EARTHQUAKES IN THE MARIANAS ISLANDS.
----+--------------------+-----+------------------------------------------ No. | Date. |Intensity. | | | Epicenter and effects. ----+--------------------+-----+------------------------------------------ | _Y. M. d. h. m._ | | 1 |1825 IV -- -- -- |VIII |Destructive earthquake in the Marinas or | | |Ladrones group of islands. Ruined many | | |buildings at Agaña, Guam Island. | | | 2 |1834 V -- -- -- |VIII |Destructive earthquake on Guam Island. | | |Considerable havoc and great panic at | | |Agaña and in the other towns of the | | |island. | | | 3 |1849 I 25 14 56 | IX |Destructive earthquake. Laid in ruins all | | |the masonry buildings on the islands--the | | |church, _convento_, and college at Agaña, | | |the churches at Umata, Pago, and Agat, | | |together with a great number of houses. | | |Immense fissures opened in many places, | | |and an extraordinary commotion of short | | |duration was observed in the sea. There | | |followed countless aftershocks, some of | | |them very intense; from January 25 to | | |March 11 no fewer than 150 were actually | | |counted. | | | 4 |1862 VII 1 7 48 | VII |Violent earthquake. Did great damage to | | |the tile roofs at Agaña and in other towns | | |on the Island of Guam. | | | 5 |1863 XII 7 3 -- | VI |Guam. Violent earthquake causing great | | |alarm but little harm. | | | 6 |1866 VI 24 13 -- | VI |Guam. Very strong earthquake. | | | 7 |1870 V 13 15 27 | VI |Guam. Two very strong shocks at an | | |interval of 10 seconds. The fact that they | | |did no damage has been attributed to the | | |absence of horizontal movements. | | | 8 |1892 V 16 21 10 |VIII |Destructive earthquake which severely | | |damaged the masonry buildings in Agaña and | | |other towns, produced many fissures and | | |displacements on the coasts and in other | | |places. The sea retired suddenly, but no | | |devastating alternations of floods and | | |ebbs followed. The few aftershocks which | | |occurred during the two following days | | |were feeble. | | | 9 |1902 IX 22 11 15 | IX |Destructive earthquake which wrecked or | | |damaged very seriously all the buildings | | |at Agaña, Guam. Great fissures opened in | | |the ground and displacements occurred | | |which resulted in the destruction of | | |several bridges. Similar effects are | | |reported from Saipan Island. Personal | | |accidents were limited to a few injured. | | |Aftershocks were very numerous during the | | |first days after the earthquake. | | | 10 |1902 XII 24 7 15 | VI |Very strong earthquake lasting over a | | |minute. At this time the aftershocks of | | |the earthquake of September 22 were still | | |continuing. | | | 11 |1903 II 10 12 39 | VII |Guam. Violent earthquake which damaged to | | |some extent the government house at Agaña. | | |Two distinct series of shocks were | | |observed, having a total duration of more | | |than a minute. | | | ----+--------------------+-----+------------------------------------------ No. | Date. |Intensity. | | | Epicenter and effects. ----+--------------------+-----+------------------------------------------ | _Y. M. d. h. m._ | | 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 Agaña 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 | | |information from the other islands. | | |
