Survey about earthquakes
in California
1. What do you think are the biggest problems after (occured) earthquakes?
e) Destroyed infrastructure (bridges etc.)
2. What was the magnitude of the most intensive earthquake you’ve ever experienced?
Magnitude (Richter scale):
e) 6-7
3. How often do earthquakes occur in your area?
I can't answer this question with the options provided. There may be daily earthquakes up and down California, but if you talking about feeling earthquakes, it's more like yearly. No where near monthly.
4. What arrangements does the government make concerning the limitation of damage?
c) Earthquake-proved“ buildings, bridges (elastic)
5. Does the government participate in the compensation for damage (destroyed house)? If yes how much?
That sounds like more of a personal insurance issue. There are relief efforts if needed, but I don't know the percentage that comes from the government.
6. In what way are you prepared/shielded against earthquakes?
d) I’m not prepared at all, nor shielded.
e) Earthquakes usually don’t affect me
7. What are you concerned with most at the moment?
a) Economic crisis
8. How often do you think about earthquakes and their danger?
e) Monthly
(This question would be better if the options were qualified/rated as: All the time, Often, Sometimes, Never)
9. What scenario makes you most afraid?
d) An assault
10. Suppose, an eathquake destroyed your house, what would you do?
b) Rent a flat in the same town (already rent)
11. In what way are you interested/engaged in earthquake researches?
d) I’m not engaged, but I usually look for new discoveries (I think articles on earthquakes are interesting to read, but I'm not personally looking for new discoveries. Is that what you meant?)
12. Where do you get the information? (linked to question before)
a) Newspaper
e) TV
Interview: USGS Quake Expert on Likelihood of 9.0 Earthquake in California and Pacific Northwest
On Friday, after the massive earthquake and subsequent tsunami had hit Japan, Gretchen Weber of KQED's Climate Watch spoke with Tom Brocher, Director of the Earthquake Science Center at the U.S. Geological Survey in Menlo Park. Pretty interesting conversation for those of us who live in quake territory. After cautioning to be mindful of the tsunami's effects for 12 hours after the first waves struck (the tsunami advisory has now been canceled), he got into the subject of giant earthquakes.
Some things that Mr. Brocher pointed out:
- The type of giant quake that hit Japan Thursday is not expected to menace the Bay Area, where the 7.9 quake of 1906 is thought to be at the upper limit of quakes in the area. The Japan quake was 30 times larger than the 1906 quake, and 900 times the size of the Loma Prieta temblor in 1989.
- North of California, however is another story. A magnitude 9.0 or above quake in the Pacific Northwest is expected. Those quakes, which are the product of vast and deep faults, are characterized by their severity and the duration of shaking when they strike. Brocher said strong shaking lasted for 3-5 minutes during Thursday's tembler.
- A quake in the 9.0 range occurs in the Pacific Northwest region every 300 - 500 years. The last one was in 1700, which scientists know because of a tsunami that was recorded in Japan at the time.

