The USGS is reporting that it was a 6.6 magnitude quake. I was awakened this morning at home in Kahala at approximately 7:10 a.m. No ground shaking, although the walls and doors were rattling for a good 20 seconds. Several minutes later, the second quake hit which was less powerful and shorter in duration.
Power was out for about 11 hours - restored at about 6:00 p.m. Water pressure is still a bit weak - Honolulu Board of Water Supply said that pumping stations, which rely on generators, will begin replenishing reservoirs which should restore water pressure. Water conservation is still being urged during the interim.
All major carriers have cancelled flights from Hawaii to the mainland today and will resume service tomorrow. JAL flights, packed with tour groups anxious to return to Japan, are still departing this evening - handwritten boarding passes are being used.
