Map data from landslides triggered by Hurricane Maria in a section of Naranjito, Puerto Rico Hurricane Maria caused widespread landsliding throughout Puerto Rico during September 2017. Previous detailed landslide inventories following the hurricane include Bessette-Kirton et al. (2017, 2019). Here we continue that work with an in-depth look at a portion of northwest Naranjito, which is a municipality in the northeastern part of the main island. To study a characteristic sample of landslides in Naranjito, we mapped all visible individual landslides in an approximately triangular area 2.3 km wide by 1.9 km long. The boundary of our mapping was defined by previous studies (Bessette-Kirton et al., 2019). We used aerial imagery collected between 9-15 October 2017 (Quantum Spatial, Inc., 2017) to map landslide...

Much of the Utuado municipality in central Puerto Rico was severely impacted by landslides. Landslide density in this region was mapped as greater than 25 landslides/km2 (Bessette-Kirton et al., 2019). In order to better understand the controlling variables of landslide occurrence and runout in this region, four 2.5-km2 study areas were selected and all landslides within were mapped in detail using remote-sensing data. Included in the data release are five separate shapefiles: geographic areas representing the mapping extent of the four distinct areas (map areas, filename: map_areas), initiation...

Along with the flooding, there were fluvial erosion hazards (FEH) associated with a large amount of erosion in headwater areas. Of special concern were FEHs associated with gullying, loss of wetland storage, and valley-side mass wasting. In 2020, a pilot study was begun to map and classify ephemeral and perennial streams and wetlands in terms of their susceptibility to fluvial erosion hazards. This study combines rapid geomorphic field assessments of river corridor erosion and coupled sediment and debris delivery with...

Data were collected between June and October 2021 at five lakes. Four lake locations (Nearshore, Open Water, Layer, Bloom) were sampled representing one of four sample types (Bottom Sediment, Surface Water, Bloom Material, Layer). Water-quality field parameters (water temperature, dissolved-oxygen concentration and percent saturation, pH, specific conductance, turbidity, chlorophyll fluorescence, phycocyanin fluorescence, and fluorescent dissolved organic material) were measured at each sampling location from the surface to the...

The contents of these lakes and impoundments are reported to Massachusetts Department of Conservation and Recreation (DCR) and classified as one of five levels for drought severity ranging from level 0 (Normal; percentile greater than 30) to level 4 (Emergency; percentile less than 2). Lake and impoundment system data are provided at the end of each month to DCR through multiple agencies as lake levels, volumes, or percent-full (reservoir capacity). USGS reviewed data from 14 of the lake or impoundment systems including 28 waterbodies. Diagrams for...

Much of the Lares municipality in central-western Puerto Rico was severely impacted by landslides. Landslide density in this region was mapped as greater than 25 landslides/km2 (Bessette-Kirton et al., 2019). In order to better understand the controlling variables of landslide occurrence and runout in this region, three 2.5-km2 study areas were selected and all landslides within were mapped in detail using remote-sensing data.

This dataset contains 25,838 earthquakes in 364 well distributed clusters. Currently there are more than 4.5M arrival times with the majority being the Pg, Pn, P, Sg, Sn and S phases. The term “calibrated” refers to the property that the hypocenters are minimally biased by unknown Earth structure and that the uncertainties are meaningful. Uncertainties are calculated using empirically determined variability of the arrival time data itself, specific to each calibrated cluster of hypocenters. The data are carefully processed...

For this study we developed a novel passive method to measure for dissolved radon in groundwater using a coupled diffusive membrane encasing an alpha track (AT) detector. The membrane is gas permeable but water impermeable, which allows for the deployment of AT detectors in aqueous environments. The alpha track (AT) detectors measure the alpha decay of radon as it etches a film seated in the AT. Empirical relations have been developed to convert the etches or tracks from the film of the detectors to a radon concentration. Encasing the AT detectors in a membrane (called MAT detectors) prevents water from deteriorating...
