This timelapse sequence shows the water pond in Halema‘uma‘u Crater, at Kīlauea's summit, between November 1, 2019, and March 26, 2020. Over this time the water level rose approximately 14 meters (46 feet), equivalent to 67 cm (about 2 feet) per week. The timelapse shows one image per day (with a few cloudy images removed), and is looped several times.

The USGS St. Petersburg Coastal and Marine Science Center conducted outreach at the Localtopia Event held in February 2020. Staff demonstrated a simulation of how storms can impact sandy coastlines through processes such as erosion.

Scanning electron microprobe images show the complexity of tiny Icelandic ash grains (150 micron, or 0.006 inch). Image (a) shows a dense and blocky grain, and (b) shows a foamy grain. Photos by J. Schmith.

Answer: a GPS capable of accurately measuring elevations to within 10 cm (~4 in). In the summer of 2019, USGS organized a Light Detection and Ranging (LiDAR) survey of the Kīlauea summit and East Rift Zone, including both the Pu‘u ‘Ō‘ō and 2018 lower Puna lava flows.

The SQUID-5, or a Structure-from-Motion (SfM) Quantitative Underwater Imaging Device with 5 cameras is a towed surface vehicle with an onboard Global Navigation Satellite System (GNSS) and 5 downward-looking cameras with overlapping views of the seafloor.

Question: what's that in the shrubs?

A CTD-rosette is a commonly used instrument that measures conductivity (that can inform scientists about salinity), temperature, and depth (CTD). As the instrument is lowered into the water--sometimes down to great depths--the cylinders around will open at various depths to collect water samples at discrete locations throughout the water column.

Stormy weather moved through the islands over the past day, producing snow at the higher elevations of Mauna Kea and Mauna Loa. This sequence shows the webcam images at the summit of Mauna Loa, and the variable weather throughout the day.

On December 30, 2015, an HVO geologist wore protective gear during collection of a fresh lava sample for chemical analysis from a Pāhoehoe breakout along scattered Pu‘u ‘Ō‘ō lava flows. Inset image caption: Metadata is written on a bag that holds a sample taken from Pāhoehoe that was collected on August 18, 2006.

The water pond at Kīlauea's summit continues to gradually deepen. The pond surface remains variable in color, with a brownish hue in the northern portion, evident through the gaps in steam. USGS photo by D. Swanson.

The sampling mechanism (on blue tarp) is prepared and the Unoccupied Aircraft System (UAS) is inspected just before take off to collect water from the Halema‘uma‘u crater lake. Brightly colored flagging tape tied to a cable attached to the UAS indicated depth as the sampling tool was lowered into the water.

El Servicio Geológico de los EE. UU. ha publicado un informe sobre la duración potencial de las réplicas de la secuencia (serie) del terremoto del Suroeste de Puerto Rico en el 2020 que puede ser usado como guía en las decisiones de política pública, otras acciones y ayudar a las personas a mantenerse seguras y cuidarse a sí mismas y a los demás.

The U.S. Geological Survey has released a report on the potential duration of aftershocks of the 2020 Southwest Puerto Rico earthquake sequence (series) to guide public policy decisions, other actions, and help people stay safe and care for themselves and each other.
