Many of us have experienced imposter syndrome, which makes us believe that we are unworthy and frauds. It tricks us into minimizing our contributions and value. More critically, impostor syndrome insidiously robs us of future prosperity as it convinces us we do not belong and should not pursue opportunities to advance our career, launch and facilitate exciting new collaborations and be more innovative, inventive, agile and novel in our problem-solving. Consequently, impostor syndrome negatively impacts not only our own potential, but that of the greater STEM community. Let’s knock this out of our brains for good! In this webinar, you will learn strategies and tactics to rid this from your brilliant mind and how to navigate it and stamp it out if it creeps into every day scenarios. Banish impostor syndrome for good!

Let’s be honest, cover letters are annoying to write, and they are an absolutely essential part of the process of a job search. In this webinar, you will learn a recipe to write a cover letter that you can utilize for the rest of your life, whether you are going for an internship, fellowship, scholarship, job or promotion. We will discuss the goal of a cover letter and what elements are included in an effective and compelling cover letter. Then we will write one together, using the recipe. We will address a key aspect of the main part of a cover letter which boils down to Problem-Solution-Result-Spin Back, where applicants really shine as they customize their cover letter. You will emerge with your own customized template to use for any cover letter you write in the future.

It is never an easy time to look for a job, especially during a crisis like we are currently experiencing. This webinar will provide specific tactics you can employ now to find rewarding work. We will discuss effective techniques to clearly communicate your value to potential employers, how and where to find specific types of position announcements, how to access hidden job opportunities, how to use LinkedIn and other social media platforms in your job search, what to do before and during the job search to land the interview and how to navigate virtual interviews. Expect actionable advice to advance your job search!
Networking is the most honorable and valuable endeavor in which you can engage, because it is built on a spirit of generosity. At its core, networking is all about crafting win-win alliances where both parties provide value. You may think that “networking” can only take place in person, but this is a myth! In fact, most networking takes place from afar, and in some cases, the individuals may never even meet in person. In this webinar, we discussed strategies and tactics for finding new collaborators and building mutually-beneficial partnerships with professionals across the globe. We utilized various methods to find and reach out to people to nurture those critical conversations that can birth amazing collaborations! Let’s network! This virtual event was led by Alaina Levine from Quantum Success Solutions and was recorded on 21 July 2020.
Session: Earthquake Source Parameters: Theory, Observations and Interpretations
We develop a method for quasi-automated estimation of directivity, rupture area, duration, and centroid velocity of earthquakes with second seismic moments. The method is applied to small to moderate earthquakes in southern California. P and S phase picks are given by a 1-D ray tracing algorithm and cataloged event locations. These are refined for deconvolution by using a grid search on zero-crossings within a short time window around the automated P/S picks. Source Time Functions (STFs) of target events are derived using deconvolution with a stacked empirical Green’s function (seGf). The use of seGf suppresses non-generic source effects such as directivity in individual eGf’s. The seGf for each target event is based on stacking individual eGfs (normalized by seismic potencies) selected by spatial and magnitude criteria as well as performances in the projected Landweber deconvolution. A weighted stack of eGfs, with weight coefficients grid searched and determined by waveform fits, helps further to correct inaccuracies of focal mechanisms. Compared with a single eGf, analysis with a weighted stack can significantly improve waveform fit and typically allows getting STFs at 5-10 more stations. The method is suitable for analysis of large seismic datasets and it works for target events in southern California with magnitudes as small as 3.5. Most events analyzed so far have significant directivities.

Session: Recent Advances in Dense Array Seismology
The Upper Geyser Basin (UGB) in Yellowstone contains one of the highest concentrations of hydrothermal features on Earth including the iconic Old Faithful geyser. Although this area has been the focus of many geological, geochemical, and geophysical studies, the shallow (<200 m) subsurface structure remains poorly characterized due to limited instrument implementations in this delicate and sensitive environment. The recent availability of seismic dense arrays (large-N) permits an environmental-friendly approach to investigate the detailed crustal structure from the low-cost and easy-deployed geophones. To probe the detailed structure in relation to the hydrothermal plumbing of the UGB, we deployed large-N arrays of 3C 5-Hz geophones in both November of 2015 and 2016, composed of 133 stations with ~50 m spacing, and 519 station locations, with an ~20 m spacing, respectively. We constructed cross-correlation functions (CCFs) and extracted Rayleigh-wave signals between 1-10 Hz via seismic signals excited by nearby hydrothermal features. We observe a clear lateral velocity boundary at 3.3 Hz frequency that delineates a higher phase velocity of ~1.6 km/s in the NE and a lower phase velocity of ~1.0 km/s in the SW corresponding to the local geologic formation of rhyolitic and glacial deposits, respectively. We also image a relatively shallow (10-60 m deep) large reservoir with an estimated porosity 30% located ~100 m southwest of Old Faithful from the significant spatial-dependent waveform distortions and delays between 5-10 Hz. This reservoir is likely controlled by the local geology with a rhyolitic deposit in the NE acting as a relatively impermeable barrier to vertical fluid ascent. In addition to the static structure, we observe temporal variations in both phase and amplitude from the minutely CCFs with regard to the potential influences from instrument resonance, seismic source, and structure. The preliminary results of variations will be demonstrated and discussed.
