Represents Pasadena CA City BoundaryPASADENA FACTSFounding A severe Indiana winter during 1872-73 prompted a group of friends from Indianapolis to form an investment group with the purpose of moving to the warmer climate of Southern California. Sent to scout the area, D. M. Berry recommended purchasing a portion of the Rancho San Pasqual, which later became Pasadena.IncorporationOne of the main reasons Pasadena was incorporated in 1886 was to abolish saloons and the sale of alcohol in the area. In February 1887, an ordinance was passed that banned liquor in Pasadena.NameThe word Pasadena literally means "valley" in the Ojibwa (Chippewa) Indian language, but it has been interpreted to mean "Crown of the Valley" and "Key of the Valley," hence the adoption of both the crown and the key in the official city seal.Namesakes Pasadena, Texas was named after Pasadena, California because some thought that the areas resembled each other.An asteroid was given the name Pasadena in 1980, in part because it is a middle-sized "suburban" asteroid eight miles (13 kilometers) in diameter. The USS Pasadena SSN-752, a nuclear submarine, is the third Navy vessel and first submarine to carry the name of Pasadena. Commissioned in 1989, the submarine has been deployed several times, including the Persian Gulf in 1993. Currently based in Pearl Harbor, the football field sized sub is known for its speed and stealth, as well as, its advanced sonar capabilities and weaponry systems. The USS Pasadena was awarded the Submarine Squadron Seven Battle "E" Efficiency award for 1998. The submarine's insignia was originally designed by Walt Disney for the USS Pasadena (CL-65),a light cruiser that earned six battle stars during WW2, represented by the boxing turtle. The red rose ties the ship to the City of Pasadena. More information about the USS Pasadena can be found on the Navy's Web site or the USS Pasadena Foundation.Official Flower The rose (no particular variety) was adopted as Pasadena's official flower on September 22, 1961.Parrots Naturalized parrots are frequently seen and heard around Pasadena. According to local legend, many were released during a 1959 fire which destroyed Simpson's Gardenland and Bird Farm in Pasadena. Some of the parrots were probably pets that escaped or were set free. Some may have been released by smugglers attempting to avoid arrest. One common breed is the Red-crowned parrot. Rose Bowl The Rose Bowl was constructed in 1922 on the site of a dump in the Arroyo Seco. It originally had a seating capacity of 57,000 and currently seats 100,184 people. The rim circumference is 2,430 feet (741 meters); 880 feet (268 meters) from the north to the south rim and 79,156 square feet (7,354 sq. meters) with a circumference of 1,350 feet (411 meters). The Rose Bowl is home for the UCLA Bruins Football team. Tournament of RosesThe Tournament of Roses annual parade of flower covered floats has been held in Pasadena since January 1, 1890. It was patterned after a European festival of roses and was meant to show off Pasadena's natural beauty and sunny climate while most of the nation lay buried beneath snow. Today, the 5.5 mile (8.8 kilometers) Tournament of Roses parade has magnificent floral floats, marching bands, equestrian units and public officials. Floats must be completely covered with flowers, greenery, or other natural material, with an average float requiring up to 100,000 blossoms. It is estimated that more than one half million roses in vials are used in each parade. The average cost of a finished float is between $75,000 and $250,000 depending on the size and mechanics of the float. About 1,000,000 people come to Pasadena to watch the Tournament of Roses.

This is a global liquefaction susceptibility map (EPSG:4326) based on the geospatial liquefaction prediction models of Zhu et al.^[1] .

The coastal model was applied for areas <20km from the coast. The inland model was applied elsewhere. Refer to Zhu et al. ^[1] in the first instance for further methodology and descriptions.

Input data used in part, or their entirety may comprise (amongst others):

• rivers ^[2-4]
• depth to ground water ^[5]
• precipitation ^[6]
• land ^[7]
• V_s30 ^[8]

Cell values are based on Zhu et al. ^[1] susceptibility classes where:

1. very low,
2. low,
3. moderate,
4. high,
5. very high

0 refers to no data -- typically water bodies.

While this data may be useful as preliminary information for regional-scale planning, a PGV intensity term is required for probability maps. Again, see Zhu et al. ^[1] for a discussion here.

An application using this dataset is seen in Koks et al. ^[9].

This dataset contains the global raster files (at 250 m resolution) associated with a manuscript that has been accepted at the journal Geology:The unexpected global distribution of Earth's sediment sources and sinksHarrison K. Martin1,* and Michael P. Lamb11Division of Geological and Planetary Sciences, California Institute of Technology, Pasadena, CA, 91125, U.S.A.*hkm@caltech.eduThe paper describes a spatially continuous high-resolution (250 meter) global map of sediment source, bypass, and sink domains. If you use the data in your own research or projects, please include references to the paper above and to this dataset.This repository contains three main items: 1) the global raster map, 2) MATLAB code used to create the map, and 3) reduced intermediate data designed to work with the MATLAB code, so that users can recreate or modify the map locally without downloading and processing all of the original input data. The three items are described below. Most users will only need to download the global map (1).Item (1), the global map, is found in the .zip file: "mask_strat_241022.zip"Items (2) and (3), the MATLAB code and intermediate data files, are found in the .zip file: "Source-to-sink Map EE 241022 public.zip"1) Global raster map: The dataset consists of 60 GeoTIFF tiles, each 12,000 pixels by 12,000 pixels (or fewer for edge tiles). Each pixel is 250 meters by 250 meters. Tiles are in the WGS 84 / Equal Earth Greenwich projection (https://epsg.io/8857). For convenience, also included is a .vrt (Virtual Raster) file, which can be opened in your GIS software of choice to load all tiles at once. Tiles are saved as .tif files containing 8-bit integer values, and are compressed using the PackBits algorithm. This substantially reduces the filesize of the resulting dataset without any loss of information.This dataset was created using a combination of QGIS and Matlab, and the method is described in the supporting information of the above manuscript.Pixel values are as follows:0: Ocean (can be set as the noData value in your GIS software for easier visualization)1: Sink2: Bypass3: Source4: Missing Data2) MATLAB code:This code can be run to reproduce our results. It comes in a folder with three subdirectories used to read the inputs and write TIF raster outputs (same as (1) above) and, optionally, PNGs. There is also a .txt file in there with instructions to run the code. I tried to make it as simple as possible to run. I also tried to design it with scientific computing in mind, i.e., able to be run in reasonable time by lower performance computers. Considering it's making a global map, the memory requirements are fairly small. On my computer, it takes less than ten minutes to reproduce the global map.3) Intermediate files:A folder containing ten tiled intermediate datasets, described in the Supplemental Information of the Geology manuscript. This is the input that the MATLAB code in (2) reads. These files go into the "VRTs" folder in the same directory as the MATLAB code. These files are all standardized, compressed, tiled, rasterized at the right resolution and in the right CRS, etc. This folder, including the code, instructions, and intermediate files, is zipped to 188 MB compared to >5.5 GB if users were to download the original datasets themselves. Please feel free to reach out with any questions!- Harrison MartinPostdoctoral Scholar Research Associate in GeologyCaltechJune 24 2025hkm@caltech.eduhttps://harrison.studies.rocksEDIT (25/06/24): Made repository public, uploaded the code and intermediate files, and expanded the description accordingly.
