A 6.8-magnitude earthquake struck Kumamoto, Japan on Tuesday, killing at least 13 people and injuring an unknown number. The quake was so powerful that it caused widespread destruction, including collapsing walls at a 17th century castle and a shrine in the city's center. Emergency responders have been mobilized with 4,600 personnel assisting with recovery efforts, but Prime Minister Sanae Takaichi has warned of a "race against time" due to ongoing power and water outages affecting tens of thousands of people. Survivors described the quake as one of the most powerful they've ever experienced, with many still in shock hours after it occurred.

Why this leaning score
The article presents a balanced view, quoting multiple eyewitnesses and officials, and providing details on the damage and response efforts. However, some language used by survivors, such as 'I didn't know what to feel; I couldn't even feel scared in such a situation', may be interpreted as slightly sensational or emotive, leaning towards a sympathetic tone.
Written under an earlier scoring contract, which gave a paragraph
