USGS briefing and report highlight expanded rollout of earthquake early warning system

Cracked road from earthquake

The United States Geological Survey (USGS) held a briefing on October 2 to discuss the ongoing rollout of the ShakeAlert Earthquake Early Warning System. The briefing was held in conjunction with the release of a new USGS report on the status of and implementation plan for ShakeAlert. Effective implementation of the ShakeAlert System can reduce the impact of earthquakes, save lives, and protect property in earthquake-prone areas.

Geoscience for Community Priorities

Wednesday, November 14, 2018

Background:
The geosciences provide valuable knowledge and tools that can be applied to a wide range of community issues, including air and water quality; geologic hazards; the provision of energy, water, and mineral resources; climate and weather impacts; and the construction and maintenance of infrastructure. Geoscientists are commonly keen to see this science put into action, but there are many factors that affect how geoscience is perceived and used in community decision-making. Communities vary tremendously in size, location, culture, history, resources, governance, priorities, and needs. Effective engagement strategies take account of this diversity and employ a range of approaches to support communities and individual decision-makers with science that they can trust, understand, and use.

In this webinar, experts in geoscience communication, education, and engagement discuss a variety of different techniques, media, and principles for more effective communication and collaboration between community leaders, decision makers, and geoscientists. Particular attention is paid to three types of engagement: facilitating community-led solutions by connecting community leaders with geoscientists; incorporating community issues into college-level geoscience curricula; and using online platforms to provide geoscience information, resources, access to expertise, and opportunities for communities facing similar issues to share their experiences.

Communities and Scientists Working Together

Interactive map of California earthquake hazard zones

The California Geological Survey’s Earthquake Hazards Zone Application (EQ Zapp) is an interactive map that details the risk of earthquakes and related hazards for different areas of the state.

The map is searchable by address, and it maps three main hazard zones:

  • Fault zones
  • Landslide zones
  • Liquefaction zones

The map also displays areas that have not yet been evaluated for liquefaction or landslides.

An Introduction to Landslides and Mass Wasting

This course is designed to be an introduction to the subject of landslides or mass wasting. Landslides or mass wasting occur in both solid bedrock and in poorly-consolidated sediments. Concerning the latter, loose sands, clays and soft shales can prove to be quite problematic. These type of strata are highlighted in our discussions. We will start with a basic review of soil mechanics and strength of materials, as a precursor to our coverage of the topic of landslides.
