Also NYC was shaken

“New York City shakes as 4.8 magnitude earthquake hits US north-east” https://www.theguardian.com/us-news/2024/apr/05/earthquake-new-york-new-jersey


4月5日に紐育でマグニチュード4.8の地震ということなのだが。震源地はニュージャージー州レバノン*1、米国東北部一帯で揺れが感じられた。
さて、2011年9月にも米国東海岸は(もっと広い範囲で)地震で揺れたのだった;


The shaking stirred memories of the 23 August 2011, earthquake that jolted tens of millions of people from Georgia to Canada. Registering magnitude 5.8, it was the strongest quake to hit the east coast since the second world war. The epicenter was in Virginia.

That earthquake left cracks in the Washington Monument, spurred the evacuation of the White House and Capitol and rattled New Yorkers three weeks before the 10th anniversary of the September 11 terror attacks.
