The Piparo mud volcano and its tassik on 10th September 2019<\/strong><\/p>\n

The Piparo mud volcano is located within the Naparima Fold Belt of the Central Range of Trinidad. Within the area, the Nariva Formation, a shale dominated unit (up to 3,000\u2019 thick) with minor sands outcrops. The extruded mud contains fragments of fragments of oil impregnated sandstone, chert, fibrous calcite and other lithologies, the origin of some of which cannot be identified. The main vent is located at: E 0681020.534 N 1143191.335 (UTM, Naparima Datum), with an elevation in 2003 of 378.88 feet.<\/h3>\n

Unlike most of the other mud volcanoes in Trinidad, the Piparo mud volcano has extruded a large number of rock clasts in the mud, which cover the tassik of the cone. These clasts are made up of a number of formations which the fluidized mud has passed through on its way to the surface. Fragments of mica rich Nariva sandstone, both oil impregnated and water wet are common, lignite and parallel laminated shales are also common. Coarse Point-a-Pierre sandstones, marls similar to the Lizard Springs, Cuche Shales, chert rich material similar to the Naparima Hill Argilline, occasional greenish sandstone, red mudstones and abundant fibrous calcite occur.<\/h3>\n

Deville et al. (2002) analysed (XRD & MEB) various clasts and the mud matrix . The mud included several types of clays ( kaolinite, illite, smectite & vermiculite) other grains include quartz, feldspar, siderite, rutile, anatase, chlorite and muscovite. The mud was rich in very thin (<3mm), angular and fractured quartz grains ,this and the presence calcite crystals suggested that they were all affected by hydrofracturing.<\/h3>\n

The location of the vents has remained fairly constant over the years, in spite of attempts of misguided visitors and residents to plug the vents with rubbish. The vents are also found along fairly trends the main one being roughly east \u2013 west to the north of the main vent. Other SW \u2013 NE and WNW \u2013 ESE being noted.<\/h2>\n

Of note is that the height of the original mud volcano before the 1997 eruption was around 350 ft, the height in 2003 was 382\u2019 with a range of 360\u2019 \u2013 382\u2019, in 2004 it was 355\u2019 \u2013 364\u2019 and in 2006 it was 349\u2019 \u2013 358\u2019. Thus it appears that the Piparo mud volcano has lost 24\u2019 in height, it is not known if this is due to erosion of the tassik area or deflation of the whole cone. Also note that the 2003 height indicates after the eruption it was 32\u2019 higher mainly due to extrusion of mud. It is clear that there has been changes in elevation over time that cannot be explained by erosion alone. For subsidence along\u00a0 fractures on the tassik. There has been a gradual increase in height up to 2013.<\/h3>\n

THE 1997 ERUPTION<\/h1>\n

First activity of the mud volcano occurred on 25th January 1997. NE \u2013 SW trending cracks appeared across the road. Land around the original crater was uplifted by =\/- 2 feet, the road however subsided by about 2 feet. In the roadway 2 small mud cones about 1 foot high built up, but were not active when visited. Minor amounts of gas was escaping from the cracks in the road. on February 22 February 1997 the main eruption occurred and lasted about 2 minutes. Significant quantities of gas and mud were ejected and covered and area of about 1 hectare.
