SOUTHERN CALIFORNIA SEISMOGRAPHIC NETWORK A Cooperative Project of Caltech and the U.S. Geological Survey February 22, 1996 Weekly Earthquake Report for Southern California February 15 21, 1996 Prepared by: kate@bombay.gps.caltech.edu) Lucy Jones, U. S. Geological Survey California Institute of Technology For further information, please contact the authors or the Caltech Public Relations Office at 8183956326. For daily updates, call our Earthquake Information Hotline: 8183956977. This week's Report covers the time period from midnight Thursday morning, February 15, Universal Time (ie. GMT), to midnight Wednesday night, February 21, Universal Time. In local time, the period of coverage is from 4 p.m., February 14 to 4 p.m., February 21, Pacific Standard Time. We detected and processed 378 earthquakes during the 7day period covered. Of the three quakes felt this week, two were aftershocks and one was not. The first felt quake occurred last Thursday afternoon, near Simi Valley. It had a magnitude of M2.9 and was an aftershock of the January 17, 1994 Mw6.7 Northridge quake. The second felt quake occurred on Saturday evening near Compton, with a magnitude of M2.8. The third, on Wednesday morning, was a Landers aftershock (of the June 28, 1992 Mw7.3 quake), magnitude M3.8. It was felt in Yucca Valley and lso in Barstow. The Landers aftershock had the expected strikeslip focal mechanism. The Compton quake had a thrust mechanism, on an east northeast striking fault. Two other M3+ quakes occurred this week. One was last Thursday afternoon in Imperial Valley, M3.0, and the other was a Landers aftershock, M3.2, early Monday morning. The table lists the quakes this week that were M2.0 or larger in the central part of the coverage area. Times are local times; if you want Greenwich Mean Time, add 7 hrs to the Pacific Daylight Time or 8 hrs to the Pacific Standard Time listed. > WHY DID I CHANGE TO COURIER FONT HERE?

UNDER CONSTRUCTION
On January 17, 1994 the magnitude 6.7 Northridge earthquake shook the lives of
southern Californians. It was the eighth damaging earthquake to strike southern
California in eight years. The first large earthquake to strike directly under
a modern urban area, it spurred renewed examinations of the threat we face.
One year after the Northridge, California earthquake, our hearts went out to the
people of Kobe, Japan, as they faced their own, more devastating earthquake on January 17, 1995. Their tragedy reminded us that awareness of the earthquake threat
is not enough. Awareness must lead to actionyour action.
Earthquakes are inevitable, but the damage from earthquakes is not. We
can construct buildings that will not fall down and bridges that will sway, not
break. On a personal level, we can secure computers and water heaters to keep
them from breaking, install safety glass, and keep heavy objects away from our
beds. We can store water and practice family safety plans to overcome fear and
better cope with the aftermath of earthquakes. The lesson of the last decade of
earthquakes is that you can make your home, your workplace, and your family
safer.
This document is based on the "Putting Down Roots in Earthquake Country"
handbook released to Southern Californians in October of 1995. It is divided into a number
of sections to help you find the information you want. This document is a resource to
turn to with your questions. If you only want to know how to make yourself safer,
go straight to
the "Taking Control" link. If you are interested in the science of
earthquakes and want to understand how scientists evaluate the
earthquake hazard, you might want to
start with the "Reviewing the Basics" link.
> WHAT IS ANOTHER HIGH TECH WAY TO ORDER BOOKLET (SOUNDS GOOD, BUT DID NOT WORK FOR ME. JA) or send email to ScecInfo@usc.edu. FOLLOWING IS THE HTML "MAKING YOUR HOME SAFE FROM EARTHQUAKES"
Earthquake safety is more than keeping our buildings from falling down. We must
secure the contents of our buildings to reduce the risk to both our lives and
our pocketbooks. Four people died in the Northridge earthquake because of damage to building contents, such as toppling bookcases. Many billions of dollars were lost due to nonstructural damage. Nonstructural safety is up to you. The hazard hunt showed potential problem areas of your home. Here we show you just what you can do to secure possessions inside your home. You should secure anything 1) heavy enough to hurt you if it falls on you, or 2) fragile and/or expensive enough to be a significant loss if it falls. Most hardware stores now carry earthquake safety kits or the raw materials for you to make your own earthquake fasteners.
SECURING TABLETOP OBJECTS TVs, stereos, computers, lamps, and chinaware are heavy and costly to replace. They can be secured with buckles and safety straps attached to the tabletop (which allow easier movement of the unit when needed) or with hook and loop fasteners glued to both table and unit. Glass and pottery objects can be secured with nondrying putty or microcrystalline wax, available at many stores. IN YOUR KITCHEN Unsecured cabinet doors fly open during earthquakes, allowing glassware and china to crash to the floor. Many types of latches are available to prevent thischildproof latches, hook and eye latches, or positive catch latches designed for boats. Gas appliances should have flexible connectors to reduce the risk of fire. OBJECTS FROM ABOVE Ceiling lights and fans can be very heavy and present a significant safety hazard. These should be additionally supported with a cable bolted to the ceiling joist. The cable should have enough slack to allow it to sway. Framed pictures, especially glasscovered, should be hung from closed hooks so that they can't bounce off. Only soft art such as tapestries should be placed over beds or sofas. Protecting yourself from broken glass Window glass can shatter during earthquakes and presents a significant hazard. Windows made from safety glass or covered with a strong mylar film are much safer. Be sure you use safety film and not just a solar filter. ANCHORING YOUR FURNITURE Secure the tops of all, topheavy furniture such as bookcases and file cabinets to the wall. Be sure to anchor to the stud, and not just to plasterboard. Flexible fasteners such as nylon straps allow tall objects to sway without falling over, reducing the strain on the studs.
