[californiadisasters] Report Critiques Lassen Park's Response To Reading Fire

Report critiques Lassen Park's response to Reading Fire

By Alayna Shulman | Redding Record-Searchlight
Posted January 30, 2013 at 6:53 p.m.

The National Park Service on Wednesday published a review of last summer's notorious Reading Fire in eastern Shasta County, saying Lassen Volcanic National Park officials were too shortsighted about the fire's growth potential and were overly focused on deflecting the criticism that grew along with the destructive 28,000-acre blaze.

The fire broke out on July 23 in Lassen Volcanic National Park and spread to the nearby forest, ultimately engulfing more than 28,000 acres after the park's superintendent made the controversial decision to let the lightning-sparked fire burn in its first two weeks to control undergrowth rather than immediately be extinguished.

Two weeks later high winds and unusually dry conditions caused the fire to balloon out of control, sparking fury from county residents and even legislators, who held a hearing at the state capitol in October on the fire controversy.

The fire also irked many residents because the park didn't tell them about it until around two weeks after it broke out, causing many to wonder what was causing the growing mass of smoke in the eastern sky.

In the Park Services's review of the fire, specialists from several agencies pointed out a handful of key flaws that should serve as "lessons learned" for the future.

According to the review, park officials should have:

- Planned for a worst-case scenario.

Analysts wrote that, while park officials felt the fire was manageable at first, "it became obvious that planning for a larger, more complex scenario would have been advantageous."

An unidentified park staff member was quoted in the review as saying he or she didn't "what-if" enough.

"I should have painted a darker picture," the employee said.

- Done a better job at informing the public.

Park officials didn't announce the fire to the public until after news of it was published in the Record Searchlight. The review of the fire says that lapse left many residents confused and scared, and also sparked rumors.

"Early and frequent communication with local communities, visitors, and partners is critical to reduce uncertainty, anxiety, and to quell rumors," the review reads. "Even if a fire never leaves the park, smoke impacts to neighboring communities need to be addressed and communicated early."

In addition, the review says the park needs to use consistent and current terminology so the public isn't misled about fires in the future, and its own employees need to be filled in ahead of time.

"Early fire information would have been helpful for background — before the media call," a park administrative assistant was quoted as saying in the report.

- Focused less on proving it was right to let the fire burn.

The writers of the review said the park needs to avoid the "tunnel vision of success" in the future and focus less on proving that a plan is working.

"Look for reasons to suspect that your plan might not work. Have a preoccupation with failure," the review reads.

In addition, it says, park officials need to be more open to the idea that they might not be right in their initial ideas.

"Fire managers are often 'salespeople' for what they think is the right thing to do...But fire managers need to find a balance between taking advantage of good opportunities to manage fire, and also playing 'devil's advocate' and arguing against fire at times."

- Paid more attention to the environment.

According to the review, the environmental conditions, including humidity and surface fuel amounts, changed between the time the fire started and the two weeks later when it jumped out of control.

"Recognizing these environmental changes over time and incorporating them into the fire management decision making are critical parts of the process," the review says.

- Been more flexible.

The review says future fires need a team that is more adaptable when things don't mesh with the initial plan.

"When the tempo or urgency of the fire changes, be willing to rapidly adjust and change any scheduled or structured logistical commitments, such as debriefings and feeding. Don't let what seems important trump what really is important," the review reads.

One crew leader was quoted in the review as saying, "We were working on a schedule at this point. But the fire wasn't working on that same schedule."

The review recommends that the park form an interdisciplinary support group to make risk assessments and estimates on operational needs that are then approved by the administrator.

The review also praised the park for several accomplishments, including its dedication to safety that resulted in zero fatalities and having an effective medical response plan, as well as a strong relationship with the Lassen National Forest.

[Geology2] Kansas and Oklahoma Lead Round 2

Kansas and Oklahoma Lead Round 2

Posted: 31 Jan 2013 05:51 AM PST

The release of new US Topo maps covering Kansas and Oklahoma usher in the second round of quadrangle revisions, updates and product improvement

Last September the U.S. Geological Survey marked the important milestone of completing the initial round of US Topo map production for the 48 contiguous states. The agency is continuing to improve the US Topo map product, moving into the second round of national map revisions. Hawaii is in production and Alaska production will start later this year.

