Ever notice that wildfires seem to have generic names like the Valley Fire or seemingly random names like the Waldo Fire and wonder where wildfires get their names? Here at RedZone we took a look what the standards are for the wildfire naming criteria and the top names used historically in our wildfire database.
With the duties assigned to fire agencies becoming more daunting as the population continues to grow, and climatic conditions favor worse fire behavior, the service has adopted GIS as a means to combat these ever changing factors. In this blog, I briefly touch on some of the aspect that GIS software programs have been implemented in the fire service to help mitigate some of the issues related to the disasters they face on a daily basis.
NOAA has released the 2019 Hurricane Season Outlook. Here is a summary of what has been mentioned in the release. Based on this report, its beginning to look similar to the 2018 hurricane season.
Severe weather is upon us in the United States with damaging tornadoes hitting the southern states in late January and late February. One EF4 tornado also tore through Alabama and Georgia in early March, the worst of the roughly 100 reported tornado total so far in 2019. As we move into the spring and summer months, conditions historically become more volatile. Specifically from March to June, the highest chance of severe weather spreads north and east across the Plains, the Midwest, and Southeast. Like Hurricanes and Wildfires, Tornadoes have a peak season too.
This barrier island along the gulf coast was home to millionaires and large elaborate mansions sprawling the coastline. The highest point of elevation being 8.7 feet above sea level, the community is ripe for devastation from a hurricane.
In the year 1900, this area was struck with a horrendous hurricane that would ultimately destroy the entirety of the community and kill an estimated 6,000 to 8,000 people.
When most people think of natural disasters, the first thing to come to mind is not likely flooding. However, flooding is the most common natural disaster. Flooding occurs in all 50 states, accounts for 40% of natural disasters, averages 5 billion dollars in damage each year, and claimed an average of 75 lives per year over the last 30 years.
It seems strange to be talking about weather events that peak in the summer, like tornadoes, while we still have massive winter storms impacting much of the Northeastern United States. However, now is typically when we start shifting our focus onto the weather incidents of the upcoming summer season. The end of February is when tornado season starts to ramp up, and will typically peak around mid-June.
The morning of November 30th, 2018, at 8:29 AM local time, a 7.0 magnitude earthquake shook the city of Anchorage, Alaska. The origin of the quake was 7 miles north of the city, resulting in the residents of Anchorage feeling the full intensity of this earthquake. Luckily, the epicenter was at a depth of 27 miles into the Earth’s crust. The depth of the origin allowed for the seismic energy of the earthquake to diminish slightly while making the 27-mile vertical journey before wreaking havoc on the surface.
The Shake Map shows the extent and magnitude in the surrounding areas during the 7.0 earthquake near Anchorage, Alaska,.
Upon reaching the surface, the resulting damages included widespread power outages, severe damage to roadways and other transportation infrastructure, and internal damage to residential and commercial structures. Immediately after the quake hit, the USGS released figures that contained frightening numbers depicting the probability of economic losses. The figure below shows that, according to the USGS predicted losses, there is a 35 percent chance of damages ranging from $100 million – $1 billion. The data goes on to show that there is a 20 percent chance that the economic losses could very well total over one billion dollars!
Immediately after the quake and ongoing through this week, the area continues to be inundated with relentless aftershocks that still hold immense power. As of this morning, the area has been the recipient of over 2,700 aftershocks and tremors, ranging in magnitude from 1 up to 5. There is still potential for an aftershock to be nearly as powerful as the original incident itself, which would cause even more damage during the recovery process.
In 1964, Anchorage fell victim to a 9.2 magnitude quake that caused damage to such an extent that certain parts of the city were unrecognizable. This earthquake killed 15 people during the event and another 124 from the resultant tsunami. Only one earthquake in recorded history has been more powerful (9.5 magnitude in Chile 1960). In the wake of this devastating event, the changes to the building codes may have resulted in massive economic saves in relation to building loss during this most recent quake. One of the key ideas that resulted from the research in the aftermath of the 9.2 magnitude event was the concept of integrating ductility into modern architecture and design. Ductility is the ability to bend without breaking, which helps absorb some of the seismic motion during an earthquake. One way this could be achieved in the case of concrete structures would be ensuring the right amount of steel reinforcement is located in the correct areas of the structure. This is just one example of the engineering constructs resulting from the Earthquake Hazard Reduction Act of 1977, which was sparked by the enormous 1964 earthquake.

