Emplacement of seismometers in postholes has progressed greatly in the last decade through availability of purpose-built sensors and through a wide exploration of techniques by seismic network operators and principal investigators. For our purposes here, posthole emplacement can range from shallow to deep, cased to uncased, holes drilled into piers, as well as grouted in sensors. The Best Practices for Seismic Posthole Emplacement project has the following main goals:
By pulling together the expertise of our community, we will be able to put together a public resource of previous experiences and recommendations going forward. This will ensure future seismic posthole emplacements will be of the highest quality possible and will outline the areas ripe for exploration and technical development.
We welcome feedback and plan to gather community input through a variety of methods. A posthole emplacement mailing list is available through the IRIS Message Center at: https://ds.iris.edu/message-center/topic/posthole/ to provide a forum for discussion and for announcements of events. Please consider joining us at one or more of the following events to provide your input and get involved.
Comments are welcome, and we encourage you to get in touch with the organizers with any suggestions, questions, or concerns.
