Today, we're discussing the monumental impact of the Alto Mayo earthquakes in 1990 and 1991. Can anyone tell me what an earthquake is?
It's when there are sudden shakes of the ground because of shifting tectonic plates.
Exactly! These earthquakes measured 6.2 on the Richter scale, resulting in tremendous destruction. How many homes were impacted?
Around 6,000 homes were damaged or destroyed.
Correct. This event led to the tragic loss of approximately 70 lives. Let's remember this with the acronym DIE: Damage, Injuries, and Economic loss.
Now, how should communities approach recovery after such disasters? What did Practical Action focus on?
They emphasized long-term reconstruction rather than just short-term relief.
Exactly! This approach is part of the 'Build Back Better' initiative. How can rebuilding be better than before?
By incorporating earthquake-resistant materials and techniques!
Right! They moved away from adobe and rammed earth. Let's use the mnemonic RISE: Rebuild with Innovative Shelter Engineering for impact.
Let's dive into the quincha construction technique that replaced traditional methods. Does anyone know what materials are used in quincha?
Timber frames and woven cane!
Perfect! This method improves resilience and lowers repair costs significantly. Remember the phrase LOWER: Low-cost Options with Effective Resilience.
Why was it chosen over adobe?
Because quincha provides better earthquake resistance and uses local resources, fostering community involvement.
Finally, let’s discuss the broader impacts of these recovery efforts. How did the economy change post-recovery?
There was a rise in community participation and housing stability.
Excellent! By 1994, about 558 improved quincha houses were built. This sparked widespread community involvement, which can be summed up as GROW: Greater Resilience, Opportunities, and Well-being.
So, the techniques not only helped rebuild but also empowered the community?
Exactly! Empowerment through participation is key for sustainable recovery.
In Alto Mayo, quakes did shake, but with quincha, they’ll rebuild, no mistake!
Once upon a time, in the shaking lands of Alto Mayo, a wise builder taught the townsfolk to weave their homes with strength using timber and cane. After the quake, they stood tall, thanks to their collective effort.
Remember 'RISE': Rebuild with Innovative Shelter Engineering for impact.
DIE: Damage, Injuries, and Economic loss, to recall the earthquake's aftermath.

A region in Peru significantly impacted by earthquakes in 1990 and 1991.
A construction technique using timber frames and woven cane, providing improved earthquake resistance.
An approach focusing on long-term recovery and resilience in the aftermath of disasters.
A traditional building method using natural raw materials, which was less effective in earthquake-prone areas.
This section discusses the impact of the 1990 Alto Mayo earthquakes and the subsequent recovery efforts, focusing on innovative construction methods aimed at improving earthquake resilience.
The 1990 Alto Mayo earthquakes significantly affected the region, resulting in loss of life and destruction of homes. Through the work of various organizations, a recovery model was implemented that favored quincha construction techniques over traditional adobe, which improved resilience and affordability. The outcomes showed a surge in community participation and a noteworthy rise in housing stability in the region.
The Alto Mayo region experienced significant devastation from earthquakes on May 29, 1990, and again in 1991, both registering at 6.2 on the Richter scale. The first earthquake resulted in approximately 70 fatalities, 1600 injuries, and damaged or destroyed about 6,000 homes. Following these disasters, recovery efforts spearheaded by Practical Action focused on long-term reconstruction rather than short-term relief.
An essential part of the recovery involved the reevaluation of construction techniques. Traditional methods, such as rammed earth and adobe, were deemed less viable due to their vulnerability to earthquakes. Instead, quincha construction, a technique utilizing timber frames and woven cane, was promoted due to its improved earthquake resistance and local material availability. This method not only reduced costs significantly (about $1,300 for a 30 square meter house compared to $5,400 for brick structures) but also facilitated community participation, with local residents getting trained in construction methods.
Key modifications included the integration of concrete foundations, which strengthened the structure, and lightweight roofing materials, reducing hazards from falling debris during seismic events. The outcome of these initiatives not only led to an increase in earthquake-resistant homes in Alto Mayo but also inspired a cultural shift towards sustainable building practices and reinforced local capacities.
