Since relatively little archaeology has been done in Bolivia and probably mostly at known and accessible sites, it might be worthwhile in future for archaeologists/geologists to visit some of these earthquake-destroyed sites to try and determine the dates of their destruction, including the ringed hilltops (link at bottom of page).
Above, region near Bombo, east of Lake Poopo. The diagonal line is the remains of either railway
or possible irrigation canal running for a distance of about 8 miles and whose route has been completely destroyed by earthquakes.

Above, earthquakes have clearly destroyed the eastern half of this hill
in the mountains south west of Oruro.
Above, this photo shows flattening by earthquakes near the above ringed hill south west of Oruro.
Above, fields now on mountain sides suggest earthquake uplifiting in this area south of Turco.
Above, earthquake activity appears along this ridge with circular feature in this zone south of Turco.

Above, enlargement from previous photo, the arrows point to remains
of agricultural system with column windbreaks and circular piles of stones.
Above, earthquake activity appears in this zone south of La Paz with "geoglyph" agriculture, appears to show as "smoothed" grey areas.
Above, the terraces seem to be from a later period to the original "geoglyph" agriculture.
Above, the original "geoglyph" agriculture system seems to have been struck by earthquakes with fissures opening in the land afterwards.

Above, these appear to be fissures as a result of earthquakes amongst the original
"geoglyph" agriculture system in this ridge of mountains immediately north of Tiwanaku.
Above, the southern flank of this ridge of hills to the north of Tiwanaku
appears to be fissures as a result of earthquakes.
Above, on this ridge, to the north of Tiwanaku, the north flank shows "geoglyph" agriculture system
while the south flank shows what appears to be fissures as a result of earthquakes with remains of the agricultural system in between the fissures.

"geoglyph" agriculture system in this ridge of mountains immediately north of Tiwanaku. It may be worth
to investigate this zone further to see if dates can be obtained for destruction by earthquakes and to confirm whether
the agriculture was developed before or after the fissures opened.
