Blindsided by Ferocity Unleashed by a Fault

Records kept for the past 300 years indicated that every few decades, part of the Japan trench, an offshore fault to the east of Fukushima, would break, generating an earthquake around magnitude 7.5, perhaps up to magnitude 8.0. While earthquakes that large would be devastating in many parts of the world, the Japanese have diligently prepared for them with stringent building codes and sea walls that are meant to hold back quake-generated tsunamis.

Prehistoric Trash Heaps Created Florida Everglades’ Tree Islands

For many years, scientists thought the fixed tree islands, larger, teardrop-shaped kinds of tree islands often found in the main channel of the Everglades, rose from protrusions from the rocky layer of the mineral carbonate that lies beneath the marsh. Now, researchers suggest these islands might actually have developed from ancient (organic) garbage mounds left behind from human settlements about 5,000 years ago.

California Islands Give Up Evidence of Early Seafaring

The sea-going people may have followed a “kelp highway” stretching from Japan to Kamchatka, along the south coast of Beringia and Alaska, then southward down the Northwest Coast to California. Rising seas have since flooded the shorelines and coastal lowlands where early populations would have spent most of their time.
