Computers Hunting for Avalanches

Hello all! Today we're going to be talking about avalanches. Avalanches are, as you probably already know, dangerous--they are potentially fatal, and can also cause road closures, force evacuations, and cause economic damage. As such, having a good risk assessment for avalanches is important--and as it turns out, difficult. For a good risk assessment, one … Continue reading Computers Hunting for Avalanches

(Lack of) Snow on Hawaii

I know you might be looking at the title of today's post and thinking "snow? Hawaii? How do those two things go together?" and the answer would be mountains. You may also be thinking "why should I care?" and the answer to that would be that snow can be a reservoir of freshwater when melted in the … Continue reading (Lack of) Snow on Hawaii

Sonar “Look” at Hydrothermal Flows

Today we are discussing hydrothermal flows (flows of hot water coming from the center of the earth). In particular, theses flows are diffuse (spread out) and relatively low temperatures (one was measured at 7 to 13 C, or 45 to 55 F) compared to those that can reach 250 C (482 F) or more. These low-temperature flows … Continue reading Sonar “Look” at Hydrothermal Flows

Ceres and Cryovolcanism

Hello readers! Today we are travelling to Ceres, a dwarf planet in the asteroid belt located between Mars and Jupiter. Ceres is not very large--about the size of Texas, at 476 kilometers (276 miles) across. It was first discovered in 1801 and in 2015, was visited by the spacecraft Dawn. Today's featured article, however, was … Continue reading Ceres and Cryovolcanism

Tsunami Warning for Mars

Underground water aquifers under thick permafrost, groundwater breaking through the surface, catastrophically flooding the ground, and forming an ocean in the lowlands. This is the setup for the Hesperian era on Mars, around 3.71 to 3.37 billion years ago. The groundwater would have broken through near the end of the era, around 3.4 billion years ago, … Continue reading Tsunami Warning for Mars
