2 Days and 25 Temblors 200 Miles WSW of Guam, All Leave the Island Unmoved

394

Guam – As of  Monday morning, in the wake of  Saturday morning’s 6.9 earthquake, 25 subsequent quakes, or after shocks, each measuring 4.6 or greater, have disturbed the ocean floor more than 200 miles west south-west of Guam.  But not one of them has disturbed island residents.

No tsunami warnings or watches were issued, no injuries, no damage.  In fact few, if any, residents felt anything at all from the 25 temblors which struck too far away to impact the island.

It started  7:20am Saturday morning  when, what was first measured as a 7.2 earthquake struck about 230 miles WSW  of the island. That shaker was later downgraded to a 6.9 temblor.

Of the 25 quakes over the past 2 days, 3 of them measured in the 6.0 range; 14 registered between 5.0 and 6.0 in magnitude. and 8 between 4.6 and 4.9.

All of them have shaken the same region of the Philippine Sea floor, between 210 and 250 miles west, southwest of Guam.

The National Weather Service in Tiyan keeps track of earthquake activity in the region.  Senior Forecaster Mike Ziobro told PNC News Sunday he didn’t feel any of them, and doesn’t know anyone who did.  He says their office fielded a number of calls Saturday morning from international media asking whether Guam felt the impact, and his answer was “Nope. Didn’t feel a thing.”

Sunday, Guam Homeland Security and the Office of Civil Defense issued a release recommending that all residents review their Family Emergency Plan, stock their Emergency Supply Kit and become familiar with earthquake safety procedures and the tsunami evacuation route and assembly area nearest you.
