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).

The magma forming this lava is often felsic, having high-to-intermediate levels of silica (as in rhyolite, dacite, or andesite), with lesser amounts of less-viscous mafic magma. Extensive felsic lava flows are uncommon, but have travelled as far as 15 km (9.3 mi).Stratovolcanoes are sometimes called composite volcanoes because of their composite layered structure built up from sequential outpourings of eruptive materials.They are among the most common types of volcanoes, in contrast to the less common shield volcanoes.t has been essentially dormant since then. A stratovolcano, also known as a composite volcano, is a conical volcano built up by many layers (strata) of hardened lava, tephra, pumice, and volcanic ash.
