Successful Completion of Challenging Yellowstone National Park GPS Installation |
A GPS site located on the Promontory in Yellowstone National Park (P709) was successfully completed during the last week in September. The Promontory is a peninsula between the South and Southeast Arms of Yellowstone Lake. Because of the location and accessibility, this site has been thought from the beginning to be one of the most difficult YNP sites to permit and install. Read more |

Hybrid PBO Sites Shore-NW and Floequarry Will Offer a Comprehensive Look at the Plate Boundary of the Pacific Northwest at all Frequencies |
The Plate Boundary Observatory has met another significant milestone in the MREFC phase. On September 12, 2005, PBO engineers Mike Hasting and Peter Gray completed the first co-located borehole strainmeter (BSM) and GPS site. The combination of these two instruments at one site will provide comprehensive coverage of deformation from 100ths of seconds to 10s of years by collocating seismometer, borehole strainmeter, pore pressure monitor, and precision GPS sensors at a single site.

PBO Borehole Strainmeters Ready for Canada Installations |
Since early August, PBO strainmeter crews have been working on Vancouver Island to create a network of borehole strainmeters. As of this writing, four new boreholes have been drilled on the Island, three at the Pacific Geoscience Center (PGC) located in Sidney, and one at the Ucluelet Coastguard Station on the western side of the Island. Unlike the previous strainmeter installs, a challenge at these Canadian sites has been to contain and remove all liquid and solid matter, or "cuttings," extracted during the drilling operation. This process is required by the site permits so as not to contaminate the local bays with silt from the cuttings. Read more |

Yellowstone Park GPS Installation Update |
Based in Montana for the summer, the Rocky Mountain regional staff is working in the Yellowstone/Teton area to install GPS monuments, set up a communications network, and perform reconnaissance and permitting activities throughout Montana, Wyoming, and Idaho. There are currently eight sites scheduled to be installed in Yellowstone National Park over the next several months: five monument installations this summer and three installed next summer (2006). So far, six of the eight sites have been identified and permitted. Additionally, a few sites just outside of the park are part of the Yellowstone monitoring network. Read more |

GPS Installations Heat up on Akutan Volcano, Alaska |
PBO, with our partners at the Alaska Volcano Observatory, has begun to install continuous GPS stations on the third volcano in the PBO network: Akutan, a 1300-meter-tall composite stratovolcano located in the Aleutian Islands about 1200 km SW of Anchorage, Alaska. Akutan was chosen as a target for PBO GPS studies because it is one of the most active volcanoes in the Aleutians, with 30 recorded historic eruptions including one in 1992, as well as intense ground deformation related to shallow dike intrusion in 1996. Akutan also has diverse magmatic systems, ranging from basalt through rhyolite, though most of its lavas are andesitic. PBO’s GPS studies of Akutan will help us better understand magma movements beneath plate margin volcanoes in a subduction zone, the dynamics of eruptive and intrusive processes, and help scientists improve eruption prediction and volcano hazards mitigation. PBO plans to install eight continuous GPS stations on Akutan during the next few weeks. Read more |

First EarthScope Borehole Strainmeter Installation Completed! |
Excited to complete the final installation steps of the first EarthScope borehole strainmeter, the PBO strainmeter crew began work early on Friday morning. After connecting the AC power at the enclosure, the engineers interfaced the strainmeter and other instruments with the power and opto-isolation systems. Following that, engineers assembled the satellite communications system (VSAT), connected it to the instrumentation, and began testing seismic and strainmeter data communications. Hurray!'

Day Four of First Strainmeter Installation: Putting the Pieces Together |
Upon arriving at the site, we found good news: the concrete successfully blocked up the 6-inch casing, as the artesian water flowing out of the borehole now only comes out of the 2-inch PVC that holds the seismometer. From the opening of the borehole, crews measured 322 feet down to the top of the concrete. This area will be left open to allow the potential for other instruments to be installed in the future.

Day Three: Installation Continues, and First Earthquake recorded! |
Flush with the successful installation of the first PBO borehole strainmeter and seismometer, crews continued to finish work at the Hoko Falls station. The next steps included pouring layers of cement and sand into the borehole. First, 20-foot sections of 1-inch PVC were inserted into the borehole to a depth of 530 feet. After the field crew tested the seismometer and strainmeter instruments one last time for peace of mind, they lined up 94-pound cement bags and large buckets of water beside the mixer. Read more |

First EarthScope Strainmeter Officially Installed! |
Crews arrived at the Hoko borehole site first thing Tuesday morning ready to begin the testing of the strainmeter and continue preparing for the installation. First, crews tested the “trip mechanism” - a device that is used to dispense the grout once the 30’ dump bailer touches the bottom of the borehole. A couple of dry runs to the bottom of the borehole proved successful activation of the trip mechanism upon reaching the floor of the hole. Read more |

PBO Strainmeter Crews Ready for First Installation – Take Two! |
PBO Strainmeter Engineers Bob Mueller, Mike Hasting, and Wade Johnson have been anxiously waiting for this week to arrive. After detecting unwanted noise while testing the first PBO borehole strainmeter during the first scheduled installation in March 2005, crews had to delay installation for “Unit 0” until the problem was identified and repaired. Once the unit was returned to the manufacturer’s labs in Australia, a small amount of condensation was detected in the instrument and was the culprit causing the extra noise. Since then, the problem has been repaired and the strainmeter sent back to the United States for this second installation attempt. Read more |

Installation of the first Strainmeter Instrument (3) |
Crews woke up to drizzling rain and cloudy skies this morning. Despite small openings in the sky, the wet weather persisted intermittently throughout the day. As the installation steps continued to be refined through "dry runs" outside the borehole, testing continued on the strainmeter. Inside the enclosed walls of a large truck to protect from them from the rain, PBO personnel continued to learn the workings and test results of the instrument. Unfortunately, unexplained noise appeared in the test results, and crews spent the rest of the afternoon trying to diagnose the problem. Read more |

Installation of the first Strainmeter Instrument (2) |
Crews met early this morning to begin working on the installation process. Another unusually sunny day in Sekiu, crews started out preparing the grouting pump and mixer. Test batches of grout were mixed to find the ideal consistency for the strainmeter install and to become familiar with the window of time available before the grout sets. Read more |

PBO Borehole Coring Begins: Crews Discover First Strainmeter Instrument Site |
The morning of January 18th 2005 kicked off the next step in the PBO Strainmeter installation process: coring of the drilled boreholes. Coring began at the Goldbeck site, one of the eight boreholes drilled in the Pacific Northwest region. This next step is essential in determining whether or not the chosen borehole location is made up of competent enough rock to host a strainmeter instrument. Read more |

PBO Magmatic Systems Working Group Discusses Y2 Installations |
Members of the Magmatic Systems Working Group convened in Vancouver, WA on January 18, 2005 to discuss scientific priorities for this years upcoming strainmeter and GPS installations located on and around volcanoes and calderas. The group meets once per year to advise PBO on science priorities and provide specific recommendations for station relocations. This year the PBO working group used the USGS Cascades Volcano Observatory facilities to hold the all-day meeting. Site selection and relocation issues were discussed for the Alaska (Aleutians), Rocky Mountain (Yellowstone), Pacific Northwest (Cascades volcanoes), Northern California (Mt. Shasta and Medicine Lake), and Southern California (Long Valley) regions. Committee members discussed recent volcanic unrest combined with existing and planned infrastructure. Read more |
