This threat is radically increased due to the lack of structural integrity of buildings in the region, especially in densely populated areas, and inadequate planning as to where buildings were constructed. It is critical that states such as Oregon and Washington retrofit or reconstruct existing buildings to reduce the risks associated with a potential major mega-thrust earthquake generated by the Cascadia Subduction Zone. Portland, Oregon’s largest city, is currently one of the most vulnerable cities in the US to a major earthquake. If a large earthquake struck the Pacific Northwest, Portland would be greatly affected because most of the buildings within the city were constructed before the state-wide building codes were enacted in 1973, and well before the first state wide seismic building codes (enacted in 1993). In an ideal scenario, reconstructing every building to be earthquake safe and up to code would be the plan. However, reconstructing the buildings of an entire city would be expensive, complicated, and extremely time consuming. For those reasons, this study focused on different retrofitting techniques and their costs, and the necessity for certain buildings to be reconstructed. Retrofitting costs were compared to the cost of demolition and reconstruction of old buildings, in order to determine the most economically viable course of action for preventing loss of life and minimizing structural losses in Oregon. Buildings are not the only type of infrastructure at risk, as bridges are also susceptible to being damaged during earthquake events. On the Oregon coast, many towns are connected both inland and to each other by bridges. Waldport is such an example, having all 3 of its major roads on bridges less than a mile out of town. According to Oregon State University, most of the coastal bridges in the state have a very high chance of collapsing and/or sustaining major damage, or being inundated with water due to a subsequent tsunami. The risk of infrastructure collapse (and potential loss of life due to collapse) and cost of retrofitting is the first portion of data being assessed. The second section of data being analyzed is the amount of people that would be incapable of moving to safety due to collapse or damage, and the access (or lack thereof) of emergency response services to isolated areas following a seismic hazard event.

One example that demonstrates this is the 2011 Japan earthquake and tsunami event. Many reinforced concrete (RC) buildings failed during the event and were lifted off their foundations. This occurred because entrapped air within these buildings allowed them to be more susceptible to buoyancy forces. In addition, soil liquefaction appears to have destabilized their foundations allowing them to be transported by the waves. Seawalls also failed, possibly due to suction pressure near the crown of the wall. The return flow of the tsunami caused further damage because roads and foundations had been undermined by soil liquefaction. Beyond the damage to buildings, nearly 16,000 people lost their lives. The staggering loss of life and massive amount of damage occurred in a country that was thought to have “invulnerable” buildings and other structures built specifically for tsunamis. The 2011 Japan event illustrates the scale of destruction that can occur from an earthquake and tsunami of this magnitude. Even so, there are ways to minimize damage and prevent loss of life. For example, in Japan, breakaway walls, windows, and doors allowed water to flow into buildings, keeping them from being lifted from their foundation. Shadow zones behind RC buildings, protected weaker structures from being destroyed. New strategies are currently being developed to help minimize death and destruction from tsunamis. Studies of tree distribution are being used to lessen the forces associated with tsunami waves. Stricter building codes, improved infrastructure design and planning, and other mitigation efforts can save lives and promote resiliency for communities that may face an earthquake and tsunami of the size and scope of the Japan 2011 event.

The lack of roads along the lake's shores led woodsmen to transport their ties by boat to south shore to sell them to merchants for $5 to $10 each. The boys on the beach are Carlos and Alex Bratz whose grandparents pioneered the area.

The first teacher, Teodoro Mättig, expanded the school to include the sixth grade. Professor Mattig, likewise, was a strong proponent for the Caburgua school, improved roads, and innocative forestry and farming.

Paths were more direct and less dusty in summer and muddy in winter. Only residents knew these routes.
