4830-597: The Portland Hills Fault on the city's west side, and the East Bank Fault on the east side. According to a 2017 survey, several of these faults were characterized as "probably more of a hazard" than the Cascadia subduction zone due to their proximities to population centers, with the potential of producing magnitude 7 earthquakes . Notable earthquakes that have impacted the Portland area in recent history include

In the 1990s, the technology industry began to emerge in Portland, specifically with the establishment of companies such as Intel , which brought more than US$ 10 billion in investments in 1995 alone. In

6785-534: The agricultural Tualatin Valley via the " Great Plank Road " (the route of current-day U.S. Route 26 ), provided the pioneer city with an advantage over other nearby ports, and it grew very quickly.
