A volcano plot is constructed by plotting the negative logarithm of the p value on the y axis (usually base 10). This results in data points with low p values (highly significant) appearing toward the top of the plot. The x axis is the logarithm of the fold change between the two conditions. The logarithm of the fold change is used so that ...
Volcano plot showing metabolomic data. The red arrows indicate points-of-interest that display both large magnitude fold-changes (x axis) and high statistical significance (-log10 of p value, y axis). The dashed red line shows where p = 0.05 with points above the line having p < 0.05 and points below the line having p > 0.05.
Cabezon Peak is the solidified core of a volcano that erupted 2.658 ± 0.032 million years ago, based on argon-argon dating. The eruption at this volcano likely began with lava fountains from the vent, which built up a scoria cone. Lava later ponded in the interior of the cone, solidifying into a massive plug.
Volcano plot may refer to: . Sabatier principle - a concept in chemical catalysis that relates the optimal concentrations of catalysts and substrates; Volcano plot (statistics) - a type of graph used to relate fold-change to p-value that is commonly used in genomics and other omic experiments involving thousands of data-points
From July to September 2011, the Canarian island of El Hierro experienced thousands of small tremors, believed to be the result of magma movements beneath the island. This resulted in fears of an imminent volcanic eruption, which began October 10, 2011, approximately 1 km south of the island in a fissure on the ocean floor.
The second-largest volcano in Hawaii had been lying dormant for the last two months after bursting open in January and June this year. “The opening phases of eruptions are dynamic,” said USGS ...
Shock images show roads split apart near Grindavik in Iceland as the country braced for a volcanic eruption following a series of earthquakes and evidence of magma spreading underground.. The ...
The island is an example of hotspot volcanism, [1] with mainly mafic volcanic and igneous rocks, together with smaller deposits of limestone, lignite and other sediments that record its long-running uplift. Distribution of the islands of the archipelago (not including the Savage Islands)
