Lee and AZGS colleagues—
ReplyDeleteThanks for your rapid and frequently updated posts on the US89 slide. ASU SESE got a lot of inquiries from the Phoenix media yesterday, and this quick information was very helpful! Your blog got a mention on the channel 12 news yesterday. Thanks also to my homie Ron Schott for the annotated image.
Is this an indication of posible earthquake in the region? Thanks.

Maria, there were no earthquakes detected anywhere in the area around that time.
ReplyDeleteThis is cool!
