Facies association model of submarine explosive eruption (from Allen and Mcphie 2009). Suspension deposit is composed of giant pumice and small ash (bimodal) in top deposits which resulted from pumice gradually wetting and weighting and subsidence occurring near volcanic vent after eruption when eruption ejected giant pumice; suspension deposit only contains small ash and is lack of pumice whose thickness obviously decreased if the deposit area is far away from volcanic vent or pumice ejected from eruption is limited
