Scientists surprised by the strength of earthquake-triggered tsunami in Sulawesi island

An earthquake struck Sulawesi, causing a tsunami that hit Palu City. The quake was a strike-slip type, breaking ground horizontally. It may have triggered an underwater landslide, destabilizing sediment. Palu's bay shape possibly amplified the tsunami's effect.

What was the height of the tsunami waves that hit Palu City?

• 3 meters

• 6 meters

• 12 meters

• 9 meters

How does a strike-slip earthquake differ from other types?

• It causes vertical ground movement.

• It leads to diagonal ground movement.

• It causes horizontal ground movement.

• It results in circular ground movement.

What natural event do scientists think the earthquake might have triggered?

• A volcanic eruption

• A forest fire

• A hurricane

• An underwater landslide

What geographical feature of Palu's bay might have increased the tsunami's effect?

• Its elongated shape

• Its shallow depth

• Its circular shape

• Its rocky bottom

Which of the following is NOT a suspected cause of the tsunami's intensity?

• The earthquake's magnitude

• The presence of a nearby volcano

• The shape of Palu's bay

• The underwater landslide
