I. AbstractOn 13 November 1985, after almost a year of increased activity, Nevado del Ruiz volcano in Colombia’s Cordillera Central range of the Andes erupted violently. Pyroclastic flows swiftly melted glacial ice and snow to generate lahars (volcanic mudflows) that swept down river valleys through urban and rural areas tens of kilometers from the volcano. Despite several hours of warning and potential evacuation time, lahars caused more than 23,000 casualties, largely due to an uninformed populace and ineffective emergency protocols. Since the event, Colombian geologists, emergency planners, and elected officials have greatly improved community education and emergency evacuation systems near multiple active volcanoes and these new systems have proven highly effective during subsequent events.
As an opportunity to learn from the Nevado del Ruiz disaster and the subsequent planning by Colombian authorities, a ten-member delegation from Washington State representing federal, state and local emergency managers, planners, and scientists visited Colombia in August 2013 as part of a bi-national exchange with their Colombian counterparts. Participants viewed effects of the 1985 eruption and the Colombians’ more recent mitigation efforts. The most striking lessons learned by U.S. participants concerned the importance of pre-designated and well publicized evacuation routes, information hubs, community involvement in all aspects of planning and preparedness, and frequent exercising of notification devices and evacuation. Subsequently, nine Colombians visited Washington State in September 2013 to learn from our efforts in volcano preparedness and mitigation.
Using new knowledge about effective eruption preparations, U.S. bi-national exchange participants are expanding efforts for preparedness and mitigation in communities at risk. Some examples include: preliminary development of a state-wide volcano awareness/preparedness plan in Washington; upgraded Pierce County evacuation maps; information kiosks placed around the volcano; development of new Mount Rainier Volcano Hazards website (http://www.piercecountywa.gov/activevolcano); local FEMA-USGS Volcano Crisis Awareness trainings and plan exercises; and almost two dozen public presentations during the 2014 Volcano Preparedness Month.
The corresponding author would like to thank the following individuals with the National Park Service and Department of Interior for approving travel and facilitating this life-changing event: Randy King, Donna Rahier, Roger Andrascik, Darin Swinney, Barbara Samora, Celeste Gray, Sara Jivanjee, Dee Sousa, April Brooks and Paul Kemppainen. Thanks to Tom Pierson at the USGS for providing background information. We also thank the tremendous work by USGS/CVO Scientist-in-Charge John Ewert for arranging all aspects of the trip (but staying home to let someone new go!). The Colombians were truly gracious hosts and we acknowledge the numerous individuals in Colombia for safely getting us around, sharing their stories and hospitality, and showing us their beautiful country.

A second Bi-National Exchange is being planned for Summer 2015.
Mount Rainier (4,392 m) in Southwest Washington State and Nevado del Ruiz (5,390 m) in the Cordillera Central range of Colombia are both andesitic stratovolcanoes with similar geography and hazards. Both volcanoes have extensive populations at their bases and have had histories of major lahars.
In November 1984, Nevado del Ruiz began showing increasing seismicity. By February 1985 under increasing activity, geologic investigations began. On September 11, 1985, a strong ash eruption occurred. In October 1985, the activity decreased while a new hazard map showed the risk of lahars as “high” to downstream low-lying communities. This map was generally dismissed as being too alarming. In November, activity increased again.
On November 13, 1985, the following events occurred at Nevado del Ruiz:• 3:06 PM: Steam eruption.• 9:08 PM: Dacitic tephra eruption, 30 km high eruptive column (VEI = 3). - Pyroclastic flows caused 4 lahars. - 17 km2 snow and ice melted during the eruption. - 2x107 m3 meltwater produced within 30 minutes of the eruption.• 10:30 PM: Lahar reaches Chinchiná (west of Nevado del Ruiz) (1,800 casualties).• 10:45 PM: Armero (east of Nevado del Ruiz) warned to evacuate.• 11:35 PM: Lahars reach Armero (21,000+ casualties).
Following the eruption, extensive humanitarian efforts occurred to save as many victims as possible. Additionally, Colombians undertook numerous efforts to learn from the disaster and prepare for future geologic events in their country.

LAVA FLOW LAHAR MUDFLOWS
LANDSLIDEAre You Ready for An Eruption?MOUNT RAINIER IS AN ACTIVE VOLCANO
Mount Rainier is much more than a mountain in the sky. Constructed of hundreds of lava flows, and capped by as much glacier ice as all other Cascade volcanoes combined, Rainier’s steep rubbly slopes and abundant water make it prone to landslides and lahars (volcanic mudflows), especially during eruptions. Lahars are the biggest hazards to the area. Scientists and emergency officials watch and warn. Do your part by being prepared.
• Look at the map. Assess the hazards where you live, work, and commute.• Make a plan. Identify lahar evacuation routes and shelter above valley floors.• Assemble emergency supplies and a plan to reunite. • Share your plans with family, neighbors and friends.
LIVE SAFELY NEAR MOUNT RAINIER
STAY INFORMED: LISTEN TO OFFICIAL SOURCES
• Emergency broadcasts.• Pierce County ALERT.• All Hazards NOAA Weather Radio.• 511 emergency travel information.• USGS Volcano Notification Service lists alert levels.• Outdoor sirens in some communities.
WHEN A LAHAR WARNING IS ISSUED, MOVE OFF THE VALLEY FLOOR
• Evacuate by vehicle or on foot to high ground 50 feet or more above the valley floor. • If you are safe from lahars and ash is falling, seek shelter in a building or vehicle.
Ready. Set. Go!
While an eruption or lahar might not happen in our lifetime,
being prepared is our best defense.

