Understanding the EIA Test. Several types of EIA tests exist. Validated and FDA-approved EIAs include âELISAâ (enzyme-linked immunosorbent assay) and âELFAâ (enzyme-linked fluorescent immunoassay). Lyme disease testing measures a person's antibody (or immune response) to the bacteria that cause Lyme disease.
This is precisely the case for a deadly stratovolcano Mt Rainier-which puts upwards of 100,000 lives at risk where there may only be 15-30 minutes to run for high ground from a sudden Lahar (volcanic mudflow). Yet this pales in comparison to a sudden cataclysmic eruption of a supervolcano (Like Yellowstone Park).his is precisely the case for a deadly stratovolcano Mt Rainier-which puts upwards of 100,000 lives at risk where there may only be 15-30 minutes to run for high ground from a sudden Lahar (volcanic mudflow).

A stratovolcano, also known as a composite volcano, is a conical volcano built up by many layers of hardened lava, tephra, pumice, and volcanic ash. Unlike shield volcanoes, stratovolcanoes are characterized by a steep profile and periodic explosive eruptions and effusive eruptions, although some have collapsed craters called calderas. The lava flowing from stratovolcanoes typically cools and hardens before spreading far due to high viscosity. The magma forming this lava is often felsic, having
