Geologists Report Quake Cluster in Idaho - Yahoo! News
BOISE, Idaho - A cluster of earthquakes south of Cascade has been shaking items off shelves and jolting residents out of their sleep this week.

"The dog starts barking every single time," said Armen Mannschreck, a high school English teacher who lives near Clear Creek. A temblor Tuesday night — the strongest so far — sent a bowl crashing to the floor from a dresser in Mannschreck's house.

It also set the cabinet doors swinging at the home of Linda Jarvis, another Clear Creek resident who is regularly awakened by middle-of-the-night quakes these days. Jarvis said she's often felt tremors in the 19 years she's lived at her home — but only in the last week have they been strong enough to get her up in the night.

"The cat wakes up; my cabinet doors in the kitchen go open and closed and I have mortar coming out of the brick on my fireplace outside," Jarvis said.

Residents of the Clear Creek area, about 10 miles south and southeast of Cascade, have been calling seismologists to report feeling several earthquakes a day, said Idaho Geological Survey geologist Bill Phillips. IGS instruments have been recording from 50 to 100 earthquakes per day around Clear Creek in the last week