The Colombian people experienced a terrible tragedy during the 1985 eruption of Nevado del Ruiz. The event was a wake-up call for a largely ineffective emergency preparedness culture in the country. Since the 1985 event, the country has taken great strides in improving its emergency preparedness. With the exception of Mount St. Helens in 1980, the United States has not experienced an event like that in Colombia and has little to no human history about the effects of volcanic eruptions. By using lessons learned from the Colombian people, the United States is able to glean important information from the Colombian emergency preparedness plans and actions. We can also use stories from survivors and photos of devastated areas to prepare Americans for a future eruption of Mount Rainier. Products like the information kiosks (below) that are being placed across Pierce County, as well as public presentations and information dissemination during volcano preparedness months will enlighten communities at risk about the hazards from future events at Mount Rainier and other volcanoes in the Pacific Northwest.
“It’s not enough to tell people to evacuate; You have to tell them
where to go.”- Armero Survivor
“(A lahar event) may not happen in our lifetimes, our children’s
lifetimes, or even our grandchildren’s lifetimes, but we owe it to our
community to develop a culture of preparedness.”- Armero Survivor
Effective warning systems need to be in place.
BELIEVE it can happen.
Affected populations need to be trained in what to do when a warning sounds. Then they need to practice
doing it regularly.
Education from early childhood is very important.Preparedness needs to begin at an early age.
Known local officials are more often trusted than unknown scientists or bureaucrats.
It is human nature to wait until the last minute before taking action.
Collective memories about disasters are short.(1985 disaster was a repeat of those in 1595 and 1845)
Know your hazards. Know how to prepare. Know how to respond. Know where to get reliable information.
ACT when the event happens.
Community building after a disaster is challenging. Life is going to be different after a disaster.
The “Ghost of Armero” is as a powerful symbol for the importance of working together. Colombians are determined to never let a similar event happen again.
A few dedicated individuals can effect great change.There is great value in scientists and emergency
officials talking to local people and gaining their trust.
Everyone has a role in preparedness: Scientists, officials, and people at risk.
Rebuilding a community is much more than fixing the infrastructure: it’s important to facilitate rebuilding in a way that does not exacerbate the original problem.
Left: SGC Geologist Marta Calvache asks two children in Nuevo Rio Claro about evacuation routes; The children knew exactly where to go when the alarm sounded. Colombian children are taught from an early age about the effects of volcanic eruptions and how to properly train for an eruption and what to do.
Right: A Colombian survivor (in red) relates a story about surviving the event and losing his family members (mother pictured). While this event is fresh in the minds of Colombians, most of the population of the United States has never experienced an event like that in Colombia.
Right: Bi-National participants look over a map of the lahar hazards from Nevado del Ruiz near the Rio Azufrado on the peak’s east side. Bi-National exchange participants learned how Colombian scientists, political officials, and the public work together to increase emergency preparedness.
Right: Lahar hazard map for Nevado del Ruiz. The original map created just prior to the event was dismissed as being “too alarming.” However, Lahars from the 1985 event followed paths shown in the hazard map almost perfectly. Knowing hazards is the first step to preparing and having a proper response when an event happens.
Left: The buried first floor of Armero’s community hospital is a stark reminder of the power of the 1985 lahars. The former site of Armero has been left as a memorial to the disaster and nature has taken over the remains. The site serves as a powerful reminder of the event and the lessons learned from the disaster.
Right: Walking amongst the remains while hearing stories of the night of the lahars is an indescribable experience. There are many stories of victims that were killed by panic-stricken motorists just trying to leave the city. Warnings were unheeded and lead to an atmosphere of disbelief as the waves of lahars entered the city the night of November 13, 1985.
Right: Remains of a church in Nuevo Rio Claro abandoned after lahars of November 13. The church stands as a reminder of the event and has been left abandoned since. It also serves as a reminder about the threat of future lahars and building in areas delineated on hazard maps as “high risk”.
Right: USGS and SGC geoscientists at the Mount St. Helens Visitor Center in September, 2013. The scientific community is a vital component of an effective emergency preparedness plan. Information compiled by scientists needs to be disseminated to communities at risk in language and with context such that non-scientists can understand and be motivated to action.
Left: The mayor of Armero-Guayabal (center) talks to Scott Beason (left) and translator (right) about the disaster. During the 1985 event, victims were vulnerable to accepting information from the most convincing speakers rather than from scientifically-knowledable authorities.
Right: Oblique aerial view of Armero immediately after the event. Armero was completely destroyed in the event. Even as pumice was falling and lahars were entering the town, victims refused to believe or understand what was happening.
Right: Most of the surviving residents of Armero moved north to the city of Armero-Guayabal (“New Armero”). Some survivors moved to other locations in Colombia. One thing was common to all survivors: Life would never be the same again.
Left: Example of the volcano warning system in Nuevo Rio Claro. The system is redundant in three ways: it can be activated by satellite, cellular phone, and manually by a button at the base of the structure. Bi-National exchange participants from the United States were surprised by the availability of communication in Colombia, especially considering its rugged topography.
Right: Bridge crossing the Rio Claro near Nuevo Rio Claro. Structures like this allow low-lying populations to cross physical barriers and get to safe locations.
