Geomorphic and geologic controls of geohazards induced by Nepal's 2015 Gorkha earthquake.

The Gorkha earthquake (magnitude 7.8) on 25 April 2015 and later aftershocks struck South Asia, killing ~9000 people and damaging a large region. Supported by a large campaign of responsive satellite data acquisitions over the earthquake disaster zone, our team undertook a satellite image survey of the earthquakes' induced geohazards in Nepal and China and an assessment of the geomorphic, tectonic, and lithologic controls on quake-induced landslides. Timely analysis and communication aided response and recovery and informed decision-makers. We mapped 4312 coseismic and postseismic landslides. We also surveyed 491 glacier lakes for earthquake damage but found only nine landslide-impacted lakes and no visible satellite evidence of outbursts. Landslide densities correlate with slope, peak ground acceleration, surface downdrop, and specific metamorphic lithologies and large plutonic intrusions.

Gaze behavior: a new look at an old problem.

This article reviews the research and clinical literature that has investigated the topography and functions of eye-to-face gaze in normal children and adults. These data and data from a recent pilot study are then compared to the criteria typically used in eye-contact training programs with autistic children. This comparison reveals some educationally relevant discrepancies between the normative data and the training criteria. The need to base educational interventions for autistic individuals on normative standards is discussed, and suggestions for future research are provided.

A group therapy program for individuals identified as autistic who are without speech and use facilitated communication.

The first author directed a group-therapy program of 20 sessions for clients without speech, diagnosed with autism who communicate using facilitated communication. An average of five clients and their facilitators, the leader, and an assistant leader comprised the group. The themes that emerged and the group-development process observed paralleled regular verbal groups in many respects. The success of the project challenges accepted views of person labeled autistic as intractably and inevitably isolated and unreachable.

A simulation-based approach to forecasting the next great San Francisco earthquake.

In 1906 the great San Francisco earthquake and fire destroyed much of the city. As we approach the 100-year anniversary of that event, a critical concern is the hazard posed by another such earthquake. In this article, we examine the assumptions presently used to compute the probability of occurrence of these earthquakes. We also present the results of a numerical simulation of interacting faults on the San Andreas system. Called Virtual California, this simulation can be used to compute the times, locations, and magnitudes of simulated earthquakes on the San Andreas fault in the vicinity of San Francisco. Of particular importance are results for the statistical distribution of recurrence times between great earthquakes, results that are difficult or impossible to obtain from a purely field-based approach.
