Conditions beneath the surface are often unstable already, so the heavy rains act as the last straw that causes mud, rocks, or debris- or all combined- to move rapidly down mountains and hillsides. Unfortunately, people and property are often swept up in these unexpected mass movements. Landslides can also be caused by earthquakes, surface freezing and thawing, ice melt, the collapse of groundwater reservoirs, volcanic eruptions, and erosion at the base of a slope from the flow of river or ocean water. But torrential rains most commonly activate landslides. A new model has been developed to look at how potential landslide activity is changing around the world. A global Landslide Hazard Assessment model for Situational Awareness (LHASA) has been developed to provide an indication of where and when landslides may be likely around the world every 30min. This model uses surface susceptibility (including slope, vegetation, road networks, geology, and forest cover loss) and satellite rainfall data from the Global Precipitation Measurement (GPM) mission to provide moderate to high “nowcasts.” This visualization shows the landslide nowcast results leveraging nearly two decades of Tropical Rainfall Measurement Mission (TRMM) rainfall over 2001-2016 to identify a landslide climatology by month at a 1 km grid cell. The average nowcast values by month highlight the key landslide hotspots, such as the Southeast Asia during the monsoon season in June through August and the U.S. Pacific Northwest in December and January. Overlaid with these nowcasts values are a Global Landslide Catalog (GLC) was developed with the goal of identifying rainfall-triggered landslide events around the world, regardless of size, impact, or location. The GLC considers all types of mass movements triggered by rainfall, which have been reported in the media, disaster databases, scientific reports, or other sources. The visualization shows the distribution of landslides each month based on the estimated number of fatalities the event caused. The GLC has been compiled since 2007 at NASA Goddard Space Flight Center and contains over 11,000 reports and growing. A new project called the Community the Cooperative Open Online Landslide Repository, or COOLR, provides the opportunity for the community to view landslide reports and contribute their own. The goal of the COOLR project is to create the largest global public online landslide catalog available and open to for anyone everyone to share, download, and analyze landslide information.

These two regions don't mix except in certain special areas. The ocean currents, the movement of the ocean in the surface layer, are driven primarily by the wind. In certain areas near the polar oceans, the colder surface water also gets saltier due to evaporation or sea ice formation. In these regions, the surface water becomes dense enough to sink to the ocean depths. This pumping of surface water into the deep ocean forces the deep water to move horizontally until it can find an area on the world where it can rise back to the surface and close the current loop. This usually occurs in the equatorial ocean, mostly in the Pacific and Indian Oceans. This very large, slow current is called the thermohaline circulation because it is caused by temperature and salinity (haline) variations.This animation shows one of the major regions where this pumping occurs, the North Atlantic Ocean around Greenland, Iceland, and the North Sea. The surface ocean current brings new water to this region from the South Atlantic via the Gulf Stream and the water returns to the South Atlantic via the North Atlantic Deep Water current. The continual influx of warm water into the North Atlantic polar ocean keeps the regions around Iceland and southern Greenland generally free of sea ice year round.The animation also shows another feature of the global ocean circulation: the Antarctic Circumpolar Current. The region around latitude 60 south is the only part of the Earth where the ocean can flow all the way around the world with no obstruction by land. As a result, both the surface and deep waters flow from west to east around Antarctica. This circumpolar motion links the world's oceans and allows the deep water circulation from the Atlantic to rise in the Indian and Pacific Oceans, thereby closing the surface circulation with the northward flow in the Atlantic.The flows in this visualization are based on current theories of the thermohaline circulation rather than actual data or computational model runs. The thermohaline circulation is a very slow moving current that can be difficult to distinguish from general ocean circulation. Therefore, it is difficult to measure and simulate.This visualization was produced for the Science On a Sphere production \"Loop\". It is intended to be over-layed on a world map background. Below are 3 sets of 4 sequences. The first set of 4 sequences are all composited over a world map background with a limited number of frames that make them loopable (with a very slight jump at the point where the looping happens). This is primarily provided for real-time displays such as hyperwall systems. The 4 sequences are: all depth layers combined, shallow depths, middle depths, and deep depths.The second set is the same as the first set except that the layers are not composited over the background and instead include and alpha channel. The third layer is actually the frames that were used in the film \"Loop\" and consist of a large number of continuous, seamless frames. Each sequence is as before, all layers, shallow, middle, and deep layers all with alpha channels.The depth layers nominally correspond to the following ranges below sea level: shallow (0m - 600m), middle (1875m - 2500m), and deep (3000m - 4000m). These depths do vary with bathymetry. So, in areas where the sea floor is not very deep, these depths are scaled so that the flows do not interesct the sea floor or each other. || ", "hits": 115 }, { "id": 2915, "url": "https://svs.gsfc.nasa.gov/2915/", "result_type": "Visualization", "release_date": "2004-02-16T12:00:00-05:00", "title": "Blue Marble - A Seamless Image Mosaic of the Earth (WMS)", "description": "This spectacular 'Blue Marble' image is the most detailed true-color image of the entire Earth to date.

Albedo measures the proportion of incoming solar radiation reaching a surface that is reflected back to the atmosphere and to space. For an unchanging surface, albedo can vary somewhat, depending on the sky and atmospheric conditions. This image maps the white-sky albedo, which is the albedo under conditions of a uniform, dense cloud cover, in which downwelling light energy comes uniformly from all directions. The color bar indicates the albedo value ranging from 0.0 to 0.4 over the Earth's land surfaces. Areas colored red show the brightest, most reflective regions; yellows and greens are intermediate values; and blues and violets show relatively dark surfaces. White indicates no data is available. Typically, vegetated surfaces and water have low albedos, while soil and urban surfaces have somewhat higher values. Note that solar energy that is not reflected away from a surface is absorbed by that surface. Thus, albedo also provides information about the amount of energy absorbed by a surface. Since this energy serves to heat the soil and the air just above the surface, albedo is an important factor in weather and climate studies, and especially is important for modeling of weather and climate on scales of days to years.This image was produced using data composited over a 16-day period, from April 7-22, 2002. || ", "hits": 36 } ] }
