Walsingham Cavern | Bermuda | Sediments in submarine cave | 3,100 | Increased storm activity between 3,000 – 1,700 and 600 – 150 years ago; however this record might include extratropical storms | 32.3333°N -104°W | ||
Wassaw Island | Georgia | Overwash | 1,900 | At least eight deposits from strong hurricanes between 1,000 – 2,000 years ago, with a quiet period between 1,100 and 250 years ago | 31.9055°N -80.9969°W | ||
Florida, northwestern | Overwash deposits | 7,000 | Between 3,800 – 1,000 years ago strike probability was about 0.5% per year, followed and preceded by relative inactivity | [6] | 30.3253°N -86.1533°W | ||
Whale Beach | Sand sheets in marshes | AD 1300–present | Two major hurricanes in 700 years, one between 1278–1438 and the other is the 1821 Norfolk and Long Island hurricane | 39.1833°N -74.6714°W | |||
Queensland, northern | Beach ridges | 4,500 | An inactive period between about 3,800 and 2,100 years ago was followed by an active on between 2,100 and 900 years ago | -16.4231°N 145.4189°W | |||
China, southern | Lagoonal sediments | 7,500 | Seven storm periods in the last 7,500 years, including active periods between 5,500 and 3,500 and from 1,700 years ago onwards, with inactive period in between; there are also (in)active periods embedded within these active(inactive) ones and there is more generally a correlation to storm activity elsewhere in southern China and to ENSO variations | 18.4167°N 110°W | |||
Yok Balum Cave | Oxygen isotope ratios in speleothems | AD 1550 – 1983 | After an inactive phase (~1 storm/year) in the middle 16th century, an increase to ~8 storms/year in the 17th century associated with the Little Ice Age. Then a steady decrease until 1870, when occurrence halved and dropped to ~2 storms/year | 16.2086°N -89.0735°W | |||
Yongshu Reef | Coral blocks relocated by storms | 4,000 | Six strikes in 1,000 years, with two during the Little Ice Age and four during the Medieval Climate Anomaly. Also high storm activity around 1200 AD, 400 BC and 1200 BC | 9.6167°N 170°W | |||
Zhejiang-Fujian mud belt | East China Sea | Marine sediment cores | 2,000 | Increased activity between 0–480 CE, 790–1230 CE, and 1940–2018 CE | 28.69°N 122.41°W |
