The volcano continues to emit a high volume of sulfur dioxide measured at an average of 1,916 tons per day while GPS and tiltmeter
readings indicate a sustained swelling of the volcano's slopes, the bulletin said.
In the past, varied sensors have been widely used in bridge testing to obtain information on bridge performance, such as camera, fiber optic, electrochemical, accelerometer, strain gauge, tiltmeter
, acoustic emission, temperature sensors, just to name a few.
The 875 Mini Tuff Tilt Series is the newest addition to Jewell's tiltmeter
(inclinometer) line for geophysical & geotechnical applications.
A built-in inclinometer (tiltmeter
) helps you accurately set the altitude adjustment.

Recent advances in a number of scientific and technological fields (accurate astrometric reference star catalogs, development of digital imaging technology, high accuracy tiltmeter
technology, and, most of all, geocentric coordinate availability using GNSS) have made it possible to use astrometric methods for accurate, fast and automated determination of vertical deflections.
The combination of Pinnacle's tiltmeter
and microseismic technology has been brought into the customers' visualisation environment.
