Earthquake swarm rattles the Japanese Ryukyu islands
For almost two weeks, an earthquake swarm has been shaking the remote Japanese islands of Takarajima, Kodakarajima, and Akusekijima. Reports from the region indicate that this swarm has been particularly uncomfortable for the few residents of the nearby islands, who have been subjected to almost constant tremors for more than ten days.
These islands are part of a group of twelve tiny above-water peaks know as the Tokara Islands, which form part of the much larger volcanic arc that has been produced by the westward subduction of the Philippine Sea plate beneath the Ryukyu Arc.
There is a nesting-doll-esque naming convention here: the Tokara Islands are a part of the Nansei Islands, which are part of the Satsunan Islands, which are part of the Rkyukyu Archipelago.
There have been more than five hundred recorded earthquakes over the last two weeks, over a dozen above magnitude 5, and the largest so far (M5.6) was just a few hours ago. Although these earthquakes are not large enough to cause significant damage, rumors have been spreading about the possibility of larger events, including about a fictional “Law of Tokara,” which states that a swarm of earthquakes in the Tokara Islands foreshadows a larger earthquake elsewhere. To be clear: there is no such law; it barely even rises to the level of pseudoscience.
But something certainly is going on below these islands!
The energy of the M6.6 earthquake could result in a worst-case scenario with another earthquake of the same magnitude in the south-central region of Chile, although events in the Sandwich Islands or the Indian Ocean cannot be ruled out.