The first two states to undergo this second US Topo map revision are Kansas and Oklahoma. The 1,403 quadrangles for Kansas and 1,032 quads covering Oklahoma replace the current US Topo maps, which will be added to the USGS Historical Topographic Map Collection. All of these maps are available for free download from The National Map and the USGS Map Store website.

Other new feature additions and improvements on the updated US Topo maps include:

Woodland tint derived from the National Land Cover Dataset
Fire stations
Hospitals
State and county boundaries
Forest service boundaries
Commercial roads in lieu of census roads
Forest Service roads and road numbers

"We are excited to begin our second part of our three-year mapping cycle," said Mike Cooley, the US Topo Project Manager. "During the past year, more than 3,000 US Topo maps were downloaded every day, and that number continues to increase."

US Topos are derived from key layers of geographic data found in The National Map, which delivers 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.

Future enhancements to the US Topo are scheduled to include additional tools and map content such as a shaded relief layer, updated structures, enhanced transportation, additional federal boundaries and Forest Service trails. Wyoming, which was added in the fall of 2012, also featured Public Land Survey System (PLSS). The USGS expects to produce more than 18,500 revised quadrangles annually. US Topo maps are updated every three years.

The new digital electronic topographic maps are delivered in GeoPDF image software format and may be viewed using Adobe Reader, available as a no cost download.

Re: [Geology2] Diatomaceous Earth In That Volcanic Province?

For what it's worth, the USGS does not specifically list any diatomite formation in Shasta County.

http://mrdata.usgs.gov/geology/state/fips-unit.php?code=f06089

I cannot help but wonder if the DE was misidentified and instead was a volcanic material.

Okay, Kimmer.. got it. Wherever these folks are digging must have been an ancient body of water. Volcanoes produce ash which is high in silicates. The ash falls into the water and the phytoplankton eat it, which produces those hard shells. The creatures die off after the food source is depleted, fall to the bottom. The cycle is repeated on a bell curve for population growth with each successive eruption. When the volcanoe goes dormant or becomes extinct, the diatoms die off, the water recedes and then you get a sedimentary bed of diatoms.

Think that's what you are asking.

Okay, that makes sense... at first glance it seemed out of place to have a sedimentary process occurring in the midst of all that volcanic activity but now I see.

[californiadisasters] Climate Change Impacts to U.S. Coasts Threaten Public Health, Safety and Economy

USGS-NOAA: Climate Change Impacts to U.S. Coasts Threaten Public Health, Safety and Economy

Posted: 28 Jan 2013 09:00 AM PST

View looking west along the New Jersey shore. Storm waves and surge cut across the barrier island at Mantoloking, NJ, eroding a wide beach, destroying houses and roads, and depositing sand onto the island and into the back-bay. Construction crews with heavy machinery are seen clearing sand from roads and pushing sand seaward to build a wider beach and protective berm just days after the storm. The yellow arrow in each image points to the same feature. ((High resolution image.

Science Feature: Start with Science to Address Vulnerable Coastal Communities.

According to a new technical report, the effects of climate change will continue to threaten the health and vitality of U.S. coastal communities' social, economic and natural systems.

The report, Coastal Impacts, Adaptation, and Vulnerabilities: a technical input to the 2013 National Climate Assessment, authored by leading scientists and experts, emphasizes the need for increased coordination and planning to ensure U.S. coastal communities are resilient against the effects of climate change.

The recently released report examines and describes climate change impacts on coastal ecosystems and human economies and communities, as well as the kinds of scientific data, planning tools and resources that coastal communities and resource managers need to help them adapt to these changes.

"Sandy showed us that coastal states and communities need effective strategies, tools and resources to conserve, protect, and restore coastal habitats and economies at risk from current environmental stresses and a changing climate," said Margaret A. Davidson of NOAA's Office of Ocean and Coastal Resource Management and co-lead author of the report. "Easing the existing pressures on coastal environments to improve their resiliency is an essential method of coping with the adverse effects of climate change."

