"I felt it" reports:
Andersen AFB / MMI VI (Strong shaking): First earthquake and I was surprised how loud it was
Bell Tower Plaza, Agana, Guam / MMI VI (Strong shaking): The shake started and after 8 seconds I got up from my desk and got under my door jamb. I started counting off ("1 thousand, 2 thousand...") and so forth till I reached 40 seconds and the shaking continued. All in all this quake lasted more than a minute. All we suffered was acoustic ceiling tile came down with a 14 inch piece of frame which was used to hold up the acoustic ceiling tile.
Kagman,Saipan, CNMI / MMI III (Weak shaking): Rolling back and forth twice followed by short vibration in seat. I was sitting on a medical stool with wheels.
Andersen AFB, Guam (57.6 km ESE from epicenter) [Map] / MMI VI (Strong shaking): I was just walking into work when the shaking started. I'm not new to earthquakes so I wasn't alarmed.
Guahan/Nanbo Bldg. Hagatna, Guam (49.8 km SE from epicenter) [Map] / MMI VI (Strong shaking): Glass Doors were shaking and lasted almost 30 seconds at Suite 202 Guahan Building Route 4, Hagatna, Gu 96919

Naval Base Guam (47.6 km SSE from epicenter) [Map] / MMI VI (Strong shaking): It was quite sudden, but lasted more than 30 seconds. It started as a rumble, then got stronger after the first few seconds, shaking the entire base house, all walls and floors reverberating and feeling like I was "lifted" up a little from ground zero. It was definitely strong, as all the neighbors rushed out of their doors to swipe sweat from their heads, "whew, that was intense!"
Alupang Beach Tower, Tamuning Guam (50.3 km SE from epicenter) [Map] / MMI VI (Strong shaking): There was a loud noise before the earthquake, the kind of noise that makes you feel dizzy and then the noise was followed by a long and strong earthquake.
