12 |1909 XII 10 9 0 |VIII |Guam. Destructive earthquake. Two shocks
| | |lasting 20 seconds, of which the second
| | |was the more severe. Direction of the
| | |shocks SE-NW. In Agana practically all the
| | |east and west walls of native mortar
| | |houses were badly cracked. In nearly every
| | |house articles on shelves of these walls
| | |were thrown down, while those on the north
| | |and south sides remained in place. The
| | |women's hospital, built of local mortar,
| | |was so badly injured as to require tearing
| | |down; its tiled roof slid off to westward
| | |and the worst cracks were in the east
| | |wall. Many ceiling boards in different
| | |houses were shaken down. Several fissures
| | |opened in the ground, from one of which,
| | |near the river, came a large flow of
| | |water. The river bed sank in several
| | |places. The passing wave could be seen
| | |distinctly as it crossed the plaza, and
| | |the station ship in the harbor reported
| | |having felt the shock. No damage of
| | |importance was done in the other towns on
| | |the island. The buildings of the cable
| | |station at Sumay, constructed of
| | |reinforced concrete, were not injured, but
| | |a few objects were thrown down and the
| | |steel water towers could be seen swaying.
| | |No shocks were noticed before or after the
| | |earthquake, nor was anything extraordinary
| | |observed in the sea. The disturbance was
| | |not felt at Yap, Western Carolines. No
