Hierro Today, Gone Tomorrow

Lunghu has been keeping an occasional eye (metaphorically speaking) on seismic developments in the Canary Islands.   El Hierro Island is furthest south and west in the island group, which means that there’s nothing but ocean between them and us [North Americans].

What:

Instituto Geográfico Nacional (IGN) reported that during 2-8 November the submarine eruption continued south of El Hierro Island. Tremor amplitude reached higher values than during previous weeks….  During 2-8 November, 364 seismic events were recorded, most of them located offshore to the N of the island, at depths of 16-23 km.

The massive Hierro shield volcano is truncated by a large NW-facing escarpment formed as a result of gravitational collapse of El Golfo volcano about 130,000 years ago. The steep-sided 1500-m-high scarp towers above a low lava platform bordering 12-km-wide El Golfo Bay.

So what:

Lunghu’s not gonna claim that this is a widely-held belief among paleo-geologists, but to his eye the landscape of New York’s Long Island and the New Jersey coastal plain suggests the possibility that the low, rolling sandy hills to be found there were long ago formed by a massive tsunami originating somewhere “way out there” to the southeast.  Somewhere like the Canary Islands, perhaps.

Just sayin’ …

    And what sort of elevation would lunghu recommend one be at to avoid being swept out over those lovely, rolling hills?
