Contradictions
Conflicting information between sources:
- ABC reported the earthquake’s magnitude was 7.4 from the start, while the Guardian initially stated USGS recorded it as 7.8 before revision
- ABC mentioned confirmed fatalities (one death in Manado) and building damage, but NEWSCOMAU and GUARDIAN did not report confirmed deaths or specific damage
- ABC stated PHIVOLCS explicitly denied a destructive tsunami threat to the Philippines, while NEWSCOMAU and GUARDIAN only mentioned potential waves without PHIVOLCS’ denial
- ABC reported tsunami waves of 0.3m in West Halmahera and 0.2m in Bitung, while NEWSCOMAU and GUARDIAN did not specify these exact measurements
- The Guardian described prolonged shaking in Manado with no significant damage, while ABC included a resident’s account of panic and power cuts