A key finding in the report is that all U.S. coasts are highly vulnerable to the effects of climate change such as sea-level rise, erosion, storms and flooding, especially in the more populated low-lying parts of the U.S. coast along the Gulf of Mexico, Mid-Atlantic, northern Alaska, Hawaii, and island territories. Another finding indicated the financial risks associated with both private and public hazard insurance are expected to increase dramatically.

"An increase in the intensity of extreme weather events such as storms like Sandy and Katrina, coupled with sea-level rise and the effects of increased human development along the coasts, could affect the sustainability of many existing coastal communities and natural resources," said Virginia Burkett of the U.S. Geological Survey and co-lead author of the report.

The authors also emphasized that storm surge flooding and sea-level rise pose significant threats to public and private infrastructure that provides energy, sewage treatment, clean water and transportation of people and goods. These factors increase threats to public health, safety, and employment in the coastal zone.

The report's authors noted that the population of the coastal watershed counties of the U.S. and territories, including the Great Lakes, makes up more than 50 percent of the nation's population and contributed more than $8.3 trillion to the 2011 U.S. economy but depend on healthy coastal landforms, water resources, estuaries and other natural resources to sustain them. Climate changes, combined with human development activities, reduce the ability of coasts to provide numerous benefits, including food, clean water, jobs, recreation and protection of communities against storms.

Seventy-nine federal, academic and other scientists, including the lead authors from the NOAA and USGS, authored the report which is being used as a technical input to the third National Climate Assessment — an interagency report produced for Congress once every four years to summarize the science and impacts of climate change on the United States.

Other key findings of the report include:

Expected public health impacts include a decline in seafood quality, shifts in disease patterns and increases in rates of heat-related morbidity.
Changes in the location and the time of year when storms form can lead to large changes in where storms land and the impacts of storms. Any sea-level rise is virtually certain to exacerbate storm-surge and flooding related hazards.
Because of changes in the hydrological cycle due to warming, precipitation events (rain, snow) will likely be heavier. Combined with sea-level rise and storm surge, this will increase flooding severity in some coastal areas, particularly in the Northeast.
Temperature is primarily driving environmental change in the Alaskan coastal zone. Sea ice and permafrost make northern regions particularly susceptible to temperature change. For example, an increase of two degrees Celsius during the summer could basically transform much of Alaska from frozen to unfrozen, with extensive implications.
As the physical environment changes, the range of a particular ecosystem will expand, contract or migrate in response. The combined influence of many stresses can cause unexpected ecological changes if species, populations or ecosystems are pushed beyond a tipping point.
Although adaptation planning activities in the coastal zone are increasing, they generally occur in an ad-hoc manner and are slow to be implemented. Efficiency of adaptation can be improved through more accurate and timely scientific information, tools, and resources, and by integrating adaptation plans into overall land use planning as well as ocean and coastal management.
An integrated scientific program will reduce uncertainty about the best ways coastal communities can to respond to sea-level rise and other kinds of coastal change. This, in turn, will allow communities to better assess their vulnerability and to identify and implement appropriate adaptation and preparedness options.

This report is available online.

NOAA's mission is to understand and predict changes in the Earth's environment, from the depths of the ocean to the surface of the sun, and to conserve and manage our coastal and marine resources. Join NOAA on Facebook, Twitter and other social media channels.

As a former pet store hand, we used diatomaceous earth to polish the water in fish tanks. Sometimes what we used was the actual dead diatoms (single celled algae aka phytoplankton) which form organically. But other times, we used Bentonite clay, which is a residue leftover from ancient volcanoes and is pumice-like on a microscopic level and neutrally sound in water.

Hope that helps...

From the pages of the Redding Record-Searchlight 50 years ago:

1963: Diatomaceous earth would be mined near Lake Briton by a Covina company.
The D and F Mining Co. bought rights to 1,200 acres of diatomaceous earth.
The company was the only bidders when the U.S. Forest Service offered the deposit for sale.

Re: [Geology2] Diatomaceous Earth In That Volcanic Province?

As a former pet store hand, we used diatomaceous earth to polish the water in fish tanks. Sometimes what we used was the actual dead diatoms (single celled algae aka phytoplankton) which form organically. But other times, we used Bentonite clay, which is a residue leftover from ancient volcanoes and is pumice-like on a microscopic level and neutrally sound in water.

Hope that helps...
