20 pages, 9 figures, 1 table, supporting information https://doi.org/10.1029/2022JB024097.-- Data Availability Statement: Raw seismic waveforms used in this study are available from the IRIS platform (https://ds.iris.edu/ds/nodes/dmc/). Network codes are C1, C, and G. Data preparation and preprocessing were performed using the ObsPy package (Beyreuther et al., 2010). Most of the figures were made with the Generic Mapping Tools (GMT) package (Wessel & Smith, 2006) and the Matplotlib library (Hunter, 2007), In the South-Central Andes, the crustal structures driving the tectonic evolution of the Andean Cordillera remain unresolved. So far, most seismological studies focused on the subduction interface, leaving crustal seismicity and its relationship with crustal deformation and Andean volcanism mostly unconstrained. However, because of their large number compared to higher magnitude events, the characterization of small-magnitude crustal earthquakes is key to identify active structures and better constrain the tectonic models. In this work, we exploit 53 months of continuously recorded, three-component waveforms from the permanent seismic network in central Chile using a deep-learning approach to improve the detection of small-magnitude earthquakes. To increase station coverage, we also use the seismic phases obtained from a previous temporary seismic deployment. We use the obtained seismicity catalog to refine tomographic models of that region, revealing a more detailed architecture of the Chilean forearc. Travel times calculated in the new 3-D velocity model allowed us to locate ∼14,000 earthquakes. Refined double-difference relocations of ∼4,900 events located beneath the West Andean Thrust suggest a large-scale, west-dipping structure which, together with the west-verging tectonic front, likely contributed to the uplift and crustal deformation during the past ∼20 Myr, This research has been supported by the Agencia Nacional de Investigación y Desarrollo (ANID) of Chile (FONDECYT grant N3200633).

While many studies have investigated consumer purchase behavior in reward programs, a better understanding of customer redemption behavior is lacking, particularly when promotions affect a core aspect of reward programs—free rewards. In this paper, we examine the impact of a promotion on purchase and reward redemption in a reward program in which consumers can partially cover the cost of a free reward with their money. The literature on reward programs suggests a positive reinforcement caused by reward redemption, whereas the literature on promotion provides different views regarding the existence of a postpromotion dip. Using data from a major retailer’s reward program, we verify that such a promotion attracted customers with less transaction activity and shorter tenure. Interestingly, consumers using the promotion increased their preference for hedonic rewards compared to their previously observed behavior. This change in preference persisted after the promotion ended. Overall, the promotion significantly increased the number of redemptions but generated a negative impact on subsequent consumer behavior by decreasing purchase incidence and quantity. Our findings point to a need to understand the trade-off between spending money on buying an otherwise free reward and future regular purchases.
