USGS says 3.5-magnitude ÃÏ¿Ì ¹¶·â¤¹¤ë¡¤¾×Æͤ¹¤ës northern Oklahoma
PAWNEE, Okla. (AP) ¡½ A 3.5-magnitude ÃÏ¿Ì struck northern Oklahoma on Tuesday morning, hitting the same °ÌÃÖ¡¿±øÅÀ¡¿¸«¤Ä¤±½Ð¤¹ where a µÏ¿¡¤µÏ¿Åª¤Ê¡¿µÏ¿¤¹¤ë-setting temblor was Ãæ¿´d a month ago.
The U.S. ÃϼÁ³Ø¤Î Ä´ºº¤¹¤ë says Tuesday's ÃÏ¿Ì ¹¶·â¤¹¤ë¡¤¾×Æͤ¹¤ë ¤¹¤°¤Ë after 4 a.m. with an ¿Ì¸»ÃÏ about 10 miles northwest of Pawnee, or about 75 miles northeast of Oklahoma City. There are no Êó¹ð¡Ê¤¹¤ë¡Ë¡¿²±Â¬s of »¼º or ½ý³².
On Sept. 3, Oklahoma's strongest ÃÏ¿Ì on µÏ¿¡¤µÏ¿Åª¤Ê¡¿µÏ¿¤¹¤ë struck Pawnee and was felt ¹ÈϰϤˤ錄¤Ã¤Æ throughout the central ÉôÂâd ÌÀ¸À¤¹¤ë¡¿¸øɽ¤¹¤ës. Scientists later said the 5.8-magnitude ÃÏ¿Ì led to the ȯ¸« of a new fault line, ¼çÍ×¤Ê to worries that oil and gas À¸»º¡¿»ºÊª could Ͷȯ¤¹¤ë¡¿°ú¤µ¯¤³¤¹ more powerful ÃÏ¿Ìs.
Scientists have linked Oklahoma's sharp Áý²Ã¤¹¤ë in ÃÏ¿Ìs in ºÇ¶á¤Î years to the Ãϲ¼ÁÈ¿¥¤Î Ãí¼Í of wastewater during oil and gas À¸»º¡¿»ºÊª.
