placed the moment magnitude at 8.2, along with a depth of 46 km (29 mi)
BMKG’s own publications for this event identify it as magnitude 7.7, not 8.2. BMKG’s official tsunami-warning page also lists a much deeper hypocenter of 105 km.
Full reasoning
BMKG’s official tsunami-warning page for this earthquake identifies it as M 7.7 with a depth of 105 km, not magnitude 8.2. BMKG’s own press release the same day also repeatedly refers to the event as “Gempa M7,7 Filipina” and describes it as 47 km deep. In other words, the article is attributing an 8.2 magnitude to BMKG that BMKG’s own published materials do not give for this event.
Because the sentence explicitly says BMKG placed the quake at 8.2, it is factually incorrect as written. The 8.2 figure appears in some other agencies’ early products, but BMKG’s own published figures for this event were 7.7, not 8.2.

with the highest recorded measurement at Talengan-Sulut at 1.5 m (4 ft 11 in)
BMKG reported the Talengen/Talengan tsunami height as 0.75 m, not 1.5 m. PTWC’s bulletin likewise listed Talengen at 0.83 m.
Full reasoning
The article’s stated peak tsunami height at Talengan/Talengen is doubled.
BMKG’s official press release says the tsunami at Talengan reached 0.75 m at 08:20 WIB. The Pacific Tsunami Warning Center’s bulletin for the same event likewise lists TALENGEN at 0.83 m / 2.7 ft. Both authoritative sources contradict the article’s claim that the highest measurement there was 1.5 m (4 ft 11 in).
So while tsunami waves were indeed observed at Talengen/Talengan, the specific height given here is not supported by the official measurements and is substantially too high.
