“…Benthic animals on tidal flats are frequently damaged by natural and artificial catastrophic events, such as heavy sedimentation [1], storms [2], tsunamis [3–5], hypoxia [6–8], oil spills [9], dredging [10], introduced species [11–14], and reclamation [15], and full recovery from these events can take a minimum of 15–25 years [16]. Therefore, in order to examine the ecological impacts and recovery trajectory from these catastrophic events, long-term datasets from at least 15 years before and after the events are necessary.…”

“…We monitored annual changes in species densities of mollusks for ten years before and five years after the 2011 earthquake, and subsequent tsunami, at the Tona Coast (Fig 1B), Higashi-Matsushima City, Miyagi Prefecture [11, 27]. Around the Tona Coast, a huge tsunami arrived from the landside through the Nobiru Coast (arrow in Fig 1B).…”

“…In the present study, we aimed to document the structural changes in the molluscan community over a 15-year period before and after the 2011 Great East Japan Earthquake and subsequent tsunami. With established baseline data before from the region [11, 27], we discuss the recovery trajectory of the molluscan community after this catastrophic event.…”

We examined structural changes in the molluscan community for ten years (2001–2010) before and five years (2011–2015) after the 2011 Great East Japan Earthquake and subsequent tsunami around Matsushima Bay, Miyagi Prefecture, northeastern Japan. Before the earthquake and tsunami, Ruditapes philippinarum, Macoma incongrua, Pillucina pisidium, and Batillaria cumingii were dominant, and an alien predator Laguncula pulchella appeared in 2002 and increased in number. After the tsunami, R. philippinarum and M. incongrua populations quickly recovered in 2012, but P. pisidium and B. cumingii populations did not recover until 2015. By contrast, Musculista senhousia, Mya arenaria, Retusa sp., and Solen strictus were found in low densities before the tsunami, but they rapidly increased in abundance/number over five years after the tsunami. These results suggest that the molluscan community on the Tona Coast was drastically changed by the earthquake and tsunami, and some species mainly inhabiting the intertidal—subtidal zone may have increased in number because of land subsidence. We also emphasize that the seawall delayed recovery of the intertidal community after the earthquake and tsunami.

“…This is an alien species in northern Japan and was introduced with the imported Manila clam Ruditapes philippinarum from China and Korea for seeding and shellfish gathering (Okoshi 2004). As L. pulchella prefers to prey on the Manila clam Sato et al 2012), there was a concern that it would cause great damage to clam production in northern Japan (Okoshi 2007), including in Miyagi and Fukushima prefectures (Tomiyama et al 2011;Okoshi and Sato-Okoshi 2011;Abe et al 2017).…”

The “tsunami break:” impact of the Great East Japan Earthquake and the accompanying tsunamis on the shell growth of the invasive clam-eating snail Laguncula pulchella

The Great East Japan Earthquake and accompanying tsunamis occurred on 11 March 2011, causing huge damage to marine organisms. The invasive naticid gastropod Laguncula pulchella (Euspira fortunei), which was introduced with the imported clam Ruditapes philippinarum from China and Korea, survived the earthquake. The "growth break line" observed on the shell surface in over 90% of the individuals collected in Matsushima Bay and Matsukawa-ura Lagoon after the tsunamis was examined by scanning electron microscopy. Each shell presented three layers before and three after the growth break. However, the fracture surface consisted of five layers-two prismatic and three crossed lamellar-around the growth break line. This suggests that shell formation temporarily ceased following the tsunamis and that the five-layered shell may have developed in response to the stress caused by the tsunamis. The newly formed middle layer became thinner after the "tsunami break," which may be the result of a rapid change in the mineralization process, including rapid shell growth and/or repair. These results suggest that the damage to and forcible removal of habitats by the tsunamis was stressful for L. pulchella. A decrease in or the cessation of shell formation after a tsunami may be a common phenomenon in mollusks that inhabit tidal flats.
