2019 Supplemental Appropriations Activities
The Additional Supplemental Appropriations for Disaster Relief Act of 2019 (H.R. 2157) was signed by the President on June 6, 2019. The USGS received $98.5 million to support recovery and rebuilding activities in the wake of the 2018 Kīlauea volcano eruption, Hurricanes Florence and Michael, the Anchorage earthquake, and California wildfires.
USGS activities funded under the FY2019 Additional Supplemental Appropriations for Disaster Relief Requirements Act include:

Forecasting the frequency and magnitude of postfire debris flows across southern California Forecasting the frequency and magnitude of postfire debris flows across southern California
Southern California has a long history of damaging debris flows after wildfire. Despite recurrent loss, forecasts of the frequency and magnitude of postfire debris flows are not available for the region like they are for earthquakes. Instead, debris flow hazards are typically assessed in a reactive manner after wildfires. Such assessments are crucial for evaluating debris flow risk by...

Time since burning and rainfall characteristics impact post-fire debris flow initiation and magnitude Time since burning and rainfall characteristics impact post-fire debris flow initiation and magnitude
The extreme heat from wildfire alters soil properties and incinerates vegetation, leading to changes in infiltration capacity, ground cover, soil erodibility, and rainfall interception. These changes promote elevated rates of runoff and sediment transport that increase the likelihood of runoff-generated debris flows. Debris flows are most common in the year immediately following wildfire...

The birth of a Hawaiian fissure eruption The birth of a Hawaiian fissure eruption
Most basaltic explosive eruptions intensify abruptly, allowing little time to document processes at the start of eruption. One opportunity came with the initiation of activity from fissure 8 (F8) during the 2018 eruption on the lower East Rift Zone of Kīlauea, Hawaii. F8 erupted in four episodes. We recorded 28 min of high‐definition video during a 51‐min period, capturing the onset of...

The cascading origin of the 2018 Kīlauea eruption and implications for future forecasting The cascading origin of the 2018 Kīlauea eruption and implications for future forecasting
The 2018 summit and flank eruption of Kīlauea Volcano was one of the largest volcanic events in Hawaiʻi in 200 years. Data suggest that a backup in the magma plumbing system at the long-lived Puʻu ʻŌʻō eruption site caused widespread pressurization in the volcano, driving magma into the lower flank. The eruption evolved, and its impact expanded, as a sequence of cascading events...

Increasing threat of coastal groundwater hazards from sea-level rise in California Increasing threat of coastal groundwater hazards from sea-level rise in California
Projected sea-level rise will raise coastal water tables, resulting in groundwater hazards that threaten shallow infrastructure and coastal ecosystem resilience. Here we model a range of sea-level rise scenarios to assess the responses of water tables across the diverse topography and climates of the California coast. With 1 m of sea-level rise, areas flooded from below are predicted to...

Nexus between wildfire, climate change and population growth in California Nexus between wildfire, climate change and population growth in California
Since the year 2000 California has experienced a remarkable upsurge in wildfires. Over five million hectares have burned in the last 20 years, which is double the area burned in the previous two decades. Much of this increase has been driven by large fires of more than 50,000 hectares that cause catastrophic losses of lives and property (Keeley and Syphard 2019). This increased fire...
