Yosemite Hantavirus: U.S. Officials Send Warnings To Dozens Of Countries


huffingtonpost.com - September 5th, 2012 - Ronnie Cohen

U.S. health officials have sent warnings to 39 other countries that their citizens who stayed in Yosemite National Park tent cabins this summer may have been exposed to a deadly mouse-borne hantavirus, a park service epidemiologist said on Tuesday.

Of the 10,000 people thought to be at risk of contracting hantavirus pulmonary syndrome from their stays in Yosemite between June and August, some 2,500 live outside the United States, Dr. David Wong told Reuters in an interview.

Wong said U.S. Department of Health and Human Services officials notified 39 countries over the weekend, most of them in the European Union, that their residents may have been exposed to the deadly virus.

Faulty Computer Modeling Caused San Onofre Nuke Equipment Problems

NRC officials give their first public account of their probe into the shuttered plant's problems.

Faulty computer modeling caused the equipment problems that are expected to keep the San Onofre nuclear plant dark through the summer, federal regulators said Monday.

Officials from the U.S. Nuclear Regulatory Commission gave their first public account of the initial findings of their investigation into the plant's problems at a meeting in San Juan Capistrano.

What they did not give was any indication of how long the plant is likely to remain out of service, saying there are still questions plant operator Southern California Edison needs to answer and more inspections the NRC must do.

U.S. seismologists currently testing new warning system

by Andrew Pinsent - CBC News - May 5, 2012

Scientists in the United States have been testing an advanced tsunami warning system using GPS data, combined with traditional seismology networks, to attempt to detect the magnitude of an earthquake faster so warnings of potential tsunamis can get out to potentially affected areas sooner.

The prototype is called California Integrated Seismic Network (CISN), and is a collaboration between the United States Geological Survey (USGS) and The Gordon and Betty Moore Foundation, whose focus is on environmental conservation.

California Nuclear Plant Shut Indefinitely Amid Hunt to Find Cause of Problems

submitted by Janine Rees

      

The power plant has been shut down since this winter, when a small amount of radioactive gas escaped.

CNN - April 6, 2012
STORY HIGHLIGHTS
  • Anti-nuclear activists warn of a potential environmental catastrophe
  • The San Onofre nuclear plant has been shut down since radioactive gas escaped
  • Officials have said there's no harm to the public health, but can't identify problem's cause
  • The head of the NRC says the plant won't restart until a cause and plan is put forward

(CNN) -- A large Southern California nuclear plant is out of commission indefinitely, and will remain so until there is an understanding of what caused problems at two of its generators and an effective plan to address the issues, the nation's top nuclear regulator said Friday.

Cracked Steam Generator Tubes at San Onofre

by Dave Lochbaum - allthingsnuclear.org - March 27, 2012

Leaks in San Onofre Unit 3 and Unit 2:

On February 18, 2011, operators restarted the Unit 3 pressurized water reactor (PWR) at the San Onofre nuclear plant in southern California following its sixteenth refueling outage. During the outage, workers replaced both of the reactor’s steam generators, which are large cylindrical containers that are partially filled with water.

At 3:05 pm on January 31, 2012 – less than a year later – radiation alarms alerted the control room operators that water was leaking through one or more of the tubes in one of the steam generators on Unit 3. They estimated the leak rate to be 82 gallons per day.

Water Scarcity in California's Bay-Delta Necessitates “Hard Decisions”

Homeland Security News Wire - March 30, 2012

Simultaneously attaining a reliable water supply for California and protecting and rehabilitating its Bay-Delta ecosystem cannot be realized until better planning can identify how trade-offs between these two goals will be managed when water is limited, says a new report from the National Research Council.  Recent efforts have been ineffective in meeting these goals because management is distributed among many agencies and organizations, which hinders development and implementation of an integrated, comprehensive plan.  Additionally, it is impossible to restore the delta habitat to its pre-disturbance state because of the extensive physical and ecological changes that have already taken place and are still occurring, including those due to multiple environmental stressors.

California Struggling to Prepare Quake Early Warning System

The state spends a fraction of what countries like Mexico and Japan spend on their systems. One reason for the lack of interest, experts say, is that California has not experienced a catastrophic quake in more than a century.

Reframing Resilience

 


First, there is great value in a systems approach as a heuristic for understanding interlocked social-ecological-technological processes, and in analysis across multiple scales. Yet we need to move beyond both systems as portrayed in resilience thinking, and the focus on actors in work on vulnerability, to analyse networks and relationships, as well as to attend to the diverse framings, narratives, imaginations and discourses that different actors bring to bear.

Resilience Alliance

There are many definitions of resilience from simple deterministic views of resilience anchored in Newtonian mechanics to far more dynamic views of resilience from a systems perspective, including insights from quantum mechanics and the sciences of complexity.  One baseline perspective of resilience sees it in terms of the viability of socio-ecological systems as the foundation for sustainability.  For those that are ready to look beyond resilience as the ability to return to the "normal state" before a disaster, take a look at:
