 
Caltech, as well as Daniel 
Trugman of Los Alamos 
National Laboratory and Peter 
Shearer of Scripps Institution 
of Oceanography at UC San 

 To overcome the low signal-
to-noise ratio, the team turned 
to a technique known as 
“template matching,” in which 
slightly larger and more easily 
identifiable earthquakes are 
used as templates to illustrate 
what an earthquake’s signal 
at a given location should, 
in general, look like. When 
a likely candidate with the 
matching waveform was 
identified, the researchers 
then scanned records from 
nearby seismometers to see 
whether the earthquake’s signal 
had been recorded elsewhere 
and could be independently 

 Template matching works 
best in regions with closely 
spaced seismometers, 
since events generally only 
cross-correlate well with 
other earthquakes within a 
radius of about 1 to 2 miles, 
according to the researchers. 
In addition, because the 
process is computationally 
intensive, it has been limited 
to much smaller data sets in 
the past. For the present work, 
the researchers relied on an 
array of 200 powerful graphics 
processing units (GPUs) that 
worked for weeks on end to 
scan the catalog, detect new 
earthquakes, and verify their 

 However, the findings were 
worth the effort, Hauksson 
says. “Seismicity along one fault 
affects faults and quakes around 
it, and this newly fleshed-
out picture of seismicity in 
Southern California will give 
us new insights into how 
that works,” he says. The 
expanded earthquake catalog 
reveals previously undetected 
foreshocks that precede 
major earthquakes as well as 
the evolution of swarms of 
earthquakes. The richer data 
set will allow scientists to gain 
a clearer picture of how seismic 
events affect and move through 
the region, Ross says.

 “The advance Zach Ross 
and colleagues has made 
fundamentally changes the way 
we detect earthquakes within 
a dense seismic network like 
the one Caltech operates with 
the USGS. Zach has opened a 
new window allowing us to see 
millions of previously unseen 
earthquakes and this changes 
our ability to characterize 
what happens before and 
after large earthquakes,” said 
Michael Gurnis, Director of 
the Seismological Laboratory 
and John E. and Hazel S. Smits 
Professor of Geophysics

 California Department of 
Fish and Wildlife officers 
along with Animal Control 
carefully removed a large 
100 pound mountain 
lion Thursday from the 
backyard of a home in the 
1600 block of Fiske Avenue 
and Lake Avenue –far from 
the foothills were they 
normally roam.

 According to reports 
and Pasadena Public 
Information Officer Lisa 
Derderian, the large cat 
was seen by residents 
sleeping under a tree. 
Police along with Pasadena 
Humane Society officers 
arrived at the scene shortly 
before 5 p.m. Based on 
its sluggish behavior, the 
mountain lion may have 
been sick and looking for 
food or water according to 

 The animal was sedated 
and removed from the area 
around 7:30 p.m. It will be 
evaluated for any health 
concerns and most likely 
released back into the 
forest Derderian said.

80,000 Eggs Up for Grabs at the Rose Bowl

 City officals are inviting the 
public to celebrate spring by 
hopping over to Pasadena’s fifth 
annual free Egg Bowl today, 
11 a.m.–3 p.m., at Rose Bowl 
Stadium. More than 7,000

and over 80,000 eggs will line 
the historic field.

 There will be three separate egg 
hunts for children up to 12 years 
old. The 11:30 a.m. egg hunt is

City to 
Denim Day

 City of Pasadena employees 
are set to support Denim Day 
on Wednesday by wearing 
jeans as part of Sexual Assault 
Awareness Month –let us 

 For the past 20 years, Peace 
Over Violence has run its 
Denim Day campaign on a 
Wednesday in April in honor 
of Sexual Assault Awareness 
Month. The campaign was 
originally triggered by a ruling 
by the Italian Supreme Court 
where a rape conviction was 
overturned because the justices 
felt that since the victim was 
wearing tight jeans she must 
have helped her rapist remove 
them, thereby implying 
consent. The following day, 
the women in the Italian 
Parliament came to work 
wearing jeans in solidarity 
with the victim. Peace Over 
Violence developed the Denim 
Day campaign in 1999 in 
response to this case and the 
activism surrounding it. Since 
then, wearing jeans on Denim 
Day has become a symbol 
of protest against erroneous 
and destructive attitudes 
about sexual assault. In this 
rape prevention education 
campaign, community 
members, elected officials, 
businesses and students 
are asked to make a social 
statement with their fashion by 
wearing jeans on Denim Day 
as a visible means of protest 
against the misconceptions 
that surround sexual assault.

 “It takes cross-sector 
collaborations and educational 
awareness campaigns, such as 
Denim Day, to bring attention 
to this issue that continues 
to plague our society, and 
ensure we are all informed and 
equipped to combat sexual 
violence. We are thankful 
to Patti Giggans and her 
wonderful team at Peace Over 
Violence for helping create a 
society free of violence,” says 
Norma Fernandez, chair of 
Pasadena’s Commission on the 
Status of Women.

 Pasadena homeowner 
shoots Intruder

 A burglar in unincorporated 
Pasadena learned then 
hard way Thursday after a 
homeowner shot him the 
upper body as he broke into a 
house where the man and his 
two kids were home. 

 The man warned the burglar 
he had a gun, the suspect 
refused to leave. 

 The shooting was reported 
just before 3:30 p.m. in the 
3600 block of Grayburn Road. 

 According to deputies they 
had first gotten a call about a 
burglary at another home in 
the area. A woman was also 
home in that case and the 
intruder fled. They said the 
suspect was likely the same. 

 The homeowner legally 
owned the gun they said.
