context_page_description: 3 Mile is a suburb of Lae in the Morobe Province, Papua New Guinea.
context_section_description: 3 Mile is located 3 miles (4.8 km) from the center of Lae on the Highlands Highway between the foothills of the Atzera Range and the Markham River. The Atzera Range starts at Bugandi and runs adjacent to the Markham River has an elevation of 280 meters above sea level.
  Anticlines in the vicinity of Lae, such as the Atzera Range and hills near Situm, appear to indicate that the Ramu-Markham Fault 
  (which follows the northern edge of the Markham Valley) changes dip close to the surface from a steep ramp to a shallow fault, breaching the surface south of Lae.
  Before the construction of the Highlands Highway, a road in the Atzera foothills connected Nadzab with Lae and a rough trail on the other side of the Atzeras paralleled this road from Lae to Yalu. Jensen's plantation was located in the Markham Valley and the location of battles between Japanese and Australian soldiers. On 10 September the 25th Australian Infantry Brigade moved East from Nadzab towards Lae along the Atzera foothills while the 9th Division approached Lae from the East and on 16 September both units converged on Lae
  The Lae Seismic Zone has been identified between the Atzera Range and Situm which has the potential to generate shallow Mw~7.0 earthquakes and landslides around the Atzera Range. The possibility of major landsides in this area has increased as a result of human modification to the natural vegetation cover through clearing and gardening.
  The 1983 floods remain the worst natural disaster since the establishment of the town in the late 1920s. Hundreds of people at the Five 
  Mile settlement along the Highland Highway were also affected by mud-slides from the Atzera mountain ranges.
