2018 Gulf of Alaska earthquake

On January 23, 2018, at 00:31 AKST, an earthquake occurred in the Gulf of Alaska near Kodiak Island. The earthquake, measured at 7.9 on the Mw scale, was approximately 280 kilometers (170 mi) southeast of Kodiak and happened at a depth of 25 kilometers (16 mi). It was initially measured as a M 8.2 event, but later downgraded by the United States Geological Survey. The earthquake was felt throughout most of southern Alaska, including the major cities of Anchorage and Fairbanks, and parts of neighboring British Columbia.

William Jessop was born

William Jessop was an English civil engineer, best known for his work on canals, harbours and early railways in the late 18th and early 19th centuries. The first major work that Jessop is known to have carried out was the Grand Canal of Ireland. This had begun as a Government project in 1753, and it had taken seventeen years to build fourteen miles (21 km) of canal from the Dublin end.

1556 Shaanxi earthquake

The 1556 Shaanxi earthquake occurred in the early morning of 23 January 1556 in Huaxian, Shaanxi during the Ming dynasty. Most of the residents there lived in yaodongs-artificial caves in loess cliffs-which collapsed and buried alive those sleeping inside. Modern estimates put the direct deaths from the earthquake at over 100,000, while over 700,000 migrated away or died from famine and plagues, which summed up to a total loss of 830,000 people in Imperial records. It was the deadliest recorded earthquake in history, and in turn one of the deadliest natural disasters in Chinese history.
