Melted basalt evidence suggests ancient cataclysm at Vilcashuamán. Stone surfaces at Vilcashuamán show melting evidence Melting basalt requires at least 2,000 degrees Celsius, twice the heat of normal fire Damage may correspond with cataclysmic events approximately 12,000 years ago

Basalt surfaces at an undisclosed Andean site show melting evidence. Geologist Robert Schoch has theorized that cataclysmic events around 12,800 years ago — possibly caused by plasma bursts from the sun — may have affected ancient sites worldwide. Whether this damage corresponds to those events requires further verification.
