The Federal Emergency Management Agency (FEMA) today released Preliminary Flood Insurance Rate Maps (FIRMs) for Middlesex and Monmouth Counties that reflect the latest refinements to the ongoing analysis of flood hazards. This release is the next step in the coastal Flood Insurance Study update. The Preliminary FIRMs replace the Preliminary Work Maps for Middlesex and Monmouth Counties that were released in June/July of 2013 as an interim product.Language English

Evaluations of water nutrient ratios suggest that concentrations of a class of cyanobacteria toxins (cyanotoxins), called microcystins, tended to decrease as the total nitrogen to total phosphorus (TN:TP) ratio increased.
Nitrogen addition and phosphorus removal treatments were used to control nutrient ratios in confined experimental chambers in Willow Creek Reservoir, Ore., over two consecutive summers.
Two scientific articles on this research, recently published in the scholarly journal Lake and Reservoir Management, were completed as a joint partnership between the University of Idaho and the U.S. Geological Survey. The study supports previous work done on nutrient ratios and microcystins. The articles, entitled "Experimental manipulation of TN:TP ratios suppress cyanobacterial biovolume and microcystin concentration in large-scale in situ mesocosms," and "Experimental additions of aluminum sulfate and ammonium nitrate to in situ mesocosms to reduce cyanobacterial biovolume and microcystin concentration," are available online.
"This does not necessarily mean that increasing nitrogen in a lake will decrease cyanotoxins," said USGS scientist Ted Harris. "This was a study done in one location, and warrants further research."
This case study suggested that a TN:TP ratio of 75:1 or larger resulted in the growth of green algae instead of toxic cyanobacteria. Toxic cyanobacteria can produce toxins such as microcystins which can be harmful to aquatic life, terrestrial animals, and humans. Cyanotoxin exposure has led to illness in wildlife, livestock, and humans and can result in death in severe exposure cases.
Results from this research could help manage cyanobacteria toxin production; however these approaches need to be studied more extensively in whole-lake settings to fully understand the implications of using these approaches to control cyanobacteria toxin production balanced against other potential environmental harm and socio-economic conditions.

FEMA Extends Disaster Assistance Deadline for Illinois Tornado Survivors: FEMA says let us know you need help
SPRINGFIELD, Ill. — At the request of the state of Illinois, Nov. 17 tornado survivors now have until Monday, Feb. 3 to apply to FEMA for disaster assistance.

PASADENA, Calif. — Earthquake activity in the New Madrid Seismic Zone in the central United States does not seem to be slowing down. In a new study published in the journal "Science," seismologists Morgan Page and Susan Hough of the U.S. Geological Survey investigate whether current quakes in the region could be aftershocks of large earthquakes that occurred 200 years earlier.
Using extensive computer modeling of aftershock behavior, they show that the dearth of moderate (Magnitude 6) earthquakes following the series of large earthquakes in 1811-1812, combined with the high rates of small earthquakes today, is not consistent with the long-lived aftershock hypothesis.
A debate has swirled in recent years, fueled in part by past studies suggesting that continuing New Madrid seismic activity could be the tail end of a long-lived aftershock sequence following the 1811-1812 earthquakes. If modern activity is an aftershock sequence, the argument goes, then there is no evidence that stress is currently building in the zone. Instead, Page and Hough conclude that the current level of activity must be the signature of active, ongoing processes that continue to generate stress in the region –stress that we expect will eventually be released in future large earthquakes. In other words, the New Madrid Seismic Zone is not dead.
The New Madrid Seismic Zone in the central United States produced 4 large earthquakes with magnitudes upwards of 7 over the winter of 1811-1812. Over the last two centuries, small quakes have continued to occur in the zone at a higher rate than elsewhere in the central United States. Geologic evidence also shows that large earthquake sequences occurred there in about 1450 A.D. and 900 A.D.Recent earthquakes in the New Madrid Seismic Zone (CEUS-SSC catalog, 1990-2008). (Larger image) A timeline of earthquakes in the New Madrid Seismic Zone (top) differs significantly from a typical aftershock sequence (bottom). A new study shows that earthquakes occurring today in the region are not aftershocks of the 1811-1812 earthquakes. Rather, they are evidence that stress is continuing to accumulate.

The USGS, in cooperation with other Federal agencies, has posted new Idaho US Topo quadrangles (1,193) and New Mexico quads (1,980 maps) which include Public Land Survey System (PLSS). These are added to the growing list of states west of the Mississippi River to have PLSS data added to US Topo maps.
"It is a privilege to support production of the US Topo maps, as I am an extensive user of these products,” said Kristin Fishburn, a geographer with the USGS. “The capability to turn layers on and off combined with the continuous enhancements in content makes the maps particularly useful for a recreational user. I'm excited to peruse the new Idaho and New Mexico maps."
The PLSS is a way of subdividing and describing land in the United States. All lands in the public domain are subject to subdivision by this rectangular system of surveys, which is regulated by the U.S. Department of the Interior. Other selected states will begin getting PLSS map data during the next respective revision cycle.
The new design for US Topo maps improves readability of maps for online and printed use, while retaining the look and feel of the traditional USGS topo map. Map symbols are easy to read when the digital aerial photograph layer imagery is turned on.
Other re-design enhancements and new features:
- New shaded relief layer for enhanced view of the terrain
- Military installation boundaries, post offices and cemeteries
- New road classification
- A slight screening (transparency) has been applied to some features to enhance visibility of multiple competing layers
- New PDF legend attachment
- Metadata formatted to support multiple browsers
US Topo maps are created from geographic datasets in The National Map, and deliver visible content such as high-resolution aerial photography, which was not available on older paper-based topographic maps. The new US Topo maps provide modern technical advantages that support wider and faster public distribution and on-screen geographic analysis tools for users.
The new digital topographic maps are PDF documents with geospatial extensions (GeoPDF®) image software format and may be viewed using Adobe Reader, available as a no-cost download.
These new quads replace the first edition US Topo maps for Idaho and New Mexico. The replaced maps will be added to the USGS Historical Topographic Map Collection which are also available for free download from The National Map and the USGS Map Locator & Downloader website.
US Topo maps are updated every three years. The initial round of the 48 conterminous state coverage was completed in September of 2012. Hawaii and Puerto Rico maps have recently been added. More than 400 new US Topo maps for Alaska have been added to the USGS Map Locator & Downloader, but will take several years to complete.

The PLSS information shown on these maps is for general reference purposes only, and should not be used to determine legal boundaries or land ownership. The Bureau of Land Management (BLM) is the authoritative source for PLSS information at the federal level, and the US Topo representation is derived from BLM GIS data files. The management of these data is not completely uniform throughout the country." (Larger image)