Frequently Asked Questions
What is an accelerometer? What is an accelerograph? And what is an accelerogram?
An accelerometer is a sensor that measures acceleration, like a speedometer measures speed. An accelerometer is often part of an accelerograph, which is an instrument that contains accelerometers and records the acceleration record. The acceleration record is called an accelerogram. Note the similarity to something much more familiar: The telegraph, is an instrument, and it produces a record that is called the telegram
What is acceleration? What does “g” stand for?
Acceleration, in physics, corresponds to the force applied to something that causes it to change its position or speed. It is the force you feel when a car accelerates from a stop sign, pushing you back into the car seat (it’s a horizontal force). Similarly, when an elevator starts moving, you feel more weight on your legs (it’s a vertical force). When a roller coaster car makes a hairpin turn, the acceleration may push you to the side, or up or down.
Acceleration is measured in “g”, where 1 g corresponds to the vertical acceleration force due to gravity. Roller coasters experience accelerations of 2 or more g, and fighter pilots may have to handle accelerations of 8g or more without passing out.
During an earthquake, the forces vary a lot and keep changing, back and forth and side to side. These forces, if they’re strong enough, can damage structures unless the structures have been specially designed. The largest earthquake forces that have been measured are about 1 to 2 g; most earthquakes have much lower forces, but those forces can still damage many structures.
What does strong motion mean?
The motion of a point on the ground during a small or distant earthquake can be so small that only specialized, precision instruments can record it. When the earthquake is larger (or closer), that motion will be larger. When the motion reaches the level where humans can feel it, typically a 1-2 %g, it is often called strong motion. This is an actually an arbitrary level, meant to communicate the level qualitatively, as when one says “heavy rain” vs. “light rain”.
What other sensors besides accelerometers are used to measure earthquake motion?
The most common sensor is not the accelerometer, which measures acceleration, but the seismometer, which measures the velocity or speed of a point on the ground as it moves during earthquake shaking. Most velocity sensors are high precision, sensitive instruments designed to record motions from distant earthquakes rather than the strong shaking that occurs near to earthquakes. Another instrument is the displacement sensor, which can be used in certain applications; in strong motion, they are most useful in measuring relative displacement (the distance between two points). Finally, GPS position sensing has become available and can be used to track the position of a point. Earthquake forces changes so rapidly during an earthquake that they must be measured many times each second (as many as 200). GPS doesn’t measure changes that rapid, but is ideal to get final ********s after an earthquake.
Why do you measure acceleration, instead of velocity, or displacement?
Acceleration gives the forces directly, so it can be used to establish the forces that a structure experiences during an earthquake. Also, acceleration sensors are generally the most hardy of all seismic sensors. In addition, they are usually small, only a few inches on a side, so they are easy to place at key ********s in a structure. The acceleration record can be computer processed and integrated to obtain the velocity and displacement records.
What does near-real-time vs. real-time mean?
A real-time signal is continuously being sent and received, with little or no delay, much like a newscast or program on TV. Near-real-time is delayed slightly because a communication link is established to send the data once an event occurs, much as one makes phone call to someone in order to give them a message. Near-real-time communication is generally more economical than a continuous data link, which makes it attractive for communication of infrequent events like the occurrence of earthquake shaking. Real-time communication is thought to be more reliable, but a big earthquake can interrupt many conventional communication pathways. To achieve the most robustness, all types of communication paths should be used achieve maximum redundancy (as is being done in CISN).
What is the difference between Richter magnitude and acceleration?
The Richter magnitude indicates the size or strength of an earthquake. For illustration, a parallel can be drawn with how the strength of an explosion will often be reported in terms of tons of TNT (or sticks of dynamite, in old movies). In contrast, the acceleration, or “g force” usually refers to the shaking experienced at a specific point due to the earthquake. This shaking is generally lower at greater distances from an earthquake, just as the sound level experienced from the dynamite blast is lower at points farther away from the explosion.
What does TriNet stand for?
What does CISN stand for?TriNet is a combined seismic network involving the networks of three agencies, Caltech, the US Geological Survey in Pasadena, and the California Strong Motion Program (in the Department of Conservation’s California Geological Survey). The TriNet effort was primarily supported by FEMA, through OES, as a result of the 1994 Northridge earthquake, and the funding ended for that in late 2000.CISN is the California Integrated Seismic Network, and similar to TriNet but with the addition of two northern California networks, the US Geological Survey in Menlo Park and UC Berkeley. With State support through OES, and federal support though the ANSS effort of the USGS, it makes the effort statewide.
Where can I find lists of strong-motion stations in California?
The lists of strong motion stations in California of the CSMIP and NSMP can be found on the web site of each program. In addition, the Northern and Southern California Seismic Networks maintain lists of seismic stations of their networks for both strong and weak motion stations.
Where can I find strong-motion data?
There are several strong-motion data collections for earthquakes of California and elsewhere. These include the CISN Engineering Data Center, of which the primary data sources are the CSMIP and NSMP networks, in CISN. For data immediately after an earthquake, see the “Internet Quick Report” at the Engineering Data Center. Additional data collections are the PEER database and COSMOS Virtual Data Center. For earthquakes outside California, the NSMP and COSMOS Virtual Data Center also host datasets for the US and selected regions in the world. An important European data collection can be accessed at the European Strong Motion Database, and Japanese records can be obtained at Kik-Net.
What types of buildings/structures does CSMIP instrument?
The CSMIP installs earthquake-monitoring devices in structures such as buildings, hospitals, bridges, dams, utilities and industrial facilities. The program has installed more than 1000 stations, including 700 ground-response stations, 170 buildings, 20 dams and 60 bridges. Sites are selected according to long-term strategies developed in consultation with the Strong Motion Instrumentation Advisory Committee, a committee of the Seismic Safety Commission.
What are the products of strong-motion data?
Strong motion data are used both for earthquake emergency response and for engineering and scientific research. For earthquake emergency response, applications such as the ShakeMaps use strong-motion data as input and generate near-real time information on the levels of ground shaking and loss assessment for emergency responders. Research products in engineering and scientific applications include evaluation of building/structure performance, near surface wave propagation and attenuation, local site characterization, and strong motion prediction, etc.
How do I find out about recent earthquakes in California?
Near-real-time earthquake maps and lists are available at the USGS Pasadena and in Menlo Park recent-earthquake sites and at the Southern California Earthquake Center.
Maps of shaking, called ShakeMaps, which show the areas of ground shaking for significant recent earthquakes are available for both Northern California and Southern California.

Step 2: Make a plan
Planning for an earthquake, terrorist attack, or other emergency is not much different from planning for a party or vacation. Make sure that your emergency plan includes evacuation and reunion plans; your out-of-state contact person's name and number; the ******** of your emergency supplies and other pertinent information. By planning now, you will be ready for the next emergency.

Step 3: Make disaster kits
Everyone should have disaster supplies kits stored in accessible ********s at home, at work and in your vehicle. Having emergency supplies readily available can reduce the impact of an earthquake, a terrorist incident or other emergency on you and your family. Your disaster supplies kits should include food, water, flashlights, portable radios, batteries, a first aid kit, cash, extra medications, a whistle, fire extinguisher, etc.

Step 5: DROP, COVER, and HOLD ON!
Learn what to do during an earthquake, whether you're at home, at work, at school or just out and about. Taking the proper actions, such as "Drop, Cover, and Hold On", can save lives and reduce your risk of death or injury. During earthquakes, drop to the floor, take cover under a sturdy desk or table, and hold on to it firmly. Be prepared to move with it until the shaking stops.

Step 6: Check it out!
One of the first things you should do following a major disaster is to check for injuries and damages that need immediate attention. Make sure you are trained in first aid and in damage assessment techniques. You should be able to administer first aid and to identify hazards such as damaged gas, water, sewage and electrical lines. Be prepared to report damage to city or county government.

Step 7: Communicate and recover!
Following a major disaster, communication will be an important step in your recovery efforts. Turn on your portable radio for information and safety advisories. If your home is damaged, contact your insurance agent right away to begin your claims process. For most Presidentially declared disasters, resources will also be available from federal, state, and local government agencies.
