Strong Earth Motion, Weak Earth
Motion & Vibration Monitoring Instrumentation
BWSGEOFYSIK is now representing a high quality European instrument
manufacturing company providing instrument services for long term earthquake
event recording and vibration measurement or recording here in the United
States of America. These systems range from portable accelerographs,
up to large permanently installed data acquisition system.
No "serious" University or College department of Geophysics should
be without such a system in my view. The USGS and other
international organizations that are involved with earthquake monitoring
can benefit greatly from increased monitoring points on the earth's surface
as data can be summed together or networked together with other monitoring
stations to provide greatly increased accuracy for the location of epicenter
and hypocenter of earthquake events. This line of instrumentation
provides 24 bit resolution at a very competitive prices and with the right
configurations can also be used for engineering vibration studies.
Please view the pictures below and read the descriptions. A
typical least expensive monitoring system with a 3D sensor, a 24
bit recording system with a PCMCIA recording card and/or Gigabyte hard
drive will cost in the neighborhood of $6,000.00 to $7,000.00 dollars.

As a Geophysicist
I believe the recording system Pictured to the left is of the highest quality
on the market today. It can be connected in with a 24
bit 3D accelerometer for very precise measurements of strong or weak
earth motion. You can purchase an external LCD screen so that viewing
of the data over three channels can be seen 24 hours per day. You can use
a PCMCIA card to store smaller amounts of data and/or an external hard
drive for longer time intervals. The amount of data stored
depends on how long a time interval you wish to record. The
PCMCIA card can be ejected out of the unit and data from a previous time
period can be examined with the standard software that is included with
the purchase of the system. This software is designed for the Windows
95,98,2000 and NT systems. This unit is very cost effective
can greatly increase the interest of students in earthquake geophysics
at colleges and universities through out the United States.
SM -2 more detail
picture to the left shows the ope front panel of the SM 2 recording system.
Note the PCMCIA card in the middle but toward the top. This
little card can record quite a large volume of data over three channels,
depending upon the sample rates used.
AC-23 Accelerometer 3D Sensor
is a typical sensor that can be hooked up to the SM-2, there are
also "velocity sensors" that can be hooked up into the SM-2.
This sensor has three degrees of sensing at up to 24 bits of digital resolution.
It can be placed anywhere on a flat surface permanently bolted or cemented
to the ground or left un-attached to the ground's surfrace for portable