RedZone Senior Wildfire Liaison Doug Lannon attended The Thomas Fire Retrospective Report discussion was held at 5:30 pm on Wednesday, October 17th, 2018 at the Montecito Fire Protection District (FPD) Headquarters located at 595 San Ysidro Road in the community of Montecito, California. These are some key points that Doug took away from the discussion.
The presentation was sponsored by the Montecito FPD Board of Directors and Montecito Fire Chief Chip Hickman. The discussion was led and facilitated by Dr. Crystal Kolden, Director of the Pyrogeography Lab and Associate Professor of Fire Science for the University of Idaho, College of Natural Resources. Dr. Kolden presented the history of the community of Montecito’s Wildland Fire Program Policy, and actions from when it was first discussed after the devastating Painted Cave Fire which occurred in 1990 near Goleta, and was then instituted after the even more destructive Tunnel Fire which occurred in 1991 in the Oakland Hills. The program has been enthusiastically supported and continued to date by the Montecito FPD Board of Directors, the Montecito FPD personnel, and the Citizens of Montecito, due to a highly effective and efficient Community Fire Protection and Fire Prevention Education and Partnership Program. Dr. Kolden also discussed the types of mitigation strategies that have been successful in recent wildfires, both for individual homeowners and for communities.
The map above shows the new acreage that was burned at the end of each day.
Montecito was just one of several cities and communities that were threatened and received significant impact to residential and commercial properties during the 2017 Thomas Fire. However, compared to other communities impacted by the Thomas Fire, the community of Montecito suffered only a fraction of the damage that other communities suffered during the Thomas Fire. Montecito’s wildland fire program has spent the last 20 years developing a set of systems to combat the threat of wildfire. These systems include implementing new stringent building codes and architectural guidelines, creating a hazardous fuel treatment network across the northern portion of the community, developing a pre-attack plan to disseminate critical fire ground information to mutual aid resources, developing partnerships within the community and with adjacent agencies, and building a community education program that facilitates a positive working relationship with the community. These systems were successfully deployed to support structure defense actions by the more than 500 firefighters assigned to Montecito the morning of December 16th, 2017. The Community Education and Partnership Program include: defensible space surveys and inspections, neighborhood chipping days, preparedness planning, pre-attack zones and homes, voluntary and mandatory evacuation zones and trigger points, widening roads, hardening structures, and ornamental shrubbery around structures, etc. In part, due to the effectiveness of the systems, only minimal structure loss and damage occurred, but most importantly, no lives were lost or serious injuries occurred prior to and during the fire fight. A post-fire assessment found that the seven primary residences destroyed during the Thomas Fire lacked defensible space, lacked safe access due to narrow roads or no turnarounds for fire apparatus, were constructed of flammable construction materials, or were situated where gaps existed in the fuel treatment network. Forty other properties received varying degrees of damage to outbuildings, fencing, ornamental shrubbery, etc.
Depicted in the image above is a well defined fuel break similar to the examples mentioned in this blog topics.
In retrospect, the Thomas Fire demonstrated how proactive actions implemented by the District and the community in the past 20 years contributed to the successful defense of the community during the Thomas Fire. Post-fire, Montecito still has unburned fuel in smaller enclaves within the community and within the 2008 Tea Fire and 2009 Jesusita Fire burn scars. These open space areas still have the potential to support smaller, more localized wildfires. Given the favorable climatic conditions of the Central Coast, over the next 10-20 years, vegetation in the footprint of the Thomas Fire will be able to support wildfire again. There is much opportunity for the District to use the Thomas Fire burned area to continue to expand and improve upon the existing fuel treatment network. Treating vegetation as it regrows will be less labor intensive and less costly than in the past. Leveraging community partnerships, improving the use of technology to support fire operations, modifying defensible space fire codes, and continuing the wildland fire safety and education of the community are critical steps for the District in the upcoming years as they prepare for the inevitable next wildfire. We know it’s coming, it’s just a matter of when!
