Hello Alex - I have cc'd Jeff Freymueller on this email, who is the person who would know if this data exists, and how to get it to you if it does. Thank you, Cheryl Cameron -------- Alexander Steele wrote: Dear AVO, I am a PhD student at University College London (UCL). I have been analyzing combined precursory deformation and earthquake data during episodes of unrest that have either lead to an eruption, or which have ultimately failed to culminate in eruption. The aim is to look for changes from elastic to inelastic deformation in the crust as the unrest episode progresses. I have recently been analyzing precursory deformation data from Okmok prior to the 2008 eruption. I have mainly been analyzing data found in the literature. However, all the publications that I have looked through only show cGPS measurements up to about mid-2007 (e.g. Fournier et al., 2009). I would like to know if cGPS measurements are available for the year preceding the eruption on the 12 July 2008, and if so is there a way to obtain this data? Ideally, data from stations OKCD or OKCE would be best but any deformation data for this period of time would be great. A plot of the time series would be sufficient. Also, the deformation data that I require is not restricted to cGPS measurements (other techniques would be fine too). Please let me know if you can help on this.
