Western Idaho Shear Zone: is snow in the forecast?

FlexArray Experiment: Western Idaho Shear Zone

If this photo (below) of a 6' 1" tall individual looking up at the top of the solar panel mast doesn't cause one to wonder how much snow the mountains near Cornucopia, Oregon receive, a Snow Cat (below left) at a nearby lodge certain makes it's clear - lots of it. This temporary seismic station installed in the mountains of eastern Oregon is part of Dr. Ray Russo's Western Idaho Shear Zone Earthscope Flexible Array experiment. Spanning eastern Oregon to eastern Idaho, the seismic network covers arguably some of the most remote and rugged mountains of the contiguous United States.

GPS Rollover: Potential Data Logger Performance & Timing Issue

Late 2018 EPIC learned of a GPS week rollover event that can affect data logger performance and timing. EPIC has acquired a GNSS signal generator that can emulate GPS satellite signals. This satellite emulator allows us to test EPIC equipment that relies on GPS timing and to determine how equipment will handle the GPS rollover event. To date, we have determined that some models of GPS engines are affected by the rollover. How the rollover errors manifest is dependent on the data logger’s model and firmware version of the GPS engine.

Seismic Instrumentation Technology Symposium coming to Albuquerque on June 10-11, 2013

The next Seismic Instrumentation Technology Symposium (ITS2013) will be held in Albuquerque, NM on June 10th and 11th, 2013, at the Sheraton Albuquerque Airport Hotel.

The EarthScope website has a page for the conference, with the agenda, participants, and registration form.

The theme of this symposium is to examine future technology, both from the perspective of capabilities scientists and engineers are seeking and the technologies that are, or will be, in the product pipeline of the seismic technology industry. The symposium will provide a forum for perspectives from both technology users and vendors and allow generous time for discussion and interaction.

New Mexico Tech to Expand EPIC

Daniel H. López, president of New Mexico Institute of Mining and Technology (New Mexico Tech) in Socorro, authorized the expansion of the on-campus building that houses the EarthScope EPIC and the EarthScope Array Operations Facility. The 1300 square foot addition, scheduled for completion in Spring 2009, will primarily provide laboratory and office space for EPIC’s recently expanded Polar Program activities supported primarily by the National Science Foundation’s Office of Polar Programs.

Programming a Q330 with Willard

Willard is Quanterra's program to program and control Q330's. It is a standalone Windows program which allows you to set parameters, monitor data acquisition, storage, gps power cycling, sensor control, and much more. It is a very powerful and complex program which does not lend itself to a brief 'walkthrough' via a webpage.

Due to its complexity and ability to control every aspect of a Q330, it is very easy to make a severe mistake which would make the Q330 not function as intended. We highly recommend that only experienced users of Willard program Q330 parameters. You should contact a EPIC staff member if you have any questions regarding using Willard to program a Q330.

During training at EPIC, users receive a walkthrough of Willard.

 

Updating Firmware For Q330's

Upgrading Q330 firmware is done with the program Willard.

 

Setup: Download the required firmware from http://q330.com/ Place the firmware into a folder with the name of the firmware (in this example the folder name would be "1.80"). Note: This is important because all Q330 firmware files are named identically. To keep them separated, they must be stored in separate folders.

 

Willard:

Power up the Q330 and connect it to computer via console cable.

Start Willard and select console registration.

 

Select "No" if asked to create a dataless station.

 

 

Quanterra Q330

The Q330 is a 3 or 6 channel high resolution datalogger. It is low power and highly configurable for a wide range of applications and sensors. The Q330 is housed in a sealed aluminum enclosure which makes it highly resistant to the environment. Telemetry is a main focus of the Q330, but it also has a robust on-site data storage system which uses external Balers. This makes it easy to swap out the data storage on-site for when servicing doesn't allow an extended visit. The Q330 can write data to four different receiving systems simultaneously. It also has built-in sensor controls, an automatic mass recentering feature, and calibration functions. The Q330 is programmed with a Windows program called Willard, it can also be controlled by a PalmOS program for when working in the field.

December 31 2016 Leap Second

Leap Second's effect on EPIC RT-130 and Q330

Summary:

Q330:

Data time starting at 2017:001:00:00:00 is +1 second from truth for 1-2 minutes (seen in controlled tests) until a clock correction, followed by a gap of 2-40 seconds per channel depending on sample rate.

RT-130:

Data time starting at 2017:001:00:00:00 is +1 second from truth for 15min - 9:42hrs (seen in controlled tests) until a clock correction. Some data (~6secs in tests) around the time correction is mistimed, sometimes 11 years in the future, or missing.

Geospace Y-28 (GS11-3D) High Frequency Sensor

  Salient Features: This 3-channel sensor has a frequency of 4.5Hz, is critically damped at .707 and has a sensitivity of 32 V/m/s. Used for (but not limited to) active source (land and off-shore excitations), glacial movements, local earthquake and aftershock studies.
