Firefighters were busy this morning extinguishing two house fires on different parts of the island.

In Ewa Beach, a 2-alarm fire broke out at a two-story townhouse at 91-593 Kuiloloa Place at about 5:10 a.m.

Arriving firefighters saw heavy smoke coming from a utility room outside of the unit, said Fire Department spokesman Capt. David Jenkins in an email.

Firefighters had the fire under control by 5:25 a.m. and extinguished by 6 a.m.

No one was home at the time of the fire.

Jenkins said other residents at the townhouse complex evacuated after they smelled smoke and heard other neighbors alerting them of the fire. No injuries were reported.

At about 2:44 a.m., firefighters responded to a fire at a vacant, single-family home at 45-643 Kaneke St. in Kaneohe.

Eighteen firefighters responded and saw smoke and flames flaring from the front of the home, Jenkins said.

Firefighters used foam to prevent the fire from spreading. The blaze was brought under control shortly before 3 a.m. and extinguished at 3:08 a.m.

Investigators are still determining the cause and damage estimates for both fires.
