Detailed Description

Observations of a Yellowstone Lake seiche that began on 12 July 2012, apparently initiated by passing of a barometric high associated with high winds. Seiche is directly observed by an Absolute Pressure Gauge (APG) in the lake (top), and subtle ground motion from the seiche is observed by Borehole Strainmeter instruments at nearby Grant Village (middle) and distant Canyon Village (bottom). The strong 78-minute seiche signal begins during a passing weather front. (The signal with 12-hour period is from the always-present solid earth tide).
